function _htmlmail_emogrify in HTML Mail 6

Same name and namespace in other branches

1. 5 htmlmail.module \_htmlmail_emogrify()

If the Emogrifier <http://www.pelagodesign.com/sidecar/emogrifier/> exists, the CSS styles inside the the $message['body'] are inserted into the other HTML tags within the same $message['body'] as inline style attributes, based on CSS selectors.

This function is based on code in the simplenews_template module.

This emogrifier differs from that of simplenews_template in that it permits modules or users to adjoin CSS into the $message['body'] using the HTML <style> tag. The function searches the entire body for style tags, concatenates them in order of appearance in the file, then sends them to the Emogrifier script.

Note that the method modifies the $message['body'] directly, and the return value is the modified $message['body'] string as well.

Parameters

$message: The message array to be sent. This function works directly on the $message['body'].

Return value

$message['body'] The modified message body string with inlined CSS applied.
