Demo

You can see the demo on the krajee website

Installation

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

Either run

composer require badbreze/yii2-attachments

or add

"badbreze/yii2-attachments": ">=1.2.0"

to the require section of your composer.json file.

2. Add module to your main config:

<?php
'aliases' => [
    '@file' => dirname(__DIR__),
],
'modules' => [
    'file' => [
        'class' => 'file\FileModule',
        'webDir' => 'files',
        'tempPath' => '@common/uploads/temp',
        'storePath' => '@common/uploads/store',
        'tableName' => '{{%attach_file}}' // Optional, default to 'attach_file'
    ],
],

Also, add these lines to your console config:

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

3. Apply migrations

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

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

<?php
use yii\helpers\ArrayHelper;

/**
 * Declare file fields
 */
public $my_field_multiple_files;
public $my_field_single_file;

/**
 * Adding the file behavior
 */
public function behaviors()
{
    return ArrayHelper::merge(parent::behaviors(), [
        'fileBehavior' => [
            'class' => \file\behaviors\FileBehavior::className()
        ]
    ]);
}

/**
 * Add the new fields to the file behavior
 */
public function rules()
{
    return ArrayHelper::merge(parent::rules(), [
        [['my_field_multiple_files', 'my_field_single_file'], 'file'],
    ]);
}

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
