Enjoy!

p/s : next for the extending this demo on validation on scenarios, custom validation, redirect to the action on controller with parameter, ...

Validation with custom validation on Model, redirect to the action on controller with parameter after submit

Expand Fun Model class
- try others valiatotion http://www.yiiframework.com/wiki/56/ref ... validation
- build custom validation
- hasErros() to check has error
- addError vs addErrors

Code: Select all

class FunModel extends CFormModel
{
    public $name;
    public $age;
    public $favor_food;

    /**
     * Declares the validation rules.
     */
    public function rules()
    {
        return array(
            array('name, age', 'FunValidation', 'on'=>'scenario'),
            array('favor_food', 'in',
                'range' => array(0,2,3,4,5),
                'message' => 'Life is not only eat to live ! So flatter ?!<br><i>Try your select again.</i>'),
        );
    }

    public function FunValidation($attribute,$param)
    {
        if (!$this->hasErrors()) { /* if form has error, this will skip*/
            if (empty(trim($this->name)) && empty(trim($this->age))) {
                //$this->addErrors(array('name'=>'','age'=>'Plz input Name and Age!'));
                $this->addErrors(array('Plz input Name and Age!')); /* Set message error on summary */
                $this->addErrors(array('age'=>'','name'=>'')); /* Set error on control attribute */
            }
            else if (empty(trim($this->name)) || empty(trim($this->age))) {
                if (empty(trim($this->name)))
                    $this->addError('name', 'Plz input Name!');
                else if (empty(trim($this->age)))
                    $this->addError('age', 'Plz input Age!');
            }
        }
    }
}

Expand Examples Controller
- Apply Validation of Model on scenarios
- important : $model->attributes= $_POST['FunModel'];
- redirect(array('control/action' , 'paramter_name_1' => value_1, 'paramter_name_2' => value_2, [n_parameter=n_value])
- $model->validate() vs $model->validate('scenarios')

Code: Select all

class ExamplesController extends Controller
{
    public function actions()
    {
        return array(
            'do' => 'application.controllers.Read.DoAction',
            'previous' => 'application.controllers.Read.PreviousAction',
            'next' => 'application.controllers.Read.NextAction',
            'find' => 'application.controllers.Read.FindAction',
            'test' => 'application.controllers.Read.TestAction',
        );
    }

    public function actionIndex()
    {
        echo "Submit Sucess!";
    }

    public function actionFunValidForm()
    {
        $model = new FunModel;

        if (isset($_POST['FunModel']))
        {
            //$model->attributes= $_POST['FunModel'];

            /*Validation on scenario*/
            $model->setScenario('scenario');

            /* Put attributes after scenraio before validate */
            $model->attributes= $_POST['FunModel'];

            if ($model->validate('scenario') && $model->validate()) {
                $this->redirect(array('/examples/index','name'=>$model->name,'age'=>$model->age));
            }
            else
