Inserting multiple form fields with same name

Thanks for fast reply skunkbad.

I've already tried that approach, and so far seems the best.
The only problem is that I'm using Jamie Rumbelow's CRUD model https://github.com/jamierumbelow/codeigniter-base-model which is implementing the following validation pattern: http://ellislab.com/codeigniter/user-gui...lesasarray.
And since I want to have dynamic number of room types, e.g. 5 sets for free user, 10 sets of room types for paid user, the validation rules should be defined dynamically as well.

For example, if the user has opened and filled 3 sets of room types, the validation rules for first set in Rumbelow's MY_Model should be:

Code:

protected $validate = array(
   array(
    'field' => 'room_types_1',
    'label' => 'room_types',
    'rules' => 'trim|required|xss_clean|min_lenght[3]'  
   ),
   array(
    'field' => 'room_types_mk_1',
    'label' => 'room_types',
    'rules' => 'trim|required|xss_clean|min_lenght[3]'
   ),
   array(
    'field' => 'max_occupancy_1',
    'label' => 'room_types',
    'rules' =>'trim|required|xss_clean|min_lenght[1]|max_length[2]'  
   ),
   array(
    'field' => 'extra_bedding_1',
    'label' => 'room_types',
    'rules' => 'trim|xss_clean|min_lenght[1]|max_length[2]'
   )  
);

But real problem occurs when the user, for example, has opened 5 sets of room types but filled only 3.
Then, instead of inserting only 3 sets, there will be validation error on other 2 since they are empty.

I guess I should switch to normal AC (without using MY_Model CRUD) for this form to avoid this problem and use you solution.
