[记录]如何仅自定义某些菜单-WP新手学园

作为一个记录，感觉以后可能会需要用到

function wpse_218377_nav_menu_css_class( $classes, $item, $args ) {
    if ( ! empty( $args->theme_location ) && $args->theme_location === 'custom-menu' ) {
        $classes[] = 'footer--menu-item';
    }

    // ALWAYS return, not from inside the if
    return $classes;
}

add_filter( 'nav_menu_css_class' , 'wpse_218377_nav_menu_css_class' , 10, 3 );

function wpse_218377_nav_menu_css_class( $classes, $item, $args ) {

if ( ! empty( $args->theme_location ) && $args->theme_location === 'custom-menu' ) {

$classes[] = 'footer--menu-item';

}

// ALWAYS return, not from inside the if

return $classes;

}

add_filter( 'nav_menu_css_class' , 'wpse_218377_nav_menu_css_class' , 10, 3 );
