在Wordpress中列出所有帖子和相應的分類標準

Question

我必須列出來自Wordpress自定義帖子類型的所有帖子，並只顯示通過自定義分類標準創建的標題及其各自的類別。我的代碼在這裏，我在分類法上遇到了一些問題。

<?php 
$args = array(
    'post_type' => 'books', 
    'posts_per_page' => -1); 
$myposts = get_posts($args); 
$terms = get_the_terms($post->ID , 'category'); 
foreach ($myposts as $post) : setup_postdata($post); ?> 
    <h1><?php echo the_title(); ?></h1> 
    <p>Category: <?php echo $term->name; ?></p> 
<?php endforeach; 
wp_reset_postdata();?> 

Answer 1

這是你更新的代碼，試試這個：

<?php 
$args = array(
    'post_type' => 'books', 
    'posts_per_page' => -1); 
$myposts = get_posts($args); 
$terms = get_the_terms($post->ID , 'category'); 
foreach ($myposts as $post) : setup_postdata($post); ?> 
    <h1><?php echo the_title(); ?></h1> 
    <?php $categories = get_the_category($post->ID); ?> 
    <?php if(! empty($categories)): ?> 
     <?php foreach($categories as $category): ?> 
      <p>Category: <?php echo $category->name; ?></p> 
      <?php break; ?> 
     <?php endforeach; ?> 
    <?php endif; ?> 
<?php endforeach; 
wp_reset_postdata();?>

<?php $args = array(
      'post_type' => 'books', 
      'posts_per_page' => -1,  
       'tax_query' => array(
      array(
       'taxonomy' => 'category', 
       'field' => 'slug' 

      ), 
     ), 
    ); 
    $myposts = new WP_Query($args); 
    foreach ($myposts as $post) : setup_postdata($post) ?> 
     <h1><?php echo the_title(); ?></h1> 
    <?php $categories = get_the_category(get_the_ID()); ?> 
    <?php if(! empty($categories)): ?> 
     <?php foreach($categories as $category): ?> 
      <p>Category: <?php echo $category->name; ?></p> 
      <?php break; ?> 
     <?php endforeach; ?> 
    <?php endif; ?> 
<?php endforeach; 
wp_reset_postdata();?>

我明白了！謝謝大家！

<?php 
    $terms = get_terms($post_taxonomy); 
    $args = array(
     'post_type' => 'book', 
     'posts_per_page' => -1, 
     'post_taxonomy' => 'category', 
    ); 
    $the_query = new WP_Query($args); 
?> 

<?php if ($the_query->have_posts()) : ?> 
    <?php while ($the_query->have_posts()) : $the_query->the_post(); 

    $category = get_the_terms($post->ID, "category"); 
    $category_name = ""; 
     foreach ($category as $term) { 
      $category_name .= $term->name.' '; 
     } 
    ?> 

    <h1><?php the_title(); ?></h1> 
    <p>Category: <?php echo $category_name; ?></p> 


    <?php endwhile; ?> 
<?php endif; ?>
