*
*
* IMPORTANT – PLEASE READ:
* 1. YOU MUST UNCOMMENT THE CODE FOR IT TO WORK.
* – This means removing the ‚//‘ in front of each line.
* – If you do not know what php comments are see here: http://php.net/manual/en/language.basic-syntax.comments.php
*
* 2. YOU CAN ENTER ANY EMAIL ADDRESS IN THE $from VARIABLE.
* – This is the address that will show in the From column in your mail application.
* – If your form contains an email field, and you want to use that value as the $from variable, you can set $from = $this->fields[’name of your email field‘];
*
* 3. FILE ATTACHMENTS
* – As stated in the description on codecanyon, this code does not mail attachments. Google ‚php html email attachments‘ for information on how to do this
*
* 4. REDIRECTING TO ANOTHER PAGE AFTER SUBMISSION
* – This is an ajax enabled form, so you need to perform the redirection in main.js AND this php file.
* a. Please see instructions in main.js for redirection. This is for users without JS.
* b. Replace the relevant code below with the page you would like to redirect to. REMEMBER TO UNCOMMENT THE LINE FOR IT TO WORK.
