Dynamic Forum Signature

[joebloggs1987]

Hello.

 

I need help creating a dynamic forum signature.

 

I need the signature to display how many people are online at www.rotarychat.com if that is possible.

 

I only know basic php, so this is a bit out of my knowledge.

 

Thankyou.

What part you stuck on ?

if your using sessions, you could do something like this:~

 

<?php
session_start();
function countUsersOnline()
{
$count = 0;
$handle = opendir(session_save_path());
if ($handle == false) return -1;
while (($file = readdir($handle)) != false)
{
	if (preg_match("/^sess/i", $file))
	{
		if(file_exists($file)) $count++;
	}
}
closedir($handle);
return $count;
}
?>

 

To display

<?php
$usercount = countUsersOnline();
echo $usercount; 
?>

Look at this http://php-login-script.com/

 

as a note i have NOT looked at the source so it could be quite bad, but should atleast should get you started

If you have a look at www.rotarychat.com and quickly login (does not require any registration), you will be able to see in the top left hand corner a 'whos online'.

Basically i just want this in a forum signature.

 

Script is http://bernsteinforpresident.com/software/the-hablator

 

Im just not sure how to put it in a forum sig.

U require more than basic PHP.

Looks like u will need CURL (too pass login info) / preg_match (to get the info from the page/scrape)

 

but scraping pages in this fashion take time, so on a forum signature this can cause a bad situation. if a page/thread you become very active in, loads up.

 

as each posting will perform the scrape (get page contents).

 

Yer best bet is to see if the site owner can create a counter files, or who's online file for such use.

Or to cache the results, and perform the scrape every once in awhile.

Hmmm... ok

 

I am the site owner of www.rotarychat.com if that makes a difference.

 

The users online are stored in a text file.

 

For example, with one person online, the text file contains the following...

 

91a04520c5a7e08a2b49627b0e8fdc58 rxsprint 08:32 AM 06/02/2009 1243895565 Windows MSIE 60.242.66.61 1243895590.98

 

The whole script uses text files rather than a mysql database.

 

 

EDIT:

This is what displays it on the chat page...

 

<div id="users"><a href="#" id="userlistlink"><img src="img/triright.gif" class="tri" style="border: none"><img src="img/tridown.gif" style="display:none; border: none" class="tri"><?php echo $language_whos_online; ?></a>

<div id="userlist" style="display:none;"><?php loadusers(); ?></div></div>

 

EDIT: Also...

I took another look.

Its in the javascript, u can get a list of users from This Link

 

But this seems more like a site for sale than a php project, and if thats the case u shud look into freelancers
