验证Yii中的动态文件字段失败

嗨，我正在尝试验证在Yii中创建的活动filefield字段的动态性

我使用forech来构建这些输入，问题是，当试图验证用户何时选择图像时，请指出您选择的文件是否超过了允许的重量，以及它是否是正确的文件格式。

但我不知道我做错了。

我试过这个：我的型号

public $image;
public function tableName() {
    return 'vrf_image';
}
/**
 * @return array validation rules for model attributes.
 */
public function rules() {
    // NOTE: you should only define rules for those attributes that
    // will receive user inputs.
    return array(
        array('id_form', 'numerical', 'integerOnly'=>true),
        // Pruebas para subir imagen
            // Inicio
            array(
                'image',
                'file',
                'types'=>'jpg, gif, png',
                'allowEmpty'=>true,
                'on'=>'update',
                'on'=>'insert',
                'wrongType'=>'Solo imagenes',
                'mimeTypes' => 'image/gif, image/jpeg, image/png',
                'wrongMimeType' => 'Invalid mime type',
                'maxSize'=>1024*1024*2,
                'tooLarge'=>'File has to be smaller than 2MB',
            ),
            array(
                'image',
                'length',
                'max'=>50,
                'on'=>'insert,update'
            ),
            array(
                'id, image, id_form, id_ques',
                'safe',
                'on'=>'search'
            ),
        // Fin
    );
}

我的观点

<div class="container-fluid">

在我的控制器中

public function actionCreateImage($id) {
    $form = VrfForm::model()->find("id_user = $id");
    $path_picture = realpath(Yii::app()->getBasePath()."/../VerificationResource/images")."/"; //ruta final de la imagen
    if(isset($_POST['VrfImage'])) {
        foreach ($_POST['VrfImage'] as $key => $value) {
            $modImage = new VrfImage;
            $modImage->attributes = $value;
            //print_r($modImage->validate());
            if($modImage->validate()){
                echo 'Correcto';
                ////////////////////////////////////////////////////////////////////
                $rnd = rand(0,9999);  // generar números aleatorios entre 0-9999
                $uploadedFile=CUploadedFile::getInstance($modImage,'['.$key.']image');
                $fileName = "{$rnd}-{$uploadedFile}";  // número aleatorio + nombre de archivo, o se puede usar: $fileName=$uploadedFile->getName();
                if(!empty($uploadedFile)) { // Compruebe si el archivo se ha subido o no.
                    $uploadedFile->saveAs($path_picture.$fileName);
                    $modImage->image = $fileName;
                    $modImage->id_ques = $value['id_ques'];
                    $modImage->id_form = $form->id;
                    if($modImage->save()) {
                        //echo ' REVISA!!! <br>';
                    }
                    else{
                        echo $modImage->error();
                    }
                }
                ////////////////////////////////////////////////////////////////////
            }
            else{
                echo 'Falla';
                //$this->redirect($this->createUrl('default/Form'));
            }
        }
    }
    //$this->redirect(Yii::app()->user->returnUrl.'backendVerification/default/Form?id='.$id);
}

但别这样。它不起作用

表单中的"clientOptions"不好吗我在模型中的规则不好吗
