Question

我正在创建一个仅限基本会员的网站，我的一个页面用于从管理员视图中编辑用户的信息。它访问名为contacts的数据库，然后访问表tblUsers，但是当它最终编辑它不保存的信息时，它就在某个地方。

<?php 
include("main.php");

connectDB();

//check for submit being pressed
if(isset($_POST['submit']))
{   //check for empty fields
    if($_POST['fName']!="" && $_POST['lName']!="" && $_POST['uName']!="" && $_POST['email']!="" && $_POST['address']!="" && $_POST['city']!="" && $_POST['state']!="" && $_POST['zip']!="" && $_POST['phone']!="" && $_POST['signup']!="")
    {
        $SQL="Update tblUsers SET firstName='".$_POST['fName']."', lastName='".$_POST['lName']."',userName='".$_POST['uName']."', email='".$_POST['email']."', address='".$_POST['address']."', city='".$_POST['city']."', state='".$_POST['state']."', zip='".$_POST['zip']."', phone='".$_POST['phone']."', signupDate='".$_POST['signup']."' WHERE userID=".$_POST['userID'];

        $response=mysql_query($SQL);
        //redirect with status update
        header("Location:editMember.php?id=".$_POST['userID']."&status=1");
    }
    else
    {   //redirect with status update
        header("Location:editMember.php?id=".$_POST['userID']."&status=2");
    }

}

//check for ID, if none redirect
if($_GET['id']=="")
{
    header("Location:adminView.php");
    exit;
}


//function to display form
function displayForm($strMessage, $userid, $response="")
{
    echo    "<center><strong>" . $strMessage . "</strong></center><br><br>";

userID正在寻找一个已发布的值，但从未在表单中发布，因此没有任何反应，问题已解答。

为什么我的查询从不正确编辑MySQL表的成员？
