Please tell me which file is responsible for processing form? (File handler)

Hello,

Please tell me which file is responsible for processing form? (File handler)
what a way into it?

I need to add to the file handler that is - $fefers = $_POST['fefers'];


But I can't.

Help please,
Thank you very much

CRF - Version 4.0 RC3.5.2
Joomla 2.5

Then ? what would you like to do with this new variable ? why can't you simply use the POST var directly ?

Max

sorry for the copy
I badly understand English.
I just need the path to the file handler and paste as this thing.

This is for referral links

The line of code you have will not have any effects on any stuff outside the file, so you may be even on the wrong direction, please let us know what you need to do and we will try to help!
