我已经在$_SESSION[' ']的phpmyadmin customer表中找到了值（在其中包含id，cust_name，cust_firstname，{{1 }}，cust_lastname，cust_add和cust_tel），我将此用于登录目的。
然后在我的cust_email中声明类似
SessionHandler.php所以，每当有人登录我只会使用//check whether the query was successful or not
if(isset($result))
{
if(mysql_num_rows($result) == 1)
{
//Login successful
session_regenerate_id();
$member = mysql_fetch_assoc($result);
$_SESSION['SESS_CUST_ID'] = $member['id'];
$_SESSION['SESS_CUST_EMAIL'] = $member['cust_email'];
$_SESSION['SESS_CUST_NAME'] = $member['cust_name'];
$_SESSION['SESS_CUST_FIRST'] = $member['cust_firstname'];
$_SESSION['SESS_CUST_ADD'] = $member['cust_add'];
$_SESSION['SESS_CUST_TEL'] = $member['cust_tel'];
$_SESSION['STATUS'] = true;
session_write_close();
header("location: http://localhost/wedding/user/dresses.php");
exit();
}
else
{
//login failed
header("location: cust-login-failed.html");
exit();
}
}
else
{
die("Query failed");
}
问题是，我正在做一个购物车，我希望登录的客户名称或我希望<?php echo $_SESSION['SESS_CUST_FIRST'] ?>的其他单词以新表名$_SESSION['SESS_CUST_FIRST']插入到数据库中order，id，product_name，product_code，price，product_size和product_qty。
这是衣服页面中的按钮添加到购物车的表单：
cust_firstname但每当我开始添加到购物车时，它将首先提交给<form method="POST" action="dress-isikan.php">
<table>
<tr>
<td colspan="1" rowspan="5"><img src="/wedding/dress/Large/01.jpg"></td>
<td style="vertical-align: top;"><big style="font-family: DFKai-SB;">Tulip Wedding Dress (WD01)<input type="hidden" name="product_name" value="Tulip Dress">
</td>
</tr>
<tr>
<td><input type="hidden" name="product_code" value="WD01"></td>
</tr>
<tr>
<td style="vertical-align: top;">Beautiful tulip wedding dress with flower lace on the chest</td>
</tr>
<tr align="center">
<td style="vertical-align: top;">Price: RM 799
<input type="hidden" name="price" value="799.00"><br>

<select name="product_size">

<option>38</option>
<option>40</option>
<option>42</option>
<option>44</option>
<option>46</option>
<option>48</option>
</select>
</big> </td>
</tr>
<tr>
<td style="vertical-align: top; text-align: center;"><br><big><big>
<input type="hidden" value="<?php echo $_SESSION['SESS_CUST_FIRST']; ?>" name="$cust_name;">
Quantity:</big></big> <input type="number" name="product_qty" min="1" max="11" value="1"><br>
<br>
<input type="submit" class="btn btn-default" value="Add to cart" ><br>
</td>
</tr>
</table>
</form>
：
dress-isikan.php它会说<!-- dress-isikan.php -->
<!-- To insert data of masuk.php into database. -->
<?php
include("dress-dbase.php");
extract( $_POST );
$query = "INSERT INTO order VALUES ('', '$cust_name', '$product_name','$product_code','$price','$product_qty','$product_size')";
$result = mysql_query($query, $conn) or die("Could not execute query in dress-isikan.php");
if($result) {
echo "<script type='text/javascript'> window.location='checkout.php' </script>";
}
?>
无法执行查询，我不知道查询有什么问题。我想我没有做错任何事。有时，我尝试将其提交到数据库表dress-isikan.php中的$_SESSION[' ']事件总是有问题。我只是按照我的讲义。有谁知道吗？
