How to add ACF PRO to your WordPress project using Composer
Advanced Custom Fields PRO (ACF PRO) is a powerful tool for extending WordPress capabilities. In this article, we’ll show you how to integrate ACF PRO into your WordPress project using Composer, configure your license using a JSON file, and hide the ACF admin interface so fields can only be created via code.
Configure Composer
First, make sure you have Composer installed on your system. You can download it from getcomposer.org.
Generate API credentials
1. Go to your ACF account, under the licenses tab, and generate an auth.json
file with your API credentials.
2. The file should have the following format:
{ "http-basic": { "connect.advancedcustomfields.com": { "username": "YOUR_LICENSE_KEY_HERE", "password": "https://yoursite.com" } } }
Configure Composer
Add the ACF repository to your composer.json
file:
{ "repositories": [ { "type": "composer", "url": "https://connect.advancedcustomfields.com" } ], "require": { "wpengine/advanced-custom-fields-pro": "^6.0" } }
Include the plugin in your project
Composer will not automatically include the plugin in your project, so you need to manually include it in your functions.php
or your custom plugin:
<?php require_once __DIR__ . '/vendor/wpengine/advanced-custom-fields-pro/acf.php';
Hide the ACF admin
To ensure fields can only be created via code and not through the graphical interface, add the following code to your functions.php
or custom plugin:
<?php add_filter('acf/settings/show_admin', '__return_false');
Create fields via code
You can create your fields using the acf_add_local_field_group()
function. Here’s an example of how to do it:
<?php if( function_exists('acf_add_local_field_group') ): acf_add_local_field_group(array ( 'key' => 'group_1', 'title' => 'Custom Fields Group', 'fields' => array ( array ( 'key' => 'field_1', 'label' => 'Custom Field', 'name' => 'custom_field', 'type' => 'text', ), ), 'location' => array ( array ( array ( 'param' => 'post_type', 'operator' => '==', 'value' => 'post', ), ), ), )); endif;
By following these steps, you will have integrated ACF PRO into your WordPress project using Composer, configured your license via a JSON file, and hidden the ACF admin interface so that fields can only be created via code. This will allow you to maintain stricter control over custom fields and improve the management of your project.
