GLobal Variables

Shit4Brains

hi,

im having trouble with getting 2 grips with global variables.

For example

index.php

<?php

$name = "Hello World";

print("<a href=\"page2.php?name=$name\">GO</a>");

this is the only way i know how to get a variable to another page.

But i want to be able to do it without having to put it in the url (for security reasons)

could some1 please give me some help.

Many thanks

The only way would be via sessions:

# Start the session
session_start();
# Check if a variable called session is created
if(!isset($_SESSION['session']))
{
# If it's not, set it to have the value active
  $_SESSION['session'] = "ACTIVE";
}

Here's a URL for more info: Click here

Hope that helps,

i dunno how i would implement that.

i read about $HTTP_GET_VARS.

but i didnt get it :mad:

could i do it with that?

At the top of each page put
session_start();

Whenever you need to set a variable use
$_SESSION['variablename'] = value

And then when you want it, just call it like a normal variable
print ($_SESSION['variablename']);

These variables by default will be passed page to page until the browser is closed. (They are still passed via the URL though, unless you force cookies - read the link I gave you for more info, I'm not very good at explaining 😉)

I'm afraid I've never used $HTTP_GET_VARS so I can't help you with that, sorry.
