Submenu disappearing when clicked in the submenu in wordpress(在 wordpress 的子菜单中单击时子菜单消失)

本文介绍了在 wordpress 的子菜单中单击时子菜单消失的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

这是我为 wordpress 主题中的菜单和子菜单编写的服装功能，但是在我测试之后，当我单击子菜单时，子菜单消失了，因为 wordpress 没有将类别与子类别分开，因此它们是cat"，这意味着当我点击一个子菜单时，创建子菜单的函数会检查 url 中的 cat=id 是否有子类别，但它没有，因为它是一个子类别，我是 wordpress 的新手我不知道如何处理这个:

Here are my costume functions that I wrote for the menu and submenu in my wordpress theme, but after I tested it the submenu disappeared when I clicked on a submenu, because wordpress doesn't separate categories from subcategories, so the parameter for them is "cat", which means that when I click on a submenu then the function that creates the submenu checks if cat=id in the url has child categories but it doesn't because it is a child category, I am new into wordpress and I don't know how to deal with this:

function costume_menu() {
$categories =  get_categories('hide_empty=0&style=none&parent=0'); 
  foreach ($categories as $category) {
    (is_category($category->term_id)) ? $active = 'class="active_menu"' : $active = '';
    $nav = '<li>';
    $nav .= '<a '.$active.'href="'.get_category_link($category->term_id).'">'.strtoupper($category->cat_name).'</a>';
    $nav .= '</li>';

    echo $nav;
  }

}

function costume_submenu($cat) {

$categories =  get_categories("child_of=$cat&hide_empty=0"); 
  foreach ($categories as $category) {
    (is_category($category->term_id)) ? $active = 'class="active_menu"' : $active = '';
    $nav = '<li>';
    $nav .= '<a '.$active.'href="'.get_category_link($category->term_id).'">'.strtoupper($category->cat_name).'</a>';
    $nav .= '</li>';

    echo $nav;
  }
}
