retaining variables

[jwoo]

I am using a variable in one .php script on a site ($pmac) and I need to use it in another script on another .php file on the same site.

Problem is when I jump to that page the $pmac variable is gone it seems to be empty. What am I doing wrong or can this be done even?

Thanks

I read something about global but I tried it and seemed not to work maybe I just dont understand it too well yet.

Anyone can shed some lite I would be appreciative.

I'm fairly newbie myself, but I know that a variable has to be past along to the next page.

Whether you do that via POST or GET is up to you.

for example, GET would be

script.php?variablename=variablevalue

any help?

I read those too but didnt get the hang of those yet neither.. so I guess I am still lost. Thanks though for the fast reply.

You could do as pablodelapena said.
Assuming you're not using forms, in your script do this:
$link = "http://www.yoursite.com/nextscript.php?var=" . $var
Then do whatever you want with the link (probably redirect the user to that page). Then you'll have your variable in that page! 🙂

Alternatively you could store the var in a cookie (on the user's pc-NOT for sensitive data!), or store it in a session (on the server).

setcookie("nameofcookie", $var);

We didn't set a lifetime, so it'd get deleted when the browser is shut - probably fine (unless it's a user's customisation like a chosen site skin or something). You would use it in the next script like:
$_COOKIE['var']

For sessions you'd do this in your first script:

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

On your next script simply start the session again with session_start(), and then you can use the variable with $_SESSION['var'].

Hope that helped.
