hi, i have a current working registration page, (the code is below), how do i make it so when they click register it checks to see if its a valid email address, if u cannot help me can u give me a link to a website. this registration form creates files instead of using a mysql database so i need the code to work with this registration page.
<?php
$errors = array();
if(isset($_POST['login'])){
$username = preg_replace('/[^A-Za-z]/', '', $_POST['username']);
$email = $_POST['email'];
$password = $_POST['password'];
$c_password = $_POST['c_password'];
if(file_exists('users/' . $username . '.xml')){
$errors[] = 'Username already exists';
}
if($username == ''){
$errors[] = 'Username is blank';
}
if($email == ''){
$errors[] = 'Email is blank';
}
if($password == '' || $c_password == ''){
$errors[] = 'Passwords are blank';
}
if($password != $c_password){
$errors[] = 'Passwords do not match';
}
if(count($errors) == 0){
$xml = new SimpleXMLElement('<user></user>');
$xml->addChild('password', ($password));
$xml->addChild('email', $email);
$xml->asXML('users/' . $username . '.xml');
header('Location: register-complete.php');
die;
}
}
?>
