Same name and namespace in other branches

1. 7 webform_protected_downloads.module \webform_protected_downloads_form_alter()

Implementation of hook_form_alter(). Doc says that $form_state is passed by reference, but that generates warnings: warning: Parameter 2 to webform_protected_downloads_form_alter() expected to be a reference, value given in /includes/common.inc on line 2883. Since we don't use that parameter here, we can safely set it to value instead of reference.

Parameters

array $form :

array $form_state :

string $form_id :

Return value

void
