MultipleInput and validation on creation

Yii 2.0 General Discussions

Hello there,

I’m facing a problem when I try to inform the user the result of the validation of multiple models using yii2-multiple-input.

I have a Policy with many Rules. On the Controller I pre-validate the rules and if they’re all ok, I save the policy and then its rules. But I find any error on the Rules, how I can inject them into the parent model the Rules in order yii2-multiple-input show it (e.g. $model->rules) ?

Controller:

public function actionCreate()
{
    $model = new Policy();

		if( $model->load(Yii::$app->request->post()) && $status= $model->validate() )
		{
			if( isset( Yii::$app->request->post()['Policy']['rules'] ) )
			{
				$objRules = array();

				foreach( Yii::$app->request->post()['Policy']['rules'] as $index => $ruleAttributes )
				{
					$objRules[ $index ] = new Rule( $ruleAttributes );
					$status&= $objRules[ $index ]->validate();
				}

				if( $status && $model->save() )
				{
					foreach( $objRules as $objRule )
					{
						$objRule->policy_id = $model->id;
						$status&= $objRule->save();
					}
				}
			}

			if( $status )
				return $this->redirect(['view', 'id' => $model->id]);
    }

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

View:

<?=
	$form->field( $model, 'rules')->label(false)->widget(MultipleInput::className(), [
		'max' => 16,
		'columns' => [
			[
				'name'  => 'name',
				'title'  => 'name',
				'defaultValue' => Null,
			],
			[
				'name'  => 'direction',
				'title'  => 'direction',
				'type'	=> MultipleInputColumn::TYPE_DROPDOWN,
				'defaultValue' => 0,
				'items' => [
					0 => 'Ingress',
					1 => 'Egress',
				],
				'headerOptions' => [
					'style' => 'width: 150px;',
				],
			],
        [...]

Thank you.

I solved using TabularInput on the view and sorting out with arrays in the Controller:

public function actionCreate()
{
    $model = new Policy();
	$rules = [];

	if( $model->load(Yii::$app->request->post()) && ( $status = $model->validate() ) )
	{
		foreach( Yii::$app->request->post()['Rule'] as $index => $attributes )
		{
			$rules[ $index ] = new Rule( $attributes );
			$status&= $rules[ $index ]->validate();
		}

		if( $status && $model->save() )
		{
			foreach( $rules as $rule )
			{
				$rule->policy_id = $model->id;
				$status&= $rule->save();
			}
		}

		if( $status )
			return $this->redirect(['view', 'id' => $model->id]);
    }
	else
		$rules = [ new Rule() ];

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

But I couldn’t implement it with loadMultiple()… perhaps the latter is a way to avoid the duplicated foreach().
