将多个图像插入数据库时​​，在连接到图像表的主表中添加了多行

Question

我正在尝试在Codeigniter中上传多个图像。对于特定产品，我想在使用“ lastid”时将上载的图像添加到另一个表中，称为“ image” ....，以便在图像中获得pid（来自表product_multi的产品ID），在product_multi表中插入多个行。 ..数量行是根据我上传的图片数量而定。
有人帮助我解决了这个问题。如果我不使用传递lastid的变量，它可以正常工作/ ...但是我想在图像表中使用pid：（

这就是我如何获得数据

这是我的模特

#include <iostream>
#include <sstream>


int main(void)
{
    int arr[] = { 192,168,1,0 };
    std::stringstream ss;
    ss << arr[0] << "." << arr[1] << "." << arr[2] << "." << arr[3];


    std::cout << ss.str() << std::endl;
}

控制器代码：：

<?php


class ProductmModel extends CI_Model
{

  var $PRODUCTNAME='';
  var $DESCRIPTION='';
  var $CATEGORY='';
  var $SUBCAT='';
  var $IMAGE='';




public function addproductm()
{
$this->load->database();
$data = array(
"p_name" => $this->PRODUCTNAME,
"p_des" => $this->DESCRIPTION,
"cat" => $this->CATEGORY,
"subcat" => $this->SUBCAT

);
$this->db->insert('product_multi', $data);
$lastid=$this->db->insert_id();
echo "$lastid";
return $lastid;

}


public function addimage()
{
$last=$this->addproductm();
$this->load->database();

$data = array(
"pid" =>$last,
"images" => $this->IMAGE
);
$this->db->insert('image', $data);
}


}

这是您所说的编辑后的代码...在单个函数中都插入

       $this->ProductmModel->addproductm($product_array, $fileInfos);

     public function addproductm($product_array, $fileInfos){
