Took me a day or two to make something work but this is what I have:
To see it in action: http://www.mediasponder.biz/x/t.php/2 (((( PLEASE BACK UP YOUR CURRENT FILES FIRST )))) In the skins directory open 'mainregisterusernopass.htm' and add this code to the top; Code:
<script language='JavaScript' type='text/javascript'> function refreshCaptcha() { var img = document.images['captchaimg']; img.src = img.src.substring(0,img.src.lastIndexOf("?"))+"?rand="+Math.random()*1000; } </script> PS: that smiley that jumped into the code box is supposed to be a second closed parenthesis ) Then just above the input submit button code, add this; Code:
<p> <img src="captcha_code_file.php?rand=<?php echo rand(); ?>" id='captchaimg' ><br> <label for='message'>Enter the code above here :</label><br> <input id="6_letters_code" name="6_letters_code" type="text"><br> <small>Can't read the image? click <a href='javascript: refreshCaptcha();'>here</a> to refresh</small> </p> <input class=inputbutton type=submit name=register value="Register"> Save this and be prepared to upload it back into your skin directory. Now open up the 'register.php' file and add the following code at the top just after the <?php; Code:
session_start(); // start up your PHP session! // Function to validate against any email injection attempts function IsInjected($str) { $injections = array('(\n+)', '(\r+)', '(\t+)', '(%0A+)', '(%0D+)', '(%08+)', '(%09+)' ); $inject = join('|', $injections); $inject = "/$inject/i"; if(preg_match($inject,$str)) { return true; } else { return false; } } #-------------------------------------------------------------# Find Code:
if (isset($_POST['register'])) { and place the following code just after the '{' symbol like this; Code:
if(IsInjected($useremail)) { $errormessage = get_error($lang['invalid_email']); } if(empty($_SESSION['6_letters_code'] ) || strcasecmp($_SESSION['6_letters_code'], $_POST['6_letters_code']) != 0) { //Note: the captcha code is compared case insensitively. //if you want case sensitive match, update the check above to // strcmp() $errormessage = get_error($lang['captcha']); } Save that and be prepared to re-upload it. Open up the eng.php file located in the lang directory and add the following line anywhere in the top half of the page; Code:
'captcha' => 'wrong captcha answer try again', Save that and be prepared to re-upload it. Now before you upload those modified files above, download unzip and upload this package. http://www.mediasponder.biz/x/t.php/1 Now you can upload all the new and modified files. post here if there are problems. I kinda got excited and posted this fast because I wanted to share this with you guys. My site is new and I haven't done the domain name for it yet. |
