ABSPATH is a PHP constant, which holds the Absolute path to the WordPress directory.
It is defined in wp-config.php
1 2 3 4 | /** Absolute path to the WordPress directory. */if ( ! defined( 'ABSPATH' ) ) { define( 'ABSPATH', __DIR__ . '/' );} |
ABSPATH for Security
You can place it on top of a plugin or theme to prevent direct access to these files (from the URL):
1 2 3 4 | // Exit if accessed directly.if ( ! defined( 'ABSPATH' ) ) { exit;} |
