Captcha! Plugin español 

Warning! CAPTCHA! is DISABLED on this site.
Even though this plugin is still maitained, I’m using another one. Read why.

You can also go to the phorum for help.

I wanted my WordPress to have one of those nice Captchas challenges to avoid spam.

There are already some of them, but I found them not suitable for my webhosting service (Secureimage), or a bit weak (Trencaspammer). So I started my own based on the HN Captcha PHP class. To see a demo of this plugin just try to enter a comment on the main page (Okay, still in Spanish. Bilingual web soon to come).

Needs the GD library class, a Javascript compatible browser and TrueType fonts in a server folder to work. You can download some of TTF (TrueType) fonts for free from Dafont. The more artistic the font, the better the challenge will be.
The plugin allows to request another challenge if the current one is illegible.

Hope you enjoy it.

  16. [Spain] Boriel says:

    I don’t see any error. The message “Oh, no, I cannot read this captcha…” is not an error. It’s an option given to the user to request another code, if the current one is too difficult to read. Your instalation is working ok.

    Hi – doesn’t work on my Wordpress (latest version 1.5.2) Gentoo Linux (**no X installed**)

    Muchas gracias por este plugin. Aunque todavia no tenía spam en mi nueva pagina, en mi vieja si que había mucho en el “guestbook” (lo que era un script muy sencillo que yo había programado como una primera prueba de PHP, sin protecciónes y tal). ¿Sabes si hay una protección como la tuya para un formulario de email también?
    Saludos. Stefan

  20. [Spain] Boriel says:

    Stefan, gracias a tí por usarlo.
    No conozco ningún plugin que haga eso. Si te refieres al contact form, igual se podría hacer algo para integrar ambos plugin’s de manera que el contact form tuviera un Captcha también.

  21. [Germany] Stefan says:

    Hace poco he utilizado un sencillo script de PHP pero debido a mucho spam lo acabo de borrar. Acabo de installar este plugin – me parece que es el mismo como el tuyo. Si encuentras una manera de integrar Capcha con ese formulario, me alegraría si me avisaras. :)

    Sorry, the code is stripped or lost. You can delete those top 2.

    There is a problem in 1.4

    I debug and found it easily..

    Here, replace Line 244, the PHP part with:

    /* echo captcha::version; */

    It prosesses the PHP in the HMTL comment. :d Also remove the / before .

    Oh also, the flipping is too strong… sometimes it turns it that u can’t know which came first.. you understand?

  23. [Germany] Jasmin Buchert says:

    Captcha totally breaks the site layout with Opera (tested with 8.50).
    It seems Opera doesn’t like the nested ’s:


  24. [Germany] Jasmin Buchert says:

    ^ that should read: nested form’s

    PS: Your captcha test is too hard for humans..

  25. [United States] Olajide Olaolorun says:

    Yeah.. what i was saying… too strong… mixes it up sometimes..

  26. [Spain] Boriel says:

    Jasmin, Ok. Opera doesn’t allow nested forms. And I don’t use it, so was not tested (in fact, the XHTML validator accepts it! 8O).
    Will try to fix it in the next release. Thanks. :)

    And the captcha difficulty is given by the TTF fonts you choose (check the other sites examples to see it clearer). I think I should use clearer TTF fonts too…

  27. [Australia] Nick says:

    Hey great plugin…I am getting the “Error! No TTF font found!No Truetypefont available for the CaptchaClass.” as well.

    Being fairly new to this could you provide a config.php that has been configured??

    I think I am missing some of the extra settings…the path to the fonts seems to be correct (available by browser) etc.

    Thankyou in advance.

    Hy!
    Thanks for the great plug-in!
    :?: There is one little problem with “the “Invalid Code”, Retry sequence”:
    If I enter a wrong code, the Javascript-alert pops up (that’s all ok until here). If I click “ok” on the javascript-alert, i get a 404-error message.
    Any ideas ? ( I use your plug-in on pages too … maybe this is the problem ???)
    anyways: muchas gracias for your idea !!!

  29. [United States] scud says:

    Like some others I’ve tried getting this to work, CHMOD’d the proper folders and fonts, and still get a Cannot find TrueTypeFont for CaptchaClass. Both the font and font folders need to be CHMOD’d to 644 correct?

  30. [Spain] Boriel says:

    scud: Not exactly.
    You have to chmod 755 for TTF folder, and then CHMOD 644 for *.TFF files.
    You also have to chmod 777 TMP folder, and then it’s a good idea to also chmod +t TMP folder.
    Try this and tell me.

  35. [Spain] Markus says:

    Installed 1.6 and worked like a charm. Though, I’ve observed it still breaks the XHTML validator, so I made a couple of changes to hn_captcha.class.php

    Fix ampersands in form actions:

    Find this line:
    $this->QUERY_STRING = strlen(trim($_SERVER['QUERY_STRING'])) > 0 ? '?'.strip_tags($_SERVER['QUERY_STRING']) : '';

    Replace with:
    $this->QUERY_STRING = strlen(trim($_SERVER['QUERY_STRING'])) > 0 ? '?'.str_replace('&','&',strip_tags($_SERVER['QUERY_STRING'])) : '';

    Fix dummy form:

    Find this line:
    $s .= ' ';

    Replace with:
    $s .= 'QUERY_STRING.'" method="post"> ';
    $s .= '';

    Hope that helps someone. ;)

    When I turn off Captcha, WP displays fine, including the footer of the page. When I turn Captcha on, the page abruptly ends and does not display the footer area of WP which should include the Captcha fields.

