Ok, suppose i have two employee id (1 and 2),

now if i select 2 , the field1 and field2 will be required, but not for 1. To do this, follow the code below,

In your model:




public function rules() {

        return array(

            array('field1, field2', 'required','on'=>'rq'),

            array('field1, field2', 'safe', 'on' => 'search'),

        );

    }

In your controller:




 public function actionCreate() {

        $model = new Users;

        $this->performAjaxValidation($model);

        if (isset($_POST['Users'])) {

            $model->attributes = $_POST['Users'];

          $model->scenario = $model->employee_id=='2' ? 'rq':'';

            if ($model->save())

                $this->redirect(array('view', 'id' => $model->id));

        }

        $this->render('create', array(

            'model' => $model,

        ));

    }

In your view/_form.php:





<?php echo $form->labelEx($model, 'field1'); ?>

<?php echo $form->textField($model, 'field1', array('size' => 60, 'maxlength' => 255)); ?>

<?php echo $form->error($model, 'field1'); ?>


<?php echo $form->labelEx($model, 'field2'); ?>

<?php echo $form->passwordField($model, 'field2', array('size' => 60, 'maxlength' => 255)); ?>

<?php echo $form->error($model, 'field2'); ?>   


<?php echo $form->labelEx($model, 'employee_id'); ?>

<?php 

echo $form->dropDownList($model, 'employee_id', CHtml::listData(Employee::model()->findAll(), 'id', 'name'), array(

                            'prompt' => 'Select One',

                        ));

?>

<?php echo $form->error($model, 'employee_id'); ?>

Thanks this is working but I have 2 scenarios




$model->scenario = $model->employee_id=='2' ? 'rq':'';

$model->scenario = $model->employee2_id=='2' ? 'rq2':'';

The scenario is being assigned to the last one that is rq2 it is not taking rq

Did you tried this?




public function rules() {

        return array(

            array('field1', 'required','on'=>'rq'),    

            array('field2', 'required','on'=>'rq2'),             array('field1, field2', 'safe', 'on' => 'search'),

        );

    }







public function actionCreate() {

        $model = new Users;

        $this->performAjaxValidation($model);

        if (isset($_POST['Users'])) {

            $model->attributes = $_POST['Users'];

          $model->scenario = $model->employee_id=='1' ? 'rq':'';

          $model->scenario = $model->employee_id=='2' ? 'rq2':'';

             if ($model->save())

                $this->redirect(array('view', 'id' => $model->id));

        }

        $this->render('create', array(

            'model' => $model,

        ));

    }
