html - Undefined index: image in C:\wamp\www\netupdate.php on line 21 -

i facing weird problem. here file upload snipped of form through trying upload image server

<input type="file" name="image" id="image"> 

and getting error:

undefined index: image in c:\wamp\www\netupdate.php on line 21 

my upload script following

// file upload scrpt    $name= $_files['image']['name'];   $tmp_name = $_files['image']['tmp_name'];    $type = $_files['image']['type'];    $size = $_files['image']['size'];   $pathandname = "file:///c:/wamp/www/upload/networking/".$name;   $moveresult = move_uploaded_file($tmp_name, $pathandname); 

now weird portion other parameters being accepted in php script other image, writing database , giving success message portion giving errors , weirder part similar script working in other mysql table guess there nothing wrong in php_ini.

you missing enctype="multipart/form-data" on <form> element.

<form action="netupdate.php" method="post" enctype="multipart/form-data">
