Question

我拥有arrays中表中的所有数据。其中updated existing data和一些added new data。该数据是从 CSV 导入的，并存储在array中。

问题是：

如何在Codeigniter中使用“ ON DUPLICATE KEY UPDATE”通过单个查询插入和更新现有数据？

像这样的桌子。

id(auto incre)   invoice_code    item_code   item_rate

1                INPO311018-1    pip640up    62
2                INPO311019-43   plxliupp    43
3                INPO311012-05   al6408f     24

在同一时刻插入并更新后的表将如下所示。

id(auto incre)   invoice_code    item_code   item_rate

1                INPO311018-1    pip640up    59.99
2                INPO311019-43   plxliupp    40
3                INPO311012-05   al6408f     25.99
4                INPO011019-3   Ndry_milk    1.4
5                INPO021012-05   al894_ad     99

控制器

  function import_csv()
          {
            $this->load->library('csvimport');  //Load Library

            $file_data=$this->csvimport->get_array($_FILES["csv_file"]["tmp_name"]);
            foreach ($file_data as $row) {

              $data[]=array(
                'id'=>$row['id'],
                'invoice_code'=>$row['invoice Code'],
                'item_code'=>$row['item Code'],
                'item_rate'=>$row['item Code'],

              );

            }

            $this->load->model('invoice_model');
            $this->invoice_model->insert_data($data);

          }

型号

  function insert_data($data)          //Add & Update table with "CSV"

        {
            $this->db->insert_batch('po_invoice',$data);
        }

**非常感谢，谁能解决这个问题:) **

这太疯狂了..也许吧..我没有正确地使用它...但是尝试一下...

<script>
gtag('event', 'purchase', {
  "send_to": "AW-XXXXXXXX/<Conversion Label>",
  "transaction_id": "24.031608523954162",
  "affiliation": "Google online store",
  "value": 23.07,
  "currency": "USD",
  "tax": 1.24,
  "shipping": 0,
  "items": [
    {
      "id": "P12345",
      "name": "Android Warhol T-Shirt",
      "list_name": "Search Results",
      "brand": "Google",
      "category": "Apparel/T-Shirts",
      "variant": "Black",
      "list_position": 1,
      "quantity": 2,
      "price": '2.0'
    },
    {
      "id": "P67890",
      "name": "Flame challenge TShirt",
      "list_name": "Search Results",
      "brand": "MyBrand",
      "category": "Apparel/T-Shirts",
      "variant": "Red",
      "list_position": 2,
      "quantity": 1,
      "price": '3.0'
    }
  ]
});
</script>

处于模式...

function import_csv()
          {
            $this->load->model('invoice_model'); /// load it at beginning 
            $this->load->library('csvimport');  //Load Library

            $file_data=$this->csvimport->get_array($_FILES["csv_file"]["tmp_name"]);
            foreach ($file_data as $row) {

              $data = array(
                'id'=>$row['id'],
                'invoice_code'=>$row['invoice Code'],
                'item_code'=>$row['item Code'],
                'item_rate'=>$row['item Code'],
              );
           // in order to insert or update ... you cannot use insert batch ....  
           // pass it one by one 
             $this->invoice_model->insert_update_data($data);

            }


           //  $this->invoice_model->insert_data($data);

          }

如何在Codeigniter中通过一个查询插入和更新现有数组数据？
