I'm trying to figure out how to add an option on my CMS editor page, sidebar content. So far I've done this:

function getCMSFields() 
   { 
      $fields = parent::getCMSFields(); 
      $fields->addFieldToTab(
	     "Root.Content.Sidebar",
		 new HTMLEditorField('SideContent','Sidebar content')); 
		 
	  $fields->addFieldToTab(
	     "Root.Content.Sidebar",
		  new OptionsetField(
		    'ShowSocial',
		    $title = 'Show social widgets on this page',
		    $source = array(
			  '1' => 'show','2' => 'hide'),
			'1'
		    ));			  
      return $fields;
   }

In my page controller, which shows the controls but doesn't save their state when I click save. What am I missing?

You probably need to declare:

static $db = array(); or a $has_one or $has_many relationship titled 'ShowSocial'

Else you are giving the program the interface to do what you want, but you're not giving it anywhere to be saved.
