Installation

1. The preferred way to install this extension is through composer.

   Either run

   composer require axelpal/yii2-attachments "dev-master"
   

   or add

   "axelpal/yii2-attachments": "dev-master"
   

   to the require section of your composer.json file.

2. Add module to your main config:

   'aliases' => [
           '@file' => dirname(__DIR__),
       ],
       'modules' => [
           'file' => [
               'class' => 'file\FileModule',
               'webDir' => 'files',
               'tempPath' => '@common/uploads/temp',
               'storePath' => '@common/uploads/store',
               'rules' => [ // Правила для FileValidator
                   'maxFiles' => 20,
                   'maxSize' => 1024 * 1024 * 20 // 20 MB
               ],
           ],
       ],

   Also, add these lines to your console config:

   'controllerMap' => [
           'file' => [
               'class' => 'yii\console\controllers\MigrateController',
               'migrationPath' => '@file/migrations'
           ],
       ],

3. Apply migrations

   php yii migrate/up --migrationPath=@vendor/axelpal/yii2-attachments/migrations
   

4. Attach behavior to your model (be sure that your model has "id" property)

   public function behaviors()
   {
   	return [
   		...
   		'fileBehavior' => [
   			'class' => \file\behaviors\FileBehavior::className()
   		]
   		...
   	];
   }

5. Make sure that you have added 'enctype' => 'multipart/form-data' to the ActiveForm options

6. Make sure that you specified maxFiles in module rules and maxFileCount on AttachmentsInput to the number that you want

Usage

1. In the form.php of your model add file input

   <?= \file\components\AttachmentsInput::widget([
   	'id' => 'file-input', // Optional
   	'model' => $model,
   	'options' => [ // Options of the Kartik's FileInput widget
   		'multiple' => true, // If you want to allow multiple upload, default to false
   	],
   	'pluginOptions' => [ // Plugin options of the Kartik's FileInput widget 
   		'maxFileCount' => 10 // Client max files
   	]
   ]) ?>

2. Use widget to show all attachments of the model in the view.php

   <?= \file\components\AttachmentsTable::widget(['model' => $model]) ?>

3. (Deprecated) Add onclick action to your submit button that uploads all files before submitting form

   <?= Html::submitButton($model->isNewRecord ? 'Create' : 'Update', [
   	'class' => $model->isNewRecord ? 'btn btn-success' : 'btn btn-primary',
   	'onclick' => "$('#file-input').fileinput('upload');"
   ]) ?>

4. You can get all attached files by calling $model->files, for example:

   foreach ($model->files as $file) {
       echo $file->path;
   }
