CurrentVisitors

Questions answered by this recipe

How can I know how many visitors are currently surfing on my site?

Description

Copy CurrentVisitors.phpΔ to the cookbook directory and add include_once("cookbook/CurrentVisitors.php"); to config.php.

Notes

In your wiki pages, add the markup (:CurrentVisitors:) to display the number of visitors (strictly speaking "different IP addresses") that came to your site during the last MaximumNumberOfSecondsToConsiderAVisitorAsCurrent.

The counter will update only when action=browse.

I tried installing this in a specific page config file, but for some reason, the markup was not activated. It does work if I put it in my general site config.php. Caveman

Of course there is the problem of multiple users under the one IP address, so this may not work for internal sites. - Kersti

for http://free.fr change line:

      while (($file = readdir($DirectoryHandle)) == true) {
          if (is_dir($file) == false) {
            $FileFullPath = $CurrentVisitorsDirectory . '/' . $file;
            $FileStat = stat($FileFullPath);
            $FileAge = $TimeNow - $FileStat[9];
            if ($FileAge > $MaximumNumberOfSecondsToConsiderAVisitorAsCurrent) {
              unlink($FileFullPath);
            }
            else {
              $NumberOfCurrentVisitors++;
            }
          }
      }
      closedir($DirectoryHandle);

to :

      while (($file = readdir($DirectoryHandle)) == true) {
        if ($file != '.' and $file != '..') {
          if (is_dir($file) == false) {
            $FileFullPath = $CurrentVisitorsDirectory . '/' . $file;
            $FileStat = stat($FileFullPath);
            $FileAge = $TimeNow - $FileStat[9];
            if ($FileAge > $MaximumNumberOfSecondsToConsiderAVisitorAsCurrent) {
              unlink($FileFullPath);
            }
            else {
              $NumberOfCurrentVisitors++;
            }
          }
        }
      }
      closedir($DirectoryHandle);

Forceflow: If you want the script to update on edit and foxpost pages too, just change the line that says if (action='browse')
to
if (action='browse' || action='edit' || action='foxpost')
