改进这个问题

路由文件添加路由。 在我们下面的图片上传示例中

$route['image-upload'] = 'ImageUpload';
$route['image-upload/post']['post'] = 'ImageUpload/uploadImage';

然后步骤：在 application/controllers/ImageUpload.php 中创建一个“ImageUpload”控制器

<?php


class ImageUpload extends CI_Controller{
    public function __construct(){
        parent::__construct();
        $this->load->helper('url');
    }
    
    public function index(){
        $this->load->view('imageUploadForm');
    }

    public function uploadImage(){

        $data = [];

        $count = count($_FILES['files']['name']);

       for ($i=0; $i< $count; $i++) { 
        if(!empty($_FILES['files']['name'])){
            $_FILES['file']['name'] = $_FILES['files']['name'][$i];
            $_FILES['file']['type'] = $_FILES['file']['type'][$i];
            $_FILES['file']['tmp_name'] = $_FILES['file']['tmp_name'][$i];
            $_FILES['file']['error'] = $_FILES['file']['error'][$i];
            $_FILES['file']['size'] = $_FILES['file']['size'][$i];

            $config['upload_path'] = 'uploads/';
            $config['allowed_types'] = 'jpg|jpeg|png|gif';
            $config['max_size'] = '5000';
            $config['file_name'] = $_FILES['files']['name'][$i];
            
            $this->load->library('upload',$config);

            if($this->upload->do_upload('file')){
                $uploadData = $this->upload->data();
                $filename = $uploadData['file_name'];

                $data['totalFiles'][] = $filename;
            }
        }
       }
       $this->load->view('imageUploadForm',$data);
    }
}
?>

然后第三步：在application/views/中创建一个视图文件imageUploadForm.php

<!DOCTYPE html>
<html>
    <head>
        <title>Example of Upload Multiple Files and Images in codeigniter</title>
    </head>
    <body>
    <h1>Upload Multiple file and image in codeigniter</h1>
    
    <strong><?php if(isset($totalFiles)) echo "Successfully upload ".count($totalFiles)." files"; ?></strong>

    <form method="POST" action="image-upload/post" enctype="multipart/form-data">

        <input type="file" name="files[]" multiple="" id="">
        <br><br>
        <input type="submit" value="Upload" name="upload" />


    </form>

    </body>
</html>

然后我运行第 23、24、25、26 行中显示的代码错误
