Created by: Dollars5 and Vinoth Kannan
Created on: 2007/02/27

Description
Improves the captcha that comes with the Plig framework to have alpha-numeric confirmation and including your own fonts for better protection.

Upload the better_captcha_fonts to Pligg root directory, replace the /libs/ts.php with the one provided with this release.

This module is inspired and based on the Better Captcha for PhpBB2 http://www.phpbb.com/phpBB/viewtopic.php?t=473222 by paul999



Revision History
v0.1 2007/02/27 Dollars5 - First version

Notes:
Should you replace with your own fonts - just name in sequence and place the fint inside the better_captcha_fonts folder.

Should you think of providing more protection against spam, replace the $pattern = "O123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ"; with a different pattern and make sure to adjust the numbers - we use 36 elements in this string. And to provide better difference between O (oh) and 0 (zero) - we have replaced 0 with O.

Should you make any modifications - please do notify in here or improve on it further.

Regards,
Dollars5.

Should you think of using these captchas for story submission process too, please use the following code - this is a temporary solution and needs Admins/lead Devs suggestions to make it better.

A temporary solution would be is to do the following modifications:
1] open submit_empty_submit_form.tpl before

<input type="text" name="url" id="url" value="http://" size=55 class="form-full" />

add the following lines

<input type="hidden" name="ts_random" value="{$submit_rand}" /><br />
		<img src="{$my_pligg_base}/ts_image.php?ts_random={$submit_rand}" class="ch2" />
		<p><input type="text" size="20" name="ts_code" /><br /><br />

2] Open submit.php, in function do_submit1(); before

if($url == "http://" || $url == ""){
		if(Submit_Require_A_URL == false){$linkres->valid = true;}else{$linkres->valid = false;}
	}

add

if (!ts_is_human()) {
		$main_smarty->assign('register_error_text', "badcode");
		$main_smarty->display($the_template . '/register_error.tpl');
		return;
	}

This uses the same register_error.tpl files - should need another type of display, edit or forward accordingly.

I got it .. not sure what happened.

Has anyone tested it on the story submission process? I am getting a ton of story spam.
