The label wrapping logic is hardcoded in the view helper, specifically
Zend_View_Helper_FormRadio. Overriding that logic would involve a lot of
code duplication. If you're fine with that:
- create a file named MyMultiCheckbox.php in your application/views/helpers
directory
class Zend_View_Helper_MyMultiCheckbox extends
Zend_View_Helper_FormMultiCheckbox
{
public function myMultiCheckbox($name, $value = null, $attribs = null,
$options = null, $listsep = "<br />")
{
// stuff
}
}
- open the file Zend/View/Helper/FormRadio.php, copy the contents of the
formRadio() method to the method above and modify it to fit your needs. You
might also want to move the break-every-3-elements behavior here.
- tell the element to use your helper
$foo = new Zend_Form_Element_MultiCheckbox('foo', array(
'multiOptions' => $opts,
'decorators' => $decorators,
'helper' => 'MyMultiCheckbox'
));
