Photo gallery "before" & "after" (similarly).

Advantages

If the model needs files, you don't need:

define attribute file in a model,
to process the result of filling the form,
to come up with where save files,

You can:

add a description to the file,
delete no needed files,
define sizes to compress images,
crop images,
swap files rows by mouse.

How it's made?

Information about all uploaded files are stored in one table - onefile. There is no need to define a field of type file in the model, which need files.

The files are uploaded and stored in the directory frontend/web/files. For each model subdirectories are possible: frontend/web/files/user or frontend/web/files/post. In the subdirectory the files are arranged by users (or posts) and sizes:

frontend/web/files/user/2
frontend/web/files/user/2/thumb
frontend/web/files/user/2/original

Rows with uploaded files can be sorted dragging the rows with the mouse.

Example

User must can upload photos. Need to be defined in a model common/models/User:

...
use sergmoro1\uploader\FilePath;
use sergmoro1\uploader\models\OneFile;
...

class User extends ActiveRecord implements IdentityInterface
{
   ...
  // Images sizes
  public $sizes = [
    // Catalog original should be define for cropping
    'original' => ['width' => 1600, 'height' => 900, 'catalog' => 'original'],
    'main' => ['width' => 400, 'height' => 400, 'catalog' => ''],
    'thumb' => ['width' => 90, 'height' => 90, 'catalog' => 'thumb'],
  ];
  // Get ref to the file, make dir and so
  public function behaviors()
  {
    return [
      'FilePath' => [
        'class' => FilePath::className(),
        'file_path' => '/files/user/',
      ]
    ];
  }
  // All files for User model
  public function getFiles()
  {
    return OneFile::find()
      ->where('parent_id=:parent_id AND model=:model', [
        ':parent_id' => $this->id,
        ':model' => 'common\models\User',
       ])
      // only if rows should be draggable & sortable
      ->orderBy('created_at')
      ->all();
  }

  ...

Now User can uploading and files will be in:

  frontend/web/files/user/user_id
  frontend/web/files/user/user_id/original
  frontend/web/files/user/user_id/thumb

Thus, the sizes will be modified as specified.

To do uploading you need to place widget in a form or any other view. For ex. backend/views/user/_form.php:

use sergmoro1\uploader\widgets\Byone;
...

  <?= Byone::widget([
    'model' => $model,
    'cropAllowed' => true,
  ]) ?>

If image should be cropped (cropAllowed = true), subdirectory original need to be define. The aspect ratio for cropping is set on main subdirectory. By default, only main image will be cropped, but you can specify any other directory (except original) by defining the parameter crop.

  public $sizes = [
    'original' => ['width' => 3600, 'height' => 2400, 'catalog' => 'original'],
    'main' => ['width' => 400, 'height' => 400, 'catalog' => ''],
    'thumb' => ['width' => 120, 'height' => 80, 'catalog' => 'thumb', 'crop' => true],
  ];

May be uploaded any amount of files but files amount can be limited by maxFiles.

Installation

In app directory:

$ composer require sergmoro1/yii2-byone-uploader "dev-master"

Run migration:

$ php yii migrate --migrationPath=@vendor/sergmoro1/yii2-byone-uploader/migrations

To register the module in an app - common/config/main.php:

  'modules' => [
    'uploader' => [
      'class' => 'sergmoro1\uploader\Module',
  ],

If advanced template is used then before_web param should be defined. For example backend\config\params.php

<?php
return [
    'before_web' => 'backend',
    ...
];

For frontend or basic template no needed.

Description of uploaded files

You can leave comments to the files. To do this in the form backend/views/user/_form.php, in the already mentioned widget, you need to add the parameter appendeixView:

...
  <?= Byone::widget([
    'model' => $model,
    'appendixView' => '/user/appendix',
    'cropAllowed' => true,
  ]) ?>

And add view, for ex. backend/views/user/appendix.php the following content:

<span id='description'>
    <?php echo isset($file->vars->description) ? $file->vars->description : ''; ?>
</span>

Field description defined by default, but fields not limited.

Options

cropAllowed (false) If image should be cropped, 'original' size must be defined in $sizes array of the model.

draggable (false) If uploaded files should be swapped then in a getter getFiles() rows must be sorted by created_at.

  public function getFiles()
  {
    return OneFile::find()
      ->where('parent_id=:parent_id AND model=:model', [
        ':parent_id' => $this->id,
        ':model' => 'common\models\YourModel',
       ])
      ->orderBy('created_at')
      ->all();
  }
