我有以下表单和控制器，它有图像上传，但一切顺利，除了文件没有上传到特定文件夹。

    </div> 

</div>
<div style="clear:both"></div>
<?php

</form>

控制器

<?php
if (!defined('BASEPATH'))
    exit('No direct script access allowed');

class Addproduct_controller extends CI_Controller
{
    function __construct()
    {
        parent::__construct();
        $this->load->helper(array('form', 'url'));
    }

    public function index()
    {
        if (isset($_POST["btn_logout"])) {

            $this->session->sess_destroy();
            $this->load->view('welcome_view');
        } else if (isset($_POST["btn_home"])) {

            $this->load->view('welcome_view');

        } else if (isset($_POST["btn_account"])) {


        } else if (isset($_POST["btn_add"])) {

            $prod_img                = 'no image';
            $config['upload_path']   = 'Public/uploads/';
            $config['allowed_types'] = 'gif|jpg|png';
            $config['max_size']      = '1024';
            $config['max_width']     = '1024';
            $config['max_height']    = '768';
            $config['encrypt_name']  = TRUE;



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


            if (!$this->upload->do_upload()) {

                //  $error = array('error' => $this->upload->display_errors());

                //$this->load->view('upload_form', $error);
                //return 'error';

            } else {
                global $prod_img;
                $data     = array(
                    'upload_data' => $this->upload->data()
                );
                $prod_img = $data->file_name;
                //  $this->load->view('upload_success', $data);
            }


            $prod_name    = $_POST["txt_pname"];
            $prod_code    = $_POST["txt_pcode"];
            $prod_price   = $_POST["txt_pprice"];
            $prod_desc    = $_POST["txt_pdesc"];
            $prod_options = $_POST["txt_poptions"];



            $this->load->model('product_model');
            $addproduct_result = $this->product_model->addProduct($prod_code, $prod_name, $prod_price, $prod_desc, $prod_img);

            if ($addproduct_result == true) {

                echo "Added Successfully";

            } else {

                echo "Failed";
            }

        }

    }





}

然后我尝试添加以下代替普通标签。

<?php
$this->load->helper('form');
?>


<?php
echo form_open_multipart(base_url().'index.php/addproduct_controller');
?>

它给我一个错误

A PHP Error was encountered

Severity: Notice

Message: Trying to get property of non-object

Filename: controllers/addproduct_controller.php

Line Number: 53

请帮我解决这个问题，或者告诉我我犯了哪些错误。

Answer 1

你的from标签中缺少

enctype属性。

在表单标记中添加enctype="multipart/form-data"

或

在CI中，使用form_open_multipart函数生成表单标记

根据评论中的讨论，请按以下方式更新您的代码。

$data = array( 'upload_data' => $this->upload->data() ); $prod_img = $data["upload_data"]->file_name;

Answer 2

您错过了包含表单属性以上传文件

添加enctype =＆＃34; multipart / form-data＆＃34;在您的表单标签

Answer 3

您已在表单创建中创建Fragment duedateFrag = new FieldVisitFragment(); FragmentTransaction ft = fragmentActivity.getSupportFragmentManager().beginTransaction(); ft.replace(android.R.id.tabcontent, duedateFrag); ft.commit();表单但未添加文件上传标记。

在表单标记中添加html。

enctype="multipart/form-data"

Codeigniter文件无法上传
