Question

我正在尝试为我的项目制作更新功能。

我有一张客户数据表，删除，添加功能正常，但每当我使用更新功能它将数据库中行的数据清空为空我尝试了其他的东西，但效果不好。这可能是一个小错误，但我似乎无法找到问题，因为我一直致力于其他项目wholeday：＆lt;

更新详细信息php文件

<?php
// include Database connection file
include("db_connection.php");

// check request
if(isset($_POST))
{
    // get values
    $id = $_POST['id'];
    $Surname = $_POST['update_Surname'];
    $Name= $_POST['update_Name'];
    $Address = $_POST['update_Address'];
    $Telephone = $_POST['update_Telephone'];
    $PurchaseDate = $_POST['update_PurchaseDate'];
    $Model = $_POST['update_Model'];
    $SerialNumber = $_POST['update_SerialNumber'];
    $Notes = $_POST['update_Notes'];
    

    // Update User details
    $query = "UPDATE Clients SET Surname = '$Surname', Name = '$Name', Address = '$Address', Telephone = '$Telephone', PurchaseDate = '$PurchaseDate', Model = '$Model', SerialNumber = '$SerialNumber', Notes = '$Notes' WHERE id = '$id'";
    if (!$result = mysql_query($query)) {
        exit(mysql_error());
    }
}

更新功能

function UpdateUserDetails() {
    // get values
    var update_Surname = $("#update_Surname").val();
    var update_Name = $("#update_Name").val();
    var update_Address = $("#update_Address").val();
    var update_Telephone = $("#update_Telephone").val();
    var update_PurchaseDate = $("#update_PurchaseDate").val();
    var update_Model = $("#update_Model").val();
    var update_SerialNumber = $("#update_SerialNumber").val();
    var update_Notes = $("#update_Notes").val();

    // get hidden field value
    var id = $("#hidden_user_id").val();

    // Update the details by requesting to the server using ajax
    $.post("ajax/updateUserDetails.php", {
            id: id,
            Surname: update_Surname,
            Name: update_Name,
            Address: update_Address,
            Telephone: update_Telephone,
            PurchaseDate: update_PurchaseDate,
            Model: update_Model,
            SerialNumber: update_SerialNumber,
            Notes: update_Notes
        },
        function (data, status) {
            // hide modal popup
            $("#update_user_modal").modal("hide");
            // reload Users by using readRecords();
            readRecords();
        }
    );
}

模态表格

Answer 1

$id = $_POST['id'];
$Surname = $_POST['update_Surname'];
$Name= $_POST['update_Name'];
$Address = $_POST['update_Address'];
$Telephone = $_POST['update_Telephone'];
$PurchaseDate = $_POST['update_PurchaseDate'];
$Model = $_POST['update_Model'];
$SerialNumber = $_POST['update_SerialNumber'];
$Notes = $_POST['update_Notes'];

您使用更新_ 作为帖子变量。但是你提供给jQuery post函数的实际键是不同的。实际键在每个作业左侧的下一个对象中定义。

     {
        id: id,

        Surname: update_Surname,

        Name: update_Name,

        Address: update_Address,

        Telephone: update_Telephone,

        PurchaseDate: update_PurchaseDate,

        Model: update_Model,

        SerialNumber: update_SerialNumber,

        Notes: update_Notes

    }

请改用以下内容。

$id = $_POST['id'];
$Surname = $_POST['Surname'];
$Name= $_POST['Name'];
$Address = $_POST['Address'];
$Telephone = $_POST['Telephone'];
$PurchaseDate = $_POST['PurchaseDate'];
$Model = $_POST['Model'];
$SerialNumber = $_POST['SerialNumber'];
$Notes = $_POST['Notes'];
