mysql - 获取除某一类别之外的所有类别的帖子

Question

搜索时，我想要除一个类别之外的所有类别的所有帖子

这是我的搜索查询

SELECT * FROM wp_posts WHERE post_title like '%$search%' AND post_type = 'post' AND post_status = 'publish' ORDER BY post_date DESC

在此查询中，我不需要图书类别帖子。当我搜索任何关键字时，需要显示除图书类别帖子

之外的所有帖子

有什么帮助吗？

尝试以下:-

14是类别ID

 $request = $wpdb->prepare("SELECT * FROM $wpdb->posts 
  LEFT JOIN $wpdb->term_relationships ON($wpdb->posts.ID = $wpdb->term_relationships.object_id)  
  LEFT JOIN $wpdb->term_taxonomy ON($wpdb->term_relationships.term_taxonomy_id = $wpdb->term_taxonomy.term_taxonomy_id)  

  WHERE ($wpdb->term_taxonomy.term_id <> 14  
     AND $wpdb->term_taxonomy.taxonomy = 'category'   
     AND $wpdb->posts.post_type = 'post'  
     AND $wpdb->posts.post_status = 'publish'
     AND post_title like '%$search%'
     AND post_date >= '" . date('Y-m-d').")");
