or add

Usage

Once the extension is installed, add the behavior to ActiveRecord model as follow:

Create a model with a file attribute

class Model extends \yii\db\ActiveRecord
{
    /**
     * @inheritdoc
     */
    public function behaviors()
    {
        return [
            'upload' => [
                 'class' => '\tigrov\uploadBehavior\UploadBehavior',
                 'path' => '@runtime/upload',
                 'attributes' => ['file'],
            ],
        ];
    }
    
    /**
     * @inheritdoc
     */
    public function rules()
    {
        return [
            [['file'], 'file', 'skipOnEmpty' => false],
        ];
    }
}

Create an action in a controller

class FormController extends \yii\web\Controller
{
    public function actionUpload()
    {
        $model = new Model();
        if ($model->load(\Yii::$app->request->post()) && $model->save()) {
            \Yii::$app->getSession()->setFlash('success', 'Model is saved.');
            return $this->refresh();
        }

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

Create a form with the file attribute

<?php $form = ActiveForm::begin(); ?>
    <?= $form->field($model, 'file')->fileInput() ?>
    <?= Html::submitButton('Submit') ?>
<?php $form::end(); ?>

After submitting the file it will be saved to specified path.
