Using Eloquent in WordPress Plugin Development (2025 Edition)

Need to Fix Your WordPress Site?

WordPress is a powerful platform, but when it comes to custom database queries, the $wpdb class often leaves much to be desired. While $wpdb is suitable for straightforward queries, managing complex database operations across multiple tables can quickly become cumbersome and error-prone.

Enter Eloquent, the ORM (Object-Relational Mapper) developed by Laravel, which simplifies database interactions while still allowing the flexibility of raw SQL when needed. In this article, we’ll explore how to set up Eloquent within a WordPress plugin, leveraging its capabilities to build efficient and maintainable database-driven plugins.

Let’s dive in!


Prerequisites

Before we start, ensure you have the following:

  1. A working WordPress installation.
  2. Composer installed globally or locally on your machine. If you’re unfamiliar with Composer, it’s a dependency manager for PHP. Visit Composer’s official page to download and learn more.

Step 1: Set Up the Plugin Directory

Navigate to your WordPress plugins directory:

Create a folder for your plugin. For this guide, we’ll call it eloquent-plugin:

Next, initialize the plugin by creating a main file named eloquent-plugin.php:


Step 2: Install and Configure Eloquent

Install the Eloquent package using Composer:

Your plugin folder should now include a vendor directory, along with composer.json and composer.lock files. Update composer.json to configure autoloading:

Run the following command to regenerate the autoload files:

Create the necessary folder structure:


Step 3: Connect Eloquent to the WordPress Database

Create a file named core/init.php and configure the Eloquent database connection:


Step 4: Create a Model

Define your database model in the app/Models directory. For example, let’s create a model for a clients table:


Step 5: Register a Custom Database Table

Create a file named core/create_db_tables.php to register a custom database table during plugin activation:


Step 6: Create a Controller

Define controller logic in app/Controllers. For example, create an ActionController for AJAX requests:

Register the AJAX actions in core/init.php:


Step 7: Create a Shortcode

Add a shortcode to display the client list. Define it in core/helpers.php:

Create the views/clients.php file:


Conclusion

By integrating Eloquent into WordPress, you can enjoy the power of Laravel’s ORM while still leveraging WordPress’s ecosystem. This setup is especially useful for custom plugins requiring complex database interactions.

However, remember that this approach introduces additional database connections, which can be problematic if multiple plugins adopt similar strategies. Use it wisely for bespoke projects or tightly controlled environments.
