Session problem

RickyD77

ok heres the idea.
i want to have a language choice

i have set a session variable in a lib.php file this file is include in every page

session_start();
$g_langue = "en";
session_register("g_langue");

now i just want a button to change the en for a fr

but i can figure how

thx

I think you need something along these lines:

lan.php

session_start();

// create session (if not exist)
if(!session_is_registered('lan') {
 session_register('lan');
}

// set the value
// check for the existence of a form value (lan)
if(!isset($_GET['lan'])) {
 $lan = "en";
} else {
 $lan = $_GET'[lan'];
}

im not sure

all i need its to switch between "en" and "fr"

but with a <a href> it works only one time

my session was always start cause i include my lib file in my header

all i need its to switch the $g_langue value

One thing to note is - when you update a session variable you should reload the page also. use the header function to do that:

header("location: page.php");

you must put the header function before any other headers are sent out !!
