Before we talked about how to use modal in yii2 and how to use modal in the Yii2 GridView list, I thought modal would be over to start a new topic, but the actual problem is often beyond imagination. This does not modal the window submitted by the table is how to verify the problem and come out again, come out again!

The essence of the problem is not modal, the core of the problem lies in the ActiveForm of the asynchronous verification, solve the first contradiction, we have solved the problem of this article. By the way, dinning a sentence, modal really have nothing to say. I'll change the words back if I have them back.

YII2, ActiveForm does client-side validation by default, but the form's submission is not without a refresh. That is, the page is refreshed when the form is often seen. If you want to turn on the no-refresh mode, just start enableajaxvalidation on ActiveForm, like this

 
  ' Form-id ',        ' enableajaxvalidation ' = True,        ' validationurl ' = Url::toroute ([' Validate-form ']),    ] );?>

Note that neither the ID nor the enableajaxvalidation can be less than one.

About Validateurl we make a note. If you do not set this parameter, the address is your current route by default, and it happens that your current route is the action of form form, you will be curious to find that when the form item input loses focus, your changes to the data have been submitted to the backend to be processed? This is often not what we want, at this time we need to set a routing address for validateurl, the meaning of the operation to be requested is to do the verification asynchronously! We look at the specific implementation:

Form submission operation, basically do not need to make changes if ($model->load (Yii:: $app->request->post ()) && $model->save ()) {        return $this->redirect ([' Index ']);}    } return $this->render (' Create ', [    ' model ' = $model,]);//@see Http://www.manks.top/yii2_modal_activeform_ ajax.html//See the primary validation action, which is an asynchronous validation when the form field loses focus, and if the form is submitted directly, the action is also performed to verify public function Actionvalidateform () {    yii::$ App->response->format = \yii\web\response::format_json;    $model = new Model ();      $model->load (Yii:: $app->request->post ());      Return \yii\widgets\activeform::validate ($model);  }

In this way, the Yii2 asynchronous no-refresh form verification is implemented simply!

The topic of this issue is short but the content is exquisite, hope to be helpful to you!
