php : email sending failed with more than one attachment - php

Question

I am trying to implement mail functionality in php, its working fine with single attachment, but problem is when I am trying to send more than one attachment, its not working. I am using php mail() function for sending emails, I am trying to attach a PDF and an Image file. If PDF attach then Image won't attach, if Image attach then PDF won't attach. Any thoughts where I'm doing wrong?
$header .= 'From: test <noreply#test.ae>' . "\r\n";
$header .= "MIME-Version: 1.0\r\n";
$file = '1.png'
$displayname = '1.png';
$file_size = filesize($file);
$handle = fopen($file, "r");
$content = fread($handle, $file_size);
fclose($handle);
$content = chunk_split(base64_encode($content));
$uid = md5(uniqid(time()));
$name = basename($file);
$filepdf = '1.pdf'
$displaynamepdf= '1.pdf';
$file_sizepdf = filesize($filepdf);
$handlepdf = fopen($filepdf, "r");
$contentpdf = fread($handlepdf, $file_sizepdf);
fclose($handlepdf);
$contentpdf = chunk_split(base64_encode($contentpdf));
$name = basename($file);
$header .= "Content-Type: multipart/mixed; boundary=\"".$uid."\"\r\n\r\n";
$header .= "This is a multi-part message in MIME format.\r\n";
$header .= "--".$uid."\r\n";
$header .= "Content-type:text/plain; charset=iso-8859-1\r\n";
$header .= "Content-Transfer-Encoding: 7bit\r\n\r\n";
$header .= $message."\r\n\r\n";
$header .= "--".$uid."\r\n";
$header .= "Content-Type: application/octet-stream; name=\"".$displayname."\"\r\n"; // use different content types here
$header .= "Content-Transfer-Encoding: base64\r\n";
$header .= "Content-Disposition: attachment; filename=\"".$displayname."\"\r\n\r\n";
$header .= $content."\r\n\r\n";
$header .= "Content-Type: application/octet-stream; name=\"".$displaynamepdf."\"\r\n"; // use different contentpdf types here
$header .= "Content-Transfer-Encoding: base64\r\n";
$header .= "Content-Disposition: attachment; filename=\"".$displaynamepdf."\"\r\n\r\n";
$header .= $contentpdf."\r\n\r\n";
$header .= "--".$uid."--";
if (mail($to, $subject, "", $header)) {
return 'sent';
} else {
return 'not sent';
}

You have $file and $filepdf both set to '1.png'. Set $filepdf="1.pdf" so that the rest of the header is correct.

Here is the code for multiple attachments in mail function..
I have created the function for multiple attachment . and check this.
/*
* Function Name: sentMail
* Scope : Sent Mail Function with CC , BCC and Attachment files..
* Input : Recipient Name => $recipientName // (Required)
* Recipient MailId(Many) => $recipientMailId // (Required & Array Format)
* Subject Content => $subjectContent // (Required)
* Message Content => $messageContent // (Required)
* Sender MailId => $senderMailId // (Required)
* Sender Name(Many) => $senderName // (Required)
* Recipient CC MailId => $recipientCCMailId //(Optional & Array Format)
* Recipient BCC MailId => $recipientBCCMailId //(Optional & Array Format)
* Attachment Files => $attachmentFiles //(Optional & Array Format)
* Output : Sent mail to the Recipient.

Answer 4

i was facing the same issue. The problem is with mime boundary. Don't add "--".$uid."--"; after every attachment. Adding boundary before content type of attachment is enough.
