Could we change the submit process?
Now it calls $function($form, $form_state);
It will be better if we use call_user_func that is used in another places. It will allow us to hide the form processing logic into classes like this:
<?php
class form {
function _($form_state) {
}
function __submit($form, &$form_state) {
}
}
?>We will register it in this way.
<?php
'page callback'=> 'drupal_get_form',
'page arguments'=> array('form::_', 3),
?>It is for en example.
Now it builds the form by this way, but it can not process it
