PHPMailer attachment, doing it without a physical file

Question

So:

// Setup mail class, recipients and body
$mailer->AddAttachment('/home/mywebsite/public_html/file.zip', 'file.zip');
The AddAttachment function has four arguments:

AddAttachment(PATH_TO_FILE, FILENAME, ENCODING, HEADER_TYPE)

I used to use xmail() and when I added a attachment here, I passed the filename and the content, that should be in it.

Like this:

$xmail->addAttachment('myamazingfile.pdf', $content);

How can I make it work the same way, so when i call AddAttachment() from the PHPmailer class, I can either pass the same or something like it, so I dont need to have a actual file on my server to send?

Answer 1

AddStringAttachment($string,$filename,$encoding,$type)

eg

$mail = new PHPMailer();
$mail->AddStringAttachment($string,$filename,$encoding,$type);

Answer 2

since that AddAttachment() function is expecting a path rather than byte data, you should do a php convert to temp file function and then pass that path string into your function

$prefix     = 'ConvertMediaArgs_'.time().'_';
$tempfile   = tempnam( $this->tempdir, $prefix );

// Args file create failure: kill script with TEMPFILEFAIL error
if($tempfile === false) {
    die('file could not be created');
}

// Write args as Key=Val (\n) to file
$fullpath   = $this->tempdir.$tempfile;
$content    = $someContent // <---------------- this is your file's data
$handle     = fopen( $tempfile, "w");
fwrite( $handle, $content );

// $fullpath is the path you wanna pass to your function
$xmail->addAttachment( $fullpath, $content );
