UPDATE: I removed trim from the line you gave me… it is now only " if (isset($game[“file”])){"
it works now. Just need CSS. No idea why it works without trim but it does. LOL.
Hmmmm? I think the trim() might be converting it to a string value and therefore it is no longer a “NULL”.
So, it can not use the ISSET() in that case, but, would have to be tested against =="" instead.
Either way, CONGRATS on getting it all to work as you wanted it… Long process, but, I feel you learned
a lot thru it all.
By the way, do you have it working across your home network now? What do the others in the family
think of your now great programming skills? Smiles!
Are you saying I should change it or is it OK the way it is? 
Yes, I have learned so much. It’s helped me branch out to think of other things to learn too.
Yes, it works for everyone who is connected to the router I am running off of. There’s a higher level local I believe… See, upstairs is the main internet source, which I have a 50 or so ft cable running down here from it connecting to my router, so I can have wired connection. So myself and others who use the router down here are all good, my tablet and upstairs people are not, but they are irrelevant and so is my tablet because flash on a tablet isn’t so great. I can worry about expanding it later. THAT will be easy I am sure so no worries on that, I’ve hosted websites before…simple ones and all.
Yes, learning always makes for more learning as you progress! I am studying every day on new ways
to handle something ! But, I think that is the fun of it…
So, two things. Yes, you can just leave the IF the way you have it. No need to change it.
Also, most home user’s never think about IP addresses when doing something like you are ! ! !
So, first, on your home WIRED router, you have an IP address. That is, like 10.0.0.1 or whatever.
This means that any WIRED connection works off that. So, your computer is 10.0.0.3 or something.
Now, if you through in a wireless connection using an added on WIRELESS router, that will have a
new routing of IP addresses. Most WIRELESS routers have an option to use DHCP or not. It is ON
by default. This means that they create their own connection. So, the IP addresses that they use
are not on the same list as the main router. This means that you can not directly access it using
the same address as you would when WIRED. There are many many ways to fix this. You can just
shut off DHCP on the wireless router. This will mean that all of the wireless connections will be on
the same IP-range. (10.0.0.2 to 10.0.0.255) or whatever. Or, you can set up a VPN or use a passthru
port. I do that often as it seems to be the easiest to do. In the WIRELESS router, you have an IP
pass-through option. Sometimes it is called “IP-Forwarding”. This allows you to pass your IP of your
game, like 10.0.0.3 or whatever your IP is to a new IP number that is base on the WIRELESS router.
So, find out the IP of the WIRELESS router, which might be 192.168.1.1 or 192.168.2.1 and then just
forward the IP like 10.0.0.3 to 192.168.2.3… Then, they iPad’s would need to access 192.168.2.3 to
play the games.
Hope all that mess makes sense. It’s easier than it sounds… Depends on your ROUTER and WIRELESS
ROUTER set up…
Good luck and CONGRATS again on your success ! Are we done with this one? I will mark it solved?
Solved indeed! Yes that sounds easy. Thank you so much…
