Add a custom validation error message laravel
提问by BOTJr.
I can do something like this to validate something on the controller.
我可以做这样的事情来验证控制器上的某些东西。
$this->validate($request,[
'myinput'=>'regex:some pattern'
]);
and the output of this would be something like this
并且它的输出将是这样的
The myinput format is invalid.
myinput 格式无效。
What i want was to show something of my own message
我想要的是展示我自己的信息
Only some pattern allowed
只允许某些模式
How do i achieve this on laravel?
我如何在 Laravel 上实现这一目标？

There are many techniques to customize validator messages.
有许多技术可以自定义验证器消息。
Validate inside the controller
在控制器内部验证
It would be looked like this
它看起来像这样
$validate = Validator::make($request->all(), [
'name'=>'required|max:120',
'email'=>'required|email|unique:users,email,'.$id,
'password'=>'nullable|min:6|confirmed'
],
[
'name.required' => 'User name must not be empty!',
'name.max' => 'The maximun length of The User name must not exceed :max',
'name.regex' => 'Use name can not contain space',
'email.required' => 'Email must not be empty!',
'email.email' => 'Incorrect email address!',
'email.unique' => 'The email has already been used',
'password.min' => 'Password must contain at least 6 characters',
'password.confirmed' => 'Failed to confirm password'
]);
Second apprach: using InfyOm Laravel Generator
第二种方法：使用 InfyOm Laravel Generator
I like this approach the most. It provides useful tools for generating such as Controller, Models, Views, API etc.
And yet, create and update Requestfile. in which the Request file is using Illuminate\Foundation\Http\FormRequestwhere this class is extended from Illuminate\Http\Request.
It is mean that we can access Requestin this file and perform validating for the incoming requests.
Here is the most interesting part to me.
The generated request file contains rulesfunction, for example like this
我最喜欢这种方法。它提供了有用的工具来生成诸如控制器、模型、视图、API 等。然而，创建和更新Request文件。其中请求文件正在使用Illuminate\Foundation\Http\FormRequest，该类是从Illuminate\Http\Request.
这意味着我们可以访问该文件中的Request并对传入的请求执行验证。
这是对我来说最有趣的部分。
生成的请求文件包含规则函数，例如像这样
public function rules() {
return [
'name' => 'required|unique:flights,name|max:20',
'airline_id' => 'nullable|numeric|digits_between:1,10',
];
}
This function actually returns the validator-rules and validate them against the inputs.
And you can override function messagesfrom Illuminate\Foundation\Http\FormRequestto customize the error message as you need:
这个函数实际上返回验证器规则并根据输入验证它们。您可以覆盖来自Illuminate\Foundation\Http\FormRequest 的函数消息以根据需要自定义错误消息：
public function messages()
{
return [
'required' => "This field is required",
\... etc
];
}
Nonetheless, you can do many nore with the generated request files, just refer to file in vendor folder vendor/laravel/framework/src/Illuminate/Foundation/Httpfrom your project.
Here is the Infyom github link InfyOmLabs - laravel-generator
尽管如此，您可以对生成的请求文件做很多事情，只需vendor/laravel/framework/src/Illuminate/Foundation/Http从您的项目中引用 vendor 文件夹中的文件即可。

You can add custom validation messages to language files, like resources/lang/en/validation.php.
您可以将自定义验证消息添加到语言文件，例如resources/lang/en/validation.php.
Another way to do that, from docs:
另一种方法，从文档：
'custom' => [
'email' => [
'regex' => 'Please use your company email address to register. Webmail services are not permitted.'
],
'lawyer_legal_fields' => [
'number_of_areas' => 'You\'re not allowed to select so many practice areas'
],
],
You may customize the error messages used by the form request by overriding the messages method.
您可以通过覆盖 messages 方法自定义表单请求使用的错误消息。
public function messages()
{
return [
'title.required' => 'A title is required',
'body.required' => 'A message is required',
];
}
