losing session variables

[matthew_ellis24]

I am trying to set up a php based multilanguage site. I thought about using the database for the multilingual content, but it seems more hassle than it's worth for the amount of actual writing on the site.

 

The site is www.carabusonline.co.uk. If you select a language then all fine, but as soon as you navigate away it loses the variable and resorts to english.

 

As always, any help greatly appreciated! Code below:

 

the l: in the top right is my attempt at debugging and is set to:

echo $lang;

 

as defined by session.php, which is included right at the top of the page (on every page before any HTML, with no white space included):

<?php
SESSION_START();
if (isset($_GET['lang'])) {
$lang=$_GET['lang'];
$_SESSION['lang'] = $lang;
}
if(!isset($lang)){
$lang="en";
}
?>

 

The language links are just:

<a href="?lang=es"><img src="flags/es.jpg"></a>

 

To call a page I use

		<?php
      $menu = "menu_".$lang.".html";
  include($menu);
	?>

change

 

if(!isset($lang)){
$lang="en";
}

 

to

 

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

Changing that gives me the following error (which just confuses me even more!):

 

Warning: main(menu_.html): failed to open stream: No such file or directory in /export/users/mbe/pages/carabus/index.php on line 48

ok try this more failsafe

 

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

Try:

 

<?php
SESSION_START();
if (isset($_GET['lang'])) {
$lang=$_GET['lang'];
$_SESSION['lang'] = $lang;
}
if(!isset($_SESSION['lang'])){
$lang="en";
}else{
$lang = $_SESSION['lang'];
}
?>

 

Edit: I assume that was what was meant by the last poster.

well the old code also would of worked fine with some modifications

 

<?php
SESSION_START();
$lang="en";
if (isset($_GET['lang'])) {
$lang=$_GET['lang'];
$_SESSION['lang'] = $lang;
}
else if (isset($_SESSION['lang']))
{
$lang = $_SESSION['lang'];
}
?>

excellent thanks. All sorted now. Always quite embarrassing when it's something so simple!

 

Cheers