    I turned on debugging and got:

    GD (v2.0.28) Enabled in PHP (v4.3.11)

    Any ideas?

  38. [Spain] Boriel says:

    bdk (23):
    Wow! 8O This is a great debbug info! :)
    After reading that, I see everything it’s in place. Does your GDLib have FreeType support?

    Have you tried to left blank (empty) the TTF font list in the Option panel and then update options? After that, the TTF list should appear automathically.
    Try this and tell me.

  39. [United States] bdk says:

    Yes, I had removed the entries from the font field in WP and your Captcha readded all of the fonts w/o a problem.

    How do I tell if GDLib has FreeType support?

    A phpinfo() shows:

    GD Support enabled
    GD Version bundled (2.0.28 compatible)
    GIF Read Support enabled
    GIF Create Support enabled
    JPG Support enabled
    PNG Support enabled
    WBMP Support enabled
    XBM Support enabled

    Thanks again.

  40. [Spain] Boriel says:

    bdk (25): using phpinfo() as you did!
    Your GDlib does NOT have FreeType support enabled. Unfortuntately, this is required to read and use the .TTF fonts. See if you can enable it.

  41. [United States] bdk says:

    Awesome!

    Got FT2 compiled and working with GD & PHP and works great.

    2 suggestions, allow all of the $CAPTCHA_INIT array to be configured via WP. Second if someone were to get the Captcha code wrong, bring them back to the ‘Leave a Reply’ section with their reply already typed in, it was erased.

    I just got your Captcha wrong and had to retype everything. This time I’m going to copy this into my clipboard in case I get it wrong again.

  42. [United States] bdk says:

    And thanks again for all the work you put into the WP-Captcha, I can see it being an included plugin in future releases of WP.

    Great job!.

  43. [Spain] Boriel says:

    bdk
    (27):
    Most of the features are or will be configurable from the options panel (well, that’s the idea).
    And regarding to your 2nd, the plugin already does that (I’ve tested it in your server, and it worked to me): You don’t loose your comment content in case you enter a wrong captcha code (or at less, you shouldn’t).
    It it start to fail, plase mail me to see if we can debug it.
    (28): You’re welcome. Thx for your suggestions. :)

    Thanks in advance

  48. [United States] Rob says:

    Ok, I have both FT2 enabled now on my server. It shows up in phpinfo() as such:

    FreeType Support enabled
    FreeType Linkage with freetype

    Have the plugin enabled, but nothing shows up on comment sections. Don’t I need to add anything to the comments.php file of my theme?

  49. [Spain] Boriel says:

    el tiki (30):

    This error should never happen. Garbage Collection means the max number of cached captcha-images has already been generated, and the hn_captcha class cannot delete them.

    Empty the tmp folder completely, and make sure the Webserver (Apache/Php) can delete files in the tmp directory (it should already, since it can create files).

    Hmmmm. Really, odd. :?

    Try to reproduce the error: The max number of cacheable images is stored in the file captcha.php, into the function hn_new_captcha(). The parameter “collect garbage after” (20 by default) tells how many images can be stored in the tmp folder. When this limit is reached, older images are deleted. This procedure seems to be failing in your website.

    I will investigate the problem this evening, but would be difficult to reproduce it in my server. Meanwhile, you can enable the “debug” parameter in the above function and try to reproduce the error. This might give you more information. Remember to disable “debug” after that.

  50. [Spain] Boriel says:

    Rob (35):

    Upload some .TTF (True Type Font) files to the TTF directory (I guess you have already done that).

    Then go to the Options panel, empty the TTF font list, and update options. After that, the TTF files should be detected automatically.

    Try this, and tell me.

    By the way, you have to be logged out of your server, since logged in users are *trusted* and captcha won’t be showed to them.

  51. [Spain] Boriel says:

    Alec Saunders (33):

    I suppose it shows only two digits because you configured that way in the Options panel. But, on the other hand, the size of the image has changed. Did you edited the hn_captcha_class.php or any other file by hand?

    Some parameters are a bit critical. That’s why they’re not available yet in the options panel. If you did change the image size, digit rotation or separation, please, leave them as they were originally (or reinstall the plugin files overwriting the current ones).

    Try this and tell me.

    Note: If you want to use less digits and smaller image size you have to be carefull with the digit separation, rotation and even the TTF font size. The author of the hn_captcha_class tuned this parameters a lot before releasing it, I suspect.

  52. [Serbia And Montenegro] paleksic says:

    Boriel thanks for quick email bro, i have it working now. You was right i overlooked directory names. Keep us informed i’m subscribing here ;)

    cheers!

