如何在Codeigniter中插入动态数据？

I just want to insert dynamic generated input field data into database . My db table having three fields , id(Auto Increment), product_name and rate . I'm trying to insert bulk data into database using dynamically generated input fields where I can add/remove input fields manually. I created the input fields as

<input class="form-control" placeholder="Product Name" name="prodname[]" type="text">
<input class="form-control" placeholder="Product Rate" name="prodrate[]" type="text">

这是我下面的控制器

function Act_AddProducts() {
        if ( $this->input->post( 'prodname' )&&$this->input->post( 'prodrate' )) {
            foreach ( $this->input->post( 'prodname' ) as $key => $value ) {

                $this->ProductModel->add_products( $value );
            }

        }

模型函数如下

function add_products($val)
  {
      if($this->db->insert('tbl_product_master', array('product_name' => $val)))
      {
        return true;
      }
      else
      {
        return false;
      }
  }

现在该值正在插入到数据库中，但一次插入一个。所以请帮我找出代码问题。我也不太明白如何插入比例[]值到同​​一个插入查询中。

希望对你有帮助

你的控制器Act_AddProducts应该是这样的：

function Act_AddProducts() 
{
   $prodnames = $this->input->post( 'prodname' );
   $prodrates = $this->input->post( 'rate' );
    if ( ! empty($prodnames) && ! empty($prodrates) ) 
    {
        foreach ($prodnames as $key => $value ) 
        {
            $data['product_name'] = $value;
            /* make sure product_rate columns is correct i just guess it*/
            $data['product_rate'] = $prodrates[$key];
            $this->ProductModel->add_products($data);
        }

    } 
}

你的模型add_products应该是这样的：

function add_products($data)
{
   if ( ! empty($data))
   {
      $this->db->insert('tbl_product_master', $data);
   }
}
