Question

我有代码，显示所有子类别。但我需要只显示第一级，而在第二级显示产品

 1. Category
    1.1 First-level
       1.1.1 Second level

代码：

$second_level_cats = get_term_children($cat->term_id, $cat->taxonomy); 
foreach ($second_level_cats as $second_level_cat_id) :
    if(!get_term_children($cat_id, $cat->taxonomy)) :
        $second_level_cat = get_term($second_level_cat_id, $cat->taxonomy); 
    endif; 
endforeach;

Answer 1

您可以使用以下代码获取父猫：

<?php
$cat_id = get_query_var('cat');
$args=array(
            'parent' => $cat_id,
            'hide_empty' => 0,
            'orderby' => 'name',
            'order' => 'ASC'
        );
