[英]Custom Laravel validation messages
I'm trying to create customized messages for validation in Laravel 5. Here is what I have tried so far:我正在尝试在 Laravel 5 中创建用于验证的自定义消息。这是我到目前为止所尝试的:
$messages = [
'required' => 'Harap bagian :attribute di isi.',
'unique' => ':attribute sudah digunakan',
];
$validator = Validator::make($request->all(), [
'username' => array('required','unique:Userlogin,username'),
'password' => 'required',
'email' => array('required','unique:Userlogin,email'),$messages
]);
if ($validator->fails()) {
return redirect('/')
->withErrors($validator) // send back all errors to the login form
->withInput();
} else {
return redirect('/')
->with('status', 'Kami sudah mengirimkan email, silahkan di konfirmasi');
}
But it's not working.但它不起作用。 The message is still the same as the default one.该消息仍与默认消息相同。 How can I fix this, so that I can use my custom messages?我该如何解决这个问题,以便我可以使用我的自定义消息?
Laravel 5.7.* Laravel 5.7.*
Also You can try something like this.你也可以尝试这样的事情。 For me is the easiest way to make custom messages in methods when you want to validate requests:对我来说,当您想验证请求时,在方法中制作自定义消息的最简单方法:
public function store()
{
request()->validate([
'file' => 'required',
'type' => 'required'
],
[
'file.required' => 'You have to choose the file!',
'type.required' => 'You have to choose type of the file!'
]);
}
If you use $this->validate()
simplest one, then you should write code something like this..如果你使用$this->validate()
最简单的一个,那么你应该写这样的代码。
$rules = [
'name' => 'required',
'email' => 'required|email',
'message' => 'required|max:250',
];
$customMessages = [
'required' => 'The :attribute field is required.'
];
$this->validate($request, $rules, $customMessages);
You can provide custom message like :您可以提供自定义消息,例如:
$rules = array(
'URL' => 'required|url'
);
$messages = array(
'URL.required' => 'URL is required.'
);
$validator = Validator::make( $request->all(), $rules, $messages );
if ( $validator->fails() )
{
return [
'success' => 0,
'message' => $validator->errors()->first()
];
}
or要么
The way you have tried, you missed Validator::replacer()
, to replace the :variable
您尝试过的方式,您错过了Validator::replacer()
来替换:variable
Validator::replacer('custom_validation_rule', function($message, $attribute, $rule, $parameters){
return str_replace(':foo', $parameters[0], $message);
});
You can read more from here and replacer from here你可以阅读更多从这里和替代品从这里
For Laravel 8.x , 7.x , 6.x对于 Laravel 8.x , 7.x , 6.x
With the custom rule defined, you might use it in your controller validation like so :定义自定义规则后,您可以在控制器验证中使用它,如下所示:
$validatedData = $request->validate([
'f_name' => 'required|min:8',
'l_name' => 'required',
],
[
'f_name.required'=> 'Your First Name is Required', // custom message
'f_name.min'=> 'First Name Should be Minimum of 8 Character', // custom message
'l_name.required'=> 'Your Last Name is Required' // custom message
]
);
For localization you can use :对于本地化,您可以使用:
['f_name.required'=> trans('user.your first name is required'],
Hope this helps...希望这可以帮助...
$rules = [
'username' => 'required,unique:Userlogin,username',
'password' => 'required',
'email' => 'required,unique:Userlogin,email'
];
$messages = [
'required' => 'The :attribute field is required.',
'unique' => ':attribute is already used'
];
$request->validate($rules,$messages);
//only if validation success code below will be executed
//Here is the shortest way of doing it.
$request->validate([
'username' => 'required|unique:Userlogin,username',
'password' => 'required',
'email' => 'required|unique:Userlogin,email'
],
[
'required' => 'The :attribute field is required.',
'unique' => ':attribute is already used'
]);
//The code below will be executed only if validation is correct.
