我有这个问题：

$cat_array = array();
    $args=array(
      \'post_type\' => \'post\',
      \'post_status\' => \'publish\',
      \'exclude\' => \'187\',
      \'posts_per_page\' => 19,
      \'caller_get_posts\'=> 1
      );
    $my_query = null;
    $my_query = new WP_Query($args);
    if( $my_query->have_posts() ) {
      while ($my_query->have_posts()) : $my_query->the_post();
        $cat_args=array(\'orderby\' => \'none\');
        $cats = wp_get_post_terms( $post->ID , \'category\', $cat_args);
        foreach($cats as $cat) {
          $cat_array[$cat->term_id] = $cat->term_id;
        }
      endwhile;
    }
    if ($cat_array) {
      foreach($cat_array as $cat) {
        $category = get_term_by(\'ID\',$cat, \'category\');
        echo \'<li><a href="\' . esc_attr(get_term_link($category, \'category\')) . \'" title="\' . sprintf( __( "View latest posts in %s" ), $category->name ) . \'" \' . \'>\' . $category->name.\'</a>\'.\'</li>\';
      }
    }
    wp_reset_query();

其中列出了最新更新的类别。一切都很好。但我想从那里的列表中排除一个特定类别。这可以像我在查询中一样完成\'exclude\' => \'187\', 但问题在于以下示例：我有一篇文章属于两个类别，一个类别是我不想显示的类别，另一个类别是我想显示的类别。如果我像上面所说的那样简单地排除它，那么列表中不会显示任何类别，因为它将完全排除该帖子。我怎样才能显示其他类别，并隐藏我不想显示的类别？

有什么线索吗？

谢谢

 if ($cat_array) {
      foreach($cat_array as $cat) {
        $category = get_term_by(\'ID\',$cat, \'category\');
     if($category->name != \'Excluded category\'){
        echo \'<div class="catspace"><a href="\' . esc_attr(get_term_link($category, \'category\')) . \'" title="\' . sprintf( __( "latest posts %s" ), $category->name ) . \'" \' . \'>\' . $category->name.\'</a>\'.\'</div>\';
     }else{echo \'<div class="catspace">\'. \'\'   .\'</div>\';    }
     }
   }

foreach ( $cat_array as $cat ) {
    if ( $cat != EXCLUDED_CAT_ID ) {
        // Output
    }
}
