Hi all,
I'm trying to add international support for a website based on the
Erlang Web 1.4.
I would like to have a couple of links on every page (the notorious
Country flags) that allow the user to set his language session variable.
What I have right now is a link like:
<li><a href="/session/language/en">English</a></li>
Where, in the session controller I do:
language(Args) ->
LanguageId = proplists:get_value(id, Args),
case language_is_supported(LanguageId) of
false ->
ok;
true ->
wpart:fset("session:lang", LanguageId)
end,
{redirect, "/"}.
The problem is that, after setting the preferred language, I would like
the user to be redirected to the page he was visiting before changing
the language. In this case the "__path" variable doesn't help because it
contains the language request and not the "previous" one.
How could I resolve this situation?
I'm probably using the wrong approach but I cannot thing to anything
else right now.
Cheers,
Roberto Aloi
