Hi, I have this model:

 

[attachment=584:sample_cars.png]

 

I'm working with a CRUD on CARCODES table... and I would like to show DESCRIPTION (from Brands table) + NAME (from Cars table) replacing the ID_CAR field ... (set_relation, but taking the descriptions from 2 tables) ...

 

Is that possible?

 

So, I have the "carcodes" CRUD.... And I want something like this (replace the ID_FIELD With BRAND and CAR only to show)

At least from my point of view the easiest way is to make you own simple model (not by extending the GC model, just a new one!).

Probably the best way to do it is,

 

(sample code, file itemmodel.php under application/models)

 

<?php
class itemmodel extends CI_Model {
    
    function __construct()
    {
        parent::__construct();
        $this->load->database();
    }
public function get_healing_techniques_id_description()

{
$query = "SELECT `id`, `description` FROM `groups` WHERE `activities_id` IN (SELECT `id` FROM (`activities`) WHERE  `description`  LIKE 'H-%' ORDER BY `id`)";
$result = $this->db->query($query);
return $result;
}

//... }

 

and then on your controller,

$this->load->model('itemmodel');
		
		// multiple healing techniques
		$healings = $this->itemmodel->get_healing_techniques_id_description();
		foreach ($healings->result() as $row)
		{
			$myarray2[$row->id] .= $row->description;
		}
		$this->grocery_crud->field_type('healing_techniques_ids','multiselect', $myarray2);
