提前感谢您给我的帮助，我会解释我的情况。
基于教程
我正在尝试制作一个允许我上传 CSV 文件、解析此文档并将数据插入数据库的页面。到目前为止，我已经编写了以下代码：
<?php
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'] = 'csv';
$config['max_size'] = '5000';
$with = ' ';
$replace = '"';
$this->load->library('upload', $config);
$this->load->database();
if ( ! $this->upload->do_upload())
{
$error = array('error' => $this->upload->display_errors());
$this->load->view('upload_form', $error);
}
else
{
//Insert file info into database
$data = array('upload_data' => $this->upload->data());
$userfile = $data['upload_data']['file_name'];
$this->load->library('csvreader');
$filePath1 = './uploads/';
$filePath2 = $data['upload_data']['file_name'];
$filePath = $filePath1 . $filePath2;
$data['csvData'] = $this->csvreader->parse_file($filePath);
foreach($data['csvData'] as $cd){
$results_array = array(
'Parolachiave' => $cd['Parola chiave'],
'Concorrente' => $cd['Concorrente'],
'Motorediricerca' => $cd['Motore di ricerca'],
'Posizione' => $cd['Posizione'],
'Paginaweb' => $cd['Pagina web'],
'Modifiche' => $cd['Modifiche']
);
$this->db->set($results_array);
$this->db->insert('data', $results_array);
}
}
}
}
?>
我使用谷歌浏览器并给我这个错误：当我尝试在 index.php / 上传中输入时，HTTP 错误 500（内部服务器错误）。我已经在 Codeigniter 的根目录中的 config/database.php 中声明了我的数据库。我正在尝试将我的问题的解决方案联网，但我仍然没有弄清楚我错在哪里。谢谢你。
这是我的图书馆/csvreader.php
