Dynamically change the language

[thfontaine]

Hey, I've seen your great demo of the plug-in, but I'm wondering how you dynamically build links to change the language while staying on the same page (the flags on top of the page). What I mean is if I'm on the /en/contact/ page, how can I make a /fr/contact link on the template ? Thanks in advance for your answer =)

Hey Thibault, glad you like it =)

As for looping through the URLs of the current page translations, you can use the plugin alias function, which is a superset of the framework's own alias function, taking one extra $lang parameter.

In the demo, it is basically achieved like this:

$f3=Base::instance();
$ml=Multilang::instance();
foreach($ml->languages as $lang)
  echo $ml->alias($f3->ALIAS,NULL,$lang);//<-- translated page path

As you can see, the 2nd parameter is null, because the demo routes don't hold any dynamic token.

If you have dynamic tokens, you need to fill in the 2nd parameter. And the way to go depends on your app's architecture:

• If routes parameters are identical for each language (e.g: /en/area/web and /fr/zone/web share a common language-independant web token), then just use $f3->PARAMS as a 2nd parameter, as it holds the current language parameters.
• If routes contain a translatable slug but are anyway identified by a numerical index (e.g: /en/blog/8/hey-dude and /fr/blog/8/salut-gros are translations of the same page identified by the token id=8), then you can also use $f3->PARAMS as your app will naturally performs appropriate redirections (/fr/blog/8/hey-dude => /fr/blog/8/salut-gros).
• If routes contain translatable slugs with no common index, then each controller has to generate its own translated URLs, because only it knows the values of the translated slugs.

Hope it makes sense ^^
