WordPress的模板 - 顯示由子類別分離的父類別下的所有帖子

Question

我想創建一個類別模板，顯示每個子類別下的父類別標題，子類別標題和所有帖子。

所以它看起來像這樣

家長 子目錄 帖子＃1 帖子＃2 子目錄 帖子＃3 帖子＃4

這是我有這麼遠，但我堅持如何前進。

<?php if (have_posts()) : ?> 

      <div class="section-header"> 
       <h1 class="page-title"><?php single_cat_title(''); ?></h1> 
       <!-- <?php 
        the_archive_title('<h1 class="page-title">', '</h1>'); 
        the_archive_description('<div class="taxonomy-description">', '</div>'); 
       ?> --> 
      </header><!-- .page-header --> 
      <p>Some text</p> 

       <?php 

        // The Query 
        $the_query = new WP_Query(array('cat' => 72)); 

        // The Loop 
        if ($the_query->have_posts()) { 
         echo '<ul>'; 
         while ($the_query->have_posts()) { 
          $the_query->the_post(); 
          echo '<li>' . get_the_title() . '</li>'; 
         } 
         echo '</ul>'; 
         /* Restore original Post Data */ 
         wp_reset_postdata(); 
        } else { 
        // no posts found 
        } 

        ?> 


     <?php else : ?> 

      <?php ?> 

     <?php endif; ?>

在你的主題的functions.php

function display_category_posts($cat_id) { 
    echo get_cat_name($cat_id); 
    $the_query = new WP_Query(array('cat' => $cat_id)); 
    // you loop code 
    wp_reset_query(); //or wp_reset_postdata(), not put it in have_posts() block, we should always reset query even there no posts found. 
} 

在您的類別模板

// get current category of viewing page. 
$current_cat_obj = get_queried_object(); 

// try to get sub categories. 
$sub_cat_ids = get_terms('category', array(
    'parent' => $current_cat_obj->term_id, 
    'hide_empty' => false, 
    'fields' => 'ids' 
)); 

// if the category of current page is a top-level category and has sub categories, display is as sub category posts view. 
if(!$current_cat_obj->parent && !empty($sub_cat_ids)) { 
    foreach($sub_cat_ids as $sub_cat_id) { 
     display_category_posts($sub_cat_id); 
    } 
} else { 
    // otherwise, display it as normal category view. 
}
