Okay, so I think I’ve resolved it and I wasn’t too far off originally…

 

Rather than messing with the redirect_to_me_url () function, the answer (from examining https://github.com/eprints/eprints/blob/3.3/perl_lib/EPrints/ScreenProcessor.pm#L313) appears to be to just set the desired destination as redirect in the screen processor hash.

 

e.g.      $self->{processor}->{redirect} = “http://wiki.eprints.org”;

Thanks Matt, but it’s the latter I’m after – sending the user automatically to a new location with parameters  based upon the values submitted in a form.

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 $url = "" href="http://dx.doi.org/$value">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…

 

 

Cheers

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!

Cheers,
