* 'filename' - the filename of the file
|
|
* 'contents' - the raw binary contents of the file as a string
|
|
* and can optionally include these members:
|

* 'mimetype' - the mimetype of the file (calculated from filename if missing)
|
|
* 'contentLocation' - the 'Content-Location' header value for the file
|
|
*
|
|
* $file can also be a string, in which case it is assumed to be the filename
|
|
*
|
|
* h5. contentLocation
|
|
*
|
|
* Content Location is one of the two methods allowed for embedding images into an html email.
|
|
* It's also the simplest, and best supported.
|
|
*
|
|
* Assume we have an email with this in the body:
|
|
*
|
|
* <img src="http://example.com/image.gif" />
|
|
*
|
|
* To display the image, an email viewer would have to download the image from the web every time
|
|
* it is displayed. Due to privacy issues, most viewers will not display any images unless
|
|
* the user clicks 'Show images in this email'. Not optimal.
|
|
*
|
|
* However, we can also include a copy of this image as an attached file in the email.
|
|
* By giving it a contentLocation of "http://example.com/image.gif" most email viewers
|
|
* will use this attached copy instead of downloading it. Better,
|
|
* most viewers will show it without a 'Show images in this email' conformation.
|
|
*
|
|
* Here is an example of passing this information through Email.php:
|
|
*
|
|
* $email = new Email();
|
|
* $email->attachments[] = array(
|
|
* 'filename' => BASE_PATH . "/themes/mytheme/images/header.gif",
|
|
* 'contents' => file_get_contents(BASE_PATH . "/themes/mytheme/images/header.gif"),
|
|
* 'mimetype' => 'image/gif',
|
|
* 'contentLocation' => Director::absoluteBaseURL() . "/themes/mytheme/images/header.gif"
|
|
* );
