Question

I have problems with php multilanguage. I’m using function *check_lang* and it works fine in one page, but once I go to another page the $_SESSION[‘lang’] variable $lang turns back into default (en). What is the problem?

<?php

    function check_lang() { 
    if(isset($_GET['lang'])
        {
        $lang = $_GET['lang'];
        $_SESSION['lang'] = $lang
        }

    if (!isset($_SESSION['lang'])) { 
        $lang = 'en'; 

    } else { 
        $_SESSION['lang']=$lang; 
      } 

    //directory name 
    $dir = 'languages'; 
    return "$dir/$lang.lng"; 
    } 

    ?>

You have to:

session_start();

At the top of each of your scripts in which you want to use session variables.
