whos online?

"vijdev and 0 Guests are viewing this topic."

 

can someone help me with a pointer on how to get started with something like the above message when viewing different pages in the site...it must be page/topic specific.

is this using sessions/cookies/databases?...?

You can do this using Database. Whenever user click on particular page, increase clicks column by +1

[vijdev]

well, that would give me a hit count, how can i display current users?

[vijdev]

Anyone?

There are a ton of 'who is online' scripts posted all over the internet.

 

You use a database table. Anytime someone navigates to a page you insert/update a record for them in the table. If that person is logged in, as determined by your login code, you enter their username. If that person is not logged in, you enter them as a non-logged in guest. You can keep track of each guest by using the same kind of session that you are using for your logged in members, but save a value indicating the 'guest' status.

 

To display the values you simply get a list of the logged in usernames and count the 'guest' records from the table.

$ip = $_SERVER['REMOTE_ADDR'];

if($ip){
$res = mysql_query("select from table where ip='{$ip}' limit 1"); //ip is varchar 255

if($res){
$num = mysql_num_rows($res);

if($num == 0){
mysql_query("insert into table set ip='{$ip}' ");
}//end if num
}//end if res
}//end if ip

 

Run cron to delete ips every 5 mins or so, then just count the rows

 

..and they lived happily ever after..

The end

or instead of cron you can store a timestamp and match that against the current time, deleting any entries older than 5mins or whatever.

You still need cron for that too. I wouldnt recommend deleting rows every time a page is called, thats bad and expensive
