在codeIgniter中将数据数组插入数据库

Question

我正在尝试将使用jquery创建的动态文本字段中的数据插入数据库中。但是，只有第一行数据存储在数据库中，而其他行则没有。我无法找到原因，因为我希望循环可以处理数组中的所有数据。我不知道我在做什么错。

这是我的观点

<tbody id="item_body">
    <tr id="item_row">
      <th>1</th>
      <td>
      <select class="form-control" name="item_name[]" id="item_name" style=" width:150px;">
       <option value="none" selected="" disabled="">Select Item</option>
       <?php foreach ($items as $item):?>
       <option value="<?php echo $item['id'];?>"><?php echo $item['item_name']; ?> </option>
       <?php endforeach;?>
      </select>
      </td>
      <td><input type="text" name="price_p_u[]"  id="price_p_u" class="form-control"></td>
      <td><input type="text" name="qty_unit[]" id="qty_unit" class="form-control"></td>
      <td>
      <select name="unit-type[]" id="unit-type" class="form-control" style=" width:90px;">
      <option value="none" selected="" disabled="">Choose</option>
      <option value="Unit">Unit</option>
      <option value="Sub-Unit">Sub-Unit</option>
      </select>
      </td>
      <td><input type="text" name="qty[]" id="qty" class="form-control"></td>
      <td><input type="text" name="total_price[]" id="total_price" class="form-control"></td>
      <td><input type="button" name="" id="add_fields" class="btn btn-success" value="+"></td>
    </tr>
   </tbody>
   <tbody id="total_part">
     <tr>
     <td></td>
     <td></td>
     <td></td>
     <td></td>
     <td></td>
     <td>Total</td>
     <td id="grand_total">GH0.00</td>   
     </tr>
   </tbody>

Answer 1

希望这对您有帮助：

在return

之前从for循环中删除$this->db->insert('sales',$data);

您的new_sale()方法应如下所示：

public function new_sale()
{
   $sales_date=$this->input->post('sales_date');
   $name_customer=$this->input->post('name_customer');
   $invoice_no=$this->input->post('invoice_no');
   $item_id=$this->input->post('item_name');
   $unit_type=$this->input->post('unit-type');
   $qty=$this->input->post('qty');
   $r_total_price=$this->input->post('total_price');

   for($i=0; $i<count($r_total_price); $i++)
   {
      $data = array('sales_date'=>$sales_date,
                 'name_customer'=>$name_customer,
                 'invoice_no'=>$invoice_no,
                 'item_id'=>$item_id[$i],
                 'unit-type'=>$unit_type[$i],
                 'qty'=>$qty[$i],
                 'r_total_price'=>$r_total_price[$i]
            );
    $this->db->insert('sales',$data);
    }
}
