CiviCRM Community Forums (archive)

We are working on a pretty awesome implementation of CiviCRM for a nonprofit organization that runs some pretty sophisticated online fundraising campaigns, and have tried to make a modification to the Thank You page to allow for either the creation of a standard CiviCRM thank you or redirect to a different page. For some reason the code we are using is not redirecting to the URL entered when we are doing testing.

I wanted to get some recommendations on ways we can implement this code. It seems like the system forces a person to a thank you page after confirmation of a contribution. Can you recommend where we look for the code that does this?

I created a page in the wiki here: http://wiki.civicrm.org/confluence/pages/createpage.action?spaceKey=CRMDOC&fromPageId=15402171

We are using a hook to implement this, which may be the issue. The code is here:

   1.
      <?php
   2.
      // $Id$
   3.
       
   4.
      /**
   5.
       * @file
   6.
       * Adds custom CiviCRM functionality to JGI.  This changes the Thank You settings form
   7.
       * for Contribution pages and adds an input for a redirect URL and stores in in the DB.
   8.
       * Then when a user goes through the contribution page and confirm their donation, they
   9.
       * are redirected to that URL instead of seeing the Thank You page.
  10.
