[SOLVED] Sessions, and maintaining a variable throughout a session

[theboyholty]

I am developing a message board and I want my users to log in before they can create threads or post replies. I have created a successful logging in section and a session is created when they enter their username and password but when they come to post a message, I want to be able to pick up their username automatically from the ongoing session they created.

 

What I want to do, therefore, is to somehow make the session record their username, so this can be dragged up from any page of the website at will so when they post messages they will be attributed to the current logged in user.

 

I have a PHP book (Sitepoint/Kevin Yank) which seems to suggest that I can change the session name to be the name of a variable ($username for example) but i can't get it to work.

 

I'm having real trouble with this, can anyone advise please?

Hi

 

Lets have a look at the code you have so far maybe will be able to help you a little better.

When they login:

session_start();
$_SESSION['username'] = $username;

echo $_SESSION['username'];

Hi

 

This session will be held on the clients browser until it is destroyed or the browser is closed.

 

so as long as you use

 

$session_start(); on every page before all your code

 

then as you have done already

<?=$session['username']?> ; or echo $session['username'] (both the same)

 

this will print to screen the username.

 

hope this helps and i have understood correct for you.

Your code is wrong.

$session_start(); on every page before all your code 

Should be:

session_start(); on every page before all your code 

and

<?=$session['username']?> ; or echo $session['username'] (both the same)

should be:

<?=$_SESSION['username'];?> or echo $_SESSION['username']; (both the same)

P.S (Browsers do not hold sessions, sessions are server side, cookies are client side.)

I already did. It is you that didn't. You told him code that is not even correct at all.
