Hi Jean-Marie

                Try something like this (note that this is just typed into the email, so will have lots of errors).

#this is the render_value function that’s set in the field config

$c->{render_authors_with_images} = sub

{

                my ($repo, $field, $value, $allangs, $nolink, $eprint) = @_;

                my $frag = $repo->xml->create_document_fragment;

                foreach my $person (@{$value})

                {

                                $frag->appendChild($repo->call(‘render_author_as_link’, $repo, $person));

                }

                return $frag;

};

$c->{render_author_as_link} = sub

{

                my ($repo, $author) = @_;

                $name = EPrints::Utils::make_name_string($author->{name});

                my $url = "" $name->{ppn});

                my $image_url = $repo->call(‘staff_image_url’, $name->{ppn});

                my $frag = $repo->xml->create_document_fragment;

                my $a = $repo->xml->create_element(‘a’, href ="" $url);

                $a->appendChild($repo->xml->create_text_node($name));

                $frag->appendChild($a);

                my $img = $repo->xml->create_element(‘img’, src ="" $image_url);

                $frag->appendChild($img);

                return $frag;

};

$c->{staff_link_url} = sub

{

                my ($ppn) = @_;

                return ‘http://myorganisation.org/staff/’ . $ppn;  #build as required

};

$c->{staff_image_url} = sub

{

                my ($ppn) = @_;

                return ‘http://myorganisation.org/staff/images/’ . $ppn . ‘/profile_thumbnail.jpg’;

}

Hi again Adam,

How to add a hyperlink and especially an image associated with this link? Which method to use?

Thank you.

Jean-Marie

Ah yes, thank you. I understood better the mechanism ! It is sometimes (often) difficult to debug Eprints :-)

You need to return a dom object from a render function.   Here are a couple of replacement lines:

 

 

                ….

                                push @authors, EPrints::Utils::make_name_string( $_->{name} );

                …

                return $repo->xml->create_text_node(join(‘; ‘, @authors));

 

Move the return to the bottom of the function, aswell.  At the moment it’s in the loop.  Also, I think your render_value config line may belong outside the fields section.

Subject: [EP-tech] Render_value help

 

Hi all,

I want to modify the rendering field creators to add an ID ("ppn") as indicated in this page. So I defined in my eprint_field.pl this configuration:

{
            'name' => 'creators',
            'type' => 'compound',
            'allow_null' => 1,
            'multiple' => 1,
            'fields' => [
                          {
                            'sub_name' => 'ppn',
                            'type' => 'text',
                            'input_cols' => 10,
                            'allow_null' => 1,
                          },
                          {
                            'sub_name' => 'name',
                            'type' => 'name',
                            'hide_honourific' => 1,
                            'hide_lineage' => 1,
                            'family_first' => 1,
                            },
                          },
                          {
                            'sub_name' => 'id',
                            'type' => 'text',
                            'input_cols' => 20,
                            'allow_null' => 1,
                          },
                        ],
                        'input_boxes' => 4,
                         'render_value' => 'idref',
...

}

but I can not write the code to display the authors' data in the following form:
"Name, First name (ppn) and  Name, First name and  Name, First name (ppn)" for example.

I started writing things like this:
$c->{idref} = sub
{

my ($repo, $field, $value, $allangs, $nolink, $eprint) = @_;
my @authors;

for( @{ $eprint->value( "creators" ) } )
{

      push @authors, {
        author => EPrints::Utils::make_name_string( $_->{name} ),
      };
return \@authors;
}

}

but it does not work....

Any help or example will be welcome!

Jean-Marie
