Yii2 attachments

Extension for file uploading and attaching to the models

Installation

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

   Either run

   php composer.phar require dlds/yii2-attachments "*"
   

   or add

   "dlds/yii2-attachments": "*"
   

   to the require section of your composer.json file.

2. Apply migrations

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

3. Add module to config/main.php

   'modules' => [
   	...
   	'attachments' => [
   		'class' => dlds\attachments\Module::className(),
   		'tempPath' => '@app/uploads/temp',
   		'storePath' => '@app/uploads/store'
   	]
   	...
   ]

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

   public function behaviors()
   {
   	return [
   		...
   		'attachmentBehavior' => [
   		'class' => \dlds\attachments\behaviors\AttachmentBehavior::className()
   		]
   		...
   	];
   }

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

Usage

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

   <?= \kartik\file\FileInput::widget([
   	'name' => 'file[]',
   	'id' => 'file-input',
   	'options' => [
   		'multiple' => true, // false if you want to allow upload a single file
   	],
   	'pluginOptions' => [
   		'uploadUrl' => yii\helpers\Url::toRoute('/attachments/file/upload'), // remove this if you don't want to use AJAX uploading 
   		'initialPreview' => $model->isNewRecord ? [] : $model->getInitialPreview(),
   		'initialPreviewConfig' => $model->isNewRecord ? [] : $model->getInitialPreviewConfig(),
   		// other options
   	]
   ]); ?>

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

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

3. (Optional) 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');"
   ]) ?>
