This article describes the YII2 implementation of Ajax upload image plug-in usage. Share to everyone for your reference, specific as follows:

Here you need to download the mdmsoft/yii2-upload-file. Plugin 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
  ]); c11/>//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

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