CiviCRM Community Forums (archive)

Hi,

I've looked at the hook documentation but to understand it better and what hooks are available require more experimentation with the code on my part and hopefully someone has already done this and can provide some guidance as I'm just starting to learn Drupal/CiviCRM. 

I'm trying to change the Profile such that instead of having just Save and Cancel functionality, I need a Finish and Save functionality.  Our profile is being used as an application and takes some time to fill out so I want to provide the users an ability to come back to the Profile.  The Finish button would check that certain fields are required and if everything is filled out properly, send an email to us to go on and review the application. 

My basic questions are:
1. What file do I need to edit/create to put in the hook_civicrm_post() function to have it process the form from the profile?
2. I've setup the Profile to not have any required fields and will instead be checking required fields manually in the post hook.  If I return a false to hook_civicrm_post can I alert the user with the proper error messages on the Profile form?

Any help is greatly appreciated.

Thanks,
