要按类别对其进行细分，需要循环浏览类别列表，然后查询每个类别：

$categories = get_categories( array (\'orderby\' => \'name\', \'order\' => \'asc\' ) );

foreach ($categories as $category) {

   echo "Category is: $category->name <br/>";

   $catPosts = new WP_Query( array ( \'category_name\' => $category->slug, \'orderby\' => \'title\' ) ); 

   if ( $catPosts->have_posts() ) {

       while ( $catPosts->have_posts() ) {
          $catPosts->the_post();
          echo "<a href=\'the_permalink()\'>the_title()</a>";
       }

       echo "<p><a href=\'category/$category->slug\'>More in this category</a></p>";

   } //end if
  


} //end foreach

wp_reset_postdata();

我想你是说GROUP Post 按类别/分类NOT SORT.

这里是一个代码GROUP 通过category/taxonomy

1. $terms = get_terms( \'my_cat_name\' );cat_name name是分类法的名称，当您这样注册它时：例如。

   register_taxonomy( \'my_cat_name\', array( \'custom_post_name\' ), $args )
   

   在中使用它Query e、 g.：

   $args = array(
      \'post_type\'  => \'custom_post_name\',
      \'my_cat_name\' => $term->slug,
      \'posts_per_page\' => $no_of_posts,
   );
   

   完整代码：

   $terms = get_terms( \'CUSTOM_TAXONOMY_SLUG\' );
   
   if ( ! empty( $terms ) && ! is_wp_error( $terms ) ){
   
       $output .= \'<ul class="category-list">\';
       foreach ( $terms as $term ) {
   
           $output .= \'<li class="single-cat">\';
           $output .= \'    <h3>\' . $term->name . \'</h3>\';  //  Taxonomy/Category Name
   
               $args = array(
                   \'post_type\'     => \'POST_TYPE_SLUG\',
                   \'CUSTOM_TAXONOMY_SLUG\' => $term->slug,
                   \'posts_per_page\' => -1,
               );    
   
               $the_query = new WP_Query( $args );
   
               if ( $the_query->have_posts() ) {
                   $output .= \'<ul class="cat-post-list">\';
                   while ( $the_query->have_posts() ) {
                       $the_query->the_post();
                       $output .=\'     <li class="cat-single-post">\';
                       $output .=\'         <h4><a href="\'.get_the_permalink().\'">\' .get_the_title(). \'</a></h4>\';
                       $output .=\'     </li><!-- .cat-single-post -->\';
                   }
                   $output .= \'</ul><!-- .cat-post-list -->\';
               } 
               wp_reset_postdata();
           $output .= \'</li><!-- .single-cat-item -->\';
       }
       $output .= \'</ul><!-- .category-list -->\';
   }
   

扩展Maheshwaghmare的工作；

<? 
$terms = get_terms( \'CUSTOM_TAXONOMY\' );
if ( ! empty( $terms ) ){ ?>

<div class="POST_TYPE_PLURAL">

<?  foreach ( $terms as $term ) {
//print_r($term) // DEBUG;
$term_slug = $term->slug;
$term_name = $term->name;
$term_description = $term->description;
?>

    <div class="POST_TYPE_CATEGORY <?=$term_slug; ?>">

      <h1 class="section-head"> <?=$term_name; ?> </h1>
      <p><?=$term_description; ?> </p>

       <?  
        $args = array(
          \'post_type\'     => \'CUSTOM_POST_TYPE\',
          \'tax_query\' => array(
            array(
              \'taxonomy\' => \'CUSTOM_TAXONOMY\',
              \'field\'    => \'slug\',
              \'terms\'    => $term_slug,
            ),
          ),
           \'posts_per_page\' => -1,
         );    

         $the_query = new WP_Query( $args );

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

               <div class="POST_TYPE_SINGLE">
                <h3> <? the_title(); ?> </h3>
                <? // MORE TEMPLATING CODE ?>
               </div>

             <?  endwhile;
           endif;
           wp_reset_postdata(); ?>
     </div>
 <?  } // foreach
 } //if terms
 ?>

您可以使用orderby 新的wp_query 实例：

$query = new WP_Query( array ( \'orderby\' => \'title\', \'order\' => \'DESC\' ) );
