Version 5 supported


The silverstripe/siteconfig module provides a generic interface for managing site-wide settings or functionality which is used throughout the site. Out of the box, this includes setting the site name and site-wide access.

Accessing variables

SiteConfig options can be accessed from any template by using the $SiteConfig variable.


<% with $SiteConfig %>
    $Title $AnotherField
<% end_with %>

To access variables in the PHP:

use Silverstripe\SiteConfig\SiteConfig;

$config = SiteConfig::current_site_config();

// prints "Website Name"
echo $config->Title;

Extending SiteConfig

To extend the options available in the panel, define your own fields via an Extension.

// app/src/Extension/CustomSiteConfig.php
namespace App\Extension;

use SilverStripe\Core\Extension;
use SilverStripe\Forms\FieldList;
use SilverStripe\Forms\HTMLEditor\HTMLEditorField;

class CustomSiteConfig extends Extension
    private static $db = [
        'FooterContent' => 'HTMLText',

    public function updateCMSFields(FieldList $fields)
        $fields->addFieldToTab('Root.Main', HTMLEditorField::create('FooterContent', 'Footer Content'));

Then apply the extension.

# app/_config/extensions.yml
    - App\Extension\CustomSiteConfig

After adding the class and the YAML change, make sure to rebuild your database by visiting You may also need to reload the screen with a ?flush=1 i.e.

You can define as many extensions for SiteConfig as you need. For example, if you're developing a module and want to provide the users a place to configure site-wide settings then the SiteConfig panel is the place to go it.
