这是我的codeigniter控制器功能。使用此功能，我可以将数据添加到数据库。但是，我无法上传图片。在upload_files中启用了php.ini即可。我试着整天解决这个问题，但一切都是徒劳的。我没有在我的html表单中使用enctype，因为当我使用enctype时，我收到以下错误：

undefined Index filename

Answer 1

朋友我会给我上传图片的代码。这肯定有用。你可以参考这个。没有疑问，请问，我会帮助你

public function uploadImage() {
        $this->load->helper(array('form', 'url'));  
        $config['upload_path'] = 'assets/images/b2bcategory';
        $config['allowed_types'] = 'gif|jpg|png';
        $config['max_size'] = '1000';
        $config['max_width'] = '2024';
        $config['max_height'] = '1768';
        $config['width'] = 75;
        $config['height'] = 50;
        if (isset($_FILES['catimage']['name'])) {
            $filename = "-" . $_FILES['catimage']['name'];
            $config['file_name'] = substr(md5(time()), 0, 28) . $filename;
        }
        $config['overwrite'] = TRUE;
        $config['remove_spaces'] = TRUE;
        $field_name = "catimage";
        $this->load->library('upload', $config);
        if ($this->input->post('selsub')) {
            if (!$this->upload->do_upload('catimage')) {
                //no file uploaded or failed upload
                $error = array('error' => $this->upload->display_errors());
            } else {
                $dat = array('upload_data' => $this->upload->data());
                $this->resize($dat['upload_data']['full_path'],           $dat['upload_data']['file_name']);
            }
            $ip = $_SERVER['REMOTE_ADDR'];
            if (empty($dat['upload_data']['file_name'])) {
                $catimage = '';
            } else {
                $catimage = $dat['upload_data']['file_name'];
            }
            $data = array(            
                'ctg_image' => $catimage,
                'ctg_dated' => time()
            );
            $this->b2bcategory_model->form_insert($data);

        }
    }

Answer 2

你的道路是错的。

'upload_path' => '' .base_url(). '/assets/img/logo/',

注意：确保您的上传路径＆＃34; assets文件夹＆＃34;在主目录外面应用文件夹。您还可能需要设置文件夹权限。

尝试

'upload_path' => FCPATH . 'assets/img/logo/'

或只是

'upload_path' => './assets/img/logo/'

上传成功后访问文件信息preferences

$image_info = $this->upload->data();

echo $image_info['file_name'];

或通过模型

$this->insert_model->form_insert($data,  $image_info = array());

使用codeigniter控制器上传图像
