Javascript 使用准备好的语句和PDO更新两个表
我试图更新两个表中的数据，根据下面的代码，只有第一个表“学生信息”得到更新 漏掉“培训信息”表未更新。这两个表由IndexNo链接。我需要代码的指导，告诉我如何使用示例语句同时更新这两个表。 请注意，我尝试使用给定的URL获取id值。这有助于我在一次操作中查看和更新有关IndexNo的一个不同列的数据Javascript 使用准备好的语句和PDO更新两个表,javascript,php,jquery,mysql,pdo,Javascript,Php,Jquery,Mysql,Pdo,我试图更新两个表中的数据，根据下面的代码，只有第一个表“学生信息”得到更新 漏掉“培训信息”表未更新。这两个表由IndexNo链接。我需要代码的指导，告诉我如何使用示例语句同时更新这两个表。 请注意，我尝试使用给定的URL获取id值。这有助于我在一次操作中查看和更新有关IndexNo的一个不同列的数据 URL: http://localhost/sample/updateStudentInfo.php?id=14 updateStudentInfo.php代码如下 &

请添加此错误报告（E\u ALL）；ini设置（“显示错误”，1）显示是否有任何错误。@Akram Fares没有错误，我正在使用firebug。我认为问题在于“IndexNo='$id'”上的第二个更新查询没有被识别。谢谢
