这是我在wordpress主题中为菜单和子菜单编写的服装功能,但在我测试之后,当我点击一个子菜单时子菜单消失了,因为wordpress没有将子类别与子类别分开,所以它们的参数是“cat”,这意味着当我点击一个子菜单然后创建子菜单的函数检查url中的cat = id是否有子类别,但它不是因为它是一个子类别,我是wordpress的新手,我不知道如何处理它:
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;
}
}

尝试这样的功能:
function costume_submenu($cat) {
$current_cat=get_category($cat);
if($current_cat->parent==0)
$parent_cat=$cat;
else
$parent_cat=$current_cat->parent;
$categories = get_categories("child_of=$parent_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;
}
}
