README

Seamlessly integrate Composer into a standard WordPress installation.

This plugin automatically loads Composer’s vendor/autoload.php (via an automatically generated must-use (MU) plugin), so any Composer-installed libraries are available without modifying WordPress core, themes, plugins or restructuring directories.

Key features:

• Drop-in solution for stock WordPress installs
• No changes to wp-config.php or core files
• Fully automatic Composer autoloader inclusion
• Works with themes, plugins, or custom PHP libraries managed via Composer

Usage:

1. If Composer is not yet used in the project:

   • Initialize Composer in your WordPress root:

     composer init

   • Install any libraries you need, e.g.:

     composer require monolog/monolog

   • Require this plugin:

     composer require wp-plus/composer-autoload

   • Done - all Composer dependencies, including the newly added ones, are automatically available in WordPress.

2. If the project is already using Composer:

   • Require this plugin via Composer:

     composer require wp-plus/composer-autoload

   • Done - your existing Composer dependencies are now autoloaded in WordPress.
   • Optional cleanup: remove any hardcoded require 'vendor/autoload.php' lines from your theme or plugin files, as this plugin handles it automatically.
