Yii.js stop form submit uploading large files

Hi all, I’ve just updated my php.ini file on my server with all settings and rebooted apache.

Infact, I try this simple script out of Yii2 and i uploaded succesfully an image of 25Mb.


<form enctype="multipart/form-data" action="upload.php" method="POST">

    <p>Upload your file</p>

    <input type="file" name="uploaded_file" ></input><br />

    <input type="submit" value="Upload"></input>




    $path = "uploads/";

    $path = $path . basename( $_FILES['uploaded_file']['name']);

    if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $path)) {

        echo "The file ".  basename( $_FILES['uploaded_file']['name']).

            " has been uploaded";

    } else{

        echo "There was an error uploading the file, please try again!";




Now I have a simple form in Yii2 like this:

<?php $form = ActiveForm::begin([

    'id' => 'file-upload-image',

    'fieldConfig' => [

        'options' => [

            'tag' => false,




]); ?>

<?= $form->field($imp, 'file[]')->fileInput(['multiple' => true, 'accept' => 'image/*']) ?>

<div class='box-footer'>

    <div class="form-group">

        <?= Html::submitButton('N>ext', ['class' => 'btn btn-success','style' => "margin: 10px auto; display: block;"]) ?>


    <?php ActiveForm::end(); ?>


My problem is that i’m able only to upload image until 10Mb (in my php.ini settings i set 200Mb both post_max_size and upload_max_filesize)

I don’t find any error message, in the console tab, in the network tab of my browser.

I see that the submit doesn’t start if i press submit button.

I try to debug Yii.js on submit button but i lose myself in the code and i can’t understand where’s the problem. I only see that it stop submit propagation for some reason.

Can anyone give me any help?


this is my model


namespace app\models;

use yii\base\Model;

use yii\web\UploadedFile;


 * UploadForm is the model behind the upload form.


class UploadForm extends Model



     * @var UploadedFile|Null file attribute


    public $file;


     * @return array the validation rules.


    public function rules()


        return [

            [['file'], 'file', 'extensions' => ['png', 'jpg', 'jpeg','gif'], 'maxSize' => 1024 * 1024 * 50],




Sorry i’, doing a very big error!

I duplicate that model when i’m trying to solve this at the very begin of my problem, and then i continue to use new model, but i think now i’m using the oldest.

So my problem is ‘maxSize’ validation rules of my model set to 1024 * 1024 * 10

I found this error after i put a

<?= $form->errorSummary($imp); ?>

in my form

Bye ;)
