Checkboxes only return a value if checked. The solution is to make your
update query update all fields with the default value set to unchecked.
The unchecked fields will automatically be unchecked because the POSTed
value will not exist.
Of course you will have to explicitly name your check boxes something
like <input name='menu_show_attribute[".$row['menu_id']."]'
type='checkbox'
class='checkbox')
And of course you won't be able to loop through the array
$_POST['menu_show_attribute'] because the unchecked values will not
show. However you could include a hidden field
<input name='hidden_menu_id[".$row['menu_id']."]' type='hidden'>
Then update your db by looping through $_POST['hidden_menu_id']
