Yii2 Flysystem

The League Flysystem for local and remote filesystems library for Yii2.

This extension provides Flysystem 3 integration for the Yii framework. Flysystem is a filesystem abstraction which allows you to easily swap out a local filesystem for a remote one.

Yii2 Flysystem uses league/flysystem

Instalation

Package is available on Packagist, you can install it using Composer.

composer require diecoding/yii2-flysystem "^1.0"

or add to the require section of your composer.json file.

"diecoding/yii2-flysystem": "^1.0"

Additional Configuration

URL File Action Settings

The following adapters have URL File Action generation capabilities:

Local Component
FTP Component
SFTP Component
Google Drive Component

Configure action in controller as follows

This example at SiteController for /site/file

class SiteController extends Controller
{
    //...
    public function actions()
    {
        return [
            // ...
            'file' => [
                'class' => \diecoding\flysystem\actions\FileAction::class,
                // 'component' => 'fs',
            ],
        ];
    }
}

Remember to configure action key in fs application components as follows

return [
    // ...
    'components' => [
        // ...
        'fs' => [
            // ...
            'action' => '/site/file', // action for get url file
        ],
    ],
];

Global Visibility Settings

Configure fs application component as follows

return [
    //...
    'components' => [
        //...
        'fs' => [
            //...
            'config' => [
                'visibility' => \League\Flysystem\Visibility::PRIVATE,
            ],
        ],
    ],
];

Usage

Writing or Updating Files

To write or update file

Yii::$app->fs->write('filename.ext', 'contents');

To write or update file using stream contents

$stream = fopen('/path/to/somefile.ext', 'r+');
Yii::$app->fs->writeStream('filename.ext', $stream);

Reading Files

To read file

$contents = Yii::$app->fs->read('filename.ext');

To retrieve a read-stream

$stream = Yii::$app->fs->readStream('filename.ext');
$contents = stream_get_contents($stream);
fclose($stream);

Checking if a File Exists

To check if a file exists

$exists = Yii::$app->fs->fileExists('filename.ext');

Deleting Files

To delete file

Yii::$app->fs->delete('filename.ext');

Getting Files Mime Type

To get file mime type

$mimeType = Yii::$app->fs->mimeType('filename.ext');

Getting Files Timestamp / Last Modified

To get file timestamp

$timestamp = Yii::$app->fs->lastModified('filename.ext');

Getting Files Size

To get file size

$byte = Yii::$app->fs->fileSize('filename.ext');

Creating Directories

To create directory

Yii::$app->fs->createDirectory('path/to/directory');

Directories are also made implicitly when writing to a deeper path

Yii::$app->fs->write('path/to/filename.ext');

Checking if a Directory Exists

To check if a directory exists

$exists = Yii::$app->fs->directoryExists('path/to/directory');

Deleting Directories

To delete directory

Yii::$app->fs->deleteDirectory('path/to/directory');

Checking if a File or Directory Exists

To check if a file or directory exists

$exists = Yii::$app->fs->has('path/to/directory/filename.ext');

Managing Visibility

Visibility is the abstraction of file permissions across multiple platforms. Visibility can be either public or private.

Yii::$app->fs->write('filename.ext', 'contents', [
    'visibility' => \League\Flysystem\Visibility::PRIVATE
]);

You can also change and check visibility of existing files

if (Yii::$app->fs->visibility('filename.ext') === \League\Flysystem\Visibility::PRIVATE) {
    Yii::$app->fs->setVisibility('filename.ext', \League\Flysystem\Visibility::PUBLIC);
}

Listing contents

To list contents

$contents = Yii::$app->fs->listContents();

foreach ($contents as $object) {
    echo $object['basename']
        . ' is located at' . $object['path']
        . ' and is a ' . $object['type'];
}

By default Flysystem lists the top directory non-recursively. You can supply a directory name and recursive boolean to get more precise results

$contents = Yii::$app->fs->listContents('path/to/directory', true);

Copy Files or Directories

To copy contents

Yii::$app->fs->copy('path/from/directory/filename.ext', 'path/to/directory/filename.ext', [
    'visibility' => \League\Flysystem\Visibility::PRIVATE
]);

