I want to insert to database multiple data codeigniter

I want to insert to database multiple data codeigniter

This is my VIEW:
for ($i=1; $i < $loop_count ; $i++) {
echo $this->formbuilder->text( 'dates[]', 'Set Date '.$i);
}
This is my model:
function add_pm($data) {
$this->db->insert($this->table, $data);
$this->session->set_flashdata("message", "Contract record
successfully created.");
}
And now my question is what will i put in controller and how can i insert
it in database in loop? I wish someone will help me!
