YII2 implement AJAX upload Image plugin usage _php instance

The example of this article describes the YII2 implementation of Ajax upload image plugin usage. Share to everyone for your reference, as follows:

You need to download the Mdmsoft/yii2-upload-file plugin here first.

The code is as follows:

Public Function Actioncreate () {  $model = new Dynamicmodel ([    ' Nama ', ' file_id '    ]);  Behavior Untuk upload file  $model->attachbehavior (' upload ', [    ' class ' = ' Mdm\upload\uploadbehavior ') ,    ' attribute ' = ' file ',    ' savedattribute ' = ' file_id '//coresponding with $model->file_id  ]);  Rule Untuk Model  $model->addrule (' Nama ', ' string ')    ->addrule (' file ', ' file ', [' extensions ' = ') ' JPG ']);  if ($model->load (Yii:: $app->request->post ()) && $model->validate ()) {    if ($model- Saveuploadedfile ()!== false) {      Yii:: $app->session->setflash (' success ', ' Upload sukses ');    }  }  return $this->render (' Upload ', [' model ' = + $model]);

Then in view upload.php

<?phpuse yii\helpers\html;use yii\widgets\activeform;/* @var $this yii\web\view */?>  <?php  $form = Activeform::begin ([      ' options '] = [' enctype ' = ' multipart/form-data ']  );  >  <?= $form->field ($model, ' Nama ');?>  <?= $form->field ($model, ' file ')->fileinput ();? >  <?php if ($model->file_id):?>          <?= html::img (['/file ', ' id ' = = $model->file_id])? >< c9/><?php endif;?>      <?= Html::submitbutton (' Submit ', [' class ' = ' btn btn-primary '])?>    <? PHP activeform::end ();?>
