$res = $sth->execute($prep);

something i am not doing right

Answer 1

Consider moving the query string into a separate variable:

$sql = "INSERT......";
$sth = $db->prepare($sql);

and then try and see the $sql content (using var_dump($sql) for instance). This may set you on the right path.

Also, add this after $sth->execute() :

$error = $db->errorInfo();
echo $error[2];

This will show you the MySQL error message, if there is one. (Don't forget to remove all this debug output later though.)
