我有一个问题，我想编辑客户信息，但我只想一次更新一位客户的记录。我尝试添加 _SESSION['customerCode'] 但似乎不起作用。
<?php
$connection =
mysql_connect("com-db-02.student-cit.local", "team16", "DbSLzU")
or die (mysql_error());
$db = mysql_select_db("team16") or die(mysql_error());
$FName = $_POST['fname'];
$LName = $_POST['lname'];
$Email = $_POST['custemail'];
$Address = $_POST['address'];
$Town = $_POST['town'];
$County = $_POST['county'];
$Eircode = $_POST['eircode'];
$Phone = $_POST['phone'];
$query = mysql_query("UPDATE CUSTOMER set custFName = '$FName', custLName = '$LName', custemail = '$Email' where customerCode = "$_SESSION['customerCode']"") or die(mysql_error());
?>
我收到意外错误“$_SESSION”(T_VARIABLE)
还可以添加而不更新那些空白字段，因此如果客户只想更改其地址，其他字段不会被清除
最佳答案
您的连接有误。让它像这样 .$_SESSION['customerCode']
尝试下面的代码。
session_start();
$custCode = $_SESSION['customerCode'];
$query = mysql_query("UPDATE CUSTOMER set custFName = '$FName', custLName = '$LName', custemail = '$Email' where customerCode = ".$custCode) or die(mysql_error())
Also is it possible to add not update those fields that are blank, so if customer wants to change their address only, other fields won't get wiped out
