I might b wrong but I think you have this backwards. The
Following/Follower arrays will contain all of the other users which
the *current* user is following or being followed by, respectively. So
by definition, Auth.User.id will be found in every entry in both
arrays (ID #2 in the example above).
So, let's say you have an array of all users and are listing their
names. If the current user is following one of them you want to
include an "unfollow" link which will delete the relationship. What
you need to do is look for the ID of the other user in the Following
array.
For example, if your users are in a $data array which look slike this:
array(
'User' => array(
'id' => some_id
...
),
...
);
$followers = $this->Session->read('User.follower');
$followings = $this->Session->read('User.following');
foreach($data as $d)
{
// print the name and whatever other info ...
$follower = Set::extract('/UsersUser[follower_id='.$d['User']['id'],
$followers);
if (!empty($follower))
{
// create delete link, passing $follower['id'] to delete action
}
else
{
// create link to follow, passing $follower['id'] to add action
}
}
