generating a un-registered user a random guest number when accessing chat room

[adt2007]

hi there

 

my social community is begging that i enable guests to login to the chat room. i want to do it but im not entirely sure how, this is how it works:

 

when my REGISTERED user access chat the jscript parameter loads their username:

 

<APPLET NAME="DigiChat"

CODEBASE="http://www.yourserver.com/DigiChat/DigiClasses/"

CODE="com.diginet.digichat.client.DigiChatApplet"

WIDTH="200" HEIGHT="100" ALIGN="MIDDLE"

ARCHIVE="CLIENT.JAR"

<PARAM NAME="siteID" VALUE="1000">

<PARAM NAME="cabbase" VALUE="Client.cab">

<PARAM NAME="background" VALUE="FFFFFF">

<PARAM NAME="textcolor" VALUE="000000">

<PARAM NAME="nickname" VALUE="$user->user_info.user_username">

<APPLET>

 

"$user->user_info.user_username" obviously places the user's username in and it automatically connects...

 

but i want to allow guests, so i need something that literally "if "$user->user_info.user_username" doesnt exist, create guestname" in the param field.

 

and guest names would be "Guest" with random numbers after it such as Guest7957, Guest8377, Guest9255... any ideas?

 

cheers

What value does $user->user_info.user_username have when it doesn't "exist"?

 

Assuming "not existing" means empty, one could do something like this:

 

$nickname = empty($user->user_info.user_username) ? "Guest".mt_rand(1000, 9999) : $user->user_info.user_username;

But that provided code means anyone get's in hope you no that....

This is how it works mate

 

<?php

$username="";

if(empty($username)){

$username='Guest'.rand(000000,999999).$username;
}else{

$username=$username;
}

echo $username;

?>

<?php

$username="";

if(empty($username)){

$username='Guest'.rand(000000,999999).$username;
}else{

$username=$username;
}

echo $username;

?>

 

how is that going to go into my applet though?

ive just realised, my applet code isnt in the page source, its actually in a .js file that is loaded <script> onto the page. will it still work?

session example

 

<?php session_start();
$_SESSION['username']=$user->user_info.user_username;
if(empty($_SESSION['username'])){
$_SESSION['username']='Guest'.rand(000000,999999).$_SESSION['username'];
}else{
$_SESSION['username']=$_SESSION['username'];
}
?>

not unless your server parses .js files as PHP (highly unlikely). you'll need to copy/paste the contents of the .js file into the PHP file to use PHP.
