PHP mail() function not sending email

Question

I am attempting to send an email using the mail() PHP function. I had it working until I attempted to give it a subject of \"User registration\", t

Answer 1

I'm using this code on most of my projects:

$subject = 'subject';
$message = 'message';
$to = 'user@gmail.com';
$type = 'plain'; // or HTML
$charset = 'utf-8';

$mail     = 'no-reply@'.str_replace('www.', '', $_SERVER['SERVER_NAME']);
$uniqid   = md5(uniqid(time()));
$headers  = 'From: '.$mail."\n";
$headers .= 'Reply-to: '.$mail."\n";
$headers .= 'Return-Path: '.$mail."\n";
$headers .= 'Message-ID: <'.$uniqid.'@'.$_SERVER['SERVER_NAME'].">\n";
$headers .= 'MIME-Version: 1.0'."\n";
$headers .= 'Date: '.gmdate('D, d M Y H:i:s', time())."\n";
$headers .= 'X-Priority: 3'."\n";
$headers .= 'X-MSMail-Priority: Normal'."\n";
$headers .= 'Content-Type: multipart/mixed;boundary="----------'.$uniqid.'"'."\n";
$headers .= '------------'.$uniqid."\n";
$headers .= 'Content-type: text/'.$type.';charset='.$charset.''."\n";
$headers .= 'Content-transfer-encoding: 7bit';

mail($to, $subject, $message, $headers);

Answer 2

I would suggest to use PHP_EOL instead of \r\n or \n as the line break would then be determined by your environment...

$headers  = 'MIME-Version: 1.0' . PHP_EOL;

etc.. hoping this might finally solve your problem!

Answer 3

On your 4th line you're using ' that handles everything inside of it as a string so change

$headers .= 'Content-type: text/html; chareset=iso-8859-1\r\n';

To:

$headers .= "Content-type: text/html; charset=iso-8859-1\r\n";

and as mentioned in the comments change chareset to charset

Edit:

if your sending a txt/html mail you have according to documentation to set mime in the headers too so try this

    $to = $this->post_data['register-email'];
    $message = 'Hello etc';

    $headers  = 'MIME-Version: 1.0' . "\r\n";
    $headers .= "Content-type: text/html; charset=iso-8859-1\r\n";
    $headers .= 'From: Website <admin@example.com>' . "\r\n";
    mail($to, 'User Registration', $message, $headers);

If it still doesn't work you could try to debugg your code, simply add

error_reporting(E_ALL);
ini_set('display_errors', '1');

on top of the page, and take it from there, and if you still can't solve it by yourself post it here and I'll do my best to help ya out.
