通过自定义分类法类型迭代自定义帖子类型？ （按类别排序wordpress帖子，或按分类学术语显示自定义帖子类型）

  Jeez，一旦你发现自定义分类法的每个项目都被称为一个术语（在nopress的wordpress docs中并不是很明显），它的搜索就更加简单了 . 没有所有自定义查询内容，此解决方案更容易理解 .

  <?php
  // A term is an item of a taxonomy (e.g. "Promotional" could be a term for the taxonomy "video_type")
  // ...so $categories could be $terms and it would still make sense
  $categories = get_terms('taxonomy_name');
  foreach( $categories as $category ):
  ?>
    <section class="category-<?php echo $category ?>">
      <h2><?php echo $category->name; // Print the cat title ?></h2>
      <p class="description"><?php echo $category->description ?></p>
      <div class="<?php echo $category->post_type ?>-list">
        <?php
        //select posts in this category (term), and of a specified content type (post type) 
        $posts = get_posts(array(
          'post_type' => 'custom_post_type_name',
          'taxonomy' => $category->taxonomy,
          'term' => $category->slug,
          'nopaging' => true, // to show all posts in this category, could also use 'numberposts' => -1 instead
        ));
        foreach($posts as $post): // begin cycle through posts of this category
          setup_postdata($post); //set up post data for use in the loop (enables the_title(), etc without specifying a post ID)
        ?>
          // Now you can do things with the post and display it, like so
          <article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
            <h3><?php the_title(); ?></h3>
            <?php 
              // Getting custom field data example
              echo get_post_meta($post->ID, 'field_key', true); 
            ?>
            <?php the_content() ?>
          </article>
        <?php endforeach; ?>
      </div>
    </section>
  <?php endforeach; ?>
  

  然后，通过在wordpress codex中搜索上述函数，可以填补理解上的任何空白 . 在上面的代码中，对于我的特定应用程序，custom_post_type_name将是video，而taxonomy_name将是video_type（或者video_types，我忘了） .

  你可以尝试另一种方法 . 尝试使用get_posts按照自定义分类法对您的帖子进行排序，设置一个最初为空字符串的变量（称为$ current_cat或其他），并对结果的每个循环进行检查，检查分类并将其与$ current_cat进行比较 - 如果不同的是，打印出新类别的 Headers 然后输入，如果相同，则像往常一样打印输入 .

  您的代码的一个明显问题（我相信）是您没有正确查询自定义分类 . 您应该在查询中使用 taxonomy_name => 'value' ，查询中的 cat 不会触及自定义分类 .

  如果您需要更多细节，请与我们联系 .

  编辑：更多细节！

  // get a list of categories, in this case your custom taxonomy (your_taxonomy_name)
  $querystr = "SELECT terms.* FROM $wpdb->term_taxonomy tax LEFT JOIN $wpdb->terms terms ON tax.term_id = terms.term_id WHERE tax.taxonomy = 'your_taxonomy_name'";
  
  $categories = $wpdb->get_results($querystr, OBJECT);
  
  foreach( $categories as $category ): // begin a loop through those terms (categories in your custom taxonomy)
      echo '<div class="category-header"><h3>'.$category->name.'</h3>'; // print the cat title
      echo '<p class="category-description">'.strip_tags(term_description($category->term_id,'your_taxonomy_name')).'</p></div>'; // cat description
  
      $posts = get_posts( array( 'your_taxonomy_name' => $category->name, 'post_type' => 'your_post_type' ) ) //select posts in this category, and of a specified content type
      foreach($posts as $post) : // begin cycle through posts of this category
          setup_postdata($post); //set up post data for use in the loop (enables the_title(), etc without specifying a post ID)
  
          [ ... ] // do things with your post (display it)
  
      endforeach;
  
  endforeach;
  

  应该这样做 - 而this可能有助于使用get_posts .
