Something wrong with my code , guys?

<?php
require('connection.php');
if(isset($_GET["food_update"])){
$food_update = $_GET["food_update"];
$calories_update = $_GET["calories_update"];
$id = $_GET["id_update"];
$query = "UPDATE food SET food='$food_update' , calories='$calories_update' WHERE id='$id_update'";
mysql_query($query) or die('cannot query');
}
?>
<form action="index.php" method="get">
ID=<input type="text" name="id_update"> <br>
FOOD:<input type="text" name="food_update"> <br>
CALORIES:<input type="text" name="calories_update">
<input type="submit" value="submit">

Hey asaf omri,

I noticed that you are setting the id to "$id" instead of "$id_update" as you have in that SQL query string. You will want to update one of those sections to whichever variable name you need it to be because right now, "$id_update" can't be put into the database because it's undefined but "$id" is defined.
