| Documentation for the installation |
| of UserOnline 2.1 |
| |
+----------------------------------------+

In order to setup the UserOnline Script, you must do the following:

1. unpack ZIP
2. Edit config.php3
3. Upload all files
4. Insert the UserOnline code into the pages, that the current
number of users should be shown

+----------------------------------------+
After you've unpacked the zip, you have to edit the variables in the config.php3.

<?php

// Timeout - After this time the users will
// be deleted (in minutes)
$timer = 100;

// Name of the file where all the data, about
// the user's activity will be saved
$filename = "$DOCUMENT_ROOT/useronline/log.txt";

?>

+----------------------------------------+
There are two possibilities to setup the UserOnline script on your homepage:

A. HTML: [img]your/path/to/useronline.php4[/img]
If you chose the HTML version, the current number of users won't be shown,
but the user will be logged.

B. PHP: <?php include("your/path/to/useronline.php4"); ?>
Please consider that when you insert the PHP code, the current amount of
users online will be outputted.
The pages that you insert this code into have to be PHP 4 compatible

+----------------------------------------+
If you encounter any bugs while using this
script, then please write those into our
forum:http://scripts.w3secrets.com/forum/

Gör en tom fil som heter log.txt och sedan kan du bara ha <?php include("your/path/to/useronline.php4"); ?> för att skriva nummret. Jag använder det och det funkar bra.
