Register and Login (Email Activation)
Posted: Tue Jul 05, 2011 10:01 pm
Hi guys I'm getting the following error from this tutorial:
Warning: mail() [function.mail]: Failed to connect to mailserver at "localhost" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set() in C:\xampp\htdocs\advertise\core\inc\user.inc.php on line 41
Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\advertise\core\inc\user.inc.php:41) in C:\xampp\htdocs\advertise\system\user\register.php on line 32
Now I guess the first part is caused by my localhost not sending e-mails correctly but what about the other one?
user.inc.php

Hi,
Thank you for registering, before you log-in you need to activate your account.
To do this simply click (or copy and paste) the link below:
http://localhost/advertise/system/user/ ... p?aid={aid}
EMAIL;
mail($email, 'Your New Account At My Site', $body, 'From:do_not_reply@betterphp.co.uk');
mysql_query("INSERT INTO `users` (`user_name`, `user_password`, `user_email`) VALUES ('{$user}', '{$pass}', '{$email}') "); echo mysql_error();
$user_id = mysql_insert_id();
mysql_query("INSERT INTO 'user_activations'('user_id', 'activation_code') VALUES ({$user_id}, '{$aid}' )");
}
?>

<?php
include('../../core/init.inc.php');
$errors = array();

{

{

}
if (filter_var($_POST['email'], FILTER_VALIDATE_EMAIL) === false)
{
$errors[] = 'The e-mail address you entered does not appear to be valid.';
}
if (empty($_POST['password']) || empty($_POST['repeat_password']))

{

}
if (empty($errors))
{
add_user($_POST['username'], $_POST['email'], $_POST['password']);
header('Location: user_cp.php');
