$user = $_SESSION['username'];

$result = mysql_query($sql) or die(mysql_error()); <---- Why is this here? $sql isn't defined until several lines later, so of course the query is empty.

if ($_POST['submit'])
{
$_POST['message'] = mysql_real_escape_string(htmlentities($_POST['message']));

$sql = "INSERT INTO chat (user, message) VALUES ('$user', '$_POST[message]')";
$result = mysql_query($sql) or die();

 

See my comment in the code.
