phpmailer str_replace multiple times - php

Question

I have the following setup:
$message = file_get_contents('./site/resources/external/template.html');
$message = str_replace('[name]', $email['name'], $message);
$message = str_replace('[password]', $password, $message);
require './site/resources/external/PHPMailer/PHPMailerAutoload.php';
$mail = new PHPMailer();
$mail->SMTPSecure = 'tls';
$mail->Username = "mymail";
$mail->Password = "mypassword";
$mail->AddAddress($email);
$mail->FromName = "Marc";
$mail->CharSet = 'UTF-8';
$mail->Subject = "Din nye adgangskode";
$mail->msgHTML($message, dirname(__FILE__));
$mail->Host = "smtp.live.com";
$mail->Port = 587;
$mail->IsSMTP();
$mail->SMTPAuth = true;
$mail->From = $mail->Username;
$mail->Send();
However when i try to send it, it does not send.
However when i do like this:
However when i do the following:
$mail->msgHTML(str_replace('[password]', $password, file_get_contents('./site/resources/external/template.html')), dirname(__FILE__));
it sends without a problem.
So how can i add multiple variables to my template ?

Answer 1

Although I don't see how the variable substitution of $message could be breaking your code, there is a multiple replacement form of str_replace that uses array arguments:
$mail->msgHTML(
str_replace(
array('[password]','[name]'),
array( $password, $email['name'] ),
file_get_contents('./site/resources/external/template.html')
),
dirname(__FILE__)
);
I suspect something else is wrong with your code, but this might be useful.
