所以我刚刚在学习和玩定制步行器，我发现这非常有用Stack Overflow question. 因此，我实现了该答案中的答案，并将其添加到我的函数中。我的主题的php（顺便说一句，如果有帮助的话，它是一个下划线主题）

然后，我更改了标题中的wp\\u nav\\u菜单。php收件人：

wp_nav_menu( array( \'theme_location\' => \'primary\', 
\'menu_id\' => \'primary-menu\', \'walker\' => new Custom_Walker_Nav_Menu ) );

问题是HTML现在的结构与我想要的一样，但是当实现自定义walker时，锚定标记会丢失它们之间的文本（这是页面的标题）和它们的href属性，因此它们不再是指向我需要它们访问的页面的链接。

我觉得可能是因为$attributes 阵列，但我不确定如何进行修复。

感谢您的帮助！
