On submit, check if there is data to create the node

On my user register form I have a checkbox that let's the user choose if he wants to have a content type for his profile.
So if he does not check that checkbox I don't want to create a node of that content type for his profile.

The solution i came up with is:
I have a validation function that checks if that checkbox is checked, and if not, i unset the data for that node.
<?php unset($form_state['content_profile_registration']['optional_content_type']['node']); ?>

But the submit function of the content_profile_registration module tries to save the node of that content type despite the fact that there is no data resulting in some warnings...

So i just added an if clause that checks if there is data for that content type, and ignore ot if there is none.

<?php
function content_profile_registration_user_register_submit($form, &$form_state) {
  foreach (content_profile_get_types('names', 'registration_use') as $type => $typename) { 
    if($node = &$form_state['content_profile_registration'][$type]['node']) {
      // Set user's information for the node.
      ...........
      // Create the node.
      ...........
    }
  }
}
?>

This is a minor, unintrusive change that, in my oppinion, could be usefull. If the maintainers of this module agree, this patch could be merged into HEAD
