[SOLVED] Updating Table Error

[oubipaws]

First off, the error message:
[code]You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE id='7'' at line 1[/code]

Now for the who, what, when, and where;  I have a website and I am designing a small content management system, but I haven't really messed with PHP in roughly 2 years so I'm a little bit rusty.  I have many (roughly 15-20 tables) tables and I'm trying to write a simple update script.  I thought it would be uberly easy, but apparently it is not.

Here is my code for the first table's page, called templates.php:
[code]<?php
$username="removed";
$password="removed";
$database="templates";

mysql_connect(localhost,$username,$password);
@mysql_select_db($database) or die( "Unable to select database");

if (isset($_GET['id'])){
$query = "SELECT * FROM templates WHERE id ='" .$_GET['id']. "'";
$result = mysql_query($query) OR die('Error: ' . mysql_error());
} else {
echo "No item selected";
}

echo "<br><br>";
while($r=mysql_fetch_array($result)){

$id = $r["id"];

$preview = $r["preview"];

$name = $r["name"];

$code = $r["code"];

}

?>
<form action="update-templates.php" method="post">
ID #:<input type="text" name="ud_id" value="<? echo $id; ?>">
Preview: <input type="text" name="ud_preview" value="<? echo $preview; ?>"><br>
Name: <input type="text" name="ud_name" value="<? echo $name; ?>"><br>
Code: <textarea name="ud_code" rows=10 cols=40><? echo $code; ?></textarea><br>
<input type="Submit" value="Update">
</form>[/code]

Then the update-templates.php php code:
[code]<?
$username="removed";
$password="removed";
$database="templates";

mysql_connect(localhost,$username,$password);
@mysql_select_db($database) or die( "Unable to select database");

$ud_id=$_POST['ud_id'];
$ud_preview=$_POST['ud_preview'];
$ud_name=$_POST['ud_name'];
$ud_code=$_POST['ud_code'];


$query = "UPDATE templates SET preview='$ud_preview', name='$ud_name', code='$ud_code', WHERE id='$ud_id'";
$result = mysql_query($query) or die(mysql_error());
?>[/code]

Any thoughts?  Any suggestions?  I highly appreciate any help or advice guys!

Change this:
$query = "UPDATE templates SET preview='$ud_preview', name='$ud_name', code='$ud_code', WHERE id='$ud_id'";

to this:
$query = "UPDATE templates SET preview='$ud_preview', name='$ud_name', code='$ud_code' WHERE id = '$ud_id'";

You have an extra comma before the "WHERE".

Thank you so much!  I knew it had to be something simple that I was missing.  I highly appreciate it!
