Maintainer Contacts

• Marcus Nyeholt (marcus@symbiote.com.au)

Requirements

• SilverStripe 3+
• The SilverStripe Orderable module.

Getting started

• Add the extension to your data class, eg Object::add_extension('Page', 'MetadataExtension');
• Navigate to the Metadata section of the CMS (/admin/metadata)
• Create a new Metadata Schema. Note that the 'Title' is what is used to refer to the item from templates, so try and limit this to a-z0-9_-. characters - eg test_schema
• Add a few metadata fields - some usual ones are
  • Title (title)
  • Keywords (keywords)
  • Description (description)
• Set the 'Default' value for each of these to $Title. Leave the 'cascade' setting blank for now, as you're providing a default already
• Navigate to a top level page and on its Metadata tab, select the schema you just created; click save
• Enter metadata values
• In your Page.ss template, add the following to output all metadata fields
  • $MetadataMetaTags
• To output just the values for a particular applied schema, use
  • $MetadataMetaTags(SchemaName)
• To access raw metadata values directly, use
  • $Metadata(SchemaName,FieldName) eg $Metadata(test_schema,keywords)
