Syntax error due to using a reserved word as a table or column name in MySQL

I'm trying to update my database entries with this form:
<form method="post" action="inc/update.php">
<?php foreach ($links as $row) {
?>
<div class="btn_admin">
<p>
<label>Titulo</label>
<input type="text" name="title[]" value="<?php echo $row["desc"] ?>">
</p>
<p>
<label>Url</label>
<input type="text" name="url[]" value="<?php echo $row["url"] ?>">
<input type="hidden" name="id[]" value="<?php echo $row["id"] ?>" />
</p>
</div>
<?php }
?>
<input type="submit" name="submit" value="Update Links" />
</form>
On my update.php file:
if ($_SERVER["REQUEST_METHOD"] == "POST"
&& $_POST["submit"] == "Update Links") {
include_once 'db.php';
$db = new PDO(DB_INFO, DB_USER, DB_PASS);
foreach($_POST['id'] as $id ) {
$title=$_POST["title"][$id-1];
$url=$_POST["url"][$id-1];
$sql = "UPATE index_links
SET desc=?, url=?
WHERE id=?";
$stmt = $db->prepare($sql);
$stmt->execute(array($title, $url, $id-1));
$stmt->closeCursor();
}
}
I've looped through $title and $url and everything is being 'grabbed' correctly, but the query is failing somehow with no errors.
I have even tried messing with erroneous query syntax (like in the query in the example above - "UPATE"), no errors whatsoever... and yes, the foreach loop is being accessed.
This seems like such intro level stuff, but I'm looking at this for an hour or so no and mind=blown... there are other queries (not UPDATE ones) on my project which are working fine.

In your case, the query probably fails because desc is a reserved word in mySQL.
PDO can be very secretive about its error messages by default. See this question on how to change that.
