My guess here form looking at the way you set up the locale-based routes is that the Session::get('urilang)
isn't set the first time you visit, hence the error, and is only set once you've been to a page first.
Now, I haven't yet had to deal with multilingual sites, but as far as I'm aware the way you're doing it is not the correct way. Instead think of the lang key as a URI parameter, and use the filter to validate and set it for the routes. Something a bit like the below code:
// Main and subpage - not default language
Route::group(array('prefix' => '{lang}', 'before' => 'detectLanguage'), function () {
Route::get('', 'PublicPage@homepage');
Route::get('{slug}', 'PublicPage@subpage');
});
// Main and subpage - default language
Route::group(array('before' => 'setDefaultLanguage'), function () {
Route::get('/', 'PublicPage@homepage');
Route::get('/{slug}', 'PublicPage@subpage');
});
Route::filter('detectLanguage', function($route, $request, $response, $value){
// hopefully we could do something here with our named route parameter "lang" - not really on sure the details though
// set default
$locale = 'hu';
$lang = '';
// The 'en' -> would come from db and if there is more i would of corse use in array
if (Request::segment(1) == 'en')
{
$lang = 'en';
$locale = 'en';
}
App::setLocale($locale);
Session::put('uriLang', $lang);
Session::put('locale', $locale);
});
Route::filter('setDefaultLanguage', function($route, $request, $response, $value){
App::setLocale('hu');
Session::put('uriLang', '');
Session::put('locale', 'hu');
});
I don't know if you can use a segment variable in a Route::group
prefix, but you should certainly have a go at it as it'd be the most useful.
That said, I wouldn't advise setting up default language routes that mimic specific language routes but without the language segment. If I were you, I'd set up a special root route that will redirect to /{defaultlang}/
just so you have fewer routing issues.
