Multi-language frontend

[brandy]

Hi!

I have a very simple page, which I want to expand with 4 or more languages.
The first thing you find is the multi-language fields-page on processwire.com.

So I installed the modules and setup the different languages - now I have an tab for every language, which is fine.
But now my question is how the system recognizes the browser-language and connect it to my personally set up language?

For example: My language under Setup is called "Deutsch", how does the system know, if it´s on a browser with German on, that it should show the content of the field "Deutsch"?

Thanks a lot!

The system doesn't know that. You need to add a language switcher to your frontend so that the user can decide: https://processwire.com/talk/topic/12243-language-switcher-on-front-end/

There's also a module to auto-detect the user's language, but I've never used it: https://processwire.com/talk/topic/8733-autodetect-language/

Thanks a lot!

This one sounds good to me:
 

<?php foreach($languages as $language) : ?>
<?php if($user->language->id == $language->id) :?>
<span class="active"><?=$language->title?></span>
<?php else : ?>
 <a href="<?=$page->localUrl($language)?>"><?=$language->title?></a>
 <?php endif;?>
<?php endforeach;?>

But I got an error!
Is there something else to do, so that the system can read the languages?

Sorry guys - I overworked the code:

<?php
	foreach($languages as $language) {
		if($user->language->id == $language->id){
		 echo "<span class=\"active\">{$language->title}</span>";
		} else {
 		 echo "<a href=\"{$page->localUrl($language)}\">{$language->title}</a>";
 		}
 	}?>

Still doesn´t work, but makes more sense now ?
I also tried this one:

<?php
	foreach($languages as $language){
		echo "<a href=\"{$page->localUrl($language)}\">{$language->title}</a>";
		}
	?>

But same error here:

Error: Exception: Method HomePage::localUrl does not exist or is not callable in this context (in wire/core/Wire.php line 563)

Thanks a lot - and sorry for my bad post before!

Have you set up your local URL's on the Home page 'Settings' tab, url fields ?

It's usual to use the ISO Language (not Country) codes, eg 'de' for 'German'.

[poljpocket]

Do you have the module LanguageSupportPageNames installed (ofc no need to install, it's a core module) and enabled? It is what adds the localUrl method to Page.

remove install requirement

Thanks a lot psy and poljpocket - it was a combination of your answers!

Installing the missing module with the language codes works now!
 

Thanks a lot!
