CodeIgniter将多维数组作为单独的行插入到数据库表中

已采纳

saving post value to an array.

$data2 = array(
  'invoice_id' =>($id),
  'order_id' => $this->input->post('order_id'),
  'invoiceitems_servicetype' =>$this->input->post('type'),
  'invoiceitems_quantity' => $this->input->post('quantity'),
  'invoiceitems_unitprice' => $this->input->post('rate'),
  'invoiceitems_notes' => $this->input->post('description')
      );

 $this->db->insert('abc_invoiceitems', $data2);

print_r($data2);

Array Structure.

Array
(
    [invoice_id] => 21
    [order_id] => 1
    [invoiceitems_servicetype] => Array
        (
            [0] => Order
            [1] => Miscellaneous
            [2] => Order
        )

    [invoiceitems_quantity] => Array
        (
            [0] => 5
            [1] => 64
            [2] => 88
        )

    [invoiceitems_unitprice] => Array
        (
            [0] =>  5
            [1] =>  6
            [2] =>  8
        )

    [invoiceitems_notes] => Array
        (
            [0] => test Data1
            [1] => test Data2
            [2] => test Data3
        )

)

Insert array values to database table.

TABLE NAME --- abc_invoiceitems 
 +------------+----------+--------------------------+-----------------------+------------------------+--------------------+
 | invoice_id | order_id | invoiceitems_servicetype | invoiceitems_quantity | invoiceitems_unitprice | invoiceitems_notes |
 +------------+----------+--------------------------+-----------------------+------------------------+--------------------+

I got this following error and the error is :

the values are returning as array.

INSERT INTO abc_invoiceitems (invoice_id, order_id, invoiceitems_servicetype, invoiceitems_quantity, invoiceitems_unitprice, invoiceitems_notes) VALUES ('21', '1', Array, Array, Array, Array)

    Fetch post values:

    $temp =count($this->input->post('type'));//counting number of row's
    $type= $this->input->post('type');
    $quantity = $this->input->post('quantity');
    $rate = $this->input->post('rate');
    $description = $this->input->post('description');
    

    Loop through Key values:

    for($i=0; $i<$temp;$i++){
      $data2 = array(
      'invoice_id' =>($id),
      'order_id' => $this->input->post('order_id'),
      'invoiceitems_servicetype' =>$type[$i],
      'invoiceitems_quantity' => $quantity[$i],
      'invoiceitems_unitprice' => $rate[$i],
      'invoiceitems_notes' => $description[$i]
          );
       $this->db->insert('abc_invoiceitems', $data2);
      }

    How about turning the arrays into serialized strings?

    $data2 = array(
        'invoice_id' =>($id),
        'order_id' => $this->input->post('order_id'),
        'invoiceitems_servicetype' => serialize($this->input->post('type')),
        'invoiceitems_quantity' => serialize($this->input->post('quantity')),
        'invoiceitems_unitprice' => serialize($this->input->post('rate')),
        'invoiceitems_notes' => serialize($this->input->post('description'))
    );
    
    $this->db->insert('abc_invoiceitems', $data2);
    

    When you want to pull the data back out of the database, you can unserialize the strings.
