Question

当我发布表格时，我继续收到此错误。

致命错误：未捕获异常'PDOException'，消息'SQLSTATE [42S22]：找不到列：1054 /home /u717042829 / public_html/paststudent.php:273中的'字段列表'中的未知列'attendanc'堆栈跟踪：＃0 /home/u717042829/public_html/paststudent.php(273）：在第273行/home/u717042829/public_html/paststudent.php中抛出PDOStatement-＆gt;执行（数组）＃1 {main}

我不确定我的代码有什么问题。

<?php 
error_reporting(E_ALL); ini_set('display_errors', 1);
require("includes/config.php");
//if not logged in redirect to login page
if(!$user->is_logged_in()){ header('Location: login.php'); }

Answer 1

很清楚什么是错误的。

MySQL正在返回错误。 MySQL告诉您， attendanc 列不是paststudent中的有效列。

查看INSERT语句中的列列表，并将其与表中列的名称进行比较。（我怀疑你从专栏名称中删除了e ... attendance ，但这只是一个猜测，因为我们没有看到表格定义。）

未捕获的异常'PDOException'，我的表单不会发布到我的phpmyadmin数据库
