Lang Session not passing variable on page load

Ok appears to be fixed, all I changed was making sure all the pages are on the same level.

No it is not fixed. Anybody got any tips as to what could be causing the session to not be carried on load?

yes of course.

I am including the language session after perch at the top of the document.

   <?php
    session_start();
    $lang = 'de'; // default lang
    switch(perch_get('lang')) {
        case 'en':
            $lang = 'en';
            break;
        case 'de':
            $lang = 'de';
            break;
        // add more cases for language options here...

        default:
            if (isset($_SESSION['lang'])) {
                $lang = $_SESSION['lang'];
            }
            break;
    }
    $_SESSION['lang'] = $lang;
    ?>

Content is as documentation for second solution

<?php perch_content('Hotline - '.$lang); ?> 

Then I have page setting setup for page titles in eng/german

<?php if ($lang == 'en'){
include("inc/haupt-nav_en.php");
                    } else {
                        include("inc/haupt-nav_de.php");
                    }
                ?>

Here the english template

<?php 
    perch_pages_navigation(array(
     'levels'    => 1,
     'template' => array('en-item.html')
   ));
?>

here are the diagnostics

it's actually all working. By page load it reverts back to 'de'. That is my worry. Why is the session variable not being passed.

Yes, the session is being called right after the Perch call.

<?php include('perch/runtime.php'); ?>
<?php include('inc/language-session.php');?>
<!doctype html>
<head>
<meta charset="utf-8" />

The Dev Site is Online actually: here

Hi Drew, other than breaking the layout it is writing the selected 'lang' in the top left hand corner.

I am using a master page which has this at the top:

<?php include($_SERVER['DOCUMENT_ROOT'].'/perch/runtime.php'); ?>
<?php include('inc/language-session.php');?>
<!doctype html>

do mean with debug turned on....

Here is what I am getting in the front end:

Array
(
    [type] => 8
    [message] => Undefined variable: lang
    [file] => /is/htdocs/wp1062712_5UZW3OW5K6/lfgi/perch/templates/layouts/footer.php
    [line] => 3
)

I am also now getting this:

Array ( [ready] => 1 [userID] => 1 [userHash] => c27d9cb771b45d283a5fea2a2c1eca45 [content_expand_list] => Array ( [0] => 0 ) [csrf_token] => fb3732294c200f7a1df86e543224a46b [lang] => de )

Ok I think I may have found the problem. I am using a layout footer with the following code:

<div class="footer">
    Copyright © TORO Eventservices GmbH • <a href="<?php perch_content('Impressum - '.$lang); ?>">Impressum</a> • <a href="<?php perch_content('Arbeitnehmerueberlassung - '.$lang); ?>" target="_blank">Arbeitnehmerüberlassung</a>
</div>

The perch content is only being used for the links to other pages, in the back end, unlike all the other perch content it is only giving me one content field (content name -) not two (content name - de / content name -en).

Maybe I need to rethink how I am doing the footer layout...

Yes that appears to be it.

I have dropped the layout include, added a perch Content field and now all works as should.

Thank you Drew for prodding me in the right direction! Happy Monday to you!
