thanks to all!
...but i still have some doubts.
1.
if i write:
function view() {
$this->set('post', $this->Post->read());
}
then the urls post/view/1 and post/view/2 continue to show
respectively post n.1 and post n.2, i cannot understand how (maybe i
have to look depper in the code)
2.
ok but... if i have two identical pieces of code and i extract them in
someFunction() then post/someFunction becomes a valid url?
if so, how to avoid this behaviour?
3.
ok. so $this->data in the controller becomes $form->data in the
respective ctp file.
thanks again to all!
