CodeIgniter将多维数组作为单独的行插入到数据库表中

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)

将post值保存到数组。 

  $ data2 = 数组（
'invoice_id'=＆gt;（$ id），
'order_id'=＆gt; $ this-＆gt; input-＆gt; post（'order_id'），
'sensactionitems_servicetype'=＆gt; $ this-  ＆gt;输入 - ＆gt;发布（'类型'），
'invoiceitems_quantity'=＆gt; $ this-＆gt;输入 - ＆gt;发布（'数量'），
'invoiceitems_unitprice'=＆gt; $ this-＆gt;  input-＆gt; post（'rate'），
'nickmentitems_notes'=＆gt; $ this-＆gt; input-＆gt; post（'description'）
）; 
 
 $ this-＆gt; db-＆gt  ; insert（'abc_invoiceitems'，$ data2）; 
 
print_r（$ data2）; 
   
 
 
数组结构。 
 
 
 数组
（
 [invoice_id] =＆gt; 21 
 [order_id] =＆gt; 1 
 [invoiceitems_servicetype] =＆gt;数组
（
 [0] =＆gt;订单
 [  1] =＆gt;杂项
 [2] =＆gt;订单
）
 
 [invoiceitems_quantity] =＆gt;数组
（
 [0] =＆gt; 5 
 [1] =＆gt; 64  
 [2] =＆gt; 88 
）
 
 [发票 items_unitprice] =＆gt; 数组
（
 [0] =＆gt; 5 
 [1] =＆gt; 6 
 [2] =＆gt; 8 
）
 
 [invoiceitems_notes] =＆gt; 数组
（
 [0] =＆gt; test Data1 
 [1] =＆gt; test Data2 
 [2] =＆gt; test Data3 
）
 
）
   
 
 
将数组值插入数据库表。 
 
 
  TABLE NAME --- abc_invoiceitems 
 + -----------  -  + ---------- + -------------------------- + ----------  ------------- + ------------------------ + -----------  --------- + 
 |  invoice_id |  order_id |  invoiceitems_servicetype |  invoiceitems_quantity |  invoiceitems_unitprice |  invoiceitems_notes | 
 + ------------ + ---------- + ---------------------  ----- + ----------------------- + --------------------  ---- + -------------------- + 
   
 
 
我收到以下错误并且 错误是： 
 
 
值以数组形式返回。 
 
 
 
 
 INSERT INTO  abc_invoiceitems （ invoice_id ， order_id ， invoiceitems_servicetype ， invoiceitems_quantity ， invoiceitems_unitprice ， invoiceitems_notes ）VALUES（'21'，'1'，数组，数组，数组，数组）

    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);
  }
