菜单项说明？wp_nav_menu（）的自定义Walker

由于 WordPress 3.0 ,您不需要需要自定义漫游器不再！

有 walker_nav_menu_start_el 过滤器,请参见 https://developer.wordpress.org/reference/hooks/walker_nav_menu_start_el/

示例:

 function add_description_to_menu($item_output, $item, $depth, $args) {
    if (strlen($item->description) > 0 ) {
        // append description after link
        $item_output .= sprintf('<span class="description">%s</span>', esc_html($item->description));

        // insert description as last item *in* link ($input_output ends with "</a>{$args->after}")
        //$item_output = substr($item_output, 0, -strlen("</a>{$args->after}")) . sprintf('<span class="description">%s</span >', esc_html($item->description)) . "</a>{$args->after}";
    }

    return $item_output;
}
add_filter('walker_nav_menu_start_el', 'add_description_to_menu', 10, 4);
 

Since WordPress 3.0, you don't need a custom walker anymore!

There is the walker_nav_menu_start_el filter, see https://developer.wordpress.org/reference/hooks/walker_nav_menu_start_el/

Example:

function add_description_to_menu($item_output, $item, $depth, $args) {
    if (strlen($item->description) > 0 ) {
        // append description after link
        $item_output .= sprintf('<span class="description">%s</span>', esc_html($item->description));

        // insert description as last item *in* link ($input_output ends with "</a>{$args->after}")
        //$item_output = substr($item_output, 0, -strlen("</a>{$args->after}")) . sprintf('<span class="description">%s</span >', esc_html($item->description)) . "</a>{$args->after}";
    }

    return $item_output;
}
add_filter('walker_nav_menu_start_el', 'add_description_to_menu', 10, 4);

这并不比其他建议好或坏；只是不同而已.它又短又甜.

您可以代替在 @toscho 建议的字段中使用"标题"字段每个菜单项都带有所需的文本,然后使用此CSS:

.menu-item a:after { content: attr(title); }

使用jQuery 来附加它也很容易,但是文本的装饰性足以使CSS看起来合适

This isn't better or worse than other suggestions; it's just different. It's short and sweet too.

Rather than using the description field as @toscho suggests, you could fill in the "Title" field on each menu item with the text you want, and then use this CSS:

.menu-item a:after { content: attr(title); }

It would also be easy to use jQuery to append it, but the text is ornamental enough that CSS seems appropriate.

您还可以在菜单中的导航标签之后写入<span>元素,并使用以下CSS规则更改其display设置(即inline默认):

 span {display:block}
 

You can also write a <span> element after the navigation label in menus and use the following CSS rule to change its display setting (it's inline by default):

span {display:block}