  53. [United States] David says:

    Boriel, I have the same problem as #33, Alec Saunders. The Captcha! image shows up below my comment form, but all letters are displayed on top of each other in the left-hand side of the image. I have set my only font to arial.ttf, and have experimented with the number of characters displayed. The problem remains whatever number I use (using 5 now). I see Alec has solved it by setting the number of characters to 1 on his blog :-) Any hints to solving this issue?

    By the way, I initially got the “No Truetypefont available for the CaptchaClass.”-error too. I solved this by making the “TTF Files:”-field in the Captcha-options of the WordPress admin pages empty. When you update the options, you will see that Captcha! automatically fills in this field with the fonts in your fonts directory. It is described somewhere in the readme or web pages but I overlooked it initially, perhaps this comment can help some people.

  54. [United States] Eric says:

    I installed Captcha and configured the options (tmp path, truetype font, etc.), but it doesn’t show up for me. I made sure to activate it. Any ideas why it isn’t showing up at all? GD is installed with freetype support. Thanks for any help!

  55. [United States] Outlandish Josh says:

    Installed and seems like it wants to work, but when I enable the plugin the html output of a comments page is incomplete. The last thing wordpress sends to the browser is the submit button. PHP doesn’t throw any errors to the browser or to the apache error log, so I’m in the dark here…

  56. [United States] Outlandish Josh says:

    FYI — the problem I experienced was fixed by rebuilding PHP with freetype enabled.

  57. [Russian Federation] Kostya says:

    Uploaded fonts (plug-in detected them). Set permissions for folders manually. And all what I have now is CaptCha! section in comments with a strange “absolute” look like image code: “http://www.myhomepage.com/home/u12345/myhomepage.com/tmp/hn_captcha_b7a8d.jpg”. Absolute path to my temp directory is “/home/u12345/myhomepage.com/tmp/”. And the right image code, i think must look like “http://www.myhomepage.com/tmp/hn_captcha_b7a8d.jpg”. Isn’t it? Ooh… And images is not generating at all (check it via FTP).

    Here is gd lib section in my phpinfo:

    GD Support enabled
    GD Version bundled (2.0.28 compatible)
    FreeType Support enabled
    FreeType Linkage with freetype
    GIF Read Support enabled
    GIF Create Support enabled

    Do I need to add anything to my comment template to display the captcha interface? I followed the README directions and all the options seemed to be set fine (plugin discovered the fonts in my dir, paths are CHMOD’d properly, etc, etc) but there is no Captcha on the comment form.

  60. [Spain] Boriel says:

    matt (45): You discovered the solution, but I post it here for anyone else who might find it useful. The problem was your theme has a bug in it. The tag

    <?php do_action(’comment_form’, $post->ID); ?>

    must exist and be placed just before </form> html tag in your comment template file.

  61. [Belgium] David says:

    Boriel,

    You wrote me that you have discovered a problem with the random horizontal position, that might be related with my problem. You suggested that I download version 1.7 to see if that fixes the problem. I have done a few tests with 1.7, but the problem persists. Perhaps Alec Saunders has found something new?

    Meanwhile use the previos version 1.6 instead. This should work Ok.

    Hola. No tengo ni idea de qué es una biblioteca de clases GD de PHP pero trataré de instalar tu plugin porque estoy recibiendo millones de spams. Gracias por el trabajo

  70. [Spain] enrique says:

    Nada. NO me funciona. ¿Tal vez porque uso WP 1.2?Creo que no quedan claras las instrucciones de instalación ¿a qué carpeta va cada archivo? ¿dónde están las Captcha! Options (no en mi Options page).

  71. [Spain] Boriel says:

    Enrique:

    (55):
    Es difícil si no tienes experiencia con el PHP. La biblioteca GD permite a PHP hacer gráficos en tiempo real.

    (56):
    Puede que no sea compatible con WP 1.2. Te recomiendo que te actualices a WP 1.5.2 ha mejorado muchísimo y corrige fallos de seguridad. La instalación es como sigue:
    a) Copias el fichero captcha.php a la carpeta de plugins.
    b) Copias la carpeta captcha y todo su contenido a la carpeta de plugins.
    c) En el panel de administracion, debería aparecerte el plugin desactivado. Lo activas.
    d) Una vez hecho esto, en las opciones, debes configurarlo.

    Mira si puedes llegar hasta aquí.

  72. [Spain] enrique says:

    Boriel: muchas gracias por la respuesta. Hasta donde dices llego sin problemas, es sencillo. Después de activar el plugin me voy a opciones y no aparece nada de Capcha, sólo las de siempre. Imagino que el problema viene por la compatibilidad con el WP 1.2
    Sobre la biblioteca GD : ¿la tengo por defecto o tengo que instalar algo?

  73. [Germany] AoP says:

    Boriel, just another thankful comment from Germany for your plugin. It took me a while to get it working, though I don’t yet know what went wrong (is it possible that underscores in the ttf-filenames are not allowed/possible?) but now that it’s done it’s really good looking and hopefully as effective :D
    Keep up the good work, this plugin was one of the major things missing in Wordpress.

  74. [Spain] Boriel says:

    Aop (59):

    Underscores are allowed in TTF filenames (or at less, they should).

