Wordpress菜单-指定锚定列表的特定类


wordpress menu - assign specefic class of list to anchor

我想在菜单列表中指定特定的类给它的子锚。

例如:

<li class="icon-home list-item">
    <a href="index.php">Home</a>
</li>

我想把上面的输出转换成这样(从列表中删除类icon-home并将其分配给它的子锚):

<li class="list-item">
    <a class="icon-home" href="index.php">Home</a>
</li>

我想做什么??在wordpress菜单数组中搜索匹配的类icon-,然后将其设置为其子锚,然后从列表中取消设置。

我使用的代码在菜单数组中搜索类divider,然后将其转换为class="除法器"的新列表。下面是代码:

// managing divider: add divider class to an element to get a divider before it.
$divider_class_position = array_search('divider', $classes);
if($divider_class_position !== false){
    $output .= "<li class='"divider'"></li>'n";
    unset($classes[$divider_class_position]);
}

这是我的wordpress菜单覆盖的所有代码,请在回答之前看看:

你必须寻找:

$item_output .= '<a'. $attributes .'>';

并替换为:

$item_output .= '<a'. $attributes .' class="'.$classes[0].'">';

现在它把<li class="icon-home list-item">变成了<a href="index.php" class="icon-home">

在$attributes上只显示链接的活动和悬停效果,没有一个特定的类在链接中定义。
