CSV 文件上传不适用于 Codeigniter

我正在使用下面的代码上传 csv 文件。它总是说“无效文件错误”。我该如何解决这个问题？

这是我的表格：

<form name="bulk_dealer" action="<?= base_url() ?>admin/add_bulk_user" method="post" accept-charset="utf-8"  enctype="multipart/form-data">  
    <ul>  
        <ul>
            <li class="ui-field"><label for="csvfile">Upload dealer id file( *only .csv) :</label></li> 
            <li class="ui-input"><input type="file" name="csvfile" value="" placeholder="" required=""></li>  
            <li><input type="submit" value="Upload" name="Upload" class="ui-submit"></li>  
        </ul>
    </ul>  
</form>

这是我的控制器

function add_bulk_user() {
    $data['add_bulk_user_errors'] = NULL;
    $data['add_bulk_user_success'] = NULL;       

    if ($this->input->post() !== FALSE) {
        $config_arr = array(
            'upload_path' => './uploads/csv/',
            'allowed_types' => 'text/plain|text/csv|csv',
            'max_size' => '2048',
            'max_width' => '1024',
            'max_height' => '768',
            'encrypt_name' => true,
            'file_name' => 'dealer'
        );

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

        if (!$this->upload->do_upload('csvfile')) {
            $data['add_bulk_user_errors'] = $this->upload->display_errors(); // this isn't working                
        } else {
            $csvfilepath = "uploads/csv/" . $config_arr['file_name'];
            $this->addfromcsv($csvfilepath);
            $data['qs'] = $this->upload->data();
            $row = 1;

            if (($handle = fopen("./uploads/csv/dealer.csv", "r")) !== FALSE) {
                while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
                    $num = count($data);
                    $row++;
                    for ($c = 0; $c < $num; $c++) {

                        $this->load->model("login_model");
                        $is_esist = $this->login_model->check_is_exist($data[$c]);
                        if ($is_esist) {

                        } else {
                            $this->login_model->set_login($data[$c], 'dealer@ceat123');
                        }
                    }
                }
                fclose($handle);
            }

            $data['add_bulk_user_success'] = "File Uploaded Successfully";
        }

        $data['main_content'] = 'admin/add';

        $this->load->view('admin_layout', $data);
        redirect('admin/add_bulk_user', 'refresh');
    } else {
        $data['main_content'] = 'admin/add';
        $this->load->view('admin_layout', $data);
    }
}

'allowed_types'=> 'csv',

在您的根目录上转到application -> config -> mimes.php在 csv 中添加'text/plain'

希望这对你有帮助。
