Send an object with value of your data(as JSON) to your Controller. e.g (with JQuery):
$.post('your_action_url', {sendData: JSON.stringify(yourData)}, function(res) {
console.log(res);
}, "json");
Then in your controller, you can get the Data with this CI method:
$data = json_decode($this->input->post('sendData'));
and if the $data is an Array of objects and you want to filter the $data, you can loop the $data then call the save method in your model
$this->db->trans_begin();
foreach($data as $row) {
$filter_data = array(
"id_buku" => $row->id_buku,
"jumlah" => $row->jumlah,
"subtotal" => $row->subtotal
);
//Call the save method
$this->your_model_alias->save_as_new($filter_data);
}
if ($this->db->trans_status() === FALSE) {
$this->db->trans_rollback();
echo json_encode("Failed to Save Data");
} else {
$this->db->trans_commit();
echo json_encode("Success!");
}
Consider to use a transaction to store a lot of data at once. This is necessary to avoid things that are not desirable.
your Model's save method should be like this :
public function save_as_new($data) {
$this->db->insert('your_table_name', $data);
}
