CakePHP 2：電子郵件模板中的Html Helper

Question

我在試圖弄清楚爲什麼我無法在我的電子郵件CakePHP 2.0的模板中使用$ this-> Html-> url。 Helpers數組在視圖中是空的。這是由設計還是我錯過了什麼？

文檔和移植指南沒有提到任何事情。

跟蹤的樣子：

include - APP/View/Emails/html/admin/users_recover.ctp, line 1 
View::_render() - CORE/Cake/View/View.php, line 598 
View::render() - CORE/Cake/View/View.php, line 365 
CakeEmail::_render() - CORE/Cake/Network/Email/CakeEmail.php, line 1300 
CakeEmail::send() - CORE/Cake/Network/Email/CakeEmail.php, line 933 
UsersController::_sendRecoverEmail() - APP/Controller/UsersController.php, line 186 
UsersController::admin_login() - APP/Controller/UsersController.php, line 101 
ReflectionMethod::invokeArgs() - [internal], line ?? 
Controller::invokeAction() - CORE/Cake/Controller/Controller.php, line 476 
Dispatcher::_invoke() - CORE/Cake/Routing/Dispatcher.php, line 106 
Dispatcher::dispatch() - CORE/Cake/Routing/Dispatcher.php, line 88 
[main] - APP/webroot/index.php, line 96 

這裏是我發送恢復電子郵件的功能：

private function _sendRecoverEmail($email, $recoverKey) { 
    App::uses('CakeEmail', 'Network/Email'); 
    $cakeEmail = new CakeEmail(); 
    $cakeEmail->config('default'); 
    $cakeEmail->to($email); 
    $cakeEmail->subject('Recover Your '. Configure::read('Site.title') . ' Account'); 
    $cakeEmail->template('admin/users_recover'); 
    $cakeEmail->viewVars(array(
     'recoverKey' => $recoverKey, 
    )); 
    try { 
     $cakeEmail->send(); 
    } catch (Exception $e) { 
     trigger_error("ERROR in UsersController::sendRecoverEmail: couldn't send email to: {$email}."); 
     return false; 
    } 
    return true; 
} 

最後，認爲：

<p>Have you been having difficulty getting into your <?php echo Configure::read('Site.title'); ?> account?</p> 

<?php $url = $this->Html->url(array('action' => 'recover', 'controller' => 'users', $recoveryKey), true); ?> 

<p>If this is correct, <a href="<?php echo $url; ?>">click here to recover your access and create a new password.</a></p> 

<p>Your password will remain the same if you ignore it.</p> 

Answer 1

A）確保在控制器中包含相關的幫助程序（在本例中爲Html）

B）使用this book reference檢查/設置Html助手手動工作。

Answer 2

您在調用send（）之前是否嘗試過設置CakeEmail渲染器助手？在http://api20.cakephp.org/file/Cake/Network/Email/CakeEmail.php#method-CakeEmailhelpers

另一個（防乾燒）選項

$cakeEmail->helpers('Html') 

位的詳細信息可加載的HtmlHelper裏面的模板：

<?php 
$htmlHelper = $this->Helpers->load('Html'); 

$url = $htmlHelper->url(array('action' => 'recover', 'controller' => 'users', $recoveryKey), true); 
?>
