SilverStripe Multisites

Overview

Allows for multiple websites to be managed through a single site tree.

This is an alternative module to the Subsites module; it avoids any session tracking of the 'current' website, and doesn't perform any query modification at runtime to change the 'site' context of queries you execute

Compatible with SilverStripe 4.0.x

• Please see 4.0.x for 3.5 compatibility
• Please see the 1.2.x version for 3.1 compatibility

Upgrading to SS4

The following important changes have happened

• Themes must now be explicitly configured in your project config. Set Site.available_themes in yml config. This must be a map of themename: Label
• Site specific Assets folders are not currently supported due to the fundamental change to asset management. This will be reviewed over time

Requirements

• SilverStripe 4.*
• MultivalueField

Installation

• Add the module and the multivaluefield module
• Run dev/build

Setting up sites (and additional sites)

• In the CMS go to the Pages section and click on the Website
• Enter in the full path to the site in the 'Host' field, without the http:// lead - eg mysitedomain.com or localhost/sub/folder for a development site
• Hit save
• To add a new site, click the Pages section; you should have an 'Add site' button
• Enter details about the new site, the Host field being the most important

Configuration

Site:
  available_themes:
    name: Label

To support cascading themes, provide a comma-separated list of themes for 'name' in configuration.

Assets management

NOTE: This is currently NOT working in SS4 due to the change to the asset management layer. Once clearer, this will be re-enabled.

You can optionally manage each site's assets in it's own subfolder of the root assets/ directory. Add the following extensions in your mysite/config.yml file and run ?flush=1. When editing a Site in the CMS, you now have the option to select a subfolder of assets/ to contain all assets for that site. This folder will be automatically created upon a) saving the site or b) visiting a page in the cms that has an upload field.

FileField:
  extensions:
    - MultisitesFileFieldExtension

HtmlEditorField_Toolbar:
  extensions:
    - MultisitesHtmlEditorField_ToolbarExtension

Files uploaded through the HTMLEditor will now be uploaded into assets/yoursite/Uploads. If you have custom upload fields in the cms however, you will need to add the following configuration to them explicitly.

$fields->fieldByName('Root.Main.Image')->setFolderName('images/page-images')->useMultisitesFolder();

The above call to useMultisitesFolder() will change the folder name from ' images/page-images' to 'currentsitesubfolder/images/page-images'

Known issues

When linking to a page that belongs to a different site, SiteTree::Link() will return a bad link as it prepends the base URL. Currently the best way to work around this is to implement the following in your Page.php (model class).

/**
 * Overrides SiteTree->Link. Adds a check for cases where we are linking to a
   page on a
 * different site in this multisites instance.
 * @return String
 **/
public function Link($action = null) {
	if($this->SiteID && $this->SiteID == Multisites::inst()->getCurrentSiteId()) {
		return parent::Link($action);
	} else {
		return $this->RelativeLink($action);
	}
}
