将div插入wp_nav_menu

问题描述

我正在尝试在WordPress中的导航菜单中添加一个div.wp_nav_menu加载所有菜单项，但我不知道如何将div添加到结构中.我的目标是在菜单项悬停时弹出一个子菜单，并在该子菜单块的顶部放置一个箭头图像，使其看起来像一个方形的文本气球.我知道如何在需要的地方以及所有内容中获取它，但不知道如何在其中获取div.

I'm trying to add a div to my navigation menu in wordpress. wp_nav_menu loads all menu items but I have no idea how to add a div into the structure. My goal is to have a submenu pop up on menu-item hover, and to have an arrow image on top of the submenu block to make it look like a square text-balloon. I know how to get it where I want it and everything, but not how to get the div in there.

现在，看起来像这样

<ul class="menu">
 <li>
  <a>
   <ul class="submenu">
    <li>
     <a>

我希望它看起来像这样

<ul class="menu">
 <li>
  <a>
   <ul class="submenu">
    <div class="pointer">
     <li>
      <a>

我该如何实现?

推荐答案

您最好的选择是使用Walker Class.将此添加到您的functions.php文件中:

Your best bet would be to use a Walker Class. Add this in your functions.php file:

class Walker_Nav_Pointers extends Walker_Nav_Menu
{
    function start_lvl( &$output, $depth = 0, $args = array() )
    {
        $indent = str_repeat("\t", $depth);
        $output .= "\n$indent<ul class=\"sub-menu\">\n";
        $output .= "\n<div class=\"pointer\">\n";
    }
    function end_lvl( &$output, $depth = 0, $args = array() )
    {
        $indent = str_repeat("\t", $depth);
        $output .= "$indent</ul>\n".($depth ? "$indent</div>\n" : "");
    }
}

然后在调用导航菜单的任何位置，将其添加到现有参数中:

And then wherever you're calling your nav menu, add this to the existing arguments:

<?php
$navArgs = array('walker' => new Walker_Nav_Pointers());
wp_nav_menu($navArgs);
?>

上面的示例未经测试，我不能保证它可以直接运行，但是应该可以帮助您入门.

The above example is untested and I can't guarantee it will work straight out of the gate, but it should get you started.
