Php 使用codeigniter将图像压缩并上载到表中，而不将图像存储在上载文件夹中

使用codeigniter将图像压缩并上载到数据库表中，而不将图像存储在上载文件夹中。我没有收到任何错误，但图像没有插入到表中。有错吗？请推荐我

控制器

public function buyer_profile_image() {

        $file_type = $_FILES['image']['type'];

        $allowed = array("image/jpeg", "image/gif", "image/png");
        if (!in_array($file_type, $allowed)) {
            $this->load->view('buyerprofile'); 
        } else {
            $source_img = $_FILES['image']['tmp_name'];


            $destination_img = 'destination .jpg';


            $d = $this->compress($source_img, $destination_img, 50);


            $image = addslashes($d);
            $image = file_get_contents($image);
            $image = base64_encode($image);


            if ($image == "") {
                $_SESSION["errmsg"] = "please select image to post";
                $this->load->view('buyerprofile'); 
            } else {

                $data = array(

                    'profile_image' => $image,

                              );

                $this->Profile_model->Product_insert($data);

                 $this->load->view('buyerprofile'); 

            }
        }
    }

型号

public  function Product_insert($data){
$this->db->insert('siddu',$data);
