Users Online

by: bs0d


First, you will need to create a table `users_online` in your database (and have access to one). Also, create at least 3 columns (id, ip and time) set as: int(11), varchar(15) and varchar(11).

Next, you need the code to appear in your page_header, you can save the code as a file, and include it; or just paste the code directly in your header.

Finally, you can add alot to this code, and use the table to show "who" is online as well.



$ip =            $_SERVER['REMOTE_ADDR'];
$time =             time();

$ip_check 'SELECT ip FROM `users_online` WHERE ip = \''.$_SERVER['REMOTE_ADDR'].'\'';
$ip_query mysql_query($ip_check);
$num_rows mysql_num_rows($ip_query);

$num_rows) { //if no rows, meaning no ip's in db matched theirs, we will add them.
$insert_new mysql_query("INSERT INTO `users_online` (ip, time) VALUES ('$ip', '$time')");  
//end if NOT THERE

//this means that they're already in there, so we update info.
if($num_rows 0) {
$update mysql_query('UPDATE `users_online` SET time=\''.time().'\' WHERE ip = \''.$_SERVER['REMOTE_ADDR'].'\'');
$update) die(mysql_error());
// end UPDATE

//if time now - start time > 300 then its been 5 minutes, so we delete
$delete_old mysql_query("DELETE FROM `users_online` WHERE ((".time()."-time) > 300)");
$delete_old) die(mysql_error());

//show the number of people online now.... 
$id_query = @mysql_query("SELECT * FROM `users_online`");
$users_online mysql_num_rows($id_query);

"<BR>The number of people here are : $users_online<BR>");
//users online is done....

Hi - would love some help on how to add this facility to the above code. Thanks a mil !!!!

Also, I need to add a facility to my page where I can delete users (don't want to use phpmyadmin if possible) - would prefer a script of sorts ! Any help will be greatly appreciated !

You would first need to implement a Members System. Then, once that is in place you can detect if they're signed in like this:
if($_SESSION[' logged_in'] == 1) If they are, insert their name in the users online table, if not - insert "guest&q uot;

Being able to delete users is the same. Build a script that shows all users from your members table. Then, add a check box next to each user. Have that within an HTML form, and when you submit the form, have it call upon a delete_user script that will delete based on the check boxes that were checked from the form.