    Anyway thanks for you comment. If you want to be linked from this page as an example page, don’t forget to put your URL.

  75. [Netherlands] Marjan says:

    Great plugin. Works like a charme.

    I’ve got the latest version and would like a Dutch version / language file. If possible: Where do I change / edit the englisch- or spanisch or german text?

    Greetings.

  76. [Netherlands] Marjan says:

    Never mind. :oops: Found it in ‘hn_captcha.class.php’. Thanks anyway

  77. [Germany] Andreas Wacker says:

    Sorry,
    unable to get it to work. Maybe you want to give people an example directory configuration, including the html root.

    Sad if the anti spam captcha (that works great if installed by somebody less stupid than me, I am sure) takes more time than the dreadful spam.

    Yes, I did read all this pages, enabled debug, messed with the php code, but still can not make it work right. Again: That is me and my install. A real example of a working config would have helped tremendously. It’s those missing 3% that render this great plugin useless for me.

  78. [Spain] Boriel says:

    Andreas (63):

    1) Describe your problem: What is your problem exactly? What did the debug info said?
    The html root is obtained automatically.
    2) Leave blank (empty) the directories in the captcha options. And press UPDATE. They are configured automatically to suitable values. You can use those folders, and give the right permissions (Read + Write for TMP and Read for TTF).
    3) Upload some TTF files to your ttf folder (they must be readable).
    4) In the options panel, leave blank (empty) the TTF files list, and UPDATE. It should be configured automatically. If it is, then the TTF directory is Ok.
    5) LOG OUT of your admin panel, and try to post a comment (Logged In users are trusted, and captcha won’t appear for them).
    6) Use WP 1.5.2 (Ok, this should not be a problem, anyway, but 1.5.1 has a bug and can be hacked by malicious users. Look out! You can loose your database during upgrade! :( )

  79. [United States] Ido Dubrawsky says:

    Hi,

    I’m trying to implement captcha-1.8 on a Solaris 9 webserver which has multiple web sites on it (i.e. virtual servers). I have Apache 2.0.50 with PHP 4.4.0 configured as follows:
    ‘./configure’ ‘–prefix=/opt/depot/php-4.4.0′ ‘–with-apxs2=/opt/bin/apxs’ ‘–with-jpeg=dir=/opt’ ‘–with-zlib=/opt/depot/zlib-1.2.3′ ‘–with-gd=/opt/depot/gd-2.0.28′ ‘–with-jpeg-dir=/opt/depot/jpeg-6b’ ‘–with-png-dir=/opt/depot/libpng-1.2.7′ ‘–with-xpm-dir=/opt/depot/xpm-3.4k’ ‘–with-freetype-dir=/opt/depot/freetype-2.1.10′ ‘–with-ttf=/opt/depot/freetype-2.1.10′ ‘–enable-gd-native-ttf’ ‘–with-mysql=/opt/depot/mysql-4.1.4a-gamma’ ‘–with-zlib-dir=/opt/depot/zlib-1.2.3′

    I don’t get any captcha images in the comment pages which results in no comments being added. I’ve turned on DEBUG in captcha and this is what it says:

    -Captcha-Debug: Check given TrueType-Array! (1)
    -Captcha-Debug: Valid TrueType-files: (1)
    -Captcha-Debug: Set current TrueType-File: (/opt/www/dubrawsky_org/TTF/1942.ttf)
    -Captcha-Debug: Set number of noise characters to: (54)

    -Captcha-Debug: Fill background with noise: (54)
    -Captcha-Debug: Fill forground with chars and shadows: (6)

    And that’s it. I’m at a loss as to why captcha is not working. Any suggestions?

  80. [United States] Ido Dubrawsky says:

    A quick follow up: I’m using WordPress 1.5.2 with the default theme.

    Ido

  81. [United States] Ido Dubrawsky says:

    I’ve isolated the problem to the hn_captcha.class.php script at the @ImageJPEG($image,$this->get_filename(), $this->jpegquality); call. It appears to exit right after this call and never completes the script. Any ideas?

  82. [United States] Thomas Leavitt says:

    Had been using SecureImage, but wound up encountering the problem of ImageMagick not having freetype support compiled in… so I installed this instead. Works fine. Would be nice if the /tmp directory could be a system directory, and not a published directory under the WWW root.

    There is a buglet, however: in WP 1.5.2, I noticed that having the system attempt to automatically extract the list of fonts produced an error: didn’t save it, but something to do with the “implode” function. I bypassed it by simply extracting the list of fonts myself, and inputing them in directly.

  83. [Spain] Boriel says:

    Thomas (68):

    1) Regarding /tmp directory, it must be a published directory. The images must be accesible via WWW, so they can be displayed as inline <img… / > images: This implies the tmp directory must be published. You can use another directory (NEVER publish system /tmp since it has some PHP session and other sensitive info there and could be a security breach). You can publish another directory in httpd conf or simpler, using symbolic link (ln -s) outside your document root.

    I have a way to solve this, however. It will be done in a future release.

    2) I use WP 1.5.2, as many others, and worked fine for us. If you can reproduce the bug, please tell me. If you enter the comma separated file list, then it won’t be automatically detected, as you did, and it will be saved as is.

