Form Generation Library

[eluser]dinhtrung[/eluser]
Tonight I played with widget_pi, Modular Separation and Form Generation, and found out the fact that only one the lastest model added is run if the form is valid. Please support multiple calls for methods and postprocess methods. An use case could be like this:
I create a form for admin to add a new user into the system. The user must be assign a profile data in another table, and I don't want to mix the basic info and profile info for an user in only one table. So I create User_profile widgets, to handle profile data and Users controller to handle basic information.

Code:

/* File : modules/users/controllers/users.php */
   ....
   function create()
   {
      $this->form->open()
           ->text('username', "Username")
           ->password('password', "Password");
      widget::run('profile/profilebox');
      $this->form->model('user_m', 'fcreate')
           ->onsuccess('redirect', $this->uri->uri_string());
   }
   ...
/* File : modules/profile/widgets/profilebox.php */
   class Profilebox extends Widget{
      function run(){
          $this->form->text('fullname', "Fullname", 'required|trim|max_length[30]')
               ->textarea('signature', "Signature", 'trim|max_length[255]')
               ->text('phonenumber', "Phone Number", 'trim|exact_length[10]')
               ->model('profile/profile_m', 'addinfo', array('userid' => $this->uri->segment(4, FALSE)));
      }
   }
/* File : modules/profile/models/profile_m.php */
   ...
   function addinfo(&$form, $data){
      if ($data['userid']) $this->update_profile_data($data['userid']);
      else $this->add_profile_data($data);
   }
   ...

Because I don't use English for most of my projects, please consider adding $label = $this->CI->lang->line($label) for Form elements. I usually extends CI native language library to return the original string if the replace string is not found. So, if $lang['form_label'] is undefined, lang('form_label') will return form_label.
Back to the multiple models issue, here is my modification:
