Dynamic callback_field

just i share this solutiÃ³n to create dynamic callback_field, i used just callback_field but i think works to other callbacks

with this solution, you can use the same function to all field you want

pd: sorry for my english

function somefunction(){
$crud = new Grocery_CRUD();
$crud->set_table('some_table');
/*...*/

$crud->callback_field('some_field', array($this,'callback_selectImage'));//normal call
$crud->callback_field('some_other_field', array($this,'callback_selectImage')); //normal call

/*...*/ $this->salida($output); }

/**

* $callback =

* stdClass Object

* (

* [name] => some_field

* [type] => int

* [max_length] => 11

* [default] => 7

* [primary_key] => 0

* [db_max_length] => 11

* [db_type] => int

* [db_null] =>

* [db_extra] =>

* [required] =>

* [display_as] => Imagen de fondo del contenedor

* [crud_type] => relation

* [extras] => Array

* (

* [0] => qb_contain_bg_image_id

* [1] => gm_imgs

* [2] => image_name

* [3] =>

* [4] =>

* )

* @param type $value

* @param type $primary_key

* @param type $callback

* @return string

public function callback_selectImage($value="", $primary_key = null, $callback) { $img = new Images_model(); //object to table images $res = $img->get_all_img_buttons(); //get all images $out = '<select class="form-control select2 sel_image" id="field-'.$callback->name.'" name="'.$callback->name.'" placeholder="Seleccionar Tipo" >'; $out .= '<option value="" selected disabled>Seleccionar</option>'; foreach($res as $key=>$val): if($value == $val->image_id): $out .= '<option value="'.$val->image_id.'" title="'.base_url().'assets/uploads/imgs/'.$val->image_url.'" selected>'.$val->image_name.'</option>'; else: $out .= '<option value="'.$val->image_id.'" title="'.base_url().'assets/uploads/imgs/'.$val->image_url.'">'.$val->image_name.'</option>'; endif; endforeach; $out .= '</select>'; return $out; }
