Koha::Contrib::ValueBuilder::RepeatableAutocomplete - Repeatable autcomplete value-builder for Koha

VERSION

version 1.004

SYNOPSIS

  Koha::Contrib::ValueBuilder::RepeatableAutocomplete->build_builder_inline(
          {   target => '4',
              data   => [
                { label => 'ArchitektIn', value => 'arc' },
                # and more...
              ] ,
          }
      );
  }

DESCRIPTION

Koha::Contrib::ValueBuilder::RepeatableAutocomplete helps building Koha Valuebuilder Plugins. Koha is the world's first free and open source library system.

This module implements some functions that will generate the JavaScript / jQuery needed by the Koha Edit Form to enable a simple autocomplete lookup, while also working with repeatable MARC21 fields.

Please take a look at the helper modules included in this distribution, which pack all the lookup values and their configuration into easy to use functions:

• Koha::Contrib::ValueBuilder::RepeatableAutocomplete::RDA

  Values for Field 100 and 700 subfields $e and $e, creator and other agents.

Functions

build_builder_inline

Build JS to handle a short inline autocomplete lookup (data is provided to the function, not loaded via AJAX etc). The field will be inferred from the form element the value_builder is bound to.

  build_builder_inline(
        {   target    => '4',
            data      => [ { label=>"Foo", value=>'foo' }, ... ],
            minlength => 3.
        }
    );

Parameters:

• target: required

  The subfield of the MARC field into which the selected value is stored.

• data: required

  An ARRAY of HASHes, each hash has to contain a key label (which will be what the users enter) and a key value which has to contain the value to be stored in target

• minlength; optional, defaults to 3

  Input length that will trigger the autocomplete.

build_builder_inline_multiple

Build JS to handle a short inline autocomplete lookup (data is provided to the function, not loaded via AJAX etc). The selected value will be inserted into multiple subfields. The field will be inferred from the form element the value_builder is bound to.

  build_builder_inline(
        {   target_map => [
                { subfield=>'b', type=>'selected', key=>'value' },
                { subfield=>'a', type=>'selected', key=>'other' },
                { subfield=>'2', type=>'literal',  literal=>'rdacontent' }
            ],
            data      => [ { label=>"Foo", value=>'foo', other=>'FOO', }, ... ],
            minlength => 3.
        }
    );

Parameters:

• target_map: required

  A list of subfields and how to fill them with data based on the selected value.

  • subfield: the subfield to fill

  • type: how to fill the subfield. Currently we have two types: selected and literal

  • selected: If type is selected, fill the subfield with the value of the selected data mapped to the key specified here

    -item * literal: If type is literal, fill the subfield with this literal value

• data: required

  An ARRAY of HASHes, each hash has to contain a key label (which will be what the users enter) and some more keys which can be mapped to subfields using target_map entries of type selected.

  Given this target_map

    [
       { subfield=>'b', type=>'selected', key=>'value' },
       { subfield=>'a', type=>'selected', key=>'other' },
       { subfield=>'2', type=>'literal',  literal=>'rdacontent' }
    ],

  And this data

   { label=>"Foo", value=>'foo', other=>'FOO' }

  Selecting "Foo" will store value ("foo">) into subfield b, other ("FOO">) into subfield a and the literal value "rdacontent" into 2.

• minlength; optional, defaults to 3

  Input length that will trigger the autocomplete.

Usage in Koha

You will need to write a value_builder Perl script and put it into /usr/share/koha/intranet/cgi-bin/cataloguing/value_builder. You can find some example value-builder scripts in example/. The should look something like this:

  #!/usr/bin/perl
  use strict;
  use warnings;
  
  use Koha::Contrib::ValueBuilder::RepeatableAutocomplete::RDA qw(creator);
  
  return creator('de');

You than will have to enable this value_builder as a Plugin in the respective MARC21 Framework / field / subfield.
