Public $file;


Public function Rules () {
return [

[[' File '], ' file ', ' extensions ' = ' jpg, png ', ' mimetypes ' = ' image/jpeg, Image/png ',],
        ];
    }


Public function Attributelabels () {
return [
' file ' = ' files upload '
        ];
    }
}   

uploadform.php [multi-file upload model]

<?php
namespace App\models;

Use Yii;
Use Yii\base\model;

class Uploadform extends Model
{
    /**
* @var uploadedfile| Null file attribute
     */
Public $file;

    /**
* @return Array the validation rules.
     */
Public function rules ()
    {
return [
[[' File '], ' file ', ' maxfiles ', ' extensions ' = ' jpg,png,gif '],
        ];
    }

Public function Attributelabels () {
return [
' file ' + ' Multiple files upload '
        ];
    }

Use app\models\uploadform;
Use yii\web\uploadedfile;

class TestController extends controller{

Public function Actionindex () {
return $this->renderpartial (' index ');
    }

    /**
* @return String|\yii\web\response
* Single File Upload
     */
Public function Actionupload () {
$model = new Upload ();

if (Yii:: $app->request->ispost) {
$file = uploadedfile::getinstance ($model, ' file ');
$path = ' uploads/'. Date ("Ymdh", Time ()). ' /';
if ($file && $model->validate ()) {
if (!file_exists ($path)) {
mkdir ($path, 0775,true);
                }
$file->saveas ($path. Time (). ‘.‘ . $file->getextension ());
Yii:: $app->session->setflash (' success ', ' upload success! ');
return $this->redirect (' upload ');
            }
        }

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


Public function Actionupmore () {
$model = new Uploadform ();
if (Yii:: $app->request->ispost) {
$file = uploadedfile::getinstances ($model, ' file ');

if ($file && $model->validate ()) {
echo "<pre/>";

foreach ($file as $FL) {
$fl->saveas (' uploads/'. Mt_rand (1100,9900). Time (). $FL->basename. ‘.‘ . $FL->extension);
                }
Yii:: $app->session->setflash (' success ', ' upload success! ');
return $this->redirect (' Upmore ');
            }
        }

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