Laravel validation OR
提问by Ian
I have some validation that requires a url ora route to be there but notboth.
我有一些验证需要一个 url或一个路由，但不能同时存在。
$this->validate($request, [
'name' => 'required|max:255',
'url' => 'required_without_all:route|url',
'route' => 'required_without_all:url|route',
'parent_items'=> 'sometimes|required|integer'
]);
I have tried using required_withoutand required_without_allhowever they both get past the validation and I am not sure why.
我试过使用required_without，required_without_all但是它们都通过了验证，我不知道为什么。
routeis a rule in the routefield
route是该route领域的规则

I think the easiest way would be creation your own validation rule. It could looks like.
我认为最简单的方法是创建自己的验证规则。它可能看起来像。
Validator::extend('empty_if', function($attribute, $value, $parameters, Illuminate\Validation\Validator $validator) {
$fields = $validator->getData(); //data passed to your validator
foreach($parameters as $param) {
$excludeValue = array_get($fields, $param, false);
if($excludeValue) { //if exclude value is present validation not passed
return false;
}
}
return true;
});
And use it
并使用它
$this->validate($request, [
'name' => 'required|max:255',
'url' => 'empty_if:route|url',
'route' => 'empty_if:url|route',
'parent_items'=> 'sometimes|required|integer'
]);
P.S. Don't forget to register this in your provider.
PS 不要忘记在您的提供商中注册它。

Add custom message
添加自定义消息
1) Add message 2) Add replacer
1) 添加消息 2) 添加替换器
Validator::replacer('empty_if', function($message, $attribute, $rule, $parameters){
$replace = [$attribute, $parameters[0]];
//message is: The field :attribute cannot be filled if :other is also filled
return str_replace([':attribute', ':other'], $replace, $message);
});

I think you are looking for required_if:
我认为您正在寻找required_if：
The field under validation must be present if the anotherfieldfield is equal to any value.
如果anotherfield字段等于任何值，则验证中的字段必须存在。
So, the validation rule would be:
因此，验证规则将是：
$this->validate($request, [
'name' => 'required|max:255',
'url' => 'required_if:route,""',
'route' => 'required_if:url,""',
'parent_items'=> 'sometimes|required|integer'
]);
