如何在自定义页面上输出自定义帖子类型标题，旁边有类别？

我有一个组织的网站，我为领导团队创建了一个新页面。我运行了一个查询，查找；“成员”-类别为“的类型”；领导力；。到目前为止，当我将此输出到页面上时，效果很好。我还有子类别；“总裁”；和；“秘书”；我想显示在每个领导的名字旁边。但是，我一打电话get_the_category(), 一切都变得一团糟，只有一个结果是输出，总统类别不知何故消失了，职位类别为；“总裁”；获取；“秘书”；显示在其旁边。这是相关代码：

<?php
    $leaderQuery = new WP_Query(array(
        \'posts_per_page\' => -1,
        \'post_type\' => \'member\',
        \'cat_slug\' => "Leadership"
    ));
    
    //var_dump($leaderQuery);
    
    while($leaderQuery->have_posts())
    {
        $postCategories = get_the_category($leaderQuery->the_post());
        //$categoryDescription = category_description($postCategories[0]);
        //var_dump($postCategories);
                $leaderQuery->the_post(); ?>
                <div class="post-item">
                    <p class="headline headline--small"><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a> - <?php echo get_the_category($leaderQuery->the_post())->name; ?></p>
                </div>
            <?php
    }
    wp_reset_postdata();
    echo paginate_links();
  ?>

var_dump($leaderQuery->the_post()) 不包含类别信息，但var_dump($postCategories) 做这是var_dump($postCategories):

array (size=2)
  0 => 
    object(WP_Term)[1446]
      public \'term_id\' => int 7
      public \'name\' => string \'Joint Secretary\' (length=15)
      public \'slug\' => string \'joint-secretary\' (length=15)
      public \'term_group\' => int 0
      public \'term_taxonomy_id\' => int 7
      public \'taxonomy\' => string \'category\' (length=8)
      public \'description\' => string \'B\' (length=1)
      public \'parent\' => int 6
      public \'count\' => int 1
      public \'filter\' => string \'raw\' (length=3)
      public \'cat_ID\' => int 7
      public \'category_count\' => int 1
      public \'category_description\' => string \'B\' (length=1)
      public \'cat_name\' => string \'Joint Secretary\' (length=15)
      public \'category_nicename\' => string \'joint-secretary\' (length=15)
      public \'category_parent\' => int 6
  1 => 
    object(WP_Term)[1441]
      public \'term_id\' => int 6
      public \'name\' => string \'Leadership\' (length=10)
      public \'slug\' => string \'leadership\' (length=10)
      public \'term_group\' => int 0
      public \'term_taxonomy_id\' => int 6
      public \'taxonomy\' => string \'category\' (length=8)
      public \'description\' => string \'\' (length=0)
      public \'parent\' => int 0
      public \'count\' => int 2
      public \'filter\' => string \'raw\' (length=3)
      public \'cat_ID\' => int 6
      public \'category_count\' => int 2
      public \'category_description\' => string \'\' (length=0)
      public \'cat_name\' => string \'Leadership\' (length=10)
      public \'category_nicename\' => string \'leadership\' (length=10)
      public \'category_parent\' => int 0

这是页面上实际输出的当前帖子的错误数据，在这两个帖子中，只有一个显示出来，另一个给出了其类别信息。

如何使每个帖子正确检索类别名称并将其显示在帖子标题旁边？

// Get all categories (term objects) assigned to the current post. $postCategories = get_the_category(); // Get the first category\'s name. $first_cat_name = ( ! empty( $postCategories ) ) ? $postCategories[0]->name : \'\';

if ( in_category( \'Leadership\' ) ) { echo \'In the Leadership category\'; } // Or after closing the PHP tag ( ?> ): //<?php echo in_category( \'Leadership\' ) ? \'In the Leadership category\' : \'\'; ?>

扩展WooCommerce小部件类-WC_Widget_Product_Categories

我正在尝试扩展woocommerce类，该类用于在我自己的插件中创建产品类别小部件，该插件为woo commerce产品添加了一个称为“部门”的新分类法。当我扩展WP\\u小部件时，一切正常，我看到一个新的小部件，可以添加到外观->小部件中。然而，当我试图扩展WC\\u Widget或WC\\u Widget\\u Product\\u类别时，我根本看不到新的Widget，即使我没有收到任何php错误。以下是我所拥有的不起作用的东西：//get the base classes if(!cl
