推荐答案

希望这对您有帮助：

使用 $ config 中的 upload_path 的 FCPATH >

您的最新新闻方法应如下所示：

Your Latest_news method should be like this :

public function Latest_news()
{  
    $this->form_validation->set_rules('first_content', 'First content', 'required');
    $this->form_validation->set_rules('second_content', 'Second content', 'required');

    if ($this->form_validation->run())
    {
        $config['upload_path']   = FCPATH.'uploads/'; 
        $config['allowed_types'] = 'gif|jpg|png'; 
        $this->load->library('upload', $config);

        if ( $this->upload->do_upload('filename') )
        {
            print_r($this->upload->data());die; 
            $data['first_content'] = $this->input->post('first_content');
            $data['second_content'] = $this->input->post('second_content');
            $data['filename'] = $this->upload->data('file_name');  

            //Transfering data to Model
            $this->Contact_model->latest_news($data);
            //Redirecting to success page
            redirect(site_url('Home/Latest_news'));     
        }
        else
        {
            $error = array('error' => $this->upload->display_errors());
            print_r($error);die;
        }
    }
    else
    {
          $this->load->view('Latest_news'); 

    }
} 

使用 form_open_multipart（）而不是 form_open（）

您的表单应为像这样：

 <?php echo form_open_multipart('Home/Latest_news'); ?>
        <div style="padding-top:10%; padding-left:30%">
            <div>
                <textarea name="first_content" rows="4" cols="50"></textarea>
                <span><?php echo form_error("first_content");?></span>
            </div><br>
            <div>
                <textarea name="second_content" rows="4" cols="50"></textarea>
                <span><?php echo form_error("second_content");?></span>
            </div><br>
            <div>
                <input type="file" name="filename">
                <span><?php echo form_error("filename");?></span>
            </div><br>
          <button type="submit" class="btn btn-default">Submit</button>
        </div>
    </form>
