Flysystem Public URL Plugin

This repo is a plugin for the Flysystem PHP library.

It allows you to get a public URL to access a file.

Getting started

Start by adding this plugin to your dependencies using Compose:

composer require thib92/flysystem-public-url-plugin

Then, add the plugin to your Flysystem filesystem:

<?php
$adapter = new \League\Flysystem\Adapter\Local(__DIR__.'/path/to/root/');
$filesystem = new \League\Flysystem\Filesystem($adapter);
$filesystem->addPlugin(new \Thib\FlysystemPublicUrlPlugin\PublicUrlPlugin);

Finally, use it as a regular Flysystem plugin:

<?php
$filesystem->getPublicUrl("/path/to/my/file");

Supported adapters

The supported Flysystem adapters are:

• Local : LocalUrlAdapter
• AWS S3 v3 : LocalUrlAdapter

Adapters options

Some adapters need options. For example, the Local Flysystem does not know if the upload directory is served by a webserver.

In order to set settings, you can use the setParam method of the PublicUrlPlugin. For example:

<?php
$plugin = new \Thib\FlysystemPublicUrlPlugin\PublicUrlPlugin();
$plugin->setParam(\Thib\FlysystemPublicUrlPlugin\Adapter\LocalUrlAdapter::class, [
    "/path/to/webserver/root"
]);

The first argument of setParam is the class of the PublicUrlAdapter you use.
The second one is a sequential array of constructor arguments for this adapter. Refer to the individual adapter documentations below to know what to set

Adapters reference

Adding your own adapter

If you need an adapter for another Flysystem adapter, two steps are required:

1. Create your Adapter class

Your Adapter class will need to extend the AbstractPublicUrlAdapter. You will directly get a reference to the filesystem instance with $this->filesystem. You will need to implement the getPublicUrl(string $path): string method.

2. Register it in the plugin

Then you need to use the PublicUrlPlugin::addAdapter method to register your adapter. This method takes 3 arguments:

• The Flysystem adapter class that your PublicUrlAdapter works for
• Your PublicUrlAdapter class (the plugin will create a new instance on every call to getPublicUrl())
• Optional: an array of constructor arguments, see Adapter Options

Contributing

I only created this plugin for the needs of a project I had. I only used the AWS S3 and the Local adapters. Therefore, if you create an adapter, feel free to create a PR on this repo with your code. Don't forget to add tests:

• Unit tests in the tests/Adapter folder
• Integration tests in tests/PublicUrlPluginTest file for an integration test to the plugin
