I also have a php-Nuke forum with a chat module installed (the most amazing chat app I've ever seen). The chat only works in Nuke, and only up to php5.3.
Is PHPNuke itself still maintained?
I really thought they had stopped development 10-15 years ago. At least back then it was known mostly for security problems.
Ultimately I'd like for all visitors to be able to see the queue/history, guests to be able to request one song in x minutes, and registered users to be able to request at variable rates depending on a status assigned to them. I'd like this validation to correspond to the same interface that my chatters use so that they don't need multiple accounts. And, it needs to be compliant to at least php5.6.
That's something you'll need custom programming for. SAM doesn't support different request timeouts on it's own, but will only ever provide one fixed timeout per IP address.
What I want to know is, what are other people using for user-validation for requests? Is wordpress the way to go? Is there something better (newer, easier) that people are using?
99.999% of all people that use requests do so with the unmodified default templates of SAM.
There's maybe a handful of people using fhrsam or another custom wordpress request system (I've been involved with developing 2 and have only seen one more that was developed by a user on their own)
The FHRSAM thing as created by Festerhead (and still hosted by me) does support the soon-to-be-outdated PHP5.6, but not the current PHP7.1/7.2.
I'm not really keen on fixing that plugin as it's code quality is rather low. It's better than the old SAM templates, but still does so many nasty tricks that are absolutely unneccessary.
