你好Wordpress Stack，

我无法将自定义帖子显示在自定义类别下。

所讨论的职位是：

register_post_type(\'feature_article\',
        array(
            \'labels\' => array(/* left out for clarity */),
            \'query_var\' => true,
            \'publicly_queryable\' => true,
            \'exclude_from_search\' => false,
            \'supports\' => array(\'thumbnail\', \'title\', \'excerpt\'),
            \'public\' => true,
            \'has_archive\' => true,
            \'menu_position\' => 5,
            \'taxonomies\' => array(\'twin\')
            )
        );

    add_action( \'init\', \'twin_post_taxonomy\', 0 );

function twin_post_taxonomy() {
    $labels = array(/* for clarity */ );

    $args = array(
        \'hierarchical\'      => true,
        \'labels\'            => $labels,
        \'show_ui\'           => true,
        \'show_admin_column\' => true,
        \'query_var\'         => true,
        \'rewrite\'           => array( \'slug\' => \'twin\' ),
        );

    register_taxonomy( \'twin\', array( \'feature_article\',\'post\'), $args );
}

 <?php $args = array( \'post_type\' => \'feature_article\', \'posts_per_page\' => 1, \'article_genre\' => $str, \'orderby\' => \'modified\');  
   $loop = new WP_Query($args); ?>
 <?php while ( $loop->have_posts() ) : $loop->the_post(); ?>

 <?php if ( in_category(\'double portrait\') ) { 
           echo the_title(); 
  } else { 
           echo the_excerpt(); 
  } ?>

    <?php endwhile;  wp_reset_postdata(); ?>

编辑：我得到的是输出摘录，而不是标题。
