我在控制器Laravel中有默认验证规则:
$validator = Validator::make($request->all(), [
'email' => 'required|email',
'phone' => 'required|numeric',
'code' => 'required|string|min:3|max:4',
'timezone' => 'required|numeric',
'country' => 'required|integer',
'agreement' => 'accepted'
]);
我尝试了这个,但不知道如何在函数内传递一些参数:
public function boot()
{
Validator::extend('phone_unique', function($attribute, $value, $parameters) {
return substr($value, 0, 3) == '+44';
});
}
如何根据自己的规则扩展此验证?例如,我需要验证输入的连接:
$phone = $request->code.' '.$request->phone
检查数据库中是否存在$phone
我想使用这种方法:
> $validator->sometimes('phone', 'required|alpha_dash|max:25', function
> ($input) {
> if ((Auth::user()->phone == $input->phone)) {
> return false;
>
> } else {
>
> $t = User::where("phone", $input->phone)->get();
> return ($t->count() > 0) ? false : false;
>
> }
> });
它在(True, False)
里面的所有条件下都不起作用。
我添加了新的验证nickname_unique
:
$validator = Validator::make($request->all(), [
'email' => 'required|email',
'code' => 'required|string|min:3|max:4',
'phone' => 'required|phone_unique',
'timezone' => 'required|numeric',
'country' => 'required|integer',
'nickname' => 'required|alpha_dash|max:25',
'agreement' => 'accepted'
], [
'phone_unique' => 'Phone already exists!',
'nickname_unique' => 'Nickname is busy!',
]);
它不起作用,甚至不在以下呼叫验证规则:
Validator::extend('nickname_unique', function ($attribute, $value, $parameters, $validator) {
dd("Here");
});

您可以在AppServiceProvider
内定义自定义验证器,如下所示:
<?php
namespace App\Providers;
use Illuminate\Support\ServiceProvider;
use Illuminate\Support\Facades\Validator;
class AppServiceProvider extends ServiceProvider
{
/**
* Bootstrap any application services.
*
* @return void
*/
public function boot()
{
Validator::extend('phone_unique', function ($attribute, $value, $parameters, $validator) {
$inputs = $validator->getData();
$code = $inputs['code'];
$phone = $inputs['phone'];
$concatenated_number = $code . ' ' . $phone;
$except_id = (!empty($parameters)) ? head($parameters) : null;
$query = User::where('phone', $concatenated_number);
if(!empty($except_id)) {
$query->where('id', '<>', $except);
}
return $query->exists();
});
/**
* Register the service provider.
*
* @return void
*/
public function register()
{
//
}
}
通过访问
,您可以获得传递给验证者的所有输入$validator
属性 -getData()
您可以在自定义验证规则之后(仅在colon
之后)向规则数组中添加一个额外参数,如下所示:
'phone' => 'required|phone_unique:1',
在将条目检入db
时,传递要忽略的id
自定义验证器Closure接收四个参数:正在验证的$attribute
的名称,属性的$value
,传递给规则的$parameters
数组以及Validator实例
现在您可以像这样调用验证器:
$validator = Validator::make($request->all(), [
'email' => 'required|email',
'code' => 'required|string|min:3|max:4',
'phone' => 'required|phone_unique:1',
'timezone' => 'required|numeric',
'country' => 'required|integer',
'agreement' => 'accepted'
], [
'phone_unique' => 'Phone already exists!', // <---- pass a message for your custom validator
]);

我正在写这个答案,因为我相信很多人都在为这个话题寻找一些好的答案。所以我决定分享我用于预订网站的代码,我想在那里检查IS NOT_adate&gt; DEPARTURE_DATE。
我的Laravel版本是5.3.30
public function postSolitudeStepTwo(Request $request)
{
$rules = [
'arrival_date' => 'required|date',
'departure_date' => 'required|departure_date_check',
'occasional_accompaniment_requested' => 'required|integer',
'accommodation' => 'required|integer',
'are_you_visiting_director' => 'required|integer',
];
if ($request->input('are_you_visiting_director') == 1) {
$rules['time_in_lieu'] = 'required|integer';
}
$messages = [
'departure_date_check' => 'Departure date can\'t be smaller then Arrival date.Please check your dates.'
];
$validation = validator(
$request->toArray(),
$rules,
$messages
);
//If validation fail send back the Input with errors
if($validation->fails()) {
//withInput keep the users info
return redirect()->back()->withInput()->withErrors($validation->messages());
} else {
MySession::setSessionData('arrival_date', $request);
MySession::setSessionData('departure_date', $request);
MySession::setSessionData('occasional_accompaniment_requested', $request);
MySession::setSessionData('accommodation', $request);
MySession::setSessionData('are_you_visiting_director', $request);
MySession::setSessionData('time_in_lieu', $request);
MySession::setSessionData('comment_solitude_step2_1', $request);
//return $request->session()->all();
return redirect("/getSolitudeStepThree");
}
}
我的控制器是 StepController ,我已经声明了一个名为postSolitudeStepTwo的方法。我宣布规则并在出发日期通知我们有required|departure_date_check
规则。这将是
app/Providers/AppServiceProvider.php
那里的代码如下:
public function boot()
{
Validator::extend('departure_date_check', function ($attribute, $value, $parameters, $validator) {
$inputs = $validator->getData();
$arrivalDate = $inputs['arrival_date'];
$departureDate = $inputs['departure_date'];
$result = true;
if ($arrivalDate > $departureDate) {
$result = false;
}
return $result;
});
}
由于Laravel documentation 5.3 Custom validation rules我们需要扩展Validator外观,所以该方法的签名必须是:
Validator::extend(name_of_the_function, function ($attribute, $value, $parameters, $validator) {
我相信其余的都很明确。
希望它会对某人有所帮助。

$messsages = array(
'email.required'=>'Email is Required',
'phone.required'=>'Phone number is Required',
);
$rules = array(
'email' => 'required',
'phone' => 'required',
);
$validator = Validator::make(Input::all(), $rules,$messsages);
if ($validator->fails()):
$this->throwValidationException($request, $validator);
endif;
