Because your CI code doesn't work for some reason...

I'm wondering why you're doing this:

Code:

$this -> db -> where('username = ' . "'" . $username . "'");

When you could just...

Code:

$this -> db -> where('username', $username);

If it were me, I'd try just hitting that controller method as a direct browser request and testing the results there. Turn on the profiler to display all of the queries being run and turn error reporting up.

In your controller...

Code:

$this->output->enable_profiler(TRUE);
