I followed a tutorial on youtube from betterphp about using MySQL and PHP to create a login and register system for a web site. I followed as the tutorial showed, up to part 3. The problem is when i have the php/sql code in the file, it wont let the html code show up on the screen. So all i get is a blank page. But when i remove the php code the html code shows up and i see what i want to. Below is my script used:
<?php
include('core/init.inc.php');
if (isset($_POST['username'], $_POST['password'], $_POST['repeat_password'])){
if (empty($_POST['username'])){
$error[] = 'The username cannot be empty.';
}
if (empty($_POST['password']) || empty($_POST['repeat_password'])){
$errors[] = 'The password cannot be empty.';
}
if ($_POST['password'] !== $_POST['repeat_password']){
$errors[] = 'Password verification failed.':
}
if(user_exists($_POST['username'])){
$errors[] = 'The username you entered is already taken.';
}
if (empty($errors)){
add_user($_POST['username'], $_POST['password']);
$_SESSION['username'] = htmlentities($_POST['username']));
header('Location: protected.php');
die();
}
}
?>

That suggests you made a syntax error somewhere and do not have php set up to tell you about it, so it just dies. If you have access to the php.ini file you can set error_reporting = E_ALL and display_errors = On for more info ...

I fixed the miss-spelling that element pointed out. I also edited the ini file to display errors, and it doesnt say anything. I still get a blank screen.

Did you restart Apache after editing php.ini ?

Can you post the full code as it is now ?
Also does your php set up work ? you could try a test file like
<?php
echo 'test';
?>
to check this.
Sorry for the patronising questions, I have to ask

My PHP works, i've been working on other pages for my website other than the login/register. Below is the code as is now.
<?php
include('core/init.inc.php');
if (isset($_POST['username'], $_POST['password'], $_POST['repeat_password'])){
if (empty($_POST['username'])){
$error[] = 'The username cannot be empty.';
}
if (empty($_POST['password']) || empty($_POST['repeat_password'])){
$errors[] = 'The password cannot be empty.';
}
if ($_POST['password'] !== $_POST['repeat_password']){
$errors[] = 'Password verification failed.';
}
if(user_exists($_POST['username'])){
$errors[] = 'The username you entered is already taken.';
}
if (empty($errors)){
add_user($_POST['username'], $_POST['password']);
$_SESSION['username'] = htmlentities($_POST['username']));
header('Location: protected.php');
die();
}
}
?>

I had it with one )
Also php should have told you about this error
Something is stopping your errors from being displayed. You will find it very hard to debug / develop with hidden errors.
