Show PHP Errors to Administrators With ?debug=1
Lets administrators see PHP warnings and notices on screen by adding ?wpide_debug=1 to any address, while visitors and other users never see them, even with WP_DEBUG_DISPLAY off.
Opens WPIDE on
Code
add_action( 'init', function () {
if ( ! isset( $_GET['wpide_debug'] ) || ! current_user_can( 'manage_options' ) ) {
return;
}
// phpcs:disable WordPress.PHP.IniSet, WordPress.PHP.DevelopmentFunctions
ini_set( 'display_errors', '1' );
error_reporting( E_ALL );
// phpcs:enable
}, 1 );Notes
Errors raised before WordPress knows who is logged in (very early in loading) are not shown; check debug.log for those.
