BlueImp File Upload Widget for Yii2

Renders a BlueImp jQuery File Upload plugin. That plugin integrates multiple file selection, drag&drop support, progress bars, validation and preview of images.

Installation

The preferred way to install this extension is through composer.

Either run

$ composer require 2amigos/yii2-file-upload-widget:~1.0

or add

"2amigos/yii2-file-upload-widget": "~1.0"

to the require section of your composer.json file.

Usage

The widget comes with two flavors:

• FileUpload: Basic and BasicPlus
• FileUploadUI: BasicPlus UI

<?php
use dosamigos\fileupload\FileUpload;

// without UI
?>

<?= FileUpload::widget([
    'model' => $model,
    'attribute' => 'image',
    'url' => ['media/upload', 'id' => $model->id], // your url, this is just for demo purposes,
    'options' => ['accept' => 'image/*'],
    'clientOptions' => [
        'maxFileSize' => 2000000
    ],
    // Also, you can specify jQuery-File-Upload events
    // see: https://github.com/blueimp/jQuery-File-Upload/wiki/Options#processing-callback-options
    'clientEvents' => [
        'fileuploaddone' => 'function(e, data) {
                                console.log(e);
                                console.log(data);
                            }',
        'fileuploadfail' => 'function(e, data) {
                                console.log(e);
                                console.log(data);
