Storage

October CMS provides a powerful filesystem abstraction thanks to Laravel and the wonderful Flysystem (opens new window) PHP package. The Flysystem integration provides simple to use drivers for working with local filesystems and Amazon S3. Even better, it's amazingly simple to switch between these storage options as the API remains the same for each system.

# Configuration

The filesystem configuration file is located at config/filesystems.php. Within this file you may configure all of your "disks". Each disk represents a particular storage driver and storage location. Example configurations for each supported driver is included in the configuration file. So, simply modify the configuration to reflect your storage preferences and credentials.

Of course, you may configure as many disks as you like, and may even have multiple disks that use the same driver.

# The Local Driver

When using the local driver, note that all file operations are relative to the root directory defined in your configuration file. By default, this value is set to the storage/app directory. Therefore, the following method would store a file in storage/app/file.txt:

Storage::disk('local')->put('file.txt', 'Contents');

# Other Driver Prerequisites

Before using the S3 driver, you will need to install the Flysystem S3 package via the Composer package manager.

composer require league/flysystem-aws-s3-v3 "^3.0"

The S3 driver configuration information is located in your config/filesystems.php configuration file. This file contains an example configuration array for an S3 driver. You are free to modify this array with your own S3 configuration and credentials.

# Basic Usage

# Obtaining Disk Instances

The Storage facade may be used to interact with any of your configured disks. For example, you may use the put method on the facade to store an avatar on the default disk. If you call methods on the Storage facade without first calling the disk method, the method call will automatically be passed to the default disk:

$user = User::find($id);

Storage::put(
    'avatars/'.$user->id,
    file_get_contents(Request::file('avatar')->getRealPath())
);

When using multiple disks, you may access a particular disk using the disk method on the Storage facade. Of course, you may continue to chain methods to execute methods on the disk:

$disk = Storage::disk('s3');

$contents = Storage::disk('local')->get('file.jpg')

# Retrieving Files

The get method may be used to retrieve the contents of a given file. The raw string contents of the file will be returned by the method:

$contents = Storage::get('file.jpg');

The exists method may be used to determine if a given file exists on the disk:

$exists = Storage::disk('s3')->exists('file.jpg');

# File Meta Information

The size method may be used to get the size of the file in bytes:

$size = Storage::size('file1.jpg');

The lastModified method returns the UNIX timestamp of the last time the file was modified:

$time = Storage::lastModified('file1.jpg');

# Storing Files

The put method may be used to store a file on disk. You may also pass a PHP resource to the put method, which will use Flysystem's underlying stream support. Using streams is greatly recommended when dealing with large files:

Storage::put('file.jpg', $contents);

Storage::put('file.jpg', $resource);

The copy method may be used to copy an existing file to a new location on the disk:

Storage::copy('old/file1.jpg', 'new/file1.jpg');

The move method may be used to move an existing file to a new location:

Storage::move('old/file1.jpg', 'new/file1.jpg');

# Prepending / Appending to Files

The prepend and append methods allow you to easily insert content at the beginning or end of a file:

Storage::prepend('file.log', 'Prepended Text');

Storage::append('file.log', 'Appended Text');

# Deleting Files

The delete method accepts a single filename or an array of files to remove from the disk:

Storage::delete('file.jpg');

Storage::delete(['file1.jpg', 'file2.jpg']);

# Directories

# Get All Files Within a Directory

The files method returns an array of all of the files in a given directory. If you would like to retrieve a list of all files within a given directory including all sub-directories, you may use the allFiles method:

$files = Storage::files($directory);

$files = Storage::allFiles($directory);

# Get All Directories Within a Directory

The directories method returns an array of all the directories within a given directory. Additionally, you may use the allDirectories method to get a list of all directories within a given directory and all of its sub-directories:

$directories = Storage::directories($directory);

// Recursive...
$directories = Storage::allDirectories($directory);

# Create a Directory

The makeDirectory method will create the given directory, including any needed sub-directories:

Storage::makeDirectory($directory);

# Delete a Directory

Finally, the deleteDirectory may be used to remove a directory, including all of its files, from the disk:

Storage::deleteDirectory($directory);
