I need to integrate this PHP library on my WordPress site. I read that you have to create a plugin or integrate it into the child theme. So I created a plugin and integrated the PHP library in the plugin folder.


Here is my plugin

Plugin Name: igosen api boxtal
Plugin URI: 
Description: Relier marketplace à boxtal
Author: Serge Astrakhan
Version: 1.0
Author URI: https://igosen.fr/

require_once ('/config/autoload.php');
require_once ('/config/config.php');

The require_once request causes a fatal error when activating the plugin. Can you help me (documentation or example) to be able to correctly load the different elements. Thank you

The / path will try to require the file from your server's root directory. Instead, try something like:

require_once( plugin_dir_path( __FILE__ ) . '/config/autoload.php' );
require_once( plugin_dir_path( __FILE__ ) . 'config/config.php' );
