EAV Dynamic Attributes for Yii2

Configuration

Take a look at the examples/m140423_034003_object.php file and create your own data structure depending on the entity you are using. I the most cases you'll need to change only the $entityName variable. For example:

$entityName="user_profile";

Extend all models you'll find in the yarcode\eav\models namespace and place them under the unique namespace. For example common\models\user_profile_eav.

Attach behavior to your model and define the getEavAttributes relation:

/**
 * @inheritdoc
 */
public function behaviors()
{
    return [
        [
            'class' => \yarcode\eav\EavBehavior::className(),
            'valueClass' => \common\models\user_profile_eav\AttributeValue::className(),
        ],
    ];
}

/**
 * @return yii\db\ActiveQuery
 */
public function getEavAttributes()
{
    $query = \common\models\user_profile_eav\Attribute::find();
    $query->multiple = true;
    return $query;
}

Rendering

Controller example

public function actionProfileFields()
{
    $model = Yii::$app->user->identity->profile;
    $model->setScenario(UserProfile::SCENARIO_UPDATE);

    /** @var DynamicModel $eav */
    $eav = $model->getEavModel();

    if ($eav->load(Yii::$app->request->post()) && $eav->validate()) {
        $dbTransaction = Yii::$app->db->beginTransaction();
        try {
            $eav->save(false);
            $dbTransaction->commit();
        } catch (\Exception $e) {
            $dbTransaction->rollBack();
            throw $e;
        }
        return $this->redirect(['index']);
    }

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

View example

<?php $form = ActiveForm::begin(); ?>

<?php
$eav->activeForm = $form;
foreach ($eav->handlers as $handler) {
    echo $handler->run();
}
?>

<div class="form-group">
    <?= Html::submitButton('Save', ['class' => 'btn btn-primary', 'name' => 'save-button']) ?>
</div>

<?php ActiveForm::end(); ?>
