Question

我写了代码

$this->session->set_flashdata('nt_changed_msg','<div class="alert alert-danger text-center">'.lang('tekparerr').'</div>');
redirect('user/continueregistration');

在我的User.php控制器中。但是，它给出了一个错误：

无法加载请求的语言文件：语言/阿塞拜疆/ form_validation_lang.php

实际上，我无法理解，如果我没有请求form_validation_lang.php并且我的语言文件夹中没有此文件，为什么Codeigniter需要它？我该如何解决这个问题？

我的挂钩文件：

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

class LanguageLoader
{
    function initialize() {
        $ci =& get_instance();
        $ci->load->helper('language');
        $siteLang = $ci->session->userdata('site_lang');
        $ci->config->set_item('language', $siteLang);
        if ($siteLang) {
            $ci->lang->load('header',$siteLang);
            $ci->lang->load('footer',$siteLang);
            $ci->lang->load('index',$siteLang);
            $ci->lang->load('courses',$siteLang);
            $ci->lang->load('parsleyvalidator',$siteLang);
            $ci->lang->load('blog',$siteLang);
            $ci->lang->load('instructors',$siteLang);
            $ci->lang->load('continuereg',$siteLang);
            $ci->lang->load('about',$siteLang);
            $ci->lang->load('contact',$siteLang);
            $ci->lang->load('controllers',$siteLang);
            $ci->lang->load('form_validation',$siteLang);
            $ci->lang->load('mailtemplate',$siteLang);
        } else {
            $ci->lang->load('header','azerbaijani');
            $ci->lang->load('footer','azerbaijani');
            $ci->lang->load('index','azerbaijani');
            $ci->lang->load('courses','azerbaijani');
            $ci->lang->load('parsleyvalidator','azerbaijani');
            $ci->lang->load('blog','azerbaijani');
            $ci->lang->load('instructors','azerbaijani');
            $ci->lang->load('continuereg','azerbaijani');
            $ci->lang->load('about','azerbaijani');
            $ci->lang->load('contact','azerbaijani');
            $ci->lang->load('controllers','azerbaijani');
            $ci->lang->load('form_validation','azerbaijani');
            $ci->lang->load('mailtemplate','azerbaijani');
        }
        // cierrors
    }
}

如果你查看system / libraries / Form_validation.php，你会看到以下行（450）：

$this->CI->lang->load('form_validation');

CodeIgniter表单验证不允许您专门为表单验证指定语言，并且它需要一个lang文件，因此您最好的选择是创建一个。

创建文件application/language/azerbaijani/form_validation_lang.php，然后在该文件中复制system/language/english/form_validation_lang.php的内容。由于您最好将英语翻译成阿塞拜疆语，请更新您的新阿塞拜疆语/ form_validation_lang.php文件，以便内容采用阿塞拜疆语。

供参考，这是form_validation_lang.php文件的英文相关内容：
