   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**)
   I have the GD library class compliled into PHP, CaptCha finds TTF file, but on blog it says “No Truetypefont available for the CaptchaClass”

   Make sure the TTF files in the TTF Folder are readable by Apache/PHP (or public readable).
   Try to

   chmod 644 *.TTF

Being the lazy sod I am, this bugs me, so I thought I’d check out the competitors and see whether there wasn’t something slightly better that would Erroneously thinking the problem was there, I checked out hashcash,CaptCha! and SecureImage. Hashcash, claims 100% effectiveness so seemed like a good start, but I was completely unable to get it working despite following instructions to the letter. It was unclear to me whether I needed to also add in the md5.js which was

   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?

   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.

   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?

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

    ^ that should read: nested form’s

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

13. 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…

    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 !!!

    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?

    Octubre 6th, 2005 at 8.58 pm
17. 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.

    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.

    I installed Captcha 1.6 fine, ok to activate it. Ok to edit settings in the OPTIONS tab of WP. I created the TTF & TMP folders w/o a problem:

    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:

    And the page ends.

    bdk (23):
    Wow! 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.

    Octubre 11th, 2005 at 9.25 pm
26. 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.

    Octubre 12th, 2005 at 5.45 pm
27. 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.

    Octubre 12th, 2005 at 6.46 pm
28. 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.

    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!.

    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.

    hi again,
    i sometimes get a “Garbage Error”. maybe you could tell me, when this is supposed to happen ?
    it’s gone, as soon as the “tmp” folder gets emptied …

    Octubre 16th, 2005 at 12.47 pm
32. 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.

    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?

37. 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.

    Octubre 18th, 2005 at 3.48 pm
38. 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.

    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.

    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…

    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:

    You wrote me that you have discovered a problem with the random horizontal position, that might be related with my problem.

    (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.

    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?

    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
    Keep up the good work, this plugin was one of the major things missing in Wordpress.

    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.

    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.

    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! :()

    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: 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?

    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?

    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.

    Noviembre 1st, 2005 at 11.22 pm
70. 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.

    Noviembre 1st, 2005 at 11.55 pm
71. 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.

    [...] 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. [...]

    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.

    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.

    Noviembre 4th, 2005 at 1.44 pm
78. 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.

    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.
