I want to deal with special fields in the model In the model code:

    public function datagrid($industries = array()){
        $data = $this->get();
        foreach ($data as &$value) {
            $_industries = array();
            $_temp = explode(',', $value->industries);//The database field values:1,2,3
            foreach ($_temp as $val) {
                if(isset($industries[$val])){
                    $_industries[] =   $industries[$val];
                }
            }
            $value->industries = $_industries;//After processing the value of the:array('餐饮','酒店','其他');
        }
        return $data;
    }

In the controller code:

$industries = array(array('id'=>1, 'name'=>'餐饮'), array('id'=>2, 'name'=>'酒店'), array('id'=>3, 'name'=>'其他', ));
$adsense = new Adsense();
$data = $adsense->datagrid($industries)
$dg->setSource($data);
