<?php   class grupondb_emailcatcher_model_observer {      public function __construct() {      }       public function displayemailcatcherpage($observer) {          $fronta = new mage_core_controller_front_action;         $fronta->loadlayout()->getlayout();          $ecookie = mage::getmodel('core/cookie')->get("email");          if( $ecookie == 'none'|| !isset($ecookie) || empty($ecookie) ) {             echo mage::app()->getlayout()->createblock('core/template')->settemplate('grupondb/email-catcher/cadastroemail.phtml')->tohtml();             die;         }          // call block fill fields in checkout         echo mage::app()->getlayout->createblock('core/template')->settemplate('grupondb/email-catcher/set-email-field.phtml')->tohtml();       }  }
