如何在laravel中的闭包函数中调用laravel验证规则？

Question

I wish to skip the captcha validation if the account,which maybe a email or mobile, has been captcha validated.

so I write a colsure function. if the session('captcha_validated_reset_account') equals to the account which user input, it will skip the captcha validation.

if not, the program will call a laravel validation rule like "required|captcha"(captcha' comes from https://github.com/mewebstudio/captcha).

The problem is I don't know how to call validation rule in a closure,I tried return 'required|captcha' but it not work as intended.

'captcha' => function($attribute, $val, $fail)use($request) {
            if(!empty(session('captcha_validated_reset_account'))&&session('captcha_validated_reset_account')==$request->input('account')){
                return;
            }else{
                Rule::required... //and call a rule named 'captcha' to validate the captcha code from user input
                //return 'required|captcha';
            }
        }

Is any way I can call laravel validation rules in a closure function?

You should put the closure in an array:

'captcha' => [ function($attribute, $val, $fail) use($request) {
            if(empty(session('captcha_validated_reset_account'))
               && session('captcha_validated_reset_account') != $request->input('account')){
                $fail($attribute . ' is required.');
            }
        }]

Note that I've changed the condition.
