CiviCRM Community Forums (archive)

I'm working on a project described here:

http://forum.civicrm.org/index.php/topic,18837.msg78256.html#msg78256

Essentially it's a drupal module that implements buildForm(), validate() and postProcess() hooks that include classes/functions from another (non-drupal / non-CMS) PHP program.

A few hook questions have come up while I'm working:

1) If my validate() hook returns errors, does the custom buildForm() hook get called again when rebuilding the form with the errored fields highlighted?

2) Is there an easy way to get a participant count from a submitted price set?  I want to check the partipant count against some other fields in my validate().

3) What's the right way to handle an error that arises in my custom postProcess()?  postProcess() return val isn't checked it looks like.

I'm sure there will be more...

Thanks Lobo.

Another question -- is it possible to have a module include an .extra.tpl ?
