Adding social media meta tags to DataObjects

By default, this module will only add social media meta tags to SiteTree objects.

To add social media meta tags to DataObjects:

• in /mysite/_config.php, add the extension to each DataObject class you wish.
  • e.g. Recipe::add_extension('SocialMetaTagsExtension');
• in /mysite/_config/config.yml, set options for titles, descriptions, and images (if desired) for your class.
  • for an example, see the above example config.yml.
• in your DataObject's class, add new fields in getCMSFields():

  public function getCMSFields() {
      $fields = parent::getCMSFields();
      
      ...
      
      $fields->addFieldToTab('Root.Main', new TextareaField("SocialMetaDescription"));
      $fields->addFieldToTab('Root.Main', new UploadField("SocialMetaImage"));
      
      return $fields;
  }
