Question

我想在前端的所有woocommerce類的，像這樣的結果子類別：

<ul> 
    <li><a href="">Link</a> 
     <ul> 
      <li><a href="">Submenu link</a></li> 
     </ul> 
    </li> 
</ul> 

這裏是我有（但它不是我想要的）：

<?php 

    $taxonomy  = 'product_cat'; 
    $orderby  = 'name'; 
    $show_count = 0;  // 1 for yes, 0 for no 
    $pad_counts = 0;  // 1 for yes, 0 for no 
    $hierarchical = 1;  // 1 for yes, 0 for no 
    $title  = ''; 
    $empty  = 0; 

    $args = array(
     'taxonomy'  => $taxonomy, 
     'orderby'  => $orderby, 
     'show_count' => $show_count, 
     'pad_counts' => $pad_counts, 
     'hierarchical' => $hierarchical, 
     'title_li'  => $title, 
     'hide_empty' => $empty 
); 
$all_categories = get_categories($args); 
foreach ($all_categories as $cat) { 
    if($cat->category_parent == 0) { 
     $category_id = $cat->term_id;  
     echo '<li><a href="'. get_term_link($cat->slug, 'product_cat') .'">'. $cat->name .'</a></li>'; 

     $args2 = array(
       'taxonomy'  => $taxonomy, 
       'child_of'  => 0, 
       'parent'  => $category_id, 
       'orderby'  => $orderby, 
       'show_count' => $show_count, 
       'pad_counts' => $pad_counts, 
       'hierarchical' => $hierarchical, 
       'title_li'  => $title, 
       'hide_empty' => $empty 
     ); 
     $sub_cats = get_categories($args2); 
      if($sub_cats) { 
       foreach($sub_cats as $sub_category) { 
        echo '<li><a href="'. get_term_link($sub_category->slug, 'product_cat') .'">'. $sub_category->name .'</a></li>'; 
       } 
      } 
     }  
} 
?> 

這段代碼顯示的類別和子類別，但子類不應該放在這裏，子類是像這樣的單獨鏈接：

<ul> 
    <li><a href="">link</a></li> 
    <li><a href="">Submenu link</a></li> 
</ul> 

Answer 1

你可以試試這個代碼：

$args = array(
      'taxonomy' => 'product_cat', 
      'hide_empty' => false, 
      'parent' => 0 
    ); 
    $product_cat = get_terms($args); 

    foreach ($product_cat as $parent_product_cat) 
    { 

    echo ' 
     <ul> 
     <li><a href="'.get_term_link($parent_product_cat->term_id).'">'.$parent_product_cat->name.'</a> 
     <ul> 
      '; 
    $child_args = array(
       'taxonomy' => 'product_cat', 
       'hide_empty' => false, 
       'parent' => $parent_product_cat->term_id 
     ); 
    $child_product_cats = get_terms($child_args); 
    foreach ($child_product_cats as $child_product_cat) 
    { 
    echo '<li><a href="'.get_term_link($child_product_cat->term_id).'">'.$child_product_cat->name.'</a></li>'; 
    } 

    echo '</ul> 
     </li> 
    </ul>'; 
    } 

這將在您的WooCommerce，基於WordPress站點打印。
