PHP MSQL FORM查询将无法连接

Question

嗨，我一直试图做的，我从PHP订单页面提交表单中的代码，以便它可以更新所需的信息

我的MySQL数据库已经得到了订单PHP代码这里：

<?php 

if (isset($_POST['submit'])){ 

    $conn = mysql_connect('url','username','password'); 
    if (!$con){ 
     die("Could Not Connect: " . mysql_error()); 
    } 

    mysql_select_db("db",$conn); 

    $sql = "INSERT INTO Order_Information(Order_ID,Order_Items,Order_Quantity) VALUES (null,$_POST[items]','$_POST[qty]')"; 

    mysql_query($sql, $con); 

mysql_close($con); 
} 

?> 

显然，我的用户名和密码，我将不显示，但是当我点击提交按钮，它说，它无法连接。

你可以尝试自己的形式本网站： http://zim.cs.uow.edu.au/~ga420/order.php

怎么就被说清楚的时候，我一直把正确的细节我无法连接

谁能帮助？这一直强调我出去。“（

你的帮助是极大的赞赏！

Answer 1

更改到这一点，你做了$连接，然后$ CON然后，'$_POST[items]','$_POST[qty]'在查询的一些错误

if (isset($_POST['submit'])){ 

$conn = mysql_connect('url','username','password'); 
if (!$conn){ 
    die("Could Not Connect: " . mysql_error()); 
} 

mysql_select_db("db",$conn); 

$sql = "INSERT INTO Order_Information(Order_ID,Order_Items,Order_Quantity) VALUES  (null,'$_POST[items]','$_POST[qty]')"; 

mysql_query($sql, $conn); 

mysql_close($conn); 
} 

。

希望这有助于

Answer 2

你需要序列化所有的输入/数量，如果你将在各个领域具有相同的名称“数量”，我会更新我的答案后，如果你做T得到这个答案。

你对你的代码还小错误，注意到这一点：

VALUES (null,'$_POST[items]','$_POST[qty]')"; - 你$ _ POST前失踪' [项目]

$conn = mysql_connect('zim.cs.uow.edu.au','username','password'); - $ 2 conn将 “N”

所以，一修改后的版本将是：

<?php 

if (isset($_POST['submit'])){ 

$con = mysql_connect('url','username','password'); 
if (!$con){ 
    die("Could Not Connect: " . mysql_error()); 
} 

mysql_select_db("db",$con); 

$sql = "INSERT INTO Order_Information(Order_ID,Order_Items,Order_Quantity) VALUES (null,'$_POST[items]','$_POST[qty]')"; 

mysql_query($sql, $con); 

mysql_close($con); 
} 

?>
