使用PHP启动联系表单。 无法让它工作[关闭]

So I have designed a contact form for my webpage so that users can email me directly from the webpage. I have the html in contact.html and the PHP code in contactForm.php if the user succesfully inputs his/hers information and the email is sent I want the user to be redirected to thanks.html. I have tried to test it out but it just wont work. Where do i put my php file? Do I have to change anything on cPanel or GoDaddy? The code is below...

contactForm.php

contact.html

Here is a link to a php form script I rewrote for you: http://pastebin.com/w14MSrcL

Replace your contactForm.php codes with this and you're good to go.

Keep this file in the same directory where your html file is in.
