mysql insert error

[speedy_rudolf]

Hi. I think you all know me by now so I'll cut to the chase.

<?php
$host="edited";
$username="edited";
$password="edited";
$db_name="edited";
$tbl_name="topic";
// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB");

$name=$_POST['name'];
$detail=$_POST['details'];

$sql="INSERT INTO $tbl_name(topic, detail, datetime)VALUES('$name', '$detail', NOW())";
$result=mysql_query($sql);

if($result){
header("location:site.html");}
else{
echo("I have failed you master.");}
?>

 

Displayed error: "I have failed you master." Anyone know a possible cause? Thanks. Bye.

If you echo mysql_error(); it will tell you why the query failed.
