How to get values from checked checkboxes

Answer 1

All data is stored in $this->data (readonly) or $this->request->data (can be modified) after a form submit. Wrap the aforementioned $this->data in a debug() call to see the structure of the returned data. It will probably look roughly like the following:

  array(
    'ModelName' => array(
      'name' => 'value',
      'name' => 'value'
    )
  )
