Fixing "Undefined function" error in VS Code while using the PHP Intelephense for WP development
In this video, I show you how to fix the 'Undefined function...' error in Visual Studio Code (VS Code) when using the PHP Intelephense extension for WordPress development.
This issue arises because the Intelephense extension sometimes fails to recognize WordPress core files, resulting in an 'Undefined function' error for WordPress functions. To resolve this, add the WordPress installation path to the environment's 'Include Path' variable within the Intelephense settings.
To do this, go to 'File - Preferences - Settings', search for 'intelephense', and then add the path to your WordPress directory in the 'Include Path' setting of the Intelephense extension. After saving these settings, restart VS Code to apply the changes.
