Fatal error: Call to undefined method

boltsabre, errr.... no, in the userguide is just an example that you could do it that way, but it doesn't mean you have to. Perkin5's ways is already good.

Perkin5, you saw only that error ? there should be something more about which method is undefined. Are you sure it's the print_r() line? or was it get_code() that was undefined? In that case, show us the code above the get_code(). Sometime an extra "}" would make a lot of confusing errors.
