PHPMailer, AddStringAttachment and Data URI Scheme

I have converted the contents of a canvas element to data (URI Scheme) using toDataURL() ($contact_image_data) and I want to send this via email as an attachment. This is currently how I have PHPMailer set up:

$contact_image_data="data:image/png;base64,iVBORw0KGgo[...]";
$filename="test.png"; 
$encoding = "base64"; 
$type = "image/png";
$mail->AddStringAttachment($contact_image_data, $filename, $encoding, $type);

I am wondering if this is actually possible, and if so, what steps I am missing.

I can send an email, attach a file named “test.png” which contains the contents of $contact_image_data, but it doesn’t actually create an image.

Any help would be much appreciated.

Samuel.

Solution

  • Yes it should be possible. Are you calling toDataURL() with the 'image/png' MIME type so it knows how to output it?

    Try breaking your script into two components - make sure you really have a PNG then try mailing it.

    For example, will test.png open on your computer when written?..

    <?php
$contact_image_data="data:image/png;base64,iVBORw0KGgo[...]";
$fp = fopen('test.png', 'w');
fwrite($fp, $contact_image_data);
fclose($fp);
?>

    Hope that helps a bit!
