Yii2 Dropzone

DropzoneJs Extention for Yii2

A port of DropzoneJs for Yii2 Framework

Installation

The preferred way to install this extension is through composer.

Either run

php composer.phar require --prefer-dist perminder-klair/yii2-dropzone "dev-master"

or add

"perminder-klair/yii2-dropzone": "dev-master"

to the require section of your composer.json file.

Usage

Once the extension is installed, simply use it in your code by to create Ajax upload area :

echo \kato\DropZone::widget();

To pass options : (More details at dropzonejs official docs )

echo \kato\DropZone::widget([
       'options' => [
           'maxFilesize' => '2',
       ],
       'clientEvents' => [
           'complete' => "function(file){console.log(file)}",
           'removedfile' => "function(file){alert(file.name + ' is removed')}"
       ],
   ]);

Example of upload method :

public function actionUpload()
{
    $fileName = 'file';
    $uploadPath = './files';

    if (isset($_FILES[$fileName])) {
        $file = \yii\web\UploadedFile::getInstanceByName($fileName);

        //Print file data
        //print_r($file);

        if ($file->saveAs($uploadPath . '/' . $file->name)) {
            //Now save file data to database

            echo \yii\helpers\Json::encode($file);
        }
    }

    return false;

Bad Request (#400)

There is a problem with the csrf token (Bad Request (#400)), so I added the csrf token :

'options' => [
    'url' => Url::to(['dropzone']),
    'headers' => [
        Yii::$app->getRequest()->csrfParam => Yii::$app->getRequest()->csrfToken
    ]
],

But it still not working. What is the solution ?
Waiting your answer I added public $enableCsrfValidation = false; in the Controller

Thank you

AutoDiscover configuration ignored

I'm using Chromium (Chrome) and I've a couple of errors in the javascript console:

Uncaught Error: No URL provided.
Uncaught Error: Dropzone already attached.

registerJs() by default bind/wrap its code to the onready event (using jQuery) and this addon use it to configure the AutoDiscover option to true or false.

asset::register() doesn't bind/wrap to anything, as it should be for any javascript library/module, it is included at the end of the body after its dependencies and executed as soon as possible.

The problem is that DropZone, at least the version used by this addon, execute as soon as possible a contentLoaded function that seems to bind to the onload event, when the content is loaded the autoDiscover start.

So what is happening (at least on the Chromium I'm using) is that the DropZone's autoDiscover function is executed before the addon javascript set the autoDiscover configuration.

Currently the only solution I've found is to add a new asset, with the js code to disable the autoDiscover, add to it DropZoneAsset as dependency, and in DropZone.php register it instead, but is far from optimal.
