这是更新数据的第二个文件：-Update-item.php
<?php
$servername = "127.0.0.1";
$username = "root";
// Create connection
$conn = mysql_connect($servername, $username,"");
// Check connection
if (!$conn)
exit();
else
$id=$_GET['id'];
$name=$_GET['name'];
$dept=$_GET['dept'];
$make=$_GET['make'];
$vat=$_GET['vat'];
$mrp=$_GET['mrp'];
$pack=$_GET['pack'];
$unit=$_GET['unit'];
$ex=$_GET['ex'];
$stock=$_GET['stock'];
$desc=$_GET['desc'];
echo "id=",$id;
echo "dept=",$dept;
echo "make=",$make;
echo "name=",$name;
echo "vat=",$vat;
echo "mrp=",$mrp;
echo "pack=",$pack;
?>
输出是：-
id=dept=make=name=vat=4mrp=100pack=1*100
我无法获取变量 ID、名称、部门、品牌的值。
它是网址
http://127.0.0.1:8888/Pharmaceutical%20Distribution%20System/PDS/update-item.php?vat=4&mrp=100&pack=1*100&unit=ml&ex=2015-12-31&stock=0&desc=++++++++++++++++++++++++++++%09
【问题讨论】：
这是很多代码。id 字段是否会因禁用而改变？ ***.com/questions/8925716/… 我在您的脚本中观察到的其他问题，您正在混合使用 mysql 和 mysqli 驱动程序。您的代码对 SQL 注入开放。
【参考方案1】：
编辑 2： 删除了不相关的信息。
编辑： disabled inputs are not posted
【讨论】：
我知道，但问题是为什么数据不在 URL 中！ 这是评论，不是答案。 @chris85，我的声望等级不允许添加 cmets。感谢您的反对。 你为什么不写一个与问题相关的答案，我会取消反对票。删除错误的You are trying to $_GET['id'] in Update-item.php, but your pasted URL doesn't contain such query parameter.，因为这与问题无关。以上是关于某些表单输入未通过 GET / POST 发送 [重复]的主要内容，如果未能解决你的问题，请参考以下文章
