# SiteConfig
## Introduction
The SiteConfig panel was introduced in 2.4 for providing a generic interface for managing site wide settings or
functionality which is used throughout the site. Out of the box it provides 2 fields 'Site Name' and 'Site Tagline'.
## Accessing SiteConfig Options
You can access SiteConfig options from any SS template by using the function $SiteConfig.FieldName
:::ss
$SiteConfig.Title
$SiteConfig.Tagline
// or
<% control SiteConfig %>
$Title $AnotherField
<% end_control %>
Or if you want to access variables in the PHP you can do
:::php
$config = SiteConfig::current_site_config();
$config->Title
## Extending SiteConfig
To extend the options available in the panel you can define your own fields via an Extension.
Create a mysite/code/CustomSiteConfig.php file.
:::php
<?php
class CustomSiteConfig extends DataObjectDecorator {
function extraStatics() {
return array(
'db' => array(
'FooterContent' => 'HTMLText'
)
);
}
public function updateCMSFields(FieldSet $fields) {
$fields->addFieldToTab("Root.Main", new HTMLEditorField("FooterContent", "Footer Content"));
}
}
Then add a link to your extension in the _config.php file like below.
Object::add_extension('SiteConfig', 'CustomSiteConfig');
This tells SilverStripe to add the CustomSiteConfig extension to the SiteConfig class.
After adding those two pieces of code, rebuild your database by visiting http://yoursite.com/dev/build and then reload
the admin interface. You may need to reload it with a ?flush=1 on the end.
You can define as many extensions for SiteConfig as you need. For example if you are developing a module you can define
your own global settings for the dashboard.
