add inline image to a message sent with swiftmailer

问题

Please excuse my php but, Im using Swiftmailer to send emails from a clients website. They've requested to add an image or two as a signature etc and so looking at the swiftmailer spec here

http://swiftmailer.org/docs/messages.html

They suggest either adding an inline image like this

$message->embed(Swift_Image::fromPath('http://site.tld/image here'))

or like this(in 2 steps)

$cid = $message->embed(Swift_Image::fromPath('image here'));

then in the emails body section add

<img src="' . $cid . '" alt="Image" />'

Both steps ive tried but to no avail. When i hit the send email button, i get this error which i dont quite know what to make of it.

Call to a member function embed() on a non-object in /home/content/78/5152878/html/4testing/erase/ask-doc-proc2.php on line 89

The only thing i added to my already working code and email was the image code directly from the example in the docs pages. This error obviously prevents the email from being sent. if i remove it then it sends emails fine. Since i need to add an image to this,

Any help is greatly appreciated. Thank you

edit: this is the portion where the email is built and sent $cid= $message->embed(Swift_EmbeddedFile::fromPath('http://myforecyte.com/dev/pic.jpg'));

->setTo( $docEmail)

->setBody("Hello" . "\r\n\r\n" .  
$fullName . " has visited MyForeCYTE.com. Upon their visit they have requested to learn more about the test. \r\n\r\n" . 
"Please visit www.ClarityWomensHealth.com to find out more about The ForeCYTE Breast Health Test, or call our customer support line at 1 (877) 722-6339.  \r\n\r\n" .
"We look forward to hearing from you. \r\n\r\n" .
"Thank You," , 'text/plain')

->addPart("Hello" . ",</b><br/><br/>" . 
"<b>" . $fullName . "</b> has visited www.MyForeCYTE.com. Upon their visit they have requested to learn more about the test. <br/>" . 
"Please visit www.ClarityWomensHealth.com to find out more about The ForeCYTE Breast Health Test, or call our customer support line at 1 (877) 722-6339.<br/> " . 
"We look forward to hearing from you. <br/><br/><br/>" . "<img src='" . $cid. "' alt='pic'/>" .

"Thank you " , 'text/html')

After all the running around i found an alternate solution. Swiftmailer allows 2 methods in which to perform the same thing.

one is the embed() function

and the other one is the attach() function

so to the code above, i removed the "embed()" since it wasn't working for me and added these 2 lines below and it works

    ->attach(Swift_Attachment::fromPath('path to image here.jpg')  
->setDisposition('inline'));

and it worked 100%

None of the answers really worked for me. I had to include inline images, using CID. What I had to do, to make it work:

$attachment = Swift_Image::newInstance($data, $filename, $mimeType)
    ->setDisposition('inline');

$cid = $message->embed($attachment); // Generates "cid:something"

Important part is using Swift_Image class. Then the image in html should be:

<img src="cid:something" ... />

I think this solution works without doing something hacky with swiftmailer (ver. 5.4.2). It is exactly how the documentation says.

Remember to test multiple email clients (gmail, thunderbird, apple mail, web clients...) if the inline images work. For example using Swift_Attachment, inline images showed in gmail, but not in some web clients. Using Swift_Image, it worked everywhere.

The accepted answer doesn't work (version tested: 5.4.2). (Mine works but could be perfected)

Instead, looking inside the "Original" (Gmail: Show Original) I've found that swiftmailer is omitting adding 2 headers to the attachment, namely:

Content-ID: <ABC123>
X-Attachment-Id: ABC123

ABC123 is the cid we have to put in the body where we want the inline to be showed:

So thanks to this question: I found the way to fix it for swiftmailer (that is even against swiftmailer documentation, but it works while theirs do not)

this is the final (ugly) code:

$attachment = Swift_Attachment::fromPath('image.jpg')->setDisposition('inline');
$attachment->getHeaders()->addTextHeader('Content-ID', '<ABC123>');
$attachment->getHeaders()->addTextHeader('X-Attachment-Id', 'ABC123');
$cid = $message->embed($attachment);
$img = '<img src="cid:ABC123"/>';
$html = "
<html>
<head>
</head>
<body>
$img
</body>
</html>
";
$message->setBody($html, 'text/html');

If you use laravel, try to add public_path() at the beginning of the path, e.g.:

<img src="<?php echo $message->embed(public_path().'/img/backend/name.jpg); ?>">
