I have a site that is translated in 3 languages. English, Korean and Chinese. The users can click on what language they want to view the site on the splash page. The problem I've been running into is if they do not enter through the splash page or type in the exact URL for the homepage including the specific language they get a page with no text. Is there a way that I can make the site default to english if the user enters my site through a backpage? The programmer who did my site has this snippet of coding on most of the pages.

PHP Code:

<?php 
session_start();
if($_SESSION['lang']=='english'){
include_once "english.php";
}
else if($_SESSION['lang']=='chinese'){
include_once "chinese.php";
}
else if($_SESSION['lang']=='korean'){
include_once "korean.php";
}
$_SESSION['getwill_id']="";
?>

This code is found on the homepage.

PHP Code:

<?php 
session_start();
$lang=trim($_GET['lang']);
if($lang=='e'){
$_SESSION['lang']="english";
}
else if($lang=='c'){
$_SESSION['lang']="chinese";
}
else if($lang=='k'){
$_SESSION['lang']="korean";
}

if($_SESSION['lang']=='english'){
include_once "english.php";
}
else if($_SESSION['lang']=='chinese'){
include_once "chinese.php";
}
else if($_SESSION['lang']=='korean'){
include_once "korean.php";
}

?>

check for the session being blank or not existing and set a default language

You could also take the default at the users browser default language, so if its chinese it automatically shows in chinese..

As well at the rest, fairly easy code. PM me if you would like it done for you

You can use this for your homepage code block:

PHP Code:

session_start();
 
switch (trim($_GET['lang']))
{
  case 'c':
    $_SESSION['lang'] = 'chinese';
    include_once('chinese.php');
    break;
 
  case 'k':
    $_SESSION['lang'] = 'korean';
    include_once('korean.php');
    break;
 
  default:
    $_SESSION['lang'] = 'english';
    include_once('english.php');
    break;
} 


And this for your other page block:

PHP Code:

session_start();
 
switch (@$_SESSION['lang'])
{
  case 'chinese':
    include_once('chinese.php');
    break;
 
  case 'korean':
    include_once('korean.php');
    break;
 
  default:
    include_once('english.php');
    break;
}
 
$_SESSION['getwill_id'] = '';
