Passing Player Data to MOTD

(1/3) > >>

Wully616:
Hello,

Is there any way to pass player or server  data from the MOTD to the URL which it loads, much in the same way the sv_loadingurl can grab the players steamID and the map name?


--- Code: ---If you run sv_loadingurl "http://mywebsite.com/loadingpage.php?steamid=%s&mapname=%m" then the following $_GET values are available to PHP.

    $_GET["steamid"] is the player's steam community id.
    $_GET["mapname"] is the current map name. EX: gm_construct

--- End code ---

My lua is more or less non existent so please forgive me, now that uni's nearly over I'm hoping to learn though.

I've looked through the documentation for ulib/ulx and the gmod wiki, I've seen like the getUser, game.GetMap() ply:SteamID() functions and stuff but in all honestly I'm not 100% what I'm looking for.
I need a function to grab the players steamID  when they execute the command "ulx motd", save it to a variable so it may be appended to the motd URL.
Which PHP should be able to grab and I can do whatever with as I've done for my loading screen.

--- Code: ---function ulx.showMotdMenu()
local window = vgui.Create( "DFrame" )
if ScrW() > 640 then -- Make it larger if we can.
window:SetSize( ScrW()*0.9, ScrH()*0.9 )
else
window:SetSize( 640, 480 )
end
window:Center()
window:SetTitle( "ULX MOTD" )
window:SetVisible( true )
window:MakePopup()

local html = vgui.Create( "HTML", window )

local button = vgui.Create( "DButton", window )
button:SetText( "Close" )
button.DoClick = function() window:Close() end
button:SetSize( 100, 40 )
button:SetPos( (window:GetWide() - button:GetWide()) / 2, window:GetTall() - button:GetTall() - 10 )

html:SetSize( window:GetWide() - 20, window:GetTall() - button:GetTall() - 50 )
html:SetPos( 10, 30 )
if not isUrl then
html:SetHTML( ULib.fileRead( "data/ulx_motd.txt" ) )
else
local mapname = game.GetMap() //Get the map name
local steamid = ply:SteamID() //get the players steam ID
html:OpenURL( url.."?steamid="..steamid.."&mapname="..mapname) //append data onto URL for php to grab
end
end
--- End code ---

Would the above function work? Or is there any easier way to do this?

Megiddo:
First off, that number is not a regular steamid, but a 64-bit steamid. You'd use this function to get that. Also there is no "ply" object in the code to grab the ID from. So you should be using "LocalPlayer():SteamID64()". Other than that it looks like it should work.

Wully616:
Thanks Megiddo!
One problem I'm having with it now though is that it doesn't get the localPlayers steamID64 when first joining the server and the motd opens. I would guess this is because it isn't the player thats technically executing the command?

Other than that, once the player types !motd in chat or ulx motd it opens and passes the steamID64 over perfectly.
I can change the steam64ID into the nicer looking one with a script that's no problem.

Megiddo:
Okay, so it's calling the function before the player is created, probably. To fix that you'd need to wait to bring up the MOTD until the player is created, but that's not a simple modification. Another (less robust) idea would be bringing the MOTD up ten seconds after a player joins.

Megiddo:
Another idea is having the server inform the player what their steamid is. It seems silly to need to do that, but it would work.
