Require source

composer require "fruktozets/yii2-dropzone"

Execute migration

'controllerMap' => [
    'migrate' => [
        ...
        'migrationNamespaces' => [
            ...
            'fruktozets\dropzone',
        ],
    ],
],

Create a table linking the image and the owner.

$this->createTable('user_to_file', [
    'user_id' => $this->integer(),
    'file_id' => $this->integer(),
    //'type' => $this->smallInteger()->notNull()->defaultValue(2),

]);

Use widget

echo $form->field($model, 'images')->widget(DropZone::className(), [
    'uploadUrl' => ['site/upload'],
]) 

Use action

public function actions()
{
   return [
       'upload' => [
           'class' => 'fruktozets\dropzone\actions\UploadAction',
           'fileRule' => ['file', 'file', 'extensions' => ['jpg'], 'maxSize' => 1024*1024],
       ],

   ];
}

Implement IAttachable interface

class UserToFile extends \yii\db\ActiveRecord implements IAttachable

Use behavior

WARNING! "behavior" name must be equal "attribute" name! If you want to use MultipleFilesBehavior don't forget to add 'attribute' which associated with files to your model.

Use MultipleFilesBehavior for multiple files linked via third party table

public function behaviors()
{
    $behaviors = parent::behaviors();
    
    $behaviors['images'] = [
        'class' => MultipleFilesBehavior::class,
        'attribute' => 'images',
        'linkModelClass' => UserToFile::class,
        'additionalProperties' => ['type' => UserToFile::TYPE_IMAGE_MAIN,],
    ];

    return $behaviors;
}

Use FileBehavior for single file

public function behaviors()
{
    $behaviors = parent::behaviors();
    
    $behaviors['image_id'] = [
        'class' => FileBehavior::class,
        'attribute' => 'image_id',
    ];

    return $behaviors;
}

Do not forget to add your property to the rules in the model.

public function rules()
{
    return [
        ```
        [['images'], 'safe'],
    ];
}
