[Solved] Subforms

Yii 2.0 General Discussions

What is the clean way to implement subforms in Yii2?

I mean, managing two diferent models (from diferent classes) in the same form.

Thanks! :)

Basically the same as it was in yii 1. You can use Model::validateMultiple() if you have an array of models. Check out https://github.com/yiisoft/yii2/issues/3306 for an example. Have not checked the correctness of the code in that issue but the one in the initial post looks right to me to get the idea.

@CeBe I’ve already seen the docs about validating an array of models, but in that case the model Class is the same.

What I need is embed two different Class models in the same form.

The typical example is creating a User and filling the profile in the same form.

What I’m doing right now is something like (not real example):




// Controller

//

public function actionCreate()

{   

    $user = new User;

    $profile = new Profile;


    if ($user->load(Yii::$app->request->post()) && $user->save()) {

        

        $profile->user_id = $user->id;

        $profile->save();

        

        return $this->redirect(['view', 'id' => $user->id]);

    } else {

        return $this->render('create', [

            'user' => $user,

            'profile' => $profile,

        ]);

    }

}


// View

// 

<?= $form->field($profile, 'lastname')->textInput(['maxlength' => 30]) ?>


<?= $form->field($profile, 'firstname')->textInput(['maxlength' => 30]) ?>


<?= $form->field($user, 'email')->textInput(['maxlength' => 255]) ?>

...

// and so on

...

But one of the problems is for example validate the "profile" data before saving the "user"…

Should I use this approach and manually validate both of them before trying to save?

Maybe I am missing something and there is a correct way to do this…

Thanks!

    if ($user->load(Yii::$app->request->post()) && $profile->load(Yii::$app->request->post()) && Model::validateMultiple([$user, $profile])) {

        

        $user->save(false); // skip validation as model is already validated

        $profile->user_id = $user->id; // no need for validation rule on user_id as you set it yourself

        $profile-save(false); 

        

        return $this->redirect(['view', 'id' => $user->id]);

    } else {

        return $this->render('create', [

            'user' => $user,

            'profile' => $profile,

        ]);

    }

}

You are the man! :)

Thanks. This is useful. I extended this approach for tabular data collection.

7

is there any update sample code is available for multi model?

8

This tutorial can maybe help you.

What we could do if it was profiles not a profile. i.e hasToMany. In other words, suppose that it is Invoice -> Items relationship i.e one invoice may has several items?

10

This tutorial has a missed code:


getItemsToUpdate()

is not defined and there is no any hint about it.
