CakePHP使用Shell cronjob的电子邮件组件

下面的代码大部分是从this dated article on the Bakery改编而来的.电子邮件正在发送,但是$controller-> set(‘result’,$results [$i]);引发以下通知：

Notice: Undefined property:
View::$webroot in
/home/jmccreary/www/intranet.sazerac.com/cakePHP/cake/libs/view/view.PHP
on line 813

PHP Notice: Undefined
variable: result in
/home/jmccreary/www/intranet.sazerac.com/cakePHP/app/views/elements/email/text/nea/task_reminder_it.ctp
on line 2

所以我没有得到传递给我的电子邮件视图的任何变量.

我该怎么做,理想地遵循蛋糕惯例？

class NotificationShell extends Shell {
    var $uses = array('Employee','Task');

    function main() {
        // run if no action is passed
    }

    function nea_task_reminder() {
        // build Task to Employee relationship
        $this->Task->bindModel(array('belongsTo' => array('Employee' => array('className' => 'Employee','foreignKey' => 'object_id'))));
        $results = $this->Task->find('all',array('conditions' => array('application_id' => 1,'completed_by_id' => 0),'contain' => array('Employee' => array('Contact','Position'))));

        $count = count($results);
        if ($count) {
            App::import('Core','Controller');
            App::import('Component','Email');
            $controller =& new Controller();
            $email =& new EmailComponent();
            $email->startup($controller);

            // send email
            $email->from = Configure::read('Email.from');
            $email->to = 'jmccreary@whatever.com';
            $email->replyTo = 'no-reply@whatever.com';
            $email->template = 'nea/task_reminder_it';
            $email->sendAs = 'text';

            for ($i = 0; $i < $count; ++$i) {
                $email->subject = 'NEA Notification: Task Reminder for ' . $results[$i]['Employee']['Contact']['full_name'];
                $controller->set('result',$results[$i]);
                $email->send();
            }
        }
    }
}
