Usage ¶

This extension provides support for ActiveRecord hasMany relation saving. This support is granted via \solutosoft\linkmany\LinkManyBehavior ActiveRecord behavior. You'll need to attach it to your ActiveRecord class and point the target "has-many" relation for it:

class Post extends ActiveRecord
{
    public function behaviors()
    {
        return [
            'linkManyBehavior' => [
                'class' => LinkManyBehavior::class,
                'relations' => [
                    'tags',
                    'messages' => [
                        'formName'  => 'Post[messages]',
                        'validate' => false,
                        'deleteOnUnlink' => false
                    ]
                ]
            ],
        ];
    }

    public function getMessages()
    {
        return $this->hasMany(Message::class, ['post_id' => 'id']);
    }

    public function getTags()
    {
        return $this->hasMany(Tag::class, ['id' => 'tag_id'])
            ->viaTable('post_tag', ['post_id' => 'id']);
    }
}

Being attached \solutosoft\linkmany\LinkManyBehavior you can load data using the method \solutosoft\linkmany\LinkManyBehavior::fill

use yii\web\Controller;

class PostController extends Controller
{
    public function actionCreate()
    {
        $model = new Post();

        if ($model->fill(Yii::$app->request->post())) {
            $model->save(); // save the model and relations
            return $this->redirect(['view']);
        }

        return $this->render('create', [
            'model' => $model,
        ]);
    }
}

This Package is inspired by:

• yii2tech/ar-linkmany.

I wanted to have a combination of both. Thanks to both authors.
