please help - save variable

[kerim]

I have a very basic question. How can I save a variable by having it set only once in a session? I have a web site that I would like to be bilingual. I have two versions of the web site stored in different folders and all I need to do is set the name of the folder in order to switch languages. However, whenever the page is reloaded it forgets that I have set the folder name.

Here is my default/index page script:

<?php

if (empty ($pg)):
$pg = "page0";
endif;

if (empty ($lg)):
$lg = "engsite";
endif;


$strPagename = $pg;
$strLanguage = $lg;
include("includes/$strLanguage/config.inc");
include("includes/$strLanguage/header.inc");
include("includes/$strLanguage/menu.inc");
include("includes/$strLanguage/$strPagename.inc");
include("includes/$strLanguage/footer.inc");


?>

As you can see, the important variable is $lg. Right now I can set it by doing a $PHP_SELF?lg=chisite <a href...> link, however, whenever a link on that resulting page is called it resets the $lg variable to the default english folder (lg=engsite).

I don't have any problem with the $pg variable because that is actually specified in all of the links, but the $lg is different because I only want it set once per session!

Thanks for your help!

Are you calling session_start()? You need to do this on every page that needs to write to/read from a session

Would it be possible to point me to an example of that command being used in a script? I don't know anything about coding - I just copy from other codes and adapt to my needs! Thanks for your help.

Here ya go:

index.php:

<?php

    $language = "English";

    session_start();
    session_register(language);

?>

<a href="page2.php">Click here</a>

page2.php:

<?php

    session_start();

    echo "Language saved is $HTTP_SESSION_VARS[language]";

?>

Thanks, I'll go give it a try!

I don't understand how to use this code to let the user change the variable. It works in the initial state, but doing a

index.php?lg=chisite

call doesn't change the language as it did before. Now it sticks to the default variable no matter what I do! Any ideas?

PS: My code looks like this:

<?php
if (empty ($lg)):
$lg = "engsite";
endif;

session_start();
session_register($lg);


if (empty ($pg)):
$pg = "page0";
endif;


$strPagename = $pg;
$strLanguage = $HTTP_SESSION_VARS[lg];

include("includes/$strLanguage/config.inc");
include("includes/$strLanguage/header.inc");
include("includes/$strLanguage/menu.inc");
include("includes/$strLanguage/$strPagename.inc");
include("includes/$strLanguage/footer.inc");

?>

I guess it is easier to just have two index pages with different sets of values. But I would still be interested in how to do this with just one page if possible. Thanks.

Unregister the variable and then register it again

Thanks. I'll play with the
session_destroy();
command. There is a lot of info on that page - especially in the discussion. It seems to be a tricky problem for lots of folks.
