[EP-tech] Re: Finding selected lang from configuration

Cheers Adam,
It worked like a charm! Now please allow me to asking you one more thing: I changed my title field to contain code that looks for my repository_id through the $eprint variable (which is my method's parameter), which means that the system will have to make an additional database call each time my field is accessed for each object. There's no easier method of having access to it, I suppose? (eg. directly, like I have access to the configuration via $c). 

PS. My new title-field code is as follows:

{
    name => 'title',
    type => 'virtualwithvalue',
    virtual => 1,

    get_value => sub
    {
        my ($eprint) = @_;
        if ($eprint->is_set('ml_title'))
        {
            my $repo = $eprint->repository;
            my $lang = $repo->get_langid;
# if cannot find a user language setting, I'm taking the default one 
            if (!$lang)
            {
                $lang = $c->{defaultlanguage};
            }
            my $vals = $eprint->get_value('ml_title');
            my $title = '';
            # set the default lang's text as title
            foreach my $v1 (@{$vals})
            {
                if (%$v1{'lang'} eq $lang)
                {
                    $title = %$v1{'text'};
                }
            }
# if I couldn't find a title in the user's language, get the first object's text as title 
            if ($title eq '')
            {
                $title = ${$$vals[0]}{'text'} ;
            }
            return $title;

        }
        return undef;
    }
},

It should be:

	$repository->get_lang(), which will return an EPrints::Language object, or $repository->get_langid, which will return the ID of the language.

Hi all,

I am testing the multilang field (with virtual fields for title and
abstract) and I am trying to make my virtual field return a different
title (or abstract) based on what the user's language choice is. How can
I have access to that variable on my perl configuration file? (I've
tested the default language and works as expected, but I don't find it
usable.)

Thanks all in advance.
