Open Script Solution

In osTicket System version 1.6 RC5, there is no CAPTCHA feature on the open new ticket form. This will cause sometimes you will receive the ticket that contains of spam, and this will bother your ticket system. In order to decrease the spam ticket, you can implement the security code (CAPTCHA) feature as you can see from this URL: http://www.white-hat-web-design.co.uk/articles/php-captcha.php on your osTicket form. Please try the following steps.

1. Download the file from this URL: http://www.white-hat-web-design.co.uk/articles/captcha.zip.
2. Extract the .zip file above, then upload two files: CaptchaSecurityImages.php and monofont.ttf into the main or root directory of your osTicket.
3. Open include\class.ticket.php file, and find this code:

           if(strcasecmp($origin,'web')==0) { //Help topic only applicable on web tickets.
               $fields['topicId']  = array('type'=>'int',      'required'=>1, 'error'=>'Select help topic');

   after that code, add the following code:

               // Begin of MOD CAPTCHA, added by Masino Sinaga, July 17, 2009
               $fields['security_code']  = array('type'=>'code',     'required'=>1, 'error'=>'Please type correct CAPTCHA code');
               // End of MOD CAPTCHA, added by Masino Sinaga, July 17, 2009

4. Open \include\class.validator.php file, and find this code:

               case 'text':
               case 'string':
                   break;

   before that code above, please add the following code:

               // Begin of MOD CAPTCHA, added by Masino Sinaga, July 17, 2009
               case 'code':
                   if( $_SESSION['security_code'] != $_POST['security_code'])
                   $this->errors[$k]=$field['error'];
                   break;             
               // End of MOD CAPTCHA, added by Masino Sinaga, July 17, 2009

5. Open \include\client\open.inc.php file, and find this code:

   if(!defined('OSTCLIENTINC')) die('Kwaheri rafiki!'); //Say bye to our friend..

   after that code above, please add the following code:

   // Begin of CAPTCHA feature, added by Masino Sinaga, July 17, 2009
   session_start();
   // End of CAPTCHA feature, added by Masino Sinaga, July 17, 2009

   find also this code:

       <tr>
           <th><?php echo (I_C_OPEN_ATTACHMENT) ?></th>
           <td>
               <input type="file" name="attachment"><font class="error">&nbsp;<?php echo $errors['attachment']?></font>
           </td>
       </tr>
       <?php }?>

   then after that code above, please add this following code:

   <!-- Begin of CAPTCHA feature, added by Masino Sinaga, July 17, 2009 -->
       <tr>
           <th><?php echo (I_C_OPEN_SECURITY_CODE); ?></th>
           <td valign="middle">
               <img src="CaptchaSecurityImages.php?width=100&height=38&characters=6"/>
               <input id="security_code" name="security_code" type="text" size="15"><font class="error">&nbsp;*&nbsp;<?=$errors['security_code']?></font>
           </td>
       </tr>
   <!-- End of CAPTCHA feature, added by Masino Sinaga, July 17, 2009 -->

Please note, in some part of the code above, you will find constant(s), and the other side, you will also find the sentence that has not been converted to its constant. This happened because some of the code have not been translated to the language file. Please adjust them with your need. Thank you for your understanding.
