Insert Multiple Row Data Usibg Checkbox

hi to all, i have a problem inserting multiple row data using checkbox to my database.

example.

i have checkboxlist that already selected

room1

room2

room3

i want to insert to my database in a row.

example i have table rooms.

id room

1 room1

2 room2

3 room3

and so on depends on what checkbox they are selected…

Can you tell me what exactly problems you have faced. supposed if not inserted two or more than you need to use like this -

$your_model->isNewRecord = true;

$your_model->save(false);
