Question

我完成了这项工作并使用了我以前的项目。现在，我正在做一个新项目，并试图将我的代码复制并粘贴到文件上传中..它没有价值..我的问题是为什么我的文件上传没有得到价值？

注意：我已经在帮助器中声明了表单，并且文件夹已经存在。我的列名称是img_jumbotron，我的CI版本是3.3（最新）

控制器

public function addContent()
    {
      $config['upload_path'] = './uploaded/';   
      $config['max_size'] = '2048000';
      $config['overwrite'] = TRUE;          
      $config['allowed_types'] = '*';

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

      $this->load->library('form_validation');
      $this->form_validation->set_error_delimiters('<div class="alert alert-danger" role="alert">', '</div>');
      $example = $_POST['example'];
      $example = $this->input->post('userfile');
      print_r($example);die;
      if ($this->form_validation->run() == FALSE || !$this->upload->do_upload('userfile'))
      { 
          echo ('ksldfhsdj');
      } 
      else 
      {

          $content = array(
              'img_jumbotron' => $this->input->post('userfile'),
                'upload_data' => $this->upload->data()
              );

          print_r($content);die;
          $this->AdminModel->addContent($content); 
          redirect('Administrator/headContent');
      }

模型

public function addContent($content)
    {

        $content = array(
            'img_jumbotron' => $this->input->post('userfile'),
            'img_jumbotron' => $this->upload->data('file_name')
            );
        $this->db->insert('content', $content);
    }

Answer 1

您可以在浏览器上使用开发人员工具并检查NETWORK（我猜是否为chrome）选项卡，并检查您的应用程序是否正在发送文件。

还有：

action="<?=base_url().'Administrator/addContent/'?>"

我认为您应该删除此“<?=”上的等号。
