captcha problem (rev. 58)

[peppolone]

I upgraded to the last rev, but the pligg captcha is always available in the admin menu
Available Captchas

* Pligg Default Captcha | Enable
* reCaptcha | Enable | Configure
* WhiteHat Method | Enable | Configure
* Math Question | In Use | Configure

and the whitecaptcha doesn't work, there is a problem with the image.
<img src="/modules/captcha/captchas/WhiteHat/CaptchaSecurityImages.php"/>
if i open the link i have this error
Fatal error: Call to undefined function: imagettfbbox() in /modules/captcha/captchas/WhiteHat/CaptchaSecurityImages.php on line 60

Thanks for the bug report, I forgot to remove the default module from SVN.
I had someone look at the Pligg and they made a change to the CaptchaSecurityImages.php thinking they were fixing a problem with Linux computability, but it seems they broke it altogether. Easy fix is to change

 realpath($this->font)

To:

 $this->font

This occurs on lines 61 and 64.
I will make the change to the SVN right now.

In the future please post bug fixes to Pligg Projects.

ok tnx, long time I'm on the forum, I had never seen that section
remove also

			<li>Pligg Default Captcha | {if $captcha_method eq "default"}<b>In Use</b>{else}<a href="module.php?module=captcha&captcha=default&action=enable">Enable</a>{/if}
				{* | <a href="module.php?module=captcha&captcha=default&action=configure">Configure</a> *}
			</li>

from captcha_home.tpl

Yeah, its kind of hidden in the tabs up top. We're trying to move all bugs and feature requests into there so that we can be a bit more organized. Projects offers a lot of great features that allow the developers to confirm, prioritize
and post fixes to problems.

I tried it but always
Fatal error: Call to undefined function: imagettfbbox() in /modules/captcha/captchas/WhiteHat/CaptchaSecurityImages.php on line 61

I'll test this out tonight or tomorrow morning. I reverted the changed code to what it was so it shouldn't have a problem. Maybe I missed something.

I just tested on localhost, and the image is displaying fine with the latest revision (60). Does line 61 of CaptchaSecurityImages.php read the same as below?

         $textbox = imagettfbbox($font_size, 0, $this->font, $code) or die('Error in imagettfbbox function'); 
  

[peppolone]

yes
$textbox = imagettfbbox($font_size, 0, $this->font, $code) or die('Error in imagettfbbox function');
This function requires both the GD library and the » FreeType library.
