This is my first real attempt at coming to StackExchange and I wanted my question to be as relevant as possible. Basically, I am following along in the O'Reilly book to Learn PHP, MySQL, Javascript, etc. and I'm a bit stuck on Chapter 16's authentication protocol. Basically the author wants us to just put the CSS and JS in the echo <<<_END statements, I'm trying to put it so they can still be kept separate in their external file.
My problem is, when I load the PHP file, absolutely nothing comes up. Not even a title. I was concerned this might have something to do with the fact that I'm running WebMatrix and an IIS Express server for development, but I have been able to run other, much smaller echo <<<_END statements fine when I went to test them.
Below is the code, if anyone has input I would be very grateful.
<?php
$firstname = $lastname = $username = $password = $age = $email = "";
if (isset($_POST['firstname']))
{
$firstname = fix_string($_POST['firstname']);
}
if (isset($_POST['lastname']))
{
$lastname = fix_string($_POST['lastname']);
}
if (isset($_POST['username']))
{
$username = fix_string($_POST['username']);
}
if (isset($_POST['password']))
{
$password = fix_string($_POST['password']);
}
if (isset($_POST['age']))
{
$age = fix_string($_POST['age']);
}
if (isset($_POST['email']))
{
$email = fix_string($_POST['email']);
}
$fail = valide_firstname($firstname);
$fail .= valide_lastname($lastname);
$fail .= valide_username($username);
$fail .= valide_password($password);
$fail .= valide_age($age);
$fail .= valide_email($email);