  84. [Spain] Boriel says:

    Ido (67):
    Your tmp directory is OK (permissions and so on).
    Something is prevented to write the .jpg files there. But don’t know the reason. :?

    1) Check if the permission are OK, but I guess they are since hn_captcha_counter.txt exist.
    2) Check if your GD have JPEG enabled:
       <?php if (imagetypes() & IMG_JPG) echo "JPEG Support is enabled"; ?>
    3) Also put this: error_reporting(E_ALL ^ E_NOTICE); before the @ImageJPEG function call to see if any error msg is output.

  85. [United States] Ido Dubrawsky says:

    I found the problem. My gd library didn’t get compiled with jpeg support (I thought it was but it didn’t). I had to actually recompile the jpeg library first, then the gd library, then PHP and the everything works great. This is awesome. I look forward to less blog spam with captcha. Thanks!

  86. [United States] Ido’s Blog » Blog Archive » Comments are back…with a twist says:

    [...] I got tired of the blog spam from the on-line gambling sites and the Cingular ringtones folks and have installed the Boriel’s wonderful capcha plugin for Wordpress (yes, that’s how he spells it…in actuality it’s written as CAPTCHA). What is CAPTCHA? Captcha is the acronym for “Completely Automated Public Turing test to tell Ccomputers and Humans Apart.” You can find more information about it here. Now, if you want to submit a comment on my blog entries you will have to pass a reverse turing test. It’s simple…just put in the numbers shown in the graphic below your comment and press submit. If the numbers entered match the numbers in the graphic then the comment is accepted. The graphic is not machine readable so blog spam bots cannot parse it to get the numbers. Now, I had one problem with getting the capcha plugin to work — the graphic wouldn’t show up. It turned out that I needed to recompile my libjpeg library as well as the gd library and PHP in order to fix the problem. Now it works great. [...]

  87. [United States] Ido Dubrawsky says:

    I’ve seen some comment spam come through today even with the capcha plugin active and working. All of my testing has shown that comments must have the captcha code added. Could this be actual live people spending time inputting this spam? Is there anyway to tell? I guess I could look at the Apache logs but I was wondering if there’s a way to log things through the plugin or through WordPress.

    Just wondering.

  88. [United States] Ido Dubrawsky says:

    Turns out it’s trackback comment spam. It has nothing to do with capcha.

  89. [Spain] Boriel says:

    Ido (73), (74):
    I solved it using TrackBack validator plugin (see http://idli.cs.rice.edu/~dsandler/trackback/trackback-validator-plugin/).

    This will hide trackbacks not really linking to your site, but won’t delete it from your database. :|

  90. [Singapore] Gary says:

    Hi.. I am relatively new to wordpress and am having trouble installing this plugin.
    I have chmod’ed my two directories as advised, and the options panel is even able to update the .ttf list automatically, meaning it can access my font files, right? Yet when I log out and try to post a comment on my site, I get the message that no Trutypefont is available for the captcha class. I really don’t know what is wrong! please help me if you can. thanks.

  91. [Spain] Boriel says:

    Gary (76):

    These have been stated in the comments area. There main causes for this usually are:

    1) Bad chmod permissions (You see the .TTF list, so I guess they are Ok)
    2) Your PHP version does not have GD enabled
    3) Your GD-lib version does not support TTF.

    I’m preparing version 1.9 that will check for this automatically.
    Meanwhile, create a simple web page, named, for example test.php, with a sigle line:

    And view it with your browser. Search for “GD”, and tell me what it says about it.

    FYI, Captcha! version 1.9 doesn’t seem to be working with current SVN version of Wordpress (1.6-ALPHA-2-still-dont-use). It may be too early to be testing it, but you might want to check it out. The most obvious problem is the TrueType folder path, which is not being saved.

    Yes. Some themes are buggy, and do not call some wordpress events.
    It’s explained in answer (44):

    To fix your wrong theme, simply add

    <?php do_action(’comment_form’, $post->ID); ?>

    just before the </form> tag in the comments.php file of your theme.
    This will fix it, so you can use your favourite theme with captcha.

    Hi Boriel, I installed your plugin to get rid of the spam comments on my blog. Thanks to your plugin the spam is reduced really a lot, but still I get something… I searched some artistic fonts but it’s not enough: I receive every day a spam comment from the “texas holdem poker” guy.

    Do you also receive such comments? If not, can you please share the fonts that you are using for your captcha challenge?

    Thanks for letting me (us) know.

    Sincerely,

    Paolo

    [...] Final note, hopefully, on the comment spam and trackback issue—I found a different bot check software called Captcha! that still provides the security of random image generation to prove human commenting but that also allows continued trackback capability.

    The robots are winning — after installing this plugin I had a blissfully spam-free month, but now they’ve started up again. I get 30+ comments overnight, all from one source so it seems that someone’s bot has puzzled out a way to beat your system.

  137. [Spain] Boriel says:

    (122) Outlandish Josh:
    Ok, let’s study it.

    1) First of all, ensure they’re not trackback comments (referal spam). I use Trackback Validator and works fine to me. Captcha does not filter trackbacks nor pingbacks.

