The use case

You need form input for separate model objects in your application.

Installation

$ composer require flaviovs/yii2-form

How to

1. Create your form model. Add composing models as normal attributes:

   class MyForm extends fv\yii\form\Model
   {
   	/** @var \app\models\Post */
   	public $post;
   
   	/** @var \app\models\Comment */
   	public $comment;
   }

2. Add the modelAttributes() function, which indicates which form attributes contain models to be loaded on submission:

   protected function modelAttributes()
   {
   	return ['post', 'comment'];
   }

3. Add validation rules for the models:

   protected function rules()
   {
       return [
           [$this->modelAttributes(), 'safe'];
       ];
   }

4. Add input controls to your views as you normally would. Just remember to reference model attributes of the form, instead of the form model itself.

   /** @var \fv\yii\form\Model $model */
   
   $form = ActiveForm::begin();
   
   echo $form->field($model->post, 'title');
   echo $form->field($model->comment, 'body');
   
   ActiveForm::End();

5. Process the form as you normally do:

   $model = new MyForm([
   	'post' => new Post(),
   	'comment' => new Comment(),
   ]);
   if ($model->load(\Yii::$app->request->post()) && $model->validate()) {
   	$model->post->save();
   	$model->comment->save();
   }
