If this is a HABTM relationship, which it would have to be to allow
many contents to be related to many categories, then you have your
field named wrong.
You essentially have a belongsTo field there where one row can only
have one relation to Category via Content.category_id, what you need
is a field like:
$this->Form->input('categories', array('type'=>'select',
'multiple'=>'checkbox', 'options'=>$categories));
This will give you a data[Category][Category] type array.
