Answer 1

The problem is that you're manually building the checkbox options, and adding a dot in the field name.

The way to do this is to do this the Cake way:

$options = array();

foreach($menu_page_1 as $menu_pages) {
    $options[$menu_pages['MenuPage']['id']] = $menu_pages['MenuPage']['name'];
}
echo $this->Form->select('top_links', $options, array(
    'multiple' => 'checkbox'
));