You can also use the methods setAttributeNames()
and setCustomMessages()
, like this:您还可以使用setAttributeNames()
和setCustomMessages()
,如下所示:
$validation = Validator::make($this->input, static::$rules);
$attributeNames = array(
'email' => 'E-mail',
'password' => 'Password'
);
$messages = [
'email.exists' => 'No user was found with this e-mail address'
];
$validation->setAttributeNames($attributeNames);
$validation->setCustomMessages($messages);
For those who didn't get this issue resolve (tested on Laravel 8.x):对于那些没有解决这个问题的人(在 Laravel 8.x 上测试):
$validated = Validator::make($request->all(),[
'code' => 'required|numeric'
],
[
'code.required'=> 'Code is Required', // custom message
'code.numeric'=> 'Code must be Number', // custom message
]
);
//Check the validation
if ($validated->fails())
{
return $validated->errors();
}
$rules = [
'name' => 'required',
'email' => 'required|email',
'message' => 'required|max:250',
];
$customMessages = [
'required' => 'The :attribute field is required.',
'max' => 'The :attribute field is may not be greater than :max.'
];
$this->validate($request, $rules, $customMessages);
run below command to create a custom rule on Laravel运行以下命令以在 Laravel 上创建自定义规则
ı assuming that name is CustomRule我假设名称是 CustomRule
php artisan make:rule CustomRule
and as a result, the command was created such as PHP code结果,该命令被创建,例如PHP代码
if required keyword hasn't on Rules,That rule will not work如果 required 关键字没有在规则上,该规则将不起作用
<?php
namespace App\Rules;
use Illuminate\Contracts\Validation\Rule;
class CustomRule implements Rule
{
/**
* Create a new rule instance.
*
* @return void
*/
public function __construct()
{
//
}
/**
* Determine if the validation rule passes.
*
* @param string $attribute
* @param mixed $value
* @return bool
*/
public function passes($attribute, $value)
{
//return true or false
}
/**
* Get the validation error message.
*
* @return string
*/
public function message()
{
return 'The validation error message.';
}
}
and came time using that first, we should create a request class if we have not并首先使用它,如果我们还没有,我们应该创建一个请求类
php artisan make:request CustomRequest
CustomRequest.php自定义请求.php
<?php
namespace App\Http\Requests\Payment;
use App\Rules\CustomRule;
use Illuminate\Foundation\Http\FormRequest;
class CustomRequest extends FormRequest
{
/**
* Get the validation rules that apply to the request.
*
* @return array
*/
public function rules(): array
{
return [
'custom' => ['required', new CustomRule()],
];
}
/**
* @return array|string[]
*/
public function messages(): array
{
return [
'custom.required' => ':attribute can not be empty.',
];
}
}
and on your controller, you should inject custom requests to the controller在您的控制器上,您应该向控制器注入自定义请求
your controller method你的控制器方法
class FooController
{
public function bar(CustomRequest $request)
{
}
}
In the case you are using Request as a separate file:如果您使用 Request 作为单独的文件:
public function rules()
{
return [
'preparation_method' => 'required|string',
];
}
public function messages()
{
return [
'preparation_method.required' => 'Description is required',
];
}
Tested out in Laravel 6+在 Laravel 6+ 中测试
you can customise the message for different scenarios based on the request.您可以根据请求自定义不同场景的消息。
Just return a different message with a conditional.只需返回带有条件的不同消息。
<?php
namespace App\Rules;
use App\Helpers\QueryBuilderHelper;
use App\Models\Product;
use Illuminate\Contracts\Validation\Rule;
class ProductIsUnique implements Rule
{
private array $attributes;
private bool $hasAttributes;
/**
* Create a new rule instance.
*
* @return void
*/
public function __construct(array $attributes)
{
$this->attributes = $attributes;
$this->hasAttributes = true;
}
/**
* Determine if the validation rule passes.
*
* @param string $attribute
* @param mixed $value
* @return bool
*/
public function passes($attribute, $value)
{
$brandAttributeOptions = collect($this->attributes['relationships']['brand-attribute-options']['data'])->pluck('id');
$query = Product::query();
$query->when($brandAttributeOptions->isEmpty(), function ($query) use ($value) {
$query->where('name', $value);
$this->hasAttributes = false;
});
return !$query->exists();
}
/**
* Get the validation error message.
*
* @return string
*/
public function message()
{
return ($this->hasAttributes) ? 'The Selected attributes & Product Name are not unique' : 'Product Name is not unique';
}
}
