Question

我试图在CodeIgniter（PHP）中创建一个函数，以便用户可以将图像添加到我的数据库中，但是当我尝试上传图像时收到错误。

我正在使用phpMyAdmin

数据库名称：kadokado

表名：产品

表格行名称我想将这些图像放到：product_foto

图片文件夹：上传

我的控制器文件（Product.php）：

    class Product extends CI_Controller { 


    var $data = array();

       public function __construct()
 {
  parent::__construct();
 }

}

     public function index()
 {
  $config = array (
   'upload_path' => 'upload/',
   'allowed_types' => 'jpg|jpeg|png|bmp',
   'max_size' => 0,
   'filename' => url_title($this->input->post('file'))

   );
   $this->load->library('upload', $config);

   if ($this->upload->do_upload('file')) {
    $this->db->insert('products', array(
        'product_foto' => $this->upload->product_foto
     ));
     $this->session->set_flashdata('msg', 'Success');
   }

  $this->load->view('product_form', $this->data);
 }

}

这是我的视图文件（product_form.php）：

<?php
echo $this->session->flashdata('msg');
echo form_open_multipart();
echo form_upload('file');
echo form_submit('upload', 'Upload');
echo form_close();
?>

这些是我得到的错误：`

Answer 1

更改

if ($this->upload->do_upload('file')) {
    $this->db->insert('products', array(
        'product_foto' => $this->upload->product_foto
     ));
     $this->session->set_flashdata('msg', 'Success');
   }

到

 if ($this->upload->do_upload('file')) {
    $this->db->insert('products', array(
        'product_foto' => $this->upload->data['file_name']
     ));
     $this->session->set_flashdata('msg', 'Success');
   }

$config['upload_path']      = 'uploads/size/';        
                $config['allowed_types']    = 'gif|jpg|png|jpeg';
                $config['max_size']         = '1024*20';
                $config['encrypt_name']     = true;
                $this->load->library('upload', $config);
                $uploaded   = $this->upload->do_upload('photo');   if($uploaded){                                                          $image_productimage1         = $this->upload->data();
$insert_data['size_image']  = $image_productimage1['file_name'];        
// insert data into the database                                                                       }
