Problem with the auth plugin example

Drew McLellan said:

Does your app include an autoloader?

I'm afraid I don't know what that is, so I suppose not.

Yes. At present I have two of the same file, both with that class declaration, copied from the example, one in /home/dave/sites/site1/perch/addons/plugins/auth/my_system/auth.php and one in /home/dave/sites/site1/perch/plugins/auth/my_system/auth.php

I've tried one and then the other and both.

What I've done (just for now) is paste that class into the top of /home/dave/sites/site1/perch/core/lib/PerchUsers.class.php, which gives me the expected result in that no login is required. (Although the class is printed at the top of the admin page).

OK thanks. I've deleted auth folder from /home/dave/sites/site1/perch/plugins. (Had that there just to try it). Also deleted the class my_system_auth_plugin from /home/dave/sites/site1/perch/core/lib/PerchUsers.class.php.

So I have /home/dave/sites/site1/perch/addons/plugins/auth/my_system containing auth.php containing the example code with a class of my_system_auth_plugin, and the last two lines of config.php are:

define('PERCH_AUTH_PLUGIN', 'my_system');
require(__DIR__. '/../addons/plugins/auth/my_system/auth.php');

The 500 I'm getting logs as:

Sure: /home/dave/sites/site1/perch/addons/plugins/auth/my_system/auth.php

class my_system_auth_plugin extends PerchAPI_AuthPlugin
{
    public function log_user_in($username, $password)
    {
        //make request to check username and password
        return [
            'email' => 'admin@example.com',
            'role'  => 'admin',
        ];
    }

    public function resume_session()
    {
        //make request to check username and password
        return [
            'email' => 'admin@example.com',
            'role'  => 'admin',
        ];
    }

    public function log_user_out()
    {
        return true;
    }
}

Sure, I'm working with another dev (who bought the licence) and not sure if I should show the domain, so have hidden:

On the off chance it's somehow related: if I move a file about.html in site root to about/index.php, I can't view the About page by browsing 'about/' -I have to go to 'about/index.php'. (I'm new to all this :)

Wait, that's not the whole of your auth.pho file is it? It has a <?php tag too, right?

Um, it didn't exactly have one. I feel like a real silly billy. (massive PHP noob error)

Thank you very much for your help :)
