How to send fillable pdf (filled with pdftk) via PHPMailer? - php

Question

I have a form on a website that customers fill. When user filles the form and clicks submit data is sent to a pdf(invoice) I've already created and certain spots in pdf are filled with that data. I did this using PDFTK library:
public function generate($data)
{
$filename = date("d-m-Y-His") . ".pdf";
$pdf = new Pdf('./form.pdf');
$pdf->fillForm($data)
->flatten()
->saveAs('./completed/' . $filename);
$path = './completed/' .$filename;
return $path;
}
The problem is, i dont know how to send this filled pdf via PHPMailer library, as pdf is recquired to be a string in order to work with phpmailer.
$pdf = new GeneratePDF;
$response = $pdf->generate($data);
$email = new PHPMailer();
$email->SetFrom('you#example.com', 'Your Name');
$email->Subject = 'Test';
$email->Body = 'Test';
$email->AddAddress( 'mail exmp' );
$email->AddAttachment( $response , 'NameOfFile.pdf' );
$email->Send();
And how to actually save file in cpanel server, as when i do this it doesnt work on a server.

This is not true. addAttachment() requires that you pass in a path to a local file on disk, so you could do:
$email->addAttachment(generate(), 'NameOfFile.pdf');
You can pass in a binary string using addStringAttachment(), but that's not what you're asking for here.
