MySQL: "You have an error in your SQL syntax... near 'desc) VALUES ('Idea','Description')'"

Question

I am trying to get MySQL to work for my form submissions. I am having a problem when I try to insert into a table.
When I put information into my form and click submit (in this example the information is "Idea" in one field and "Description" in the other) I get this response:

"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 'desc) VALUES ('Idea','Description')' at line 1"

I am running a .php file from a webserver to execute this script.

Here is my current code:

<?php

mysql_connect("localhost","root","") or die(mysql_error());
mysql_select_db("date_ideas") or die(mysql_error());
$title=$_POST['title'];
$title=mysql_real_escape_string($title);
$desc=$_POST['desc'];
$desc=mysql_real_escape_string($desc);
$submit="INSERT INTO ideas (title, desc) VALUES ('$title','$desc');";

mysql_query($submit) or die(mysql_error());

echo ("Idea submitted.  Click <a href='Webroot/submit.php'>here</a> to go back and post another idea.");
?>

If you call an echo of the variables used it succeeds at passing through the information, so that's not the problem.

Answer 1

desc is a reserved keyword (short for DESCENDING in ORDER BY).

Enlose it into backticks:

INSERT INTO ideas (title, `desc`) VALUES ('$title','$desc');
