Email PDF Attachment with PHP Using FPDF

if you use PHPMailer

$attachment= $pdf->Output('attachment.pdf', 'S'); $mailer->AddStringAttachment($attachment, 'attachment.pdf'); 

Enjoy

I think you have a superfluous command there. You are using the string variant of the Output() command:

$doc = $pdf->Output('test.pdf', 'S'); 

Then you are performing a file_get_contents() on it:

$attachment = chunk_split(base64_encode(file_get_contents($doc))); 

It is not a file, it is a file in a string, as file_get_contents() would return if $doc was a filename.

Just reduce that down to:

$attachment = chunk_split(base64_encode($doc)); 

Then see if any more errors occur.

Create one pdf file name as testing.pdf <?php //define the receiver of the email $to = '[email protected]'; //define the subject of the email $subject = 'Test email with attachment'; //create a boundary string. It must be unique //so we use the MD5 algorithm to generate a random hash $random_hash = md5(date('r', time())); //define the headers we want passed. Note that they are separated with \r\n $headers = "From: [email protected]\r\nReply-To: [email protected]"; //add boundary string and mime type specification $headers .= "\r\nContent-Type: multipart/mixed; boundary=\"PHP-mixed-".$random_hash."\""; //read the atachment file contents into a string, //encode it with MIME base64, //and split it into smaller chunks $attachment = chunk_split(base64_encode(file_get_contents('testing.pdf'))); //define the body of the message. ob_start(); //Turn on output buffering ?> --PHP-mixed-<?php echo $random_hash; ?> Content-Type: multipart/alternative; boundary="PHP-alt-<?php echo $random_hash; ?>" --PHP-alt-<?php echo $random_hash; ?> Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 7bit Hello World!!! This is simple text email message. --PHP-alt-<?php echo $random_hash; ?> Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: 7bit <h2>Email Pdf File Attachements</h2> <p>This is something with <b>HTML</b> formatting.</p> --PHP-alt-<?php echo $random_hash; ?>-- --PHP-mixed-<?php echo $random_hash; ?> Content-Type: application/pdf; name="attachment.pdf" Content-Transfer-Encoding: base64 Content-Disposition: attachment <?php echo $attachment; ?> --PHP-mixed-<?php echo $random_hash; ?>-- <?php //copy current buffer contents into $message variable and delete current output buffer $message = ob_get_clean(); //send the email $mail_sent = @mail( $to, $subject, $message, $headers ); //if the message is sent successfully print "Mail sent". Otherwise print "Mail failed" echo $mail_sent ? "Mail sent" : "Mail failed"; ?> 

None of these worked for me...but were close. This is what worked for me and within a WordPress Plugin

function mmd_CreatePDFTest() { require(plugin_dir_path( __FILE__ ).'pdf/fpdf.php'); $pdf = new FPDF(); $pdf->AddPage(); $pdf->SetFont("Arial","B",14); $pdf->Cell(40,10, "this is a pdf example"); $pdfdoc = $pdf->Output("", "S"); $content = chunk_split(base64_encode($pdfdoc)); $filename = "test.pdf"; $file_name = "test.pdf"; $uid = md5(uniqid(time())); $mailto = "[email protected]"; $from_mail = "[email protected]"; $replyto = $from_mail = "[email protected]"; $from_name = "YOUR COMPANY NAME | PDF Test"; $subject = "send email with pdf attachment"; $message = "<Please see the attachment."; // header $header = "From: ".$from_name." <".$from_mail.">\r\n"; $header .= "Reply-To: ".$replyto."\r\n"; $header .= "MIME-Version: 1.0\r\n"; $header .= "Content-Type: multipart/mixed; boundary=\"".$uid."\"\r\n\r\n"; // message & attachment $nmessage = "--".$uid."\r\n"; $nmessage .= "Content-type:text/plain; charset=iso-8859-1\r\n"; $nmessage .= "Content-Transfer-Encoding: 7bit\r\n\r\n"; $nmessage .= $message."\r\n\r\n"; $nmessage .= "--".$uid."\r\n"; $nmessage .= "Content-Type: application/octet-stream; name=\"".$filename."\"\r\n"; $nmessage .= "Content-Transfer-Encoding: base64\r\n"; $nmessage .= "Content-Disposition: attachment; filename=\"".$file_name."\"\r\n\r\n"; $nmessage .= $content."\r\n\r\n"; $nmessage .= "--".$uid."--"; $returnpath = "-f" . $from_mail; if (mail($mailto, $subject, $nmessage, $header, $returnpath)) return true; else return false; } // function mmd_CreatePDFTest()
