CakePHP – 保存一个会话变量会删除另一个

我在Cake PHP中使用会话变量来存储我的相关用户Twitter和Facebook数据,当用户登录时,如果他已经链接了他的Twitter和FB帐户,则该信息被保存在我自己的用户数据旁边的会话变量中.

我有一个用户可以链接和取消链接所述社交网络数据的屏幕,问题如下：

假设我已连接两个网络,我决定断开与Facebook的连接,删除Facebook的会话变量.现在我希望重新连接到Facebook,我点击Connect按钮,Facebook数据被保存但由于某种原因它删除了Twitter变量.

我的流程的工作方式如下：

1)用户点击连接按钮.
2)用户被引导到社交网络身份验证.
3)用户被引导到一个获取所需数据的函数,将其保存在名为NetworkData的会话变量中,并被引导回他点击该按钮的页面.
4)提取NetworkData,在会话中设置为相应的社交网络(Facebook或Twitter)并从会话中删除.

代码如下：

这是用户登录Twitter或FB后的指示功能：

function retrieve_network($page) {
      $networkData = null;
      $this->autoRender = false;
      $this->layout = 'ajax';
      if(isset($_GET['oauth_token'])) {
        $token = $this->TwitterHelper->setOAuthToken($_GET['oauth_token']);
        $userinfo = $this->TwitterHelper->getTwitterUserInfo();
        $networkData = array(
          'TwitterData' => array(
            'username' => $userinfo['username'],'name' => $userinfo['name'],'token' => $token->oauth_token,'token_secret' => $token->oauth_token_secret
          )
        );
      } else if (isset($_GET['code'])) {
        $token = $this->FacebookHelper->facebook->getAccessToken();
        $userinfo = $this->FacebookHelper->getUserInfo();
        $networkData = array(
          'FacebookData' => array(
            'username' => $userinfo['username'],'email' => $userinfo['email'],'token' => $token,'link' => $userinfo['link'],)
        );
      }

      $this->Session->write('NetworkData',$networkData);

      if($page == 'settings') {
        $this->redirect(array('controller' => 'fonykers','action' => 'settings/networks'));
      }
    }

这是检索网络数据中的内容并将其设置为会话的函数：

function settings($tab) {
      $this->layout = 'frontend';  
      $this->Fonyker->recursive = -1;
      $this->TwitterData->recursive = -1;
      $this->FacebookData->recursive = -1;

      if(!$this->checkSessionCookie()) {
        $this->redirect(array('controller' => 'pages','action' => 'home'));
      }

      $fields = array(
        'Fonyker.id','Fonyker.username','Fonyker.name','Fonyker.email','Fonyker.gender','Fonyker.birthdate','Fonyker.image_url'
      );

      $fonyker = $this->Fonyker->find('first',array(
        'conditions' => array(
          'Fonyker.fonykid' => $this->Session->read('Fonyker.Fonyker.fonykid')
        ),'fields' => $fields
      ));


      $this->Fonyker->set($fonyker);

      $this->data = $fonyker;

      if($this->Session->read('NetworkData')) {
        $networkData = $this->Session->read('NetworkData');
        $this->Session->delete('NetworkData');  

        if($networkData['TwitterData']) {
          $networkData['TwitterData']['fonyker_id'] = $fonyker['Fonyker']['id']; 
          if($this->TwitterData->save($networkData)) {
            $this->Session->write('TwitterData',$networkData['TwitterData']);
          }
        } else if($networkData['FacebookData']) {
          $networkData['FacebookData']['fonyker_id'] = $fonyker['Fonyker']['id']; 
          if($this->FacebookData->save($networkData)) {
            $this->Session->write('FacebookData',$networkData['FacebookData']);
          }
        }
      }

      pr($this->Session->read());

      if(!$this->Session->read('TwitterData')) {
        $this->TwitterHelper->setTwitterObj();
        $this->set('twitterUrl',$this->TwitterHelper->twitterObj->getAuthorizeUrl(null,array('oauth_callback' => 'http://127.0.0.1/fonykweb/pages/retrieve_network/settings')));
      } else {
        $this->set('twitterUrl','#');
      }


      if(!$this->Session->read('FacebookData')) {
        $this->set('facebookUrl',$this->FacebookHelper->facebook->getLoginUrl(array('redirect_uri' => 'http://localhost/fonykweb/pages/retrieve_network/settings','scope' => 'email,user_birthday,publish_stream,offline_access')));
      } else {
        $this->set('facebookUrl','#');
      } 

      $this->set('tab',$tab);
    }

如果用户希望,这是删除网络的功能：

function remove_network($network) {
      $this->autoRender = false;
      $this->Fonyker->recursive = -1;
      $this->TwitterData->recursive = -1;
      $this->FacebookData->recursive = -1;
      $response = null;

      if($network == 'twitter') {
        $twitterData = $this->TwitterData->find('first',array(
          'conditions' => array(
            'TwitterData.fonyker_id' => $this->Session->read('TwitterData.fonyker_id')
          )
        ));

        if($this->TwitterData->delete($twitterData['TwitterData']['id'],false)) {
          $this->TwitterHelper->setTwitterObj();
          $twitterUrl = $this->TwitterHelper->twitterObj->getAuthorizeUrl(null,array('oauth_callback' => 'http://127.0.0.1/fonykweb/pages/retrieve_network/settings'));
          $this->Session->delete('TwitterData');
          $response = json_encode(array('ok' => true,'url' => $twitterUrl));
        } else {
          $response = json_encode(array('ok' => false)); 
        }
      }

      if($network == 'facebook') {
        $facebookData = $this->FacebookData->find('first',array(
          'conditions' => array(
            'FacebookData.fonyker_id' => $this->Session->read('FacebookData.fonyker_id')
          )
        ));

        if($this->FacebookData->delete($facebookData['FacebookData']['id'],false)) {
          $facebookUrl = $this->FacebookHelper->facebook->getLoginUrl(array('redirect_uri' => 'http://localhost/fonykweb/pages/retrieve_network/settings',offline_access'));
          $this->Session->delete('FacebookData');
          $response = json_encode(array('ok' => true,'url' => $facebookUrl));
        } else {
          $response = json_encode(array('ok' => false)); 
        }

      }

  echo $response; 
}

对不起,很长的帖子.