    2) Send me some comments (via email/contact form) that have bypassed the captcha.

    3) Change the fonts of your site from time to time. Enlarge the size of the code (6 or 7 digits), and use a wide variety of fonts.

    The plugin is supposed to work with Wordpress 2.0. Other people are already using it. Can you tell me a bit more about your problem? I think it could be a setup issue rather than a WP 2.0 compatibility one.

    On the other hand, Akismet plugin is already included in Wp 2.0, and it’s really effective against spam.

    – Include this tag in your theme’s comments.php just before “/form” HTML tag.

    TMP permisions were wrong (044). I CHMOD to 777. Garbage error corrected.

    THANK YOU FOR THIS PLUGIN!!!!!!!!!

  175. [United States] Robert Simmons says:

    I had the same problem that was stated in comment 153. It wound up being a problem with the fact I am using a WordPress option to reformat my permalinks. This creates an .htaccess with mod rewrite behavior in it to reformat the URLs. When the plugin was using $_SERVER['PHP_SELF'] to determine the page to which to return, it got “index.php” instead of the post specific URL. I changed all instances of $_SERVER['PHP_SELF'] to $_SERVER['REQUEST_URI'] in both captcha.php and captcha/hn_captcha.class.php and everything works fine. The only remaining problem is that the limit on retries seems to not be working. I can live with that for awhile.

    Again, although this worked for me doesn’t mean it’ll work for you, but I thought it might be helpful to some people.

I did a quick search of the plugins available for WordPress and found a promising looking comment spam prevention plugin named Captcha. [...]

  177. [Spain] Boriel says:

    Robert (160): Right, Robbert, using $_SERVER['REQUEST_URI'] will work for most cases. Some people (Derrick, 143) says it does not work for him.

    I think the very real solution is to use safe_link() function instead of permalinks. The following will be included in captcha 2.0:

    <?php
    // Insert this function in captcha.php file ....
    function back_url() {
    	global $post;
    	
    	$result = get_settings('home') . '/' . get_settings('blogfilename') . '?';
    	
    	if ($post->post_status == 'static')
    		$result .= 'page_id';
    	else
    		$result .= 'p';
    			
    	$result .= '='.$post->ID;
    	$sep = '&amp;';
    
    	foreach ($_GET as $k => $v) {
    		if ($k == 'p') continue;
    		if ($k == 'page_id') continue;
    		if ($v == '') continue;
    		$result .= "$sep$k=$v";
    	}
    
    	return $result;
    }
    
    // End of new code
    ?>

    Those who has permalink problems should try this fix.

    I’m having the same “new ID” problem as others. I updated the back_url function as described above, but it did not help. It does not appear to have caused any issues with my theme, though.

    I’m using Wordpress 2.0.1 on Apache 1.3 with the built in Captcha 1.9. It runs on Debian 3.1 from packages, except for all PHP apps and PHP itself, which is version 4.4.2 compiled from source, plus Zend Optimizer 2.6.2. I can send you phpinfo() separately if it is needed.

  186. [Spain] Boriel says:

    elyograg (170), I copied an old version of back_url(). Try now, and copy function from comment #165.

  188. [United States] Seth says:

    fantastic!

  189. [Spain] Boriel says:

    elyograg (172):

    I visited your blog and test it.

    It’s working for wrong codes (that is. If the user enters wrong code,
    it goes back to the right page, and the comment is preserved).

    But NEW ID button is not working. To fix-it, edit file
    hn_captcha.class.php, line #489, which reads:

    <?php 
    // This is the current code at line #489 
    $s .= '<form style="display:inline;" name="captcha2" action="' .
    $_SERVER['PHP_SELF'].$this->QUERY_STRING. '" method="post">' . "\n";
    ?>

    And replace it with:

    <?php
    // Replace the above with this one:
    $s .= '<form style="display:inline;" name="captcha2" action="' .
    captcha::back_url() . '" method="post">' . "\n";
    ?>

    This will fix NEW ID button.

    [...] So, what to do? Well, there are a few options. Looking in the Wordpress Plugins Database, there are a lot of anti-spam packages. What I want is more of a capcha functionality, where the user is presented with an image that they must mentally translate to a string and enter that in. Very difficult for a program to do, but I’m sure spammers are working on OCR techniques, not to mention employing real people. There’s a Capcha plugin for WP, but it requires a little work to set up.

I know that who ever is writting the bots that spam is only wanting a pay check but I think youre an asshat for doing it. Take your talents to somewhere else.

    hy boriel!

    after a year of using your great plug-in, I’m getting my first flood of Spam. seems like they found an OCR-technique to read the captcha-image … I was allready using hard-to-read fonts … if I make them harder to read, no one will post anymore, I guess … :cry:

  221. [Spain] Boriel says:

    Keep in mind these:

    1. Check they’re not pingback nor trackback (referral) comments (I use trackback validator for this)
    2. Check they’re not registered users (If you allow users to register your blog). Registered users are not changelled.
    3. Check that your “Captcha Secret” key is not the default one. The captcha secret must be a long passphrase only known by you. Change it, and see if you are receiving more spam.
    4. Use more than one font. You’re only using 1 font, this make easier your captcha to be broken. Use 3 fonts (I can suggest you some of them from Dafont). Choosing different fonts makes your captcha stronger.
    5. WP 2.0 seems to have some security bugs which could allow people to bypass captcha (and other filters). Upgrade to WP 2.0.1

    Hope these helps… :?

