title: SiteConfig summary: Content author configuration through the SiteConfig module. # SiteConfig The `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. ```ss $SiteConfig.Title $SiteConfig.Tagline <% with $SiteConfig %> $Title $AnotherField <% end_with %> ``` To access variables in the PHP: ```php use Silverstripe\SiteConfig\SiteConfig; $config = SiteConfig::current_site_config(); echo $config->Title; // returns "Website Name" ``` ## Extending SiteConfig To extend the options available in the panel, define your own fields via a [DataExtension](api:SilverStripe\ORM\DataExtension). **app/code/extensions/CustomSiteConfig.php** ```php use SilverStripe\Forms\FieldList; use SilverStripe\Forms\HTMLEditor\HTMLEditorField; use SilverStripe\ORM\DataExtension; class CustomSiteConfig extends DataExtension { private static $db = [ 'FooterContent' => 'HTMLText' ]; public function updateCMSFields(FieldList $fields) { $fields->addFieldToTab("Root.Main", new HTMLEditorField("FooterContent", "Footer Content") ); } } ``` Then activate the extension. **app/_config/app.yml** ```yml Silverstripe\SiteConfig\SiteConfig: extensions: - CustomSiteConfig ```
