Yii2框架：调用未定义的函数app \ controllers \ VisitorForm

Question

I am working in Yii2 Framework. In my model, I have class

class VisitorForm extends Model
{
    public $station;
    public $center;

    public function rules()
    {
        return [
            [['station', 'center'], 'required'],
            ];
    }
}

and in my SiteController class I have the action method

 public function actionVisitor()
    {

        $model = VisitorForm();
        if($model->load(yii::$app->request->get())){
            return $this->render('visitor', ['model' => $model]);
        }
    }

Also, I have included use app\models\VisitorForm;. Also in my view directory I have visitor.php.

The above code is exactly similar to the EntryForm code give in Yii2 Definitive Guide.

But I am getting the error while executing the code at line

$model = VistorForm(); // throwing error at this line


Call to undefined function app\controllers\VisitorForm()

I am not able to figure out, what is going wrong with me. at the line, where I create the model

Answer 1

You have add this line on SiteController.php Cause you are going to use VistorForm class inside the SiteController

use app\models\VisitorForm;
