number of users per channel via pfc\'s response

[vlzvl]

Hello and congrats for this work,
I know how to read the currently online users via:

Code: Select all

  $info  = new pfcInfo( md5(yada) );
  $users = $info->getOnlineNick(foo);
  $num_users = count($users);

but this gives me 2 options to get it dynamically:
1) via the old fashioned way of a second ajax (i will not do such a thing,
pfc is already a heavy resource for a free server)
2) via pfc's response class, somehow

So how can i instruct the pfc to call the above code the
time it constructs its response, so to return that little tiny
number (instead of a resource-waster second ajax)

I dont know if there's already such a feature (modifying
responses by PHP and handle them by javascript) or
where to look

thank you for a needed masterpiece

HI,

If this information is going to be presented outside the chat, example (main site page) then you need a second ajax call, but if this is going to be in the chat page then it can be done in pfcclient.js and present it in any part of the chat page itself...

hope this helps..

regards.

hello and thanx,
I understood the file pfcclient.js is reponsible for handling the 'responses'.

More of it, the function 'handleResponse(cmd,resp,param)' is responsible
for the 'frequent' chat updating (the 'update' command - is coming every X time,
check your 'refresh_delay')

The problem is that when 'cmd' comes as 'update' it doesnt holds any params
(in 'resp' or 'param' functions params)

Is there's a way to 'program' the 'update' command in PHP? So to call whatever
php code we want, then return it in our way (or pfc) and handling it via
'handleResponse' ?

tx for the help

EDIT:
i want to change part of the very same page (eg. a div), no bothering with other pages.

EDIT2:
I think i found the solution to this.
I just found the 'commands' list as PHPs in /src/commands.
I opened the one named 'update.class.php' and find that on
line 73 i can 'program' the JS for 'handleResponse'.
This one:

Code: Select all

$xml_reponse->script("pfc.handleResponse('update', 'ok', 'test');");

With this knowledge i can program whatever i want in
'update' command, including the one mentioned in first entry.
thank you for your help

Hi,

You dont need to touch that object , if you only want to show how many people there are in the chat just gather the nick ID and count them, and place it somewhere in the chat container..

That if I understood your first question,

So how can i instruct the pfc to call the above code the
time it constructs its response, so to return that little tiny
number (instead of a resource-waster second ajax)

But is nice that found what you wanted to do..

regards.

thank you,
I really didnt wanted to dig in there and deploy code that it will be ruined
when i update the next phpfreechat
But i didnt find any other way to do that in the -frequency- i wanted to do.
(eg. in every pfc's refreshing, to avoid second calls mainly)

"You dont need to touch that object , if you only want to show how many people there are in the chat just gather the nick ID and count them, and place it somewhere in the chat container.."

I understand that its too much for a single number (online users) but what if i wanted to execute big-time
operations? it would be really nice to do such a thing while's in pfc's ajax call.
About the counting you mentioned, yes im doing pretty much this thing, but every X seconds ('refresh_delay')
its refreshed.
If there's another way, i would be gladly following it, but for now it seems i just updated the default pfc's 'update'
command
How about implementing hooks? for example "hook_preupdate" to call your thingies instead of going down there?

Hi,

Every time someone logs in , the nick ID get update in the same refresh rate...
So everything is update for everybody , you just need to find where the nickids are gathered and inject them in the part of container you wanna show them..

Thats why I said if this were to be outside the chat , then you would need to call with ajax the php you mentioned above..

ok regards.
