I have a highly modified PHP script supporting my contact form. The script has been expanded to prevent certain comments on the form, includes CAPTCHA, and required field filtering. The PHP form submission script was initially developed by the now defunct company, Allibsus Mail Pro PHP. It allowed a person to upload file attachments with the form submission. In the course of adding functions to the script, the scripts ability was corrupted by a past ScriptLance developer, not allowing it to upload files. This is the purpose of this project. To locate a skilled PHP developer who can wade through a series of add-ons to discover why this function is corrupt, fix it while not corrupting the add-ons. I have been through my share or amateurs on ScriptLance, so please, this is only for the skilled who have extensive experience. Please no slackers, only those who take time to thoroughly read my detailed instructions. Also, while at it, would like to add a phone verification that checks North American phone numbers 000-000-0000 and echoes any errors in the same location as the other errors echo. But implement the full regex expression I will provide that covers 14 typed variables. I will provide the PHP code, you just need to make it work. The form is found at http://www.mccormackprinting.com/quote.php, but please don't test it. This is for a client and they will not appreciate a rash of form submissions from gandering developers. You will not be able to learn anything by testing it anyway.
