Question

我正在尝试从symfony（1.4.6）任务发送HTML电子邮件，我不想从特定模块/操作发送整个呈现的HTML输出，所以我渲染部分。这一切都很好，问题是部分包含CSS引用。

是否有一种很好的'symfonic'方法可以在symfony任务的HTML电子邮件中包含CSS文件，当我所做的只是渲染特定的部分？或者是在任务中手动构建HTML头/体的唯一解决方案，使用file_get_contents(cssFile)获取CSS文件，然后连接渲染的部分？

任何想法都会受到赞赏。

我在项目中遇到了同样的问题。以下是我修复它的方法：

为了使CSS保持独立，但在发送电子邮件之前将其内联，我们使用Emogrifier。下载源代码并将其放入%sf_lib_dir%/vendor/emogrifier。
创建一个扩展sfMailer的myMailer类。我的下面。有几个单独的函数，但关键函数是composeAndSendPartial，它采用部分名称（作为字符串），插入所有CSS内联，并发送它。我试图删除所有特定于我的项目的代码，但我可能已经留下了一些。如果它不适合您或者您有任何问题，请告诉我。
在factories.yml中，将mailer:设置为myMailer

<强> myMailer.class.php：

<?php
class myMailer extends sfMailer
{
  /**
   * Creates a new message with 2 bodies:
   * * 1 with $body and MIME type text/html.
   * * 1 with $body and tags stripped with MIME type text/plain. Stipped <br/>, </p>, and </div> tags and replaced with \n

将CSS包含在symfony中从任务发送的电子邮件中
