在symfony中的任務發送的電子郵件中包含CSS

Question

我試圖從symfony（1.4.6）任務發送HTML電子郵件，我不想從特定的模塊/動作發送整個呈現的HTML輸出，所以我正在渲染一個部分。這很好，問題是部分包含CSS引用。

當我所做的全部工作都是渲染某個特定的部分時，是否有一種很好的'symfonic'方法來將symfony任務中的CSS文件包含在HTML電子郵件中？或者是在任務內部手動構建HTML頭部/正文的唯一解決方案，使用file_get_contents(cssFile)來獲取CSS文件，然後連接渲染的部分？

任何想法，將不勝感激。

我在我的項目中遇到了同樣的問題。以下是我固定它：

1. 要保持CSS分開的，但把它內嵌在發送電子郵件之前，我們使用Emogrifier。下載源代碼並將其放入%sf_lib_dir%/vendor/emogrifier。

2. 創建一個擴展sfMailer的myMailer類。礦在下面。有幾個獨立的函數，但關鍵函數是composeAndSendPartial，它取部分名稱（作爲字符串），將所有CSS內聯插入，併發送它。我嘗試刪除特定於我的項目的所有代碼，但我可能已經留下了一些代碼。請告訴我它是否對您無效或者您有任何問題。

3. 在factories.yml文件，設置mailer:到myMailer

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

    public function composeAndSendHtml($from, $to, $subject, $body)

    }

    public function composeHtml($from = null, $to = null, $subject = null, $body = null)

    { 
    $body = preg_replace('/\<br\s*\/?\>/i', "\n", $body); //replace all <br/s> with new lines
