    I am new in wordpress development. Tried include a selfwritten php-file into htdocs/wp-content/plugins/abc/abc.php

    IDE sugesting me to use: require_once '../WPNonce/WPNonce.php';

    but WordPress contradicts when opening in webbrowser:

    Fatal error: require_once(): Failed opening required '../WPNonce/WPNonce.php'

    How could i include this php-file (its a class inside)?

    • Is the file you want to include part of your plugin? – Qaisar Feroz Commented Mar 3, 2019 at 20:36

    WordPress includes many functions for determining paths and URLs to files or directories within plugins, themes, and WordPress itself. 

     $plugin_dir = plugin_dir_path( __DIR__ ); // wp-content/plugins/
 require_once($plugin_dir.'WPNonce/WPNonce.php');

    While using plugin_dir_path(), keep in mind that the “plugin” part of the name is misleading – it can be used for any file, and will not return the directory of a plugin unless you call it within a file in the plugin’s base directory.

    or alternatively, you can also use WordPress constant WP_PLUGIN_DIR 

     require_once(WP_PLUGIN_DIR.'/WPNonce/WPNonce.php');

    I hope this helps.
