OK, I figured out this should go into the controller.
But How can I use this function to alternate between two buttons follow /
unfollow *in the view *?
public function checkIfFollow() {
if (in_array(Set::extract('/Following/id', $this->Auth->user()),
$id)) {
// stop follow
} else {
//follow
}
}
Many thanks for your time.
