MU Plugin Installer

This is a Composer plugin that installs mu plugins into the wp-content/mu-plugins directory. This differs from other solutions as each mu-plugin has it's own dedicated entrypoint file. This means that mu-plugins screen in WordPress has a more accurate representation of which plugins are installed and at what version they are running.

Installation

You can install this package as part of your mu-plugin's composer.json file.

composer require creode/mu-plugin-installer

Usage

Add the following to your composer.json file of your mu-plugin:

{
    "extra": {
        "wordpress-muplugin-entry": "{an-entrypoint-file-name}.php"
    }
}

Supported Package Types

• wordpress-muplugin

Available Placeholders

• :PLUGIN_VERSION: - The version of the plugin which will be pulled in dynamically from composer at install time.

Example

Below is an example of a mu-plugin entrypoint file that will be installed into the wp-content/mu-plugins directory. This demonstrates the use of the :PLUGIN_VERSION: placeholder.

/**
 * Plugin Name: WordPress Blocks
 * Description: WordPress Blocks plugin used by Creode to assist in the development of WordPress blocks.
 * Version: :PLUGIN_VERSION:
 *
 * @package Creode Blocks
 */

// This is a loader for the plugin from the parent directory to handle MU Plugin installation.
require_once __DIR__ . '/wordpress-blocks/plugin.php';

The above example will install the plugin into the wp-content/mu-plugins directory and create a file called wordpress-blocks.php in the wp-content/mu-plugins directory. The file will contain the following content:

/**
 * Plugin Name: WordPress Blocks
 * Description: WordPress Blocks plugin used by Creode to assist in the development of WordPress blocks.
 * Version: 1.9.0
 *
 * @package Creode Blocks
 */

// This is a loader for the plugin from the parent directory to handle MU Plugin installation.
require_once __DIR__ . '/wordpress-blocks/plugin.php';
