CakePHP 2：电子邮件模板中的Html助手 [英] CakePHP 2: Html Helper in Email Template

问题描述

我有一个艰难的时间试图找出为什么我不能使用$ this-> Html-> url在我的电子邮件CakePHP 2.0的模板。 Helpers数组在视图中为空。这是设计还是我缺少某些东西？

文档和迁移指南中没有提及任何东西。

跟踪类似：

  include  -  APP / View / Emails / html / admin / users_recover.ctp，第1行
 View :: _ render（） -  CORE / Cake / View / View.php，line 598 
 View :: render（） -  CORE / Cake / View / View.php， 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，第186行
 UsersController :: admin_login（） -  APP / Controller / UsersController.php，第101行
 ReflectionMethod :: invokeArgs内部]，线?? 
 Controller :: invokeAction（） -  CORE / Cake / Controller / Controller.php，第476行
 Dispatcher :: _ invoke（） -  CORE / Cake / Routing / Dispatcher.php，第106行
 Dispatcher :: dispatch（） -  CORE / Cake / Routing / Dispatcher.php，第88行
 [main]  -  APP / webroot / index.php，第96行
  pre> 
 
 
这是我发送辅助邮箱的函数：
  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（UsersController :: sendRecoverEmail中的错误：无法发送电子邮件至：{$ email}。 
 return false; 
} 
 return true; 
} 
  
最后，视图：
 < p>您是否在进入您的<？php echo Configure :: read（'Site.title'） ？>帐户？< / p> 
 
<？php $ url = $ this-> Html-> url（array（'action'=>'recover'，'controller'=>'users'，$ recoveryKey ），true）; ？> 
 
< p>如果这是正确的，< a href =<？php echo $ url;？>>点击此处恢复您的访问权限并创建新密码。 ; / a>< / p> 
 
< p>如果您忽略它，您的密码将保持不变。< / p>您是否尝试过设置CakeEmail渲染器帮助器，然后再调用send（）方法，然后再尝试设置CakeEmail渲染器帮助器。

  $ cakeEmail-> helpers（'Html'）
  pre> 
 
 
点击 http://api20.cakephp.org/file/Cake/Network/Email/CakeEmail.php#method-CakeEmailhelpers  
 
 
 
 DRY）选项可以在您的模板中加载HtmlHelper：
 <？php 
 $ htmlHelper = > Helpers-> load（'Html'）; 
 
 $ url = $ htmlHelper-> url（array（'action'=>'recover'，'controller'=>'users'，$ recoveryKey），true）; 
？> 
  
 
I'm having a tough time trying to figure out why I can't use $this->Html->url in the templates for my emails for CakePHP 2.0. The Helpers array is empty in the views. Is this by design or am I missing something?

The docs and migration guide don't mention anything around this.

The trace looks like:
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
Here is the function that I have sending the recovery email:
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;
}   
And finally, the view:
<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>

解决方案
Have you tried setting CakeEmail renderer helpers before calling send()?
$cakeEmail->helpers('Html')
Bit more info at http://api20.cakephp.org/file/Cake/Network/Email/CakeEmail.php#method-CakeEmailhelpers

Another (anti-DRY) option could be to load HtmlHelper inside your templates:
<?php
$htmlHelper = $this->Helpers->load('Html');

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