Question

我尝试上传图像并将其插入数据库，但无法正常工作。页面上没有显示任何错误，图像也没有上传或插入数据库，请给我一个解决方案，该如何解决这个问题？

我的代码在这里，控制器的代码在这里，enter code here

public function add_product()
{
            $config['upload_path'] = './uploads/';
            $config['allowed_types'] = 'gif|jpg|png|jpeg';
            $config['max_size'] = 100;
            $config['max_width'] = 1024;
            $config['max_height'] = 768;

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

            $input_name = "product_image";
            if (!$this->upload->do_upload($input_name))
            {
                $data['items'] = $this->data_model->get_data_info('product_id','product');
                $this->load->view('product',$data);
            }
            else
            {
                   $image_info = $this->upload->data();
                       $data = array(
                            'product_name'=>$this->input->post('product'),
                            'product_pic'=>$image_info['file_name'],
                             'description'=>$this->input->post('description')
                            );

                            $query = $this->data_model->add_data($data,'product');
                            if($query == TRUE){
                                echo "product added";
                                $data['items'] = $this->data_model->get_data_info('product_id','product');
                                $this->load->view('product',$data);
                            }else{
                                echo"product already exists";
                                $data['items'] = $this->data_model->get_data_info('product_id','category');
                                $this->load->view('product',$data);
                            } 

                }
}

型号：

    public function add_data($data,$table){
        $result = $this->db->get_where($table,$data);
        $query = (bool)$result->num_rows();
        if(!$query){
           if($this->db->insert($table,$data)){
                return TRUE;
            }else{
                return FALSE;
            } 
        }else{
            return FALSE;
        }
}

控制器代码

 function add_product() {
    if (!is_dir('./Uploads/')) {
        mkdir('./Uploads/', 0777, TRUE);
    }
    if (!empty($_FILES['product_image'])) {
        $config['upload_path'] = './Uploads/';
        $config['allowed_types'] = '*';
        $config['max_size'] = '100';
        $config['max_width'] = '1024';
        $config['max_height'] = '768';
        $config['overwrite'] = TRUE;
        $config['file_name'] = date('U') . '_' . $_FILES['product_image']['name'];
        $this->load->library('upload', $config);
        $this->upload->initialize($config);
        if (!$this->upload->do_upload('product_image')) {
            $error = array('error' => $this->upload->display_errors());
            print_r($error);
            die;
        } else {
            if ($this->upload->do_upload('product_image')) {
                $image_data = $this->upload->data();
                $full_path = $config['file_name'];
                $data["product_pic"] = $full_path;
                $query = $this->data_model->add_data($data, 'product');
                if ($res == TRUE) {
                    echo "product added";
                    $data['items'] = $this->data_model->get_data_info('product_id', 'product');
                    $this->load->view('product', $data);
                } else {
                    echo"product already exists";
                    $data['items'] = $this->data_model->get_data_info('product_id', 'category');
                    $this->load->view('product', $data);
                }
            }
        }
    }
    $this->load->view('product');
}

型号代码

function add_data($data, $table) {    
if ($query = $this->db->insert($table,$data)) {
    $insert_id = $this->db->insert_id();
    return $insert_id;
} else {
    return false;
}
