can some one help me please :)

What do you mean by connect the two ? One extends the other, so they are already connected.

[cleggy1987]

sorry using the login() function i cant access the database login using $this->query(); to return the value of true it will work passing data to and from mysql from a basic php script but getting to connect in another class file is driveing me mad

[diafol]

Sorry just scanned the code quickly. What about:

public function __construct(){
  parent::__construct()
}

in your child class? Don't know if that will work.

[cleggy1987]

Its ok i have fixed it now was a combo of lack of sleep and not thinking clearly made me cock up the hole script but a good night sleep helped and now works :) thanks any way lads :)
