custom validation rule(s)

Ok do you have an understanding of the PHP and CI namespace please

I'd say "somewhat" which is why I used the existing namespace rules as a guide. I suspect that the user guide at https://www.codeigniter.com/user_guide/l...stom-rules assumes you know what to do with regard to namespaces.

Thanks @luckmoshy, I was over specifying the namespaces. I just needed

PHP Code:

<?php
namespace Config;

class ClubRules
{ 


In my new class file and just update the $ruleSets array with:

PHP Code:

ClubRules::class, 


So I'd say that for clarity the user guide is missing that "namespace XXX;" line from its example.
