Hi. Im making a flatfile chatroom. Ive been making it about a month because I dont understand the sessions. When the user enters the room he/she has to enter a nickname. But when the user enters a message the chatroom "forgets" the nickname. Ive been messing around with sessions but I cant get em to work. Session_start(); thingy is in the right place (at the top). Ive looked through about 10 diferent tutorials but they were useless. How do I make it to pass the nickname variable to multiple pages?
And please dont tell me to search google or use php.net because ive already used those.

I'd like to use session_register

<?php
if (!session_is_registered('count')) {
session_register('count');
$count = 1;
} else {
$count++;
}
?>

<p>
Hello visitor, you have seen this page <?php echo $count; ?> times.
</p>

<p>
To continue, <a href="nextpage.php?<?php echo strip_tags(SID); ?>">click
here</a>.
</p>

to put something in the session

CODE

$_SESSION['variable_name'] = "some_value";

make sure you do not do the following

CODE

$variable_name = "another value";

in any part of ur page
it will overwrite the value in ur $_SESSION['variable_name']

php sessions may be tricky thats why in order to be absolutely sure you have to completely register the session
below is a script that will register the username variable and will be accesssesible throughout the other pages..

CODE

<?php
session_start();
session_register('username');
$_SESSION['username'] = $username;
?>

by doing this then in all other pages below the page that you registered this. the variable username will be available, to test this create another page and do this

CODE

<?PHP
session_start();
var_dump($_SESSION);
?>

YOU WILL see that you have the variable username in the session array.
hope this helps

Don't use sessions. Use Cookies.

Use it something like this:

CODE

<?php

if (isset($_COOKIE["user"])){
?>

<h3>Welcome back, <span style="color: red;"><?php print $_COOKIE["user"]; ?></span></h3>

<?php
}

else {
?>

<form name="form1" method="get">
Enter your username: <input name="username" size="15">
<br><br><span style="color: blue; cursor: pointer;" onclick="form1.submit()">Submit</span>
</form>

<?php
}

if (isset($_GET["username"])){

setcookie("user",$_GET["username"],time()+9999); //set cookie to expire at that time you can experiment and add more ++ if you want
?>

<h3>Username set!</h3>
<script language="javascript" type="text/javascript">
setTimeout("window.location='./';",2000);
</script>

<?php
}
?>

Tell me if there's an error and I will correct it.

And what if user has disabled cookies in his browser?

Then it won't work. The vest way is to... well, there is actualy a best way, but... just append sessionid when calling a new scrpt:

CODE

Header('Location: somepage.php?'.SID);

Then in that file call session_start(); and use $_SESSION array to access session variables... That HAS to work
