WordPress MailHog MU Plugin

WordPress Mailhog MU Plugin. Designed to be used in tandem with docker-compose.

Install it as a dev dependency:

composer require awps/wp-mailhog-mu-plugin --dev

Add the instructions for plugin location:

Note: Replace .srv/wordpress/ with the path of your WP installation.

"extra": {
    "installer-paths": {
      ".srv/wordpress/wp-content/mu-plugins/{$name}/": [ "type:wordpress-muplugin"]
    }
},

Add the Mailhog configuration in docker-compose.yml

version: '3'
services:
    # ... other services
    mailhog:
        image: mailhog/mailhog
        ports:
            - 1025:1025 # smtp server
            - 8025:8025 # web ui

Lastly, add the loader inside of mu-plugins.

By default, MU Plugins can't be loaded from folders, they must be one single file. Hopefully we can trick the system by loading all plugins that follow a simple pattern. See this gist for details. https://gist.github.com/awps/9d9d97ef743d78f32f10ca78d2ba1746

Save this code in a file and place it inside mu-plugins dir.

<?php
$flags = \FilesystemIterator::KEY_AS_PATHNAME | \FilesystemIterator::SKIP_DOTS;
$iterator = new \FilesystemIterator(__DIR__, $flags);

foreach ($iterator as $path => $item) {
    if ($item->isDir()) {
        $muPath = trailingslashit($path);
        $fileName = basename($item->getFileName());
        $filePath = "{$muPath}/{$fileName}.php";

        if (file_exists($filePath)) {
            require_once $filePath;
        }
    }
}
