Question

我的codeigniter上传表格有问题

View.php我在Codeigniter文档中找到了这段代码，我不知道问题出在哪里..

    <?php echo $error;?>
<?php echo form_open_multipart('upload/do_upload');?>
<input type="file" name="userfile" size="20" />
<br /><br />
<input type="submit" value="upload" />
</form>

upload.php就是upload.php

<?php
 defined('BASEPATH') OR exit('No direct script access allowed');
    class Upload extends CI_Controller {

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

function index()
{
    $this->load->view('upload_form', array('error' => ' ' ));
}

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

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

    if ( ! $this->upload->do_upload())
    {
        $error = array('error' => $this->upload->display_errors());

        $this->load->view('upload_form', $error);
    }
    else
    {
        $data = array('upload_data' => $this->upload->data());

        $this->load->view('upload_success', $data);
    }
}
  }
     ?>

当我上传一些图片ci给我

    A PHP Error was encountered

Severity: Notice

Message: Undefined property: Upload::$upload

Filename: controllers/Upload.php

Line Number: 52

Backtrace:
    Fatal error: Call to a member function do_upload() on a non-object in

问题出在哪里？谢谢

修改

从您发布的链接中，我按照上传文件的指南进行操作，并且完美无缺。

确保正确设置CI：

必须将文件夹application和system以及文件index.php上传到您正常工作的网络服务器，然后您必须创建一个名为uploads的文件夹，确保此文件夹是可由适当的用户写入，对于我的系统，它是www-data。我在linux上使用apache2，所以我的webroot是var/www。

所以你应该在主文件夹中看到：

应用

系统

上传

的index.php

完成后，您将转到：

localhost/index.php/upload/或index.php/upload/的正确路径并再次测试。
