Craig,
First off, where is the $db variable being set? You include it in:
$result = mysql_query($query, $db);
which is line 65, but, according to your function, it's not passed into the
function as an argument and I don't see you setting $db equal to anything
inside the function.
Second, why are you checking
if(!$query)?
You set $query to the string
$query ="SELECT username FROM users WHERE username=('$username')";
so why would it never NOT be set? Maybe you mean to check to see if the
query produced any results? In which case you should probably be checking
if(!$results).
Additionally, you should probably add an or die(mysql_error()) after your
mysql_query... line to display errors from the database.
And if your query process fails at line 65 because $db isn't defined, then
line 70 won't work because you haven't performed a query to return any rows.
Hope this helps.
Rich
