hi, I have 2 callbacks , one used for unsetting a password verification field, the other encripts a password, but only the latest one execute, even if a change the callbacks order.

function display_grid(){



$this->load->library('form_validation');

$data['titulo'] = "Tabla de elementos";

$data['contenido'] = 'cms_elementos_grid';

$crud = new grocery_CRUD();

$crud->set_subject('usuario');

$crud->set_table('usuarios');

$crud ->columns('id', 'email', 'tipo', 'estado', 'creado_en');

$crud ->fields('email', 'clave', 'vclave','tipo', 'estado');



$crud->display_as('vclave', 'Verificar Clave');

$crud->change_field_type('clave', 'password');

$crud->change_field_type('vclave', 'password');

$crud->required_fields('email', 'clave','vclave', 'tipo');



$crud->set_rules('email', 'Correo Electronico', 'valid_email|callback_username_check');  <---- at updating throws email already exists message as declared on callback ..

$crud->set_rules('clave', 'Clave', 'required|trim|max_length[20]');

$crud->set_rules('vclave', 'Verificar Clave', 'required|trim|matches[clave]|max_length[20]');





$crud->callback_before_insert(array($this,'unset_vclave'));



$crud->callback_before_insert(array($this,'encriptar_clave')); <-----THIS ONE RUN



$output = $crud->render();

$data['tablecrud'] = $output;

$this->load->view('cms_plantilla',$data);



}





 function username_check($str)

  {



   $num_row = $this->db->where('email', $str)->get('usuarios')->num_rows();



   if($num_row > 0)

   {

     $this->form_validation->set_message('username_check', 'El email ya existe en el sistema');

     return FALSE;

   }

   else

   {

     return TRUE;

   }

 }   







function unset_vclave($post_array){



unset($post_array['vclave']);

return $post_array;

}



function encriptar_clave($post_array){



$post_array['clave'] = substr(do_hash($post_array['clave']),0,16);

//print_r($post_array);

return $post_array;

}

Hi! I don't understand why you need two callback function ?

[amipax]

hi victor, I used two callback functions to have a proper name for every process in execution (ex. unset_password, encript_password) , but as you mention it, I could have used one and it actually works using one callback (problem solved), is there any reason why it doesn't work with 2 callbacks ?

Spasibo /thanks

[victor]

the answer is simple: it is possible to use only once this function

Ok,

[amipax]

I have a new problem at set_rules('email', ' callback_check_username') when trying to "update" status of a user , it throws a email already exist message, i tried to bypass it when editing using $crud->getState == edit but I couldn't make it work. i keep getting the message declared on the callback.

	    if($crud->getState()=='edit')

	    { 

               if($this->input->post('email'))

                {

                    $user_data = $this->db->get_where('your_users_table',array('your_user_id_field'=>$this->input->post('yuur_user_id_field')))->row_array();

                    if($user_data['email']!=$this->input->post('email'))

                    {

						 $crud->set_rules('email', 'Email', 'required|valid_email|is_unique[contacts.email]');

                     }

                }

	    }

	    else

	    {

			    $crud->set_rules('email', 'Email', 'required|valid_email|is_unique[contacts.email]');

		 }
