setting a variable that stays from page to page

Hi,

I am just wondering, how can I define a variable that can be recalled from different pages without having to be defined again?

Thank you!

Yes! use sessions!

Try searching google for "php sessions tutorial", sessions are really useful for that kind of stuff...

Hope this helps!

$_SESSION['var_name'] = 'value';

hmmm.. let me tell you what I am wanting to do, and then you can tell me if this is the way to do it or not.

I want to offer users a choice to view a webpage with the horizontal nav bar at the top locked or unlocked.. Meaning the div with the nav bar will be with position: fixed or position: relative... I am imagining I will just add a style tag via html if $lock=1 or if $lock=0 and define if it's fixed or relative...

Right now all my webpages are importing the nav bar via include (using the same code for each page)...

So the question is... how can I refresh the present page by clicking a link (the lock link) without having to tell it what that page is?

secondly, is this session variable thing the way to go to do this?

thank you for the kindness.

Not really sure what you are really wanting but a session variable once set follows the user the entire thime they are on the site. To play with session variables write these short scripts and run them.
anyname.php

<?php
session_start();
$loginUsername="myself";
$_SESSION['username']=$loginUsername;
echo "<a href='next.php'>next page</a>";
?>

next.php

<?php
session_start();
echo "Well ".$_SESSION['username']." lets go to the next page.";
echo "<a href='page3.php'> Go to even another page.</a>"; 
?>

page3.php

<?php 
session_start();
echo "Well {$_SESSION['username']} your name is still the same. Guess what lets go to even another page. ";
echo "<a href='page4.php'>Page 4</a>";
?>

page4.php

<?php
session_start();
echo "Well {$_SESSION['username']} your name is still the same. See how sessions work!";
?>