Move Files or Directories

To move contents

Yii::$app->fs->move('path/from/directory/filename.ext', 'path/to/directory/filename.ext', [
    'visibility' => \League\Flysystem\Visibility::PRIVATE
]);

Get URL Files

To get url contents

Yii::$app->fs->publicUrl('path/to/directory/filename.ext');

Get URL Temporary Files / Presigned URL

To get temporary url contents

$expiresAt = new \DateTimeImmutable('+10 Minutes');

Yii::$app->fs->temporaryUrl('path/to/directory/filename.ext', $expiresAt);

The $expiresAt should be a valid and instance of PHP DateTimeInterface. Read PHP documentation for details.

Get MD5 Hash File Contents

To get MD5 hash of the file contents

Yii::$app->fs->checksum('path/to/directory/filename.ext');

Using Traits

Model Trait

Attach the Trait to the Model/ActiveRecord with some media attribute that will be saved in Flysystem (fs):

/**
 * @property string|null $file
 */
class Model extends \yii\db\ActiveRecord
{
    use \diecoding\flysystem\traits\ModelTrait;

    // ...

    public function rules()
    {
        return [
            ['image', 'string'], // Stores the filename
        ];
    }

    /**
     * @inheritdoc
     */
    protected function attributePaths()
    {
        return [
            'image' => 'images/'
        ];
    }

    // ...
}

Override the attributePaths() method to change the base path where the files will be saved on Flysystem (fs).

You can map a different path to each file attribute of your Model/ActiveRecord.

Using Trait Methods

$image = \yii\web\UploadedFile::getInstance($model, 'image');

// Save image_thumb.* to Flysystem (fs) on //my_bucket/images/ path
// The extension of the file will be determined by the submitted file type
// This allows multiple file types upload (png,jpg,gif,...)
// $model->image will hold "image_thumb.png" after this call finish with success
$model->saveUploadedFile($image, 'image', 'image_thumb');
$model->save();

// Save image_thumb.png to Flysystem (fs) on //my_bucket/images/ path
// The extension of the file will be determined by the submitted file type
// This force the extension to *.png
$model->saveUploadedFile($image, 'image', 'image_thumb.png', false);
$model->save();

// Remove the file with named saved on the image attribute
// Continuing the example, here "//my_bucket/images/my_image.png" will be deleted from Flysystem (fs)
$model->removeFile('image');
$model->save();

// Get the URL to the image on Flysystem (fs)
$model->getFileUrl('image');

// Get the presigned URL to the image on Flysystem (fs)
// The default duration is "+5 Minutes"
$model->getFilePresignedUrl('image');

Overriding Trait Methods

getFsComponent

The Flysystem (fs) MediaTrait depends on this component to be configured. The default configuration is to use this component on index 'fs', but you may use another value. For this cases, override the getFsComponent() method:

public function getFsComponent()
{
    return Yii::$app->get('my_fs_component');
}

attributePaths

The main method to override is attributePaths(), which defines a path in Flysystem (fs) for each attribute of yout model. Allowing you to save each attribute in a different Flysystem (fs) folder.

Here an example:

protected function attributePaths()
{
    return [
        'logo' => 'logos/',
        'badge' => 'images/badges/'
    ];
}

// or use another attribute, example: id
// ! Note: id must contain a value first if you don't want it to be empty

protected function attributePaths()
{
    return [
        'logo' => 'thumbnail/' . $this->id . '/logos/',
        'badge' => 'thumbnail/' . $this->id . '/images/badges/'
    ];
}

getPresignedUrlDuration

The default pressigned URL duration is set to "+5 Minutes", override this method and use your own expiration. Return must instance of DateTimeInterface

protected function getPresignedUrlDuration($attribute)
{
    return new \DateTimeImmutable('+2 Hours');
}

// or if you want to set the attribute differently

protected function getPresignedUrlDuration($attribute)
{
    switch ($attribute) {
        case 'badge':
            return new \DateTimeImmutable('+2 Hours');
            break;
        
        default:
            return new \DateTimeImmutable('+1 Days');
            break;
    }
}

The value should be a valid and instance of PHP DateTimeInterface. Read PHP documentation for details.
