the field for take file url in my table is varchar(500).

i am following yii2 documentation i haven't problem but it save one file.

my model: i put

 public $files;

[['files'], 'safe'],

[['files'], 'file', 'skipOnEmpty' => false, 'extensions' => 'pdf, gif, jpg, png', 'maxFiles' => 4],


my form : i put this line:  <?= $form->field($model, 'files[]')->fileInput(['multiple' => true, 'accept' => 'image/*' ]) ?>


my controller:

 public function actionUpdate($id)

    {

        $model = $this->findModel($id);


      

	$isStudent = Yii::$app->session->get('user_id');

 if ($model->load(Yii::$app->request->post())){	

    $model->files = UploadedFile::getInstances($model, 'files');

  

  

   foreach ($model->files as $files) {

    $save_file = '';

     $folder= 'uploads/'.$isStudent.'/localisation/';

     

      if($files){

   

    if(!is_dir($folder)){

				mkdir($folder, 0755, true);

			}


       

		$model->doc_loc = $folder.rand(10,100).'-'.$files->name;

		$model->id_etab = $isStudent;

		$model->created_by = Yii::$app->user->id;

		

		$save_file = 1; 

    }	

   if($model->save()) {

            if($save_file){

	//foreach ($model->files as $files) {

                $files->saveAs($model->doc_loc);

	//}

            }

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

        } 

	

	}  

	}else {

            return $this->render('update', [

                'model' => $model,

            ]);

        }

    }

use yii\web\UploadedFile;

In Controller:

$Model = new ModelClass;

$rnd = substr(str_replace(’.’, ‘’, uniqid(rand(), true)), 8, 10);

$loadedPost = $Model->load(Yii::$app->request->post());

if(UploadedFile::getInstances($Model, ‘opp_file’))

{

&#036;filenames = [];


&#036;uploadedFile2 = UploadedFile::getInstances(&#036;Model, 'opp_file');


if(isset(&#036;uploadedFile2) &amp;&amp; &#33;empty(&#036;uploadedFile2))


{


	foreach(&#036;uploadedFile2 as &#036;uploadedFile)


	{


		&#036;fileName2 = &quot;{&#036;rnd}-{&#036;uploadedFile}&quot;;


		&#036;filenames[] = &#036;fileName2;


		&#036;lc_data_file_path[] = Yii::&#036;app-&gt;basePath.'/..path-to-folder'.&#036;fileName2;


	}


}


&#036;Model-&gt;opp_file = implode(',',&#036;filenames);

}

if ($loadedPost && $Model->validate())

{

if(isset(&#036;uploadedFile2) &amp;&amp; &#33;empty(&#036;uploadedFile2)) 


{


	foreach(&#036;uploadedFile2 as &#036;filekey=&gt;&#036;uploadedsavefile)


	{


		&#036;uploadedsavefile-&gt;saveAs(&#036;lc_data_file_path[&#036;filekey]);


	}


}

}

It really works.
