Zend框架发布日期问题

有一个支付系统（LiqPay），它通过支付发送一个帖子请求，我需要接受它们，但什么都没有出来，$data和$signature = null。在一个单独的php文件中，所有完全被接受的，没有。如果你调用帖子 init() 方法被接受，但不是我的字段 - 这个用户 ID（在会话中），它只在 indexAction 中。

   class User_FeedController extends Zend_Controller_Action {
        protected $bd_usinfo;
        protected $hidefree = false;
    public function indexAction() {
            $data = $_POST['data'];
            $sigrnature = $_POST['signature'];
            $getfeed        = $this->bd_usinfo->getinfobyuserid($this->session['user_id']);
            $this->view->ud = $getfeed;
            $this->view->me = $this->session;
            $this->view->hidefree = false;
            //$this->view->hidefree = true;
            if ((($this->bd_usinfo->isProfessional($this->session['user_id'])) || ( $this->session['role'] == '4'))) {
                $this->view->hidefree = true;
                $this->view->prof     = 1;
            }
            if ($getfeed->feedtime != null) {
                $this->view->hidefree = true;
            }
            if ($this->session['feed'] == 0)
                $this->view->hidefree = true;
            $chng = $this->_request->getParam('chs');
            if ($getfeed->feed != '-1' && $chng == false && $stop != 1) {
                $this->view->alreadyactive = "У вас активирована ";
                if ($getfeed->feedtime != null) {
                    $time_feed = date('n', $getfeed->feedtime - mktime(0, 0, 0, date('m') + 1));
                    // $this->view->alreadyactive .= $feeds[$time_feed];
                    $this->view->alreadyactive .=" платная подписка до " . date('d.m.Y', $getfeed->feedtime);
                }
                else {
                    $this->view->alreadyactive .= " бесплатная подписка";
                }
            }
            $this->view->role     = $this->session['role'];
            $this->bd_config      = new Admin_Model_Config();
            $settings             = $this->bd_config->getSettings();
            $settings             = $settings->toArray();
            $this->view->settings = $settings;
        }
