Re: [PHP] Users Online?
Why all this mess for such a simple thing? All you need is to allocate the last activity timestamp with userid in the users table, add 'last_activity' column to the users table then update it with every page load at the administration panel. Then all you need to do in order to print out the current logged in users is to SELECT `username` FROM `users` WHERE `last_activity` time() - 60*15 60*15 means that users which had an activity during the last 15 minutes will be shown as logged in ;) This is the way I would do that if you have no session handling system.

Hi everyone, I have a login system that allows a user to login to my control panel, is there an easy way so that I can tell how many users / what users are logged into my system?

I assume there is since many community applications (IE bulletin boards) show logged in users. It's probably easiest if you use a database for session handling, but you can probably do it it other ways as well. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Your best bet is to add two fields to your table(s)-- datetime logged in and datetime logged out. You'll need to work out a way to expire someone's login if they appear to be logged in too long (they closed their brower or left it open but forgot about the tab for your site). Upon login, you could perform a query of the table(s), looking for the number of records where the logout field is empty. Paul -- Paul M.

RE: [PHP] Users Online?
Chris, If it were me (and let me warn you, there's probably 100 different ways to do this), but If I was using a table to log them into a control panel (CP) of sorts, I'm sure you have other DB querries to handle the CP stuff it self, correct? Well if your already taking the time to create a DB connection on each page of that CP, why not just make a field that updates an active status, and/or add this to Pauls suggestion of logged in/out times, then every page they visit updates that time to show they are still active. Then do something like my bank does and set a time limit on each page, that if another page on the site isn't visited in so many seconds, you force them to log out. (you could even throw something in that asks the user if they want to stay logged in, cuz that'd be a nice feature) :) Not sure if this was what you were lookin for but just an idea.

Re: [PHP] users online
Hi,
Try this. I am assuming that you have already
fetched the name of the user who is online, either
from the database or from session or whatever. I am
assigning the variable $uname with that user online.
I've used javascript to display the name in the
textbox. Here goes the code. Simple.isn't it??
script language=JavaScript
function enterMe(who)
{
document.frmpok.txtpok.value=who;
}
/script
?
$uname=David;
?
form name=frmpok action=#
input type=button name=butpok value=Enter
onclick=enterMe('? echo $uname;?');
input type=text name=txtpok value=
/form

?php echo $name;?
What am I not getting here?...
Maybe you want it to happen on the CLIENT which wouldn't be PHP?...
FORM ACTION=# METHOD=GETINPUT TYPE=SUBMIT VALUE=Who Am I?
onClick=JavaScript:showname('?php echo $name;?'); return true;/FORM
Your showname function in JavaScript will probably have to use the
'innerHtml' value or something like that to alter the text you want to
change. I forget exactly what it is, but this isn't a JavaScript list
anyway.

[PHP] users online
Hi, I have been searching the archives with little luck so I need a reminder here, I remember a little while ago someone asked how to implement the users online functionality that some sites have...now i have been asked to do exactly that but with a small twist: instead of displaying xx number of users online they want me to display all the usernames who are online with a link to their profile. I have a few ideas on how this can be done, but I would like advise from people who have already done this or thought of doing it (i think there was also a class that does something like this i'll check while waiting for a reply from you guys) so i can compare it with my ideas (which are in the infancy stage ;-) ) Thanks, Ryan -- No virus found in this outgoing message.

Al you need to do when displaying the 'users online' info is getting al profiles with the 'last seen' record on a time between now and x minutes ago (depending on what you consider to be an 'online' user). If you're using a database like mysql or postgresql for profile storage, use a field type that the database software can handle internaly, this can speed up the query. regards, Ewout -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
