我的观看页面是

<html>
<head>
<title>Upload Form</title>
</head>
<body>

<?php // echo $error;?>

<?php echo form_open_multipart('Upload_c/my_test');?>

<input type="file" name="file_name" size="20" />

<br /><br />

<input type="submit" name="up" value="upload" />

</form>

</body>

当我点击视图页面中的上传按钮时，它显示的错误如下

请在此示例中尝试此操作您不需要任何库，它将在没有任何库的情况下工作 -

我的查看文件（index.php） -

<form class="form-horizontal well" action="<?php echo base_url(); ?>index.php/welcome/import" method="post" name="upload_excel" enctype="multipart/form-data">
<input type="file" name="file" id="file" class="input-large">
<button type="submit" id="submit" name="Import" class="btn btn-primary button-loading">Upload</button>
</form>

我的模型（welcome_model.php） -

<?php 
class Welcome_model extends CI_Model
    {
        public function insertCSV($data)
            {
                $this->db->insert('subject', $data);
                return $this->db->insert_id();
            }
    }
?>

我的控制器（welcome.php） -

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

class Welcome extends CI_Controller {

    public function index()
        {
            $this->load->model('welcome_model');
            $this->load->view('index');
        }

    public function import()
        {
          if(isset($_POST["Import"]))
            {
                $filename=$_FILES["file"]["tmp_name"];
                if($_FILES["file"]["size"] > 0)
                  {
                    $file = fopen($filename, "r");
                     while (($emapData = fgetcsv($file, 10000, ",")) !== FALSE)
                     {
                            $data = array(
                                'SUBJ_CODE' => $emapData[1],
                                'SUBJ_DESCRIPTION' => $emapData[2],
                                'UNIT' => $emapData[3],
                                'PRE_REQUISITE' => $emapData[4],
                                'COURSE_ID' => $emapData[5],
                                'AY' => $emapData[6],
                                'SEMESTER' => $emapData[7],
                                );
                        $this->load->model('welcome_model');
                        $insertId = $this->welcome_model->insertCSV($data);
                     }
                    fclose($file);
                    redirect('welcome/index');
                  }
            }
        }
}

请尝试这个它肯定会工作..