    I can comment without having to verify the characters. Any ideas where I am going wrong?

  272. [United States] David says:

    Okay, this is what I’ve done, I apologize for not including all of this in the initial post, I’ve been having problems actually getting the comment to post, and I got tired of retyping everything. I’m using Wordpress 2.0.2

    1)Installed and activated the plugin per the instructions in wp-content/plugins/captcha/captcha.php

    2)Verified that the permissions on the wp-content/plugins/captcha folder are 755 (though I tried 775), and that the owner is the web server user

    3)Verified that the permissions on the files in the captcha folder (captcha.php and readme.txt) are 644 (though I tried 755)

    4)Verified that the permissions for the fonts directory (wp-content/fonts/) and the 6 fonts in the directory are 755. There were once 60 or so fonts in there, but I’ve trimmed this down to 5 or 6 useful ones.

    5)Turned on debuggin in captcha.php and got the following output:

    -Captcha-Debug: Current public key is 0.

    -Captcha-Debug: Expire time is: 2006-05-24 21:09:16
    -Captcha-Debug: Generate Keys, public key is: (cf635)
    -Captcha-Debug: Generate Keys, private key is: (347e2)
    -Captcha-Debug: Current try is 1.

    -Captcha-Debug: Generate a string which contains current try: ()
    -Captcha-Debug: Expire time is: 2006-05-24 21:09:16
    -Captcha-Debug: Output Form with captcha-image.

    6)Checked the gd section from phpinfo() and got the following output:

    -Captcha-Debug: Current public key is 0.

    -Captcha-Debug: Expire time is: 2006-05-24 21:09:16
    -Captcha-Debug: Generate Keys, public key is: (cf635)

    -Captcha-Debug: Expire time is: 2006-05-24 21:09:16
    -Captcha-Debug: Output Form with captcha-image.

    7)Deactivated and reactivated the plugin multiple times.

    After all of this I’ve not been successful in getting the captcha image to show up. The form is there, but the image just shows the placeholder and placeholder text. I’m out of ideas. Any suggestions?

  273. [Switzerland] tin says:

    I hadn’t even thought to try that. I’ve replaced captcha.php from 2.3 with captcha.php from 2.2 and it’s displaying the image just fine for me as well. Now to figure out what’s wrong with 2.3 on my system.

    Thanks, Tin. ;)

  279. [Switzerland] el tiki says:

    thx for the work-around … i had the same problem with the pictures not showing anymore … :x

  280. [United States] David says:

    Boriel,

    Thanks for the great plugin! A couple of things:

    I was having massive problems with not all of the digits showing up on the pictures (digits getting pushed off of the frame, or being the same color as the background, or something). Turning off sine wave distortion helped a little, but I still had a few problems. Turning off “use different color” seems to have fixed the problem. FYI for anyone noticing these problems.

    I also noticed that initially after I would enable the plugin, I ended up losing my admin panel. It just wouldn’t load. Some snooping finally showed me that PHP was exceeding the allowed memory with the plugin loaded. Increases the maximum memory allowed in php.ini (default is usually 8M) solved that problem.

    I just figured I’d pass this on to anyone having problems.

  281. [Spain] Boriel says:

    #264, Dave: Keep in mind that the more plugins you have installed in your WP blog, the more memory they take, so it’s not a problem of captcha itself. That is: if you uninstall other plugins and install captcha, it should work ok too.

    Anyway, I think 8Mb is to little. I’m not sure how much I’m using, but I think it’s 32 Mb.

    I think it happened with captcha simply because it was the last you installed before running out of memory (or did you installed another plugin after it)?

    By design: Captcha.php uses very little memory in the admin panel. Only the image generation takes some memory (about 32Kb, I think, but not sure), and it doesn’t happen during the admin stage, but during comment-form rendering phase. This means it cannot affect your admin panel.

    > I just figured I’d pass this on to anyone having problems.

    Regarding the fonts sometimes not appearing, it’s a problem of the .TTF fonts you choose (and the PHP GDlib). When selecting a font, it might be flawed and sometimes, for little sizes, it does not display the digit correctly or even does not display it at all (in fact, I have tested many fonts). Don’t know why… :(

    For the fonts I’m currently using, they display always. It’s not a related to sine-distortion or color effects (they’re applied after the digits code have been rendered). So enabling/disabling them won’t affect this issue.

  282. [Spain] Boriel says:

    Warning! About Captcha! memory usage.

    I got really concerned about David’s last comment and made some test, to see:

    1. How much memory was my WP system using.
    2. How much memory Captcha! uses.

    PHP has get_memory_usage() function enabled on systems with memory-limit restriction. My web-hosting *does not* has such restriction!

