在wordpress中,以下函數將回顯一個類別列表,其中每個類別名稱下面的每個類別都有關聯的職位。WordPress的 - 列出每個類別下的職位類別的層次結構

這工作正常,除了這會產生一個平面結構的事實。有些類別是兒童類別的其他類別,我希望能夠輸出與此匹配的結構的列表(有點像網站地圖)

是否有人能夠幫助我弄清楚如何修改此代碼以實現此目的?

function posts_by_category() { 

//get all categories then display all posts in each term 
$taxonomy = 'category'; 
$param_type = 'category__in'; 
$term_args=array(
    'orderby' => 'name', 
    'order' => 'ASC' 
); 
$terms = get_terms($taxonomy,$term_args); 
if ($terms) { 
    foreach($terms as $term) { 
    $args=array(
     "$param_type" => array($term->term_id), 
     'post_type' => 'post', 
     'post_status' => 'publish', 
     'posts_per_page' => -1, 
     'caller_get_posts'=> 1 
     ); 
    $my_query = null; 
    $my_query = new WP_Query($args); 
    if($my_query->have_posts()) { ?> 
     <div class="category section"> 
     <h3><?php echo ''.$term->name;?></h3> 
      <ul> 
       <?php while ($my_query->have_posts()) : $my_query->the_post(); ?> 
        <li><a href="<?php the_permalink() ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></li> 
       <?php endwhile; ?> 
      </ul> 
     </div> 
    <?php 
    } 
    } 
} 
wp_reset_query(); // Restore global post data stomped by the_post(). 
}

這是我在前些天找到的代碼片段Hierarchical Category List with Post Titles,應該這樣做。

<?php 
/***************************************************************** 
* 
* alchymyth 2011 
* a hierarchical list of all categories, with linked post titles 
* 
******************************************************************/ 
// http://codex.wordpress.org/Function_Reference/get_categories 

foreach(get_categories('hide_empty=0') as $cat) : 
if(!$cat->parent) { 
echo '<ul><li><strong>' . $cat->name . '</strong></li>'; 
process_cat_tree($cat->term_id); 
} 
endforeach; 

wp_reset_query(); //to reset all trouble done to the original query 
// 
function process_cat_tree($cat) { 

$args = array('category__in' => array($cat), 'numberposts' => -1); 
$cat_posts = get_posts($args); 

if($cat_posts) : 
foreach($cat_posts as $post) : 
echo '<li>'; 
echo '<a href="' . get_permalink($post->ID) . '">' . $post->post_title . '</a>'; 
echo '</li>'; 
endforeach; 
endif; 

$next = get_categories('hide_empty=0&parent=' . $cat); 

if($next) : 
foreach($next as $cat) : 
echo '<ul><li><strong>' . $cat->name . '</strong></li>'; 
process_cat_tree($cat->term_id); 
endforeach; 
endif; 

echo '</ul>'; 
} 
?>
