Drupal Studs help me with my form_alter hook ( I am almost there)

Answer 1

I suggest you have a look at content profile module before rolling your own solution.

You define your a custom content type (node) for your school registration, add in you cck fields, and activate it as a content profile. On content profile settings, you then activate it on user registration form. Zero code !

Answer 2

RedBen is right, content profile may be a better solution.

It seems like you're adding the second submit handler in a strange way - it's simply the name of a function, not an array. Have you checked that your submit handler is running?

Because the reference to the handler is a simple string, you just need to append it to the array using

$form['#submit'][] = '_module_registration_submit'

If you need it to run before the standard handler, use array_unshift to push it onto the beginning of the #submit array.
