Captcha using TTF & GD

[a_berezin]

My feedback: maybe you can find better color for the fonts?

You have enough of knowledge to self-make it. See

	var $backgroundColor = array(array(220, 220, 220), array(255, 255, 255));
	var $linesColor = array(array(150, 150, 150), array(185, 185, 185));
	var $textColor = array(array(30, 30, 30), array(199, 199, 199));

Nevermind nevermind

Yes! The changes above to /includes/classes/captcha.php
solved my problem of the characters displaying.
Looks good!
So issues on PHP 4.44. shop are solved.

But still no image displays on PHP 5.1.6 shop.

My host says problems are with the script not their service (of course they would say that). If I can point them in the right direction they will help but I'm clueless.

I forgot to include error log entry:

File does not exist: /home/account/public_html/403.shtml
client denied by server configuration: /home/account/public_html/shop/includes/templates/my_template/images/index.php

Does this indicate a server security setting amiss or any other ideas?

I asked host to look in their mod_security rules but that came back negative.

Anyone else have issues with this script on PHP 5.1x ??

Just checking before I fire my web host

Host says they observe no file index.php created
in /home/account/public_html/shop/includes/templates/my_template/images/

Is this index.php suppose to be created (and destroyed) on the fly each time the captcha image is generate?. Or is index.php only created in memory, not ever written to disk?

My web host says that file needs loaded into the images directory, so that is my problem. But the mod does not come with index.php file.

Is there an ez method availabe to adapt the mod to write the file to disk (as a png, gif or jpg) just to ensure the image is created.

My host asked if there was a "debug" version of the script available.

CAPTCHA don't create, use, need and etc index.php in any directory. And also CAPTCHA don't use/read/wrtite/touch any /images/ directory at all.

It is possible, but I it shall not do it.

I jumped to conclusions. After making the edits recommended the CAPTCHA module is working. But seven new errors showing up in error log each time.

error PHP Warning:  Cannot modify header information - headers already sent by (output started at /home/account/public_html/shop/includes/classes/captcha.php:276) 
in /home/account/public_html/shop/includes/classes/captcha.php on line 152

The line numbers above refer to the following header code in function showCaptchaImg() within /includes/classes/captcha.php

		header('HTTP/1.0 200 OK');
		header('Last-Modified: ' . gmdate('D, d M Y H:i:s') . ' GMT');
		header('Expires: Thu, 19 Nov 1981 08:52:00 GMT');
		header('Cache-Control: no-store, no-cache, must-revalidate');
		header('Pragma: no-cache');
		header('Content-Type: image/' . $this->img_type);
		header('Content-Length: ' . strlen($this->img));

This is for the shop on PHP 4.4.4.

I'm suspecting this is related to error I reported in shop running PHP 5.16

Recommends anyone? Thanks.

It's normal for this recommendations.

It's normal for this recommendations.

OK. So you're stating that by implementing the edits as I did, that is the casue of the error log entries.

OK. But if I did not make the recommended edits the mod does not work for me.

So it is a Catch-22.

As babygekko recommended I commented out in /classes/captcha_img.php

1. the if (function_exists('glob') structure
2. ob_start() and ob_end_clean()

Is there a suggested method to make the mod work WITHOUT the error log entries?

I will provide access credentials to view if you wish to check out.
