laravel many to many delete and update

I have many to many relationship .

in the blade code i sent many items with actionID[]

and then i insert them like this:

$detailsAttribute->actions()->sync(Input::get('action_id'));

now I want to update that model.

i used this same statement

$detailsAttribute->actions()->sync(Input::get('action_id'));

it creates the new actions but didn't remove the older ones. In other words, when I edit the model $detailsAttribute, I delete the older actions and I select many new ones.

my question is how to update the model considering removing the non selected actions?

sync() method will remove all those items from pivot table if they are not present in your Input::get('action_id') array. If they are not removed that means you are also passing old data in the new array. var_dump your Input and see what kind of array you are getting.
