我想通过自定义分类id获取自定义帖子，这是我的自定义代码。

function services_custom_init() {
 $labels = array(
   \'name\' => _x(\'services\', \'post type general name\'),
   \'singular_name\' => _x(\'services\', \'post type singular name\'),
   \'add_new\' => _x(\'Add New\', \'services\'),
   \'add_new_item\' => __(\'Add New services\'),
   \'edit_item\' => __(\'Edit services\'),
   \'new_item\' => __(\'New services\'),
   \'all_items\' => __(\'All services\'),
   \'view_item\' => __(\'View services\'),
   \'search_items\' => __(\'Search services\'),
   \'not_found\' =>  __(\'No services found\'),
   \'not_found_in_trash\' => __(\'No services found in Trash\'), 
   \'parent_item_colon\' => \'\',
   \'menu_name\' => __(\'Services\')

 );
 $args = array(
   \'labels\' => $labels,
   \'public\' => true,

   \'publicly_queryable\' => true,
   \'show_ui\' => true, 
   \'show_in_menu\' => true, 
   \'query_var\' => true,
   \'rewrite\' => true,
   \'capability_type\' => \'post\',
   \'has_archive\' => true, 
   \'hierarchical\' => false,
   \'menu_position\' => null,
   \'supports\' => array( \'title\', \'editor\', \'author\', \'thumbnail\', \'excerpt\', \'comments\' )
 ); 



 register_post_type(\'services\',$args);
}
add_action( \'init\', \'services_custom_init\' );


//hook into the init action and call create_book_taxonomies when it fires
add_action( \'init\', \'create_myservices_hierarchical_taxonomy\', 0 );
function create_myservices_hierarchical_taxonomy() {


  $labels = array(
    \'name\' => _x( \'myservices\', \'taxonomy general name\' ),
    \'singular_name\' => _x( \'myservices\', \'taxonomy singular name\' ),
    \'search_items\' =>  __( \'Search myservices\' ),
    \'all_items\' => __( \'All myservices\' ),
    \'parent_item\' => __( \'Parent myservices\' ),

    \'menu_name\' => __( \'Myservices\' ),
  );    

// Now register the taxonomy

  register_taxonomy(\'myservices\',array(\'services\'), array(
    \'hierarchical\' => true,
    \'labels\' => $labels,
    \'show_ui\' => true,
    \'show_admin_column\' => true,
    \'query_var\' => true,
    \'rewrite\' => array( \'slug\' => \'services\' ),
  ));

} 

<?php $custom_terms = get_terms(\'myservices\');

foreach($custom_terms as $custom_term) {
    wp_reset_query();
    $args = array(\'post_type\' => \'services\',
        \'tax_query\' => array(
            array(
                \'taxonomy\' => \'myservices\',
                \'field\' => \'slug\',
                \'terms\' => $custom_term->slug,
            ),
        ),
     );

     $loop = new WP_Query($args);
     if($loop->have_posts()) {
        echo \'<h2>\'.$custom_term->name.\'</h2>\';

        while($loop->have_posts()) : $loop->the_post();
            echo \'<a href="\'.get_permalink().\'">\'.get_the_title().\'</a>\';

       <?php  endwhile; ?>
     }
}
?>
