编辑表单显示没有数据，并且在发布到数据库时无法保存
我的编辑表单没有错误，但我想编辑的数据没有显示。
我尝试在编辑表单中插入新信息，认为信息可能会改变，但什么都没发生。
以下是我的代码。

我的数据库表datastaf如下所示：
我在这些链接上找不到答案：
3 个答案:
答案 0 :(得分：1)
乍一看，您正在使用方法发布并尝试使用GET检索数据，请改用$ _POST
e.g。
$id = isset($_POST['id']) ? $_POST['id'] : '';
答案 1 :(得分：0)
首先确保您获取数据。
例如： $ _GET ['nama']应该具有您正在寻找的价值 $ nama = isset（$ _ GET ['nama']）？ $ _GET ['nama']：'';
你可以使用die（$ _ GET ['nama']）;并检查你是否得到了这个价值。
答案 2 :(得分：0)
假设您已建立连接，我做了一些更改 随意调整它。
<?php
include('db.php');
if(isset($_GET['id']))
{
$id=$_GET['id'];
if(isset($_POST['update']))
{
$nama=$_POST[''];
$noIc=$_POST['noIc'];
$gred=$_POST['gred'];
$unit=$_POST['unit'];
$catatan= $_POST ['catatan'];
$status= $_POST ['status']
$updated=mysql_query("UPDATE datastaf SET unama='$nama', noIc='$noIc', gred='$gred', unit= '$unit', catatan='$catatan', status='$status' WHERE id='$id'")
or die();
if($updated)