    So I use that function at home (I have my WP replicated at a local home server, for testing purposes). And these are the results:

    26853376 bytes => 25,6 Mb With Captcha! plugin enabled
    26406912 bytes => 25,2 Mb With Captcha! plugin disabled

    Diference:
    446464 bytes => 0,45 Mb (this is the average of memory Captcha! plugin takes)

    These are averages, since memory measures varies a little from time to time (the variation is about 1Kb, anyway).

    Notice, however that my WP system uses about 26Mb of memory (and the more plugins you activate, the more memory it takes). 8Mb is too little. I guess you were about 8Mb before installing captcha, and once you installed it, the server dind’t allow you to execute. ;)

  283. [United States] David says:

    Boriel,

    Thanks for the response. Yes, I’m sorry, I didn’t mean to make it sound like it was a problem with the captcha plugin. It is an issue of having a lot of plugins loaded, and I was apparently already near enough my limit that some little bit of the captcha plugin that was being loaded with the admin panel was enough to set it off. I tested this repeatedly: Turn on the plugin, admin panel goes away, rename it, admin panel comes back. I’ve tested this repeatedly with other plugins too, none of which seem to directly affect the admin panel, and they do the same thing. Boriel is right, this is not a captcha specific problem, I just noticed a few posts on the wordpress support forums about this problem and it took me a while to figure out what might have been going on. It seems to be something to do with when/how Wordpress loads plugins or something. I don’t know enough about php to really analyze thep problem. I posted a response there, and thought I’d post the tip here if anyone else was having the same problem I was.

    As for fonts, thanks for the tip, I really appreciate it. Question about how the plugin uses fonts. Does it pick a font, and then use only that font for a single captcha image, or will it randomly pick a font for each digit within an image (so, up to 5 different fonts, if you have that many installed)?

    Thanks for the attentive, quick responses. This really is helpful.

    Regarding TTF fonts: Yes, the plugin choses a random TTF font among the available ones for each digit, so they might repeat or not (randomness increases security). I currently have 2 fonts installed. You might notice they both are used randomly.

Aber leider ist der Kampf gegen den SPAM auch zu einem Katz und Maus Spiel geworden – offenbar rentiert sich die Entwicklung immer neuer Methoden, überall (in EMails, in Foren, in Gästebüchern, in Blogs) diese störenden Quatsch abzuladen. Mich würde ja schon mal interessieren, ob überhaupt jemand auf solche SPAM Angebote eingeht – aber ganz offensichtlich doch. Wie heisst es doch immer so schön: Der Markt bestimmt.

  335. [Spain] Boriel says:

    Yuji (#337):

    Recuerda que el captcha solo se muestra a usuarios no registrados.

    Comprueba que el plugin está en el directorio plugins/captcha/captcha.php, si no es así, desactívalo, muévelo a ese directorio, y vuélvelo a activar. Esa suele ser la causa más común (en el breve fichero readme se insiste en que ese es el directorio).

    Si sigue fallando, activa el flag “DEBUG” = true en el código de captcha.php. Mira la página y los errores.

  336. [Spain] Boriel says:

    Pero (#338):

    Puedes elegir cualquier directorio dentro del wordpress. De forma predeterminada, el plugin elige unos. Para ver cuales son, deja en blanco la opción del directorio, y guarda la configuración (entonces aparecerán los directorios por defecto).

    Ese directorio debe estar en tu host. Si no sabes encontrarlo, pregunta al administrador de tu Hosting. El podrá ayudarte, ya que esto depende de cada hosting.

    I’m sorry to bother with this again even though two users already seem to have had a similar problem:

    And I really think I have it in the right folder:
    wp-content/plugins/captcha/captcha.php
    together with the fontfile in the same-folder

    The interesting thing is: in my local-php-setup (standard under Mac OS X) it works without any problems, but online it doesnt (same relative folders, same fontfile…)

    [...] Kapcsa By JoeP A spam elleni harc jegyében megint kavartam a blogon. Az Akismet lehet, hogy jó, de nekem decemberben napi 30-40 spam-et engedett át – és hiába fogott meg mellette százat, hagyott azért munkát nekem is. Ekkor jött a Hashcash, mely az Akismet-tel párban abszolút remekül dolgozott. A Hashcash olyan napi 10 szemetet engedett át, azokat meg az Akismet csípte nyakon. A védelmen egy hónap alatt olyan 3 spam jutott át. A gond csak az, hogy ehhez bekapcsolt javascript kellett a látogató részéről – és némi szerencse. Eddig kétszer fordult elő ugyanis olyan anomália, hogy valakinek a kommentje ‘elveszett’ az éterben: az illető elküldte, a Wordpress tudomásul vette, a blogon meg is jelent, hogy van komment az íráshoz – de az mégsem érkezett be az adatbázisba. Emiatt úgy döntöttem, hogy szép az, ami egyszerű: kikapcsoltam mindkét védelmet és feltelepítettem egy Captcha! plugint, dacára annak, hogy a szerzője mindenáron megpróbált lebeszélni róla. Mostantól itt is be kell gépelni azt az öt karaktert, melyet meglehetősen meggyötörve tesz ki egy grafikára a plugin. [...]
