PHP email form with attachments not working - php

Question

I'm trying to use a PHP email form I found online that supports attachments, with a bit of extra code, but it's not working, I get a message saying "Sent", but no emails (I checked spam already).
Here is the php file:
function multi_attach_mail($to, $subject, $message, $senderMail, $senderName, $files){
$from = $senderName." <".$senderMail.">";
$headers = "From: $from";
// boundary
$semi_rand = md5(time());
$mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";
// headers for attachment
$headers .= "\nMIME-Version: 1.0\n" . "Content-Type: multipart/mixed;\n" . " boundary=\"{$mime_boundary}\"";
// multipart boundary
$message = "--{$mime_boundary}\n" . "Content-Type: text/html; charset=\"UTF-8\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" . $message . "\n\n";
// preparing attachments
if(count($files) > 0){
for($i=0;$i<count($files);$i++){
if(is_file($files[$i])){
$message .= "--{$mime_boundary}\n";
$fp = #fopen($files[$i],"rb");
$data = #fread($fp,filesize($files[$i]));
#fclose($fp);
$data = chunk_split(base64_encode($data));
$message .= "Content-Type: application/octet-stream; name=\"".basename($files[$i])."\"\n" .
"Content-Description: ".basename($files[$i])."\n" .
"Content-Disposition: attachment;\n" . " filename=\"".basename($files[$i])."\"; size=".filesize($files[$i]).";\n" .
"Content-Transfer-Encoding: base64\n\n" . $data . "\n\n";
}
}
}
$message .= "--{$mime_boundary}--";
$returnpath = "-f" . $senderMail;
//send email
$mail = #mail($to, $subject, $message, $headers, $returnpath);
//function return true, if email sent, otherwise return fasle
if($mail){ return TRUE; } else { return FALSE; }
}
$message = "Customer Contact"
. "\n" . "Name: " . $_POST['fullName']
. "\n" . "Email: " . $_POST['email']
. "\n" . "Phone: " . $_POST['phone']
. "\n" . "Current Phone: " . $_POST['currentPhone']
. "\n" . "Address: " . $_POST['address']
. "\n" . "Retailer: " . $_POST['retailer']
. "\n" . "Product Type: " . $_POST['productType']
. "\n" . "Specific Item: " . $_POST['item']
. "\n" . "Purchase Date: " . $_POST['purchaseDate']
. "\n" . "Invoice Number: " . $_POST['invoiceNumber']
. "\n" . "Issue: " . $_POST['issue']
. "\n" . "How did the issue happen?: " . $_POST['how']
. "\n" . "When did the issue occur?: " . $_POST['when']
. "\n" . "Have you done anything to try correcting the issue?: " . $_POST['customerTry'];
$to = 'someEmail#gmail.com';
$from = $_POST['email'];
$from_name = $_POST['fullName'];
//attachment files path array
$files = $_FILES['files'];
$subject = 'Customer Contact From Service Form';
$html_content = $message;
//call multi_attach_mail() function and pass the required arguments
$send_email = multi_attach_mail($to,$subject,$html_content,$from,$from_name,$files);
//print message after email sent
echo $send_email?"<h1> Mail Sent</h1><br>".$message:"<h1> Mail not SEND</h1>";
My form looks like this:
<form NOVALIDATE action="processContact.php" enctype="multipart/form-data" id="claimsForm" method="post" name="claimsForm">
..lots of fields...
<div class="form-group">
<label class="control-label claimsForm-field-header" for="customerTry">Photos:</label>
<input type="file" id="files[]" name="files[]" multiple="multiple" />
</div>
<input class="green-btn" id="ss-submit" name="submit" type="submit" value="Submit">
</form>
The function came with the form I downloaded, so I don't think there is a problem with it. I've been playing around with the code and trying different things, but no luck (I'm not a PHP guy).
EDIT:
Based on the suggestion below, I tried using phpMailer, following the example they have, here is my php file now:
/**
* PHPMailer simple file upload and send example
*/
$msg = '';
$message = "Customer Contact"
. "\n" . "Name: " . $_POST['fullName']
. "\n" . "Email: " . $_POST['email']
. "\n" . "Phone: " . $_POST['phone']
. "\n" . "Current Phone: " . $_POST['currentPhone']
. "\n" . "Address: " . $_POST['address']
. "\n" . "Retailer: " . $_POST['retailer']
. "\n" . "Product Type: " . $_POST['productType']
. "\n" . "Specific Item: " . $_POST['item']
. "\n" . "Purchase Date: " . $_POST['purchaseDate']
. "\n" . "Invoice Number: " . $_POST['invoiceNumber']
. "\n" . "Issue: " . $_POST['issue']
. "\n" . "How did the issue happen?: " . $_POST['how']
. "\n" . "When did the issue occur?: " . $_POST['when']
. "\n" . "Have you done anything to try correcting the issue?: " . $_POST['customerTry'];
$to = 'murtorius#gmail.com';
$from = $_POST['email'];
$from_name = $_POST['fullName'];
//attachment files path array
$files = $_FILES['userfile'];
$subject = 'Customer Contact From Service Form';
if (array_key_exists('userfile', $_FILES)) {
// First handle the upload
// Don't trust provided filename - same goes for MIME types
// See http://php.net/manual/en/features.file-upload.php#114004 for more thorough upload validation
$uploadfile = tempnam(sys_get_temp_dir(), sha1($_FILES['userfile']['name']));
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
// Upload handled successfully
// Now create a message
// This should be somewhere in your include_path
require 'php-mailer/PHPMailerAutoload.php';
$mail = new PHPMailer;
$mail->setFrom($from, $from_name);
$mail->addAddress($to, 'TEST');
$mail->Subject = $subject;
$mail->msgHTML($message);
// Attach the uploaded file
$mail->addAttachment($uploadfile, 'Photos');
if (!$mail->send()) {
$msg .= "Mailer Error: " . $mail->ErrorInfo;
} else {
$msg .= "Message sent!";
}
} else {
$msg .= 'Failed to move file to ' . $uploadfile;
}
}
I changed the input file field name to 'userfile[]', but I get this:
Warning: sha1() expects parameter 1 to be string, array given in /home/zucora/service.zucora.com/processContact.php on line 35
Warning: move_uploaded_file() expects parameter 1 to be string, array given in /home/zucora/service.zucora.com/processContact.php on line 36
If I change the name to 'userfile' (without []) I get a blank screen and no email.
