提交后我的数据库没有更新

-2

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，用户决定要将哪个员工分配给时间段，删除时间，点击提交，然后数据库会随新值一起更新，然后再次显示表单，除db之外的所有工作都正常没有得到更新。这里是我想你需要看我的代码的一部分：提交后我的数据库没有更新

<?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);  
?>

当我试图在phpMyAdmin这个查询来更新它的工作的价值！但不在我的代码中

您正在使用周围的表和列名的单引号（而不是反引号，但你并不需要引号的话）。我认为这是一个印刷错误，并投票结束这些问题。 – 2014-11-22 15:26:48

UPDATE 'Specialist' SET 'Time_in' 
    ^  ^

表名不能放在引号内。这是您的查询失败的主要原因。您也没有检查查询执行的结果。

你提到的问号在哪里？请你解释一下 – user3419062 2014-11-22 15:28:46

引号，而不是问号。我刚刚更新了答案，提到哪些。 – 2014-11-22 15:30:30

我必须使用pdo吗？我真的不明白pdo是什么 – user3419062 2014-11-22 15:31:18
