Notes:

• The Silverstripe 2.4 compatible version of the module is still available in the ss24 branch
• The Silverstripe 3.x compatible versions are still available in the 2.x branches. (see version info)

A database field type that allows the storage of multiple discrete values in a single database field. This also provides form fields for entering multiple values in a simple manner

• MultiValueTextField - displays a text field. When data is entered, another text field is displayed directly beneath. Subsequent data entry triggers more text fields to appear
• MultiValueDropdownField - displays a dropdown field. When a value is selected another dropdown field is displayed.

Within templates, the field can be iterated over as per a data object set. The property $Value is available as a Varchar type, and other typical properties such as $FirstLast etc are inherited from ViewableData.

Data is stored in the database in a serialized PHP format. While this is not ideal for searching purposes, some external indexing engines (eg the Solr module) are aware of the field type and will index accordingly.

Version info

This version of MultiValueField supports Silverstripe 4.0.0

Older versions of Silverstripe are supported on minor version branches below

• Silverstripe 3.1+ compatible version

Installation

composer require symbiote/silverstripe-multivaluefield

Basic Usage

As with all DB fields

private static $db = array(
    'Keywords' 	=> 'MultiValueField',
);

To make use of the field on the frontend, you can loop over the Items property

<% loop $Keywords.Items %>
    <p>$Key $Value</p>
<% end_loop %>

In this case, $Value is a Varchar object, so you can call all relevant string field methods on it, such as $Value.Raw, $Value.LimitWordCount etc etc.

Note that to have the $Key value available as something other than an integer, use the KeyValueField field type to populate the field.

You can set the key and value placeholder values of the KeyValueField in your field like this:

$kvf = KeyValueField::create(
    'MultiChoiceAnswer',
    'Multiple Choice Answers'
);
$kvf->setValueFieldPlaceholder('Value');
$kvf->setKeyFieldPlaceholder('Label');
