multilingual website in php $_GET error

Question

i am try to make a multilingual website following this example. i made a folder language and created 2 files the en.php and the gr.php.

here are my files

language/gr.php

<?php
$lang = array(
//nav bar
'nav1' => 'Αρχική',
'nav2' => 'Δυτική Αττική',
'nav3' => 'Εκδηλώσεις',
'nav4' => 'Σύλλογοι',
'nav5' => 'Καταστήματα'
);
?>

language/en.php

<?php
$lang = array(
//nav bar
'nav1' => 'Home',
'nav2' => 'West Attica',
'nav3' => 'News/Events',
'nav4' => 'Associations',
'nav5' => 'Stores'
 );
?>

and the ini.php

<?php
session_start();

$allowed_lang = array('gr', 'en');

if (isset($_GET['lang']) === true && in_array($_GET['lang'], $allowed_lang) === true){
$_SESSION['lang'] = $_GET['lang'];
}

include 'language/' . $_SESSION['lang'] . '.php';

 ?>

when i am try to run it i get this errors

Notice: Undefined index: lang in /home/user/public_html/init.php on line 10
Warning: include(language/.php): failed to open stream: No such file or directory in /home/peerkavlos/public_html/init.php on line 10
Warning: include(): Failed opening 'language/.php' for inclusion (include_path='.:/usr/share/php') in /home/user/public_html/init.php on line 10

tried to echo the $_GET['lang']; but the results has no value

that means that the $_GET['lang'] is empty

what am i missing guys?

What if there is no lang in $_GET ? I think you should provide an initial value to $_SESSION['lang'] — Andreas, Apr 04 '17 at 18:44
so now both answers are right, which one should i accept as the right one? — vaggelis, Apr 04 '17 at 18:57
hello Andreas and thanks for your answer. you are right, its working by setting a value to $_SESSION['lang'] — vaggelis, Apr 04 '17 at 18:59

You don't have a default, so when the _GET variable is empty, you get an include on a file that doesn't exist. Maybe just hard code a default:

if (empty($_SESSION['lang'])) {
    $_SESSION['lang'] = 'en';
}
if (isset($_GET['lang']) ... ) {
}
include 'language/' . $_SESSION['lang'] . '.php';

try this

if (!empty($_GET['lang']) && in_array($_GET['lang'], $allowed_lang)) 
{
    # TRUE part
    $_SESSION['lang'] = $_GET['lang'];
    include 'language/' . $_SESSION['lang'] . '.php';
} 
else 
{
    # FALSE part
    echo "Selected Language Couldn't initialize"; 
    include 'language/en.php';
}

Hello Abdulla and thanks for your answer, its working like a charm! – vaggelis Apr 04 '17 at 18:56
This will not pull the lang from the session on subsequent page loads. I.e., if you request GR then it will give you GR on the first page and EN on the next. – Alex Howansky Apr 04 '17 at 18:57
@AlexHowansky its not page load. its language change only :P :P – Abdulla Nilam Apr 04 '17 at 18:58
"its language change only" Heh not likely on a page named `init.php`... – Alex Howansky Apr 04 '17 at 19:00
