Question

我目前正在创建一个模块，用户可以将带有一些细节的图像上传到数据库，但是即使验证显示我还没有工作，我已经创建了图像的上传目录

控制器：

public function do_upload() {
        $config['upload_path'] = './uploads/';
        $config['allowed_types'] = 'gif|jpg|png';
        $config['max_size'] = '1024';
        $config['max_width'] = '1024';
        $config['max_height'] = '1024';
        $config['new_image'] = './uploads/';

        $config['overwrite'] = TRUE;
        $this->load->library('upload', $config);
        $this->form_validation->set_rules('type', 'Type', 'required');
        $this->form_validation->set_rules('school', 'School', 'required');
        $this->form_validation->set_rules('email', 'Email', 'required|valid_email');
        if (!$this->upload->do_upload() || !$this->form_validation->run()) {
            $error = array('error' => $this->upload->display_errors());
            redirect('user/payment');
        } else {
            $data = $this->upload->data();
            $this->thumb($data);
            $file = array(
                'img_name' => $data['raw_name'],
                'thumb_name' => $data['raw_name'] . '_thumb',
                'ext' => $data['file_ext'],
                'type' => $this->input->post('type'),
                'school' => $this->input->post('school'),
                'email' => $this->input->post('email'),

            );

            $data = array('upload_data' => $this->upload->data());
            $this->user_model->add_image($file);

               // redirect('user/home_register');
                $this->load->view('user/upload_success');
        }
    }
    public function thumb($data) {
        $config['image_library'] = 'gd2';
        $config['source_image'] = $data['full_path'];
        $config['create_thumb'] = TRUE;
        $config['maintain_ratio'] = TRUE;
        $config['width'] = 275;
        $config['height'] = 250;
        $config['new_image'] = './thumbs/';
        $this->load->library('image_lib', $config);
        $this->image_lib->resize();
    }

模型

function add_image($data) {
        $this->db->set('payment_date', 'NOW()', FALSE); 
        $this->db->insert('payment', $data);
    }

我在db中有8个字段 id（自动增量），payment_data，类型，学校，电子邮件，img_name，thumb_name和ext

Answer 1

尝试提供name = "userfile"

只需更换

即可

<input type="file" id="imgInp" name = "pic" required width = "10px">

与

<input type="file" id="imgInp" name = "userfile" required width = "10px">

Answer 2

尝试将图片字段名称添加到

In [69]: A
Out[69]: 
array([[ 2,  3, -6, -6, -4],
       [-5, -6, -1, -1,  3],
       [-8,  5, -7, -9, -9],
       [-3,  0,  7, -5, -6]])

In [70]: np.nanmean(np.where(A>=0,A,np.nan),axis=1)
Out[70]: array([ 2.5,  3. ,  5. ,  3.5])

将$this->upload->do_upload('pic')更改为Raw Name

使用不在codeigniter中工作的图像上传数据
