PHP的功能已经实现,却总是报错
代码的目的是实现图片上传到指定目录,并且在mysql中记录图片路径。
现在目的已经实现,可是页面总是报错,

报错内容就是第二行:

<?php if ($_GET['action'] == "save"){  //这行报错:Notice: Undefined index: action in D:\xampp\htdocs\upload.php on line 2
include_once('MYDBconn.php');
include_once('UPclass.php');
$titles=$_POST['title'];
$images=$uploadfile;
if($titles == "")
echo"<Script>window.alert('No title');history.back()";
$sql="insert into product(title,pic) values('$titles','$images')";
$result=mysql_query($sql,$conn);
echo"<script>window.alert('congratunations');location.href='upload.php'</script>";
}
?>



<title>images transfer</title>


    
Copy after login
 
titles:
Images:
 


麻烦指教一番,究竟是哪里出错了,谢谢

------解决方案--------------------
if ( isset($_GET['action']) && $_GET['action'] == "save" )

------解决方案--------------------
上个问题帖子答过你了,在置顶的基础问题帖子里也有提到这个问题
这是一个提示不是错误

在传递过来的参数 包括post 在新版本,应该是5.3X的某个版本后需要做一个

isset进行判断,否则就会出现这个提示,当然你可以调整出错提示的等级来屏蔽这样的提示.
