curl login script

I have created a login script for a website using curl, until a few weeks ago the script was working fine, but since the login system of the site uses an auth code I have not been able to login. using curl you will need to be able to submit the correct auth code to the site, this is something I don't know how to do. This job should not take more than an hour so bid accordingly and I am not interested in waiting 7 days for a simple solution. I will give you the code that I have now and you probably may just have to add 1 or 2 lines. Please only bid on this project if you understand what to do. Requirements - The code must work on a linux apache server Note the auth code for the login system can be found on the source code of the url simply by searching csrf
