        $is_friend = in_array($this->user['id'], $this->Friend->myFriends($user['User']['id']));

      else

        $is_friend = false;

      

      if($user['User']['privacy'] == array_search('friend', Configure::read('Site.privacy')))

      {

        if($this->user['id'] != $user['User']['id'] && !$is_friend)

        {

          $this->flash('error', ucfirst('this profile is only viewable by owner\'s friends'));

          $this->redirect('/send_request/' . $user['User']['username']);

        }

      }

      elseif($user['User']['privacy'] == array_search('private', Configure::read('Site.privacy')))

      {

        if($this->user['id'] != $user['User']['id'])

        {

          $this->flash('error', ucfirst('this profile is only viewable by its owner'));

          $this->redirect('/owner/' . $user['User']['username']);

        }

      }

      

      $this->set_title(ucfirst(i18n::translate('info')) . ' : ' . $user['User']['firstname'] . ' ' . $user['User']['lastname']);

      

      $this->set('user_obj', $user);

<?php

class Friend extends AppModel {

  var $name = 'Friend';

    var $validate = array(

     'user_id' => array(

      'rule' => 'notEmpty',

      'message' => 'Please enter a valid user',

     ),

     'friend_id' => array(

      'rule' => 'notEmpty',

      'message' => 'Please enter a valid friend',

     ),

 );

 

  var $belongsTo = array('User' => array('foreignKey' => 'friend_id'));

  function myFriends($id = null)

  {

    $friends_ids = $this->generateList(array('Friend.user_id' => $id), array('Friend.friend_id' => 'ASC'), null, '{n}.Friend.friend_id', '{n}.Friend.friend_id');

    return is_array($friends_ids) ? $friends_ids : array();

  }

  function afterDelete()

  {

  }

}

?>
