如何使用codeigniter在mysql中保存多行

Question

I have a form for a hotel site, where I want to update its services, and the client wants to update multiple services at a time. However I'm lost as how to save it in the database with the model.

I already built my controller, it looks something like this:

$items = array(
        array(
                'id'           => $this->input->post('id1', true),
                'hotel_id'     => $hotel_id,
                'des_servicio' => $this->input->post('des_servicio1', true),
                'est_activo'   => $this->input->post('est_activo1', true)
        ),
        array(
                'id'           => $this->input->post('id2', true),
                'hotel_id'     => $hotel_id,
                'des_servicio' => $this->input->post('des_servicio2', true),
                'est_activo'   => $this->input->post('est_activo2', true)
        ),
        array(
                'id'           => $this->input->post('id3', true),
                'hotel_id'     => $hotel_id,
                'des_servicio' => $this->input->post('des_servicio3', true),
                'est_activo'   => $this->input->post('est_activo3', true)
        )
);

$this->hotel_model->save_multiple($items);

[UPDATE]

this is how my new model looks like:

function save_multiple($items = array())
{
    $this->db->insert_batch($this->__tabla, $items);
    return $this->db->affected_rows();
}

My issue is that now it creates 10 rows (my original form has 10 fields) even if I only populate 3 fields. So in my database 3 services get stored, and also 7 blank rows. How can change this?

Answer 1

foreach $items //I get an error here
    as $item 

should be

foreach ( $items as $item ) 

Answer 2

Remember that input->post() returns false if the value is not set. So check to see if the value is set be for putting it in the array. Then when the model receives it. It saves them all. Or the other option is to create a new array in the model from the array that is passed in and then pass the new array to the insert_batch() function.

$items = array();

$id = $this->input->post('id1', true);
if( $id != false ) {
    $items[] = array(
        'id'           => $id, true),
        'hotel_id'     => $hotel_id,
        'des_servicio' => $this->input->post('des_servicio1', true),
        'est_activo'   => $this->input->post('est_activo1', true)
    );
}

$id = $this->input->post('id2', true);
if( $id != false ) {
    $items[] = array(
        'id'           => $id, true),
        'hotel_id'     => $hotel_id,
        'des_servicio' => $this->input->post('des_servicio2', true),
        'est_activo'   => $this->input->post('est_activo2', true)
    );
}
