PHP Require makes my page blank?

Question

I have a reporting website that I created and I'm slowly adding functionality to it. I've just added a part where it is supposed to force a user to log in. It's really just to capture the users CorpID, I don't keep or record the password and it's not required.

Right now I have the login portion working. Then I'm trying to run a check to make sure that a user is logged in and if not to force them to log in. I am only doing this right now on the Admin page, which only I have access to. Here is how I've got it right now:

AdminPage.php:

<body>
    <?php
        require 'CheckLogin.php';
        include 'Menu.php';
    ?>

Other code for the page

CheckLogin.php:

<?php
    $Expiration = time() - (60*60*24*7);
    echo "You made it to here!";
    if(!isset($_COOKIE['UserName']))
    {
        if(isset($_POST['UserName']))
        {
            setcookie("UserName",$_POST['UserName'],$Expiration);
        }
        else   
        {
            echo "<script>location.href='LoginForm.php'</script>";
        }
    }
    else
    {
        if(isset($_POST['UserName']))
        {
            setcookie("UserName",$_POST['UserName'],$Expiration);
        }
        else
        {
            setcookie("UserName",$_COOKIE['UserName'],$Expiration);
        }        
    }
?>

UPDATE

Here's the Menu.php

<?php
    $AdminUsers = include 'AdminUsernames.php';
    if(isset($_COOKIE['UserName']) && in_array($_COOKIE['UserName'],$AdminUsers,TRUE))
    {
        $user = 'Admin';
    }
    else
    {
        $user = 'User';
    }
    //echo "<BR>"; print_r($_COOKIE['UserName']);
    //echo "<BR>"; print_r($AdminUsers);
?>

                }
            ?>
        </ul>
    </nav>
</div>

It's really just a standard menu and has been working fine till I added the require for the CheckLogin.php page.

All I get is a blank page when I have this require in the AdminPage.php. I don't get the echo I don't get the menu or anything.

What am I doing wrong? This isn't the first time that I've used the require, but it is the first time that it results in a blank page.

I do know that I have the expiration set to last week, I'm trying to force a re-login.

There's most likely a fatal error somewhere. Check your PHP error log. — Brad, Jul 14 '17 at 18:40
At the very, VERY top of your file add `error_reporting(E_ALL);` But if I had to guess I'd say your issue is as Mohsen described: you are trying to set cookies after flushing the page has started displaying data. — Jhecht, Jul 14 '17 at 18:45

Suggest you take out the echo, as well as adding error_reporting(E_ALL). — Ray Paseur, Jul 14 '17 at 18:53
@Jhecht I take out the `echo`, but still get a blank page. I'll see about getting the error logs. — Mike, Jul 14 '17 at 19:08
@Brad Okay, where are the PHP error log files? I thought they'd be in the same directory as PHP, but I'm not seeing them. — Mike, Jul 14 '17 at 19:13
@Mike Depends on where you configured them to be. Run `phpinfo();` in a script... that should point you in the right direction. — Brad, Jul 14 '17 at 19:15
@Brad perfect, I should have thought of that. However, the error log has nothing in it from today. Last entry was from 7/12 — Mike, Jul 14 '17 at 19:19
Just put this in the top of your script before any requires and includes... — Doug, Jul 14 '17 at 19:21
ini_set('display_errors', 1); ini_set('display_startup_errors', 1); error_reporting(E_ALL); — Doug, Jul 14 '17 at 19:21
Holy crap! I'm an idiot! I didn't put the full path of the page it should have been `require 'Helper/CheckLogin.php';` — Mike, Jul 14 '17 at 19:23
@Mike , Glad you found the issue. Probably best if you either put your comment as an answer or delete your question. — Martin, Jul 14 '17 at 19:24
@Doug You win, put that in an answer and I'll call it good. Thanks to all sorry for my stupidity. — Mike, Jul 14 '17 at 19:25
@Mike It's not stupidity. We all make such mistakes. ~15 years ago I said I would give up coding after spending 12+ hours trying to track down a misplaced semicolon, which PHP at the time insisted was on Line #-2147483648. Of course, I'm still coding. :-D — Brad, Jul 14 '17 at 19:32
@Brad I seem to have a lot of those moments! Just glad I haven't been kicked off here for showing it from time to time. :-) — Mike, Jul 14 '17 at 19:34

Using Doug's suggestion from above I found the error. In using the require I did not use the full path for the file and so it could not be opened. What that line should look like is:

require 'Helper/LoginCheck.php';

Put the following in your script before any includes or requires.

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
