I need to customize delete action of user list and using this :
$crud->callback_delete(array($this,'user_delete'));
public function user_delete($primary_key)
{
$this->user_model->_admin_delete_user($primary_key);
}
However, my custom delete function run pretty slow, so I need to add a loading view, or "deleting" message while it's running.
How can I do that?
Thanks a lot.
And sorry if my english is terrible...
