README

Extends a DataObject with a mutil value field to store arbitrary settings in it.

Requirements

SilverStripe CMS ^5.0

  • For a SilverStripe 4.x compatible version of this module, please see the 2 branch.
  • For a SilverStripe 3.x compatible version of this module, please see the 1 branch, or 0.x release line.

Usage

Add and setup the extension on your DataObject

e.g. in config.yml:

MyDataObject:
  extensions:
    # adds a field called ArbitrarySettings
    - Arillo\ArbitrarySettings\SettingsExtension

  # define your settings
  settings:
    show_title:
      options:
        0: 'No'
        1: 'Yes'
      default: 0
      label: 'Show title as image caption?'
      description: 'Additional description goes here'
    image_alignment:
      options:
        'left': 'Left'
        'right': 'Right'
      default: 'left'
      label: 'Image alignment'

Note: All keys should be alphanumeric (including underscores, haven't tested other special characters yet) and should not contain whitespace.

To add the field in CMS you can use a helper method to show the field:

use Arillo\ArbitrarySettings\SettingsExtension;

public function getCMSFields()
{
    $fields = parent::getCMSFields();
    if ($settingsField = SettingsExtension::field_for($this))
    {
        $fields->addFieldToTab('Root.Main', $settingsField);
    }
    return $fields;
}

Values can be accessed like this:

$this->SettingByName('image_alignment') // returns 'left' or 'right'

in templates:

<div class="$SettingByName(image_alignment)">...</div>

SettingsField has functions available to manipulate the source of the field:

For including or excluding certain setting you can use:

// will show all settings but show_title
$settingsField->exclude(['show_title']);

// will show show_title setting only
$settingsField->include(['show_title']);

It is also possible to update the default value for a setting (for sure only if its present as an option):

$settingsField->updateDefaultForKey('show_title', 1);

Settings presets

It is possible to define a list of setting presets like this:

Arillo\ArbitrarySettings\SettingsExtension:
  presets:
    bg:
      options:
        transparent: 'Transparent'
        light: 'Light blue'
      default: transparent
      label: 'Background color'
    imgType:
      options:
        Default: 'Default image'
        Hero: 'Hero image'
      default: Default
      label: 'Image type'

With these presets defined it is possible to reference these keys in your DataObject's settings config, e.g.:

MyDataObject:
  extensions:
    - Arillo\ArbitrarySettings\SettingsExtension

  # define your settings
  settings:
    - bg
    - imgType

Translations

To translate the form field label used by SettingsExtension::field_for can be changed like this:

en:
  Arillo\ArbitrarySettings\SettingsExtension:
    Label: 'Options'

To translate options follow the following convention:

# for a config like this:
MyObject:
  settings:
    show_title:
      options:
        0: 'No'
        1: 'Yes'
      default: 0
      label: 'Show title as image caption?'
# the following translation keys can be used:
en:
  MyObject:
    setting_show_title_option_0: 'Nope'
    setting_show_title_option_1: 'Yep'
    setting_show_title_label: 'Use title as image caption'
