CI form_validationlibrary uses language file for display error message.You are using requiredvalid_emailthose error message is written inside form_validation_lang.php.
CIform_validation库使用语言文件来显示错误信息。你正在使用requiredvalid_email那些写在里面的错误信息form_validation_lang.php。
form_validationlibrary 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 $this->CI->lang->load('form_validation');
form_validation库加载语言文件（form_validation_lang.php）本身，无论你加载与否。你可以打开库文件并查看运行函数你会看到一行$this->CI->lang->load('form_validation');
This file located either inside your system/language/your_language/or application/language/your_language/.
此文件位于您的system/language/your_language/或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 downloadCI and restore the file there.
该错误消息表示您错过了任何文件夹内的文件。如果您下载原始 CI 文件，它应该在system/language/english/文件夹内。如果您没有看到文件，请下载CI 并在那里恢复文件。

there are two locations whith language files
1. in the system/languagefolder
2. in the application/languagefolder
语言文件有两个位置 1. 在system/language文件夹中 2. 在application/language文件夹中
For formvalidation CI uses the system/languagefolder
对于表单验证 CI 使用system/language文件夹
in your config.php (in the application/config) you specify wich language folder you want to use.
在您的 config.php （在application/config）中，您指定要使用的语言文件夹。
So, open your config file and look for
因此，打开您的配置文件并查找
$config['language'] = 'en';
look into your system/languagefolder and look if there is a folder named "en" and if there is a form_validation_lang.phpfile in it.
查看您的system/language文件夹，看看是否有名为“en”的文件夹以及其中是否有form_validation_lang.php文件。
if not, I think there is a folder named english.
then the solutions would be to change the 'en'in your config to english.
如果没有，我认为有一个名为english. 那么解决方案是将'en'配置中的更改为english.

Go to application/config/config.phpyou should have $config['language'] = 'en';.
Change it to $config['language'] = 'english';.
去application/config/config.php你应该有$config['language'] = 'en';。将其更改为$config['language'] = 'english';.
