CiviCRM Community Forums (archive)

I was wondering if it would work to add a custom field to the create and edit forms for Events using the buildForm hook, and then using the postProcess hook to handle the information that the custom field passes as part of the form. If it can be done, how would the hook be used to add the field, and would I need to edit the template files for the form. My goal is to make changes only using the modules so that my clients base installation of civiCRM remains un-altered as once this project is over, I will not be continuing to support it. Thanks again for all the help here in the forums, you guys are great
