Get value of table in Edit Form

Hello,

I have view: as shown at capture view.

Then i click Edit as shown at capture.

I Have question :

how i can use the information Jenis Unit become where condition in my code.

public function ChooseOperator()

{

$comp = "1";

$crud = new grocery_CRUD();

$crud->set_theme('datatables');

$crud->set_table('projectunit');

$crud->set_relation_n_n('unitsc', 'projectunitselec', 'unit', 'idprojectunit', 'idunit', 'unitcode','priority',array('unit.sertifikatid' => $comp ));

//$crud->unset_columns('priority');

//$crud->add_action('Detail Unit', '', 'rmi/ChooseOperator/read','ui-icon-plus');

$crud->set_relation('proid','project','proname');

//$crud->set_relation('sertifikatid','sertifikat','sertifikatname');

$crud->fields('proid','sertifikatid','unitsc');

$crud->add_action('Detail Unit', '', 'rmi/ChooseOperator/edit','ui-icon-plus');

$crud->display_as('proid','Project Name');

$crud->display_as('sertifikatid','Jenis Unit');

$crud->display_as('unitsc','Unit Dipakai');

// $crud->fields('proname');

// $crud->display_as('proname','Nama Project');

// $crud->order_by('proname','asc');

// $crud->field_type('proid', 'hidden', $proid);

// /$crud->callback_column('proname',array($this,'_callback_webpage_url'));

$output = $crud->render();

$this->_rmi_output($output);

// print($proid);

// print_r($output);

}

So i want value of $comp become a jenis Unit, why i need because i want only show specific information for set_relation.

really need a help ...
