Custom routes in WordPress plugins can significantly enhance your website’s functionality, allowing you to create unique and dynamic interactions with your users. By leveraging the WordPress REST API, you can expose custom endpoints for various purposes, such as communicating with a front-end application, fetching data from external sources, or building a proxy to other services to hide secret access keys.
Implementing the Custom Plugin and JSON API Route
To create our custom plugin, we’ll start by creating a new folder in the
wp-content/plugins directory. Name the folder
custom-api-route. Inside the folder, create a new PHP file called
custom-api-route.php and add the following code to initialize the plugin:
Now, let’s register our custom JSON API route. Since we focus on the specific custom route and function, we’ll keep it simple and avoid using PHP classes or any other boilerplate code.
This code snippet registers a new POST route at
process_data_submission function will handle the submitted data.
This function takes a
WP_REST_Request object as an argument and processes the submitted data accordingly. In this example, we return a successful response with a status message, but you can modify this function to process the data as needed.
This script will execute immediately after the DOM is ready, sending a POST request to our custom route with some example data. The result of the function is printed to the console.
Next, we need to enqueue this script in our WordPress plugin. Update the
custom-api-route.php file to include the following function to enqueue the script:
This article shows how to create a custom WordPress plugin with a custom JSON API route. By following this straightforward process, you can quickly and efficiently implement custom routes in your WordPress plugins to extend your website’s functionality.
