[quote author="yongkhun" date="1183016028"]Is there a way to call the functions of another controller from a different controller? I try to do like $this->another_controller->function1() but error said "calling function on non-object". How? Thanks![/quote]
No. And that is not the way to go with MVC. You should use a Model to place the reusable functions and the call them in the Controllers that will output the data using a View.
You may use the helpers approach as well, but only if it is just one small function, like an string replace or something like that.
