| For doing this CAPTCHA I would suggest using a session variable where you store the string generated and displayed on that dynamically generated image. can you explain this instruction in detail? what is a session variable? store the string? where do i get the dynamically generated image? the referenced website (http://www.site.com/captcha.php) didn't work... thank you! |

| This code works great, but one thing i would like it to do if anyone can tell me how to do this, i would like the error message to display next to the verification box instead of at the top of the page , is that possible? Thanks, Elaine ----------------- Veselin: you need to have your form on PHP based web page and the verification to be on top of it and then print the error message where your box is. For a small fee we can make your contact form on PHP page and also make the message display next to the captcha box. Email us if you are interested. |

| I would like to use the Captcha.php validation script for one of my forms. The form is here: http://www.****.com/info-form.html How much will you charge to do this for me and send me the completed revised form by email attachment? I would like it to show up very much the way that THIS form does. Thanks, Hugh ------------------- can you send me a message that you receive when the form is submitted. It usually costs about $35 to add a captcha script and make the form on PHP page. Veselin |

| For igor (about session_start() [function.session-start]: error) @session_start(); if (!preg_match("/^[0-9a-z]*$/i", session_id())) { $error->handleError("WARN", "your ssid is expired"); session_regenerate_id(); } // just try it. |
