【问题描述】：
打开此页面时，必须显示多个表单。每个表单都是针对特定员工的，用户决定要分配给哪个员工的时间段，选择时间，单击提交，然后使用新值更新数据库并再次显示表单，除了数据库之外一切正常没有得到更新。 这是我认为您需要查看的代码部分：
<?php
ini_set('display_errors',1);
error_reporting(E_ALL);
// Start database connection
include ('connection.php');
session_start();
// Write QUERY
if ( isSet($_POST['Time_in'], $_POST['Time_out'], $_POST['Spec_ID'] ) ) {
$qry="UPDATE 'Specialist' SET 'Time_in' = '".$_POST['Time_in']."' , Time_out = '".$_POST['Time_out']."' WHERE Spec_ID ='".$_POST['Spec_ID']."';";
$result = mysql_query ($qry);
$qry = 'SELECT * FROM Specialist' ;
}
else
$qry = 'SELECT * FROM Specialist' ;
//Run QUERY
$result = mysql_query ($qry);
?>

当我在 phpmyadmin 中尝试此查询以更新它的值时！但不在我的代码中
【问题讨论】：
-
您在表名和列名周围使用单引号（而不是反引号，但您根本不需要引号）。我认为这是一个印刷错误并投票结束此类问题。
