class Test extends Page {
static $db = array(
static $has_one = array(

   function getCMSFields() {
   $fields = parent::getCMSFields();

      new CheckboxSetField(
    $name = "topics",
    $title = "I am interested in the following topics",
    $source = array(
    "1" => "Technology",
    "2" => "Gardening",
    "3" => "Cooking",
    "4" => "Sports"
    $value = "1"
return $fields;


I realize this is a very basic question, but I am new to silverstripe and I am stumped.

How do I declare the variable "topics", as it stands, the checkboxes appear fine in the admin part, but I can't save them (they always revert back to the default value) nor display results.

Hi tonito,
Try adding a database field to save the selection into. Your $db array becomes:

static $db = array(
'topics' => 'Varchar'

Because your checkboxsetfield also has the name 'topics' , the data will be saved into the 'topics' database field for each test page.

Chances are you'll be wanting to do something more advanced than that. You should learn about the SilverStripe [url=]datamodel[/url] , perhaps also go through the [url=]tutorials[/url].
