重定向在控制器中不起作用

Question

我的代码在这里......

public function sendemail(){    

    $this->loadmodel('Template');
    $this->Template->recursive = -1;
    $temp = $this->Template->find('all',array('order'=>'rand()','limit'=>20));
    $this->Employe->recursive = -1;
    $person = $this->Employe->find('all',array('conditions'=>array('DAY(Employe.dob)' => date('d'),'MONTH(Employe.dob)' => date('m'))));
    $count = count($person);        
    if(!empty($person)){
    for($i=0; $i<=($count-1); $i++)
        {
            $template = $temp[$i]['Template']['description'];           
            $find = array("Name", "test1", "test2" ,"test3");
            $replace   = array($person[$i]['Employe']['name'], $person[$i]['Employe']['skype'], $person[$i]['Employe']['email'],$person[$i]['Employe']['gender']);          
            $template = str_replace($find, $replace ,$template);            
            $email = new CakeEmail();
            $email->config('smtp');
            $email->from(array('hris@planetwebsolution.com' => 'HR, Planet Web Solution'));
            $email->to(array('hr@planetwebsolution.com'));
            $email->emailFormat('html');
            $email->subject('HAPPY BIRTHDAY  '.$person[$i]['Employe']['name'].'....');
            $bodyText= $template;
            $email->send($bodyText);            
            unset($email);
        }
    } 
    return $this->redirect(array('controller' => 'staticpages', 'action' => 'index'));

}

当我点击sendemail功能时，它应该进入http://example.com/staticpages/index，但它显示带有此网址的空白页面。 http://example.com/staticpages/sendemail

任何人都可以帮助我吗？ 提前谢谢..
