How to add Blocks to Stacks with code

Permalink April 11, 2012 at 7:37 AM

My purpose is to add a block - from blocktype survey and add it to a non-global stack.
What I have so far:

Loader::model('attribute/categories/collection');
   $args['question']='Just a question';
   $options=array(0=>'Yes',1=>'No');
   $args['pollOption']=$options;
   $args['requiresRegistration']='1';
 $stack = Stack::getByName('Glasovanje');
$cb = BlockType::getByHandle('survey');
$stack->addBlock($cb, "Global", $args);  //Don't know what to write instead of global..
