[EP-tech] redirecting to external URLs

Hi Alan,

Do you want the user to click on a link ? Or force the page to redirect to the new location automatically??

If it's the former, you could do it in a similar way that the DOI's get processed...

e.g. in the eprint_fields.pl
        name => 'id_number',
        type => 'text',
        render_value => 'EPrints::Extras::render_possible_doi',

Then in perl_lib/EPrints/extras.pm

sub render_possible_doi
        my( $session, $field, $value ) = @_;

        $value = "" unless defined $value;

        if( $value !~ /^(doi:)?10\.\d\d\d\d\// ) { return $session->make_text( $value ); }

        $value =~ s/^doi://;

        my $url = "http://dx.doi.org/$value";
        my $link = $session->render_link( $url );
        $link->appendChild( $session->make_text( $value ) );
        return $link;

This will take the value entered into the id_number field, and render it as a link on the screen, prefixing it with the appropriate http url leader etc...

So anyone know how I should be redirecting the user to an alternative URL based on some processing in a Screen action?

As it is, I'm setting the url in the action by

$self->{processor}->{redirect_to_url} = "http://example.org";

and then checking for it in

sub redirect_to_me_url {
                return $self->{processor}->{redirect_to_url};

It seems a little too hacky!
