register_nav_menus() WordPress Function

The register_nav_menus() function is used to create custom menus for your website. This function takes two arguments: the first is the name of the menu, and the second is an array of menu items. To use this function, first create a custom menu in your Wordpress admin panel. Then, add the following code to your theme's functions.php file: __( 'Main Menu' ), 'secondary-menu' => __( 'Secondary Menu' ), ) ); ?> This code will register two custom menus: "Main Menu" and "Secondary Menu". You can then use these menus in your theme by calling the wp_nav_menu() function.

register_nav_menus( string[] $locations = array() ) #

function register_nav_menus( $locations = array() ) {
	global $_wp_registered_nav_menus;

	add_theme_support( 'menus' );

	foreach ( $locations as $key => $value ) {
		if ( is_int( $key ) ) {
			_doing_it_wrong( __FUNCTION__, __( 'Nav menu locations must be strings.' ), '5.3.0' );
			break;
		}
	}

	$_wp_registered_nav_menus = array_merge( (array) $_wp_registered_nav_menus, $locations );
}
