Laravel：调用fail（）或pass（）方法后，无法向验证程序添加自定义错误

Question

在fails()上调用passes()或Validator方法后，我无法使用error validator添加after } hook

$validator = Validator::make(
    ['name' => 'kanav'],
    ['name' => 'required']
);

if($validator->fails()){...} // I've some code around this

if($somecondition) {
    $validator->after(function ($validator) {
        $validator->errors()->add('name', 'Name Invalid');
    });
}

dd($validator->errors()->first()); //returns ""
// dd($validator->fails()); // returns true

Answer 1

从doc开始，尝试在调用失败之前声明后挂钩，就像这样

$validator = Validator::make(
    ['name' => 'kanav'],
    ['name' => 'required']
);

if($somecondition) {
    $validator->after(function ($validator) {
        $validator->errors()->add('name', 'Name Invalid');
    });
}

if($validator->fails()){...}
