我有一个PHP脚本,我正在努力工作,我基本上只是从教程中提取并根据我的需要进行了修改。这是我第一次尝试使用php,所以请放轻松。
我有3个文件
List_records从mysql中的表中读取数据。 list_records中的表有一个编辑功能,可以将你带到update.php,它在db表中显示数据。
Update.php有一个提交按钮,用于使用update_ac.php更新mysql,使用$ _GET ['id]使用url中的id字段更改了所有信息。
我知道这个脚本对slq注射非常开放,但我打算只在本地环境中使用它,它不会暴露在互联网上,只有我自己和另外一个人会使用这个页面所以它不是真的一个问题。
无论如何,我已经确认了几件事: -
有人能指出我正确的方向吗?
以下是更改了数据库连接详细信息的3个文件

答案 0 :(得分:8)
您的更新查询应为
// update data in mysql database
$sql="UPDATE ports SET Customer='".$_POST['Customer']."', Number='".$_POST['Number']."' WHERE id='".$_POST['id']."'";
$result=mysql_query($sql)or
die ("this stuffedup");
答案 1 :(得分:1)
1.You have to pass a id when clicking a submit in update.php by
<a href="update_ac.php?id=<?php echo $rows['id']; ?>"><input type="submit" name="submit" value="Submit"></a>.
2.The line $id=$_GET['id'] is used in update_ac.php before insert query.
答案 2 :(得分:0)
$sql="UPDATE ports SET Customer='Customer', Number='Number' WHERE id='id'" ;
这一行是错误的,你用STRING而不是整数来更新它。你应该把
$sql="UPDATE ports SET Customer='Customer', Number='Number' WHERE id='".intval($_REQUEST['id'])."'"
