无法加载请求的语言文件：language / en / form_validation_lang.php [英] Unable to load the requested language file: language/en/form_validation_lang.php

问题描述

我使用codeigniter 2.1.4

因为我使用 form_validation 库进行表单验证。 / p>

当我尝试运行该函数时，会出现以下错误

：

无法加载请求的语言文件：language / en / form_validation_lang.php

我已扫描所有文件。我不是在任何文件中仍然使用或调用这个语言文件，我得到这个错误。

  function insert（）{
 $ this-> load-> library（'form_validation'）; 
 
 $ this-> form_validation-> set_rules（'username_field'，'username'，'required'）; 
 $ this-> form_validation-> set_rules（'firstname_field'，'firstname'，'required'）; 
 $ this-> form_validation-> set_rules（'lastname_field'，'lastname'，'required'）; 
 $ this-> form_validation-> set_rules（'email_field'，'email'，'required | valid_email | callback_isEmailExist'）; 
 
 if（$ this-> form_validation-> run（）== FALSE）{
 
 $ this-> create 
 
} 
} 
 
 function isEmailExist（$ email）{
 $ this-> load-> library（'form_validation'）; 
 $ is_exist = $ this-> users-> isEmailExist（$ email）; 
 
 if（$ is_exist）{
 $ this-> form_validation-> set_message（
'isEmailExist'，'电子邮件地址已存在'。
） ; 
 return false; 
} else {
 return true; 
} 
} 
  

这是什么解决方案？

解决方案

CI form_validation 库使用语言文件显示错误消息。您正在使用 required valid_email 那些错误消息写在 form_validation_lang.php / p>



form_validation 库加载语言文件（ form_validation_lang.php ）本身，无论你是否加载。你可以打开库文件，看看运行函数你会看到一行 $ this-> CI-> lang-> load（'form_validation'） ;





此文件位于 system / language / your_language / code> application / language / your_language / 。

那个错误信息说你错过了任何文件夹中的文件。下载原始CI文件，它应该在 system / language / english / 文件夹中。如果您看不到文件下载 CI并在那里恢复该文件。

I am using codeigniter 2.1.4

In that I am using form_validation library for form validation.

When I try to run that function I get following error

Unable to load the requested language file: language/en/form_validation_lang.php

I have scanned all of the files. I am not using or calling this language file in any file still and I am getting this error.

function insert(){
    $this->load->library('form_validation');

    $this->form_validation->set_rules('username_field', 'username', 'required');
    $this->form_validation->set_rules('firstname_field', 'firstname', 'required');
    $this->form_validation->set_rules('lastname_field', 'lastname', 'required');
    $this->form_validation->set_rules('email_field', 'email', 'required|valid_email|callback_isEmailExist');

    if ($this->form_validation->run() == FALSE) {

        $this->create();

    }
}

function isEmailExist($email) {
    $this->load->library('form_validation');
    $is_exist = $this->users->isEmailExist($email);

    if ($is_exist) {
        $this->form_validation->set_message(
            'isEmailExist', 'Email address is already exist.'
        );    
        return false;
    } else {
        return true;
    }
}

What is the solution for this?

解决方案

CI form_validation library uses language file for display error message.You are using required valid_email those error message is written inside form_validation_lang.php.

form_validation library loads the language file(form_validation_lang.php) itself whether you load or not.You can open the library file and look at the run function you will see a line $this->CI->lang->load('form_validation');

This file located either inside your system/language/your_language/ or application/language/your_language/.

That error message says you missed the file inside any of the folder.If you download the original CI files it should be inside system/language/english/ folder.If you don't see the file download CI and restore the file there.
