redirecting to unknown link after clicking on button

[Suyog Choure]

When i am clicking on Edit User button user information is getting updated but at the same time page is redirecting to link which is not present.

<? php
if(isset($_POST['edituser'])){

	$euser = " UPDATE users SET uname='".$_POST['rudname']."', upass='".$_POST['rudpass']."', uemail='".$_POST['rudemail']."'";

	if(isset($_POST['membership'])){

		$time = $_POST['timem'];

		$euser.= " ,acc_type=1  , p_start=NOW(), p_end = (NOW() + INTERVAL {$time} MONTH)";

	}

	$euser.= " WHERE uid=".$_GET['uid'];

	$eres = mysql_query($euser,$con);if($eres){

		$_SESSION['crudusererr'] = "User ".$_POST['rudname']." Updated !";

		header("Location: /".$_GET['uid']);

	}else {die("Editing user <b>".$_POST['rudname']."</b> fail ! <br \>".mysql_error());}

?>

                
                <div style="float: left;" >

			<input style="width:180px; height:40px;font-size: 15px;color: #00cc66;" type="submit" name="edituser" value="Edit User <?php echo $ouname; ?>" />

		</div><!-- edit -->

You need to provide a <form> element to identify where to send the data upon clicking the button. Example:

<form action="xxx.php" method="post">
  <input ... type="submit" name="edituser"  .../>
</form>
