BF2 Server Status Module...

Well I have been busy working on a new module that will allow bf2 fans to query thier favorite server to see who is on it, what the ping times are for each player, and hopefully be able to join to that server from the page. This script will allow you to search the database for specific servers and it will allow you to add your own server information to the database. I am still working on quite a few of the key features, but for the most part it works very well. I found the display script on another site, and integrated it into the one I was originally developing.

I am looking out for a way that I can have the database update on a regular basis, as to have it as current as possible. Does anyone know of a way, or has anyone come across a way or site that does this? Because right now the only hard variables it needs are the server name, the ip address of the server and the server port, which is usually 29900. I need a script that can parse a list and insert it into the db. Anyway, you can view it here. www.bf2online.com/modules/bf2query

It is far from done, but I think it will make a pretty good addition to a bf2 fan site.

dude! I have been wanting a module that does this :)

Any chance of getting ahold of your work in progress?

Cheers!

Good thinking m8!
Fix that TS script also! Thx for all the good work!

And tell me to Beta test!

Cheers,

Re: BF2 Server Status Module...

Heya fellas!

I am currently still developing the script. I am doing most of the coding in Dreamweaver, and haven't cleaned up the code to work with XOOPS yet. I am still adding features to it, and there is one feature that I have yet to find code for, thanks to Gamespy being the jerks that they are. I am still looking for code that will return the entire list of Gamespy servers to me in an array. Err.... at least a script that works. I have some code, but it gives me a white screen when I run it. Mithy, could you possibly take a look at this code for me and tell me what the !@#$ is wrong with it?

Thanks guys, and keep checking this post for updates.

here is a screenshot, with an explanation of some of the newer features.

Works not 100.. now two players are online but dosn't show.. but maybe it helps.

Here is the gamespy class

Here is the code that is supposed to display it on your site, but I cant get it to work.

<?php
include("include/gamespy.php"); // GameSpy Class

$GS = new GameSpy(); // Create new GameSpy-Instance
$Gamename = "battlefield2d";
$Handoff = "NqhaWF6Hms9Vao";
$Servers = $GS->GetServers("$Gamename", "$Handoff", ""); // Get the Serverlist for 'Battlefield 1942'
if(!$Servers) { // Check if an error has occurred..
echo "Error while retrieving the Serverlist!!!";
} else {
// Print the Serverlist:
foreach($Servers as $Server) {
 echo $Server["ip"] .":". $Server["port"] ."<br />n";
}
}
?>




Mithy, if you have time, could you look at this and tell me what is causing it to white screen on me? I commented out the call to the function GetServers and it works. Any and all help is greatly appreciated.

Re: BF2 Server Status Module...

Are there no PHP errors with PHP debug on?

try removing the @ from these lines:
$this->Sock = @fsockopen("tcp://$this->Host", $this->Port, &$errno, &$errstr, 2);
@stream_set_timeout($this->Sock, 2);
"When you can flatten entire cities at a whim, a tendency towards quiet reflection and seeing-things-from-the-other-fellow's-point-of-view is seldom necessary."

$Servers = $GS->GetServers("$Gamename", "$Handoff", ""); //


Have you tried removing the quotes around the parameters in the $GS->GetServers call?

Thanks guys for the quick reply. I've got a few more things to show you here.

Here is a screenshot of the admin side.
