php语法利用mysql语法获取指定分类下的文章

wordpress做接口，php文件中利用mysql语法获取指定分类下的文章，下面编程教程网小编给大家简单介绍一下具体实现代码！

具体实现代码如下：

 $title=$_GET['title'];
 $id='10'; //栏目id=10
 $pageSize = 20;
 $pageNumber=($_GET['pageNumber'] - 1) * $pageSize;
 //读取所有数据表中的字段 表名
 $sql='SELECT ID,post_title,post_date,post_content FROM wp_posts,wp_term_relationships,wp_term_taxonomy
 WHERE ID=object_id and wp_term_relationships.term_taxonomy_id = wp_term_taxonomy.term_taxonomy_id
 and post_type="post" and post_status = "publish" and wp_term_taxonomy.term_id = "'.$id.'"
 and taxonomy = "category" AND post_title LIKE "%'.$title.'%" LIMIT 100';
 
 //使用query()方法去链接数据库并执行语句
 $result = $demo -> query($sql);
