Ok, almost there, just need a little help with Set::
I'm using
Set::extract('/Follower/UsersUser', $user)
to get all the data from the association table of a given user, wich when
debugged produces an array like this one :
array(
(int) 0 => array(
'UsersUser' => array(
'id' => '36',
'follower_id' => '1',
'following_id' => '2'
)
),
(int) 1 => array(
'UsersUser' => array(
'id' => '37',
'follower_id' => '3',
'following_id' => '2'
)
)
)
Now, the only thing left is to find which Set:: to use :
Indeed, I just have to check if any array contains a 'follower_id' wich is
equal to $this->Session->read('Auth.User.id <http://auth.user.id/>'), and
if so, return the associated 'id' value. (wich will be passed to the delete
button).
Any clue on doing this ? I'm reading the Cookbook page for Set:: but I
really can't figure out.
Many thanks.
