Installation

The preferred way to install this extension is through composer.

or add

"solutosoft/yii-linkmany": "*"

to the require section of your composer.json.

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();


        /**
         * $_POST could be something like:
         * [
         *     'tags' => [1,2]
         *     'comments' => [
         *         [
         *             'subject' => 'First comment',
         *             'content' => 'This is de fist comment',
         *         ], [
         *             'subject' => 'Second comment',
         *             'content' => 'This is de second comment',
         *         ]
         *     ]
         * ];
         */
        if ($model->fill(Yii::$app->request->post())) {
            $model->save(); // save the model and relations
            return $this->redirect(['view']);
        }

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