Question

有没有办法在laravel中抛出手动表单验证错误。我们说有一个功能可以检查信用卡的号码，如果失败，我想设置一个错误并将用户重定向回到表单。我正在找类似的东西。

在Laravel中实际上有很多方法可以验证。

来自Controller

＆＃13;

Validator::make($request->all(), [
        'ccv' => 'required|numeric|max:3',
        'card_number' => 'required',
     'expiry_date' => 'required',
 ])->validate();

＆＃13;

在代码中明确指定要将请求重定向到哪里

＆＃13;

 $validator = Validator::make($request->all(), [
            'ccv' => 'required|numeric',
            'card_number' => 'required',
             'expiry_date' => 'required',

            
        ]);

        if ($validator->fails()) {
            return redirect('pay/with/creditcard')
                        ->withErrors($validator)
                        ->withInput();
        }

＆＃13;

在第一次验证后再做一次验证，例如（检查卡是否可以扣除）

＆＃13;

$validator = Validator::make(
                'ccv' => 'required|numeric',
                'card_number' => 'required',
                 'expiry_date' => 'required',); //your normal validation here. e.g  ccv, required fields etc.
    
    $validator->after(function ($validator) {
        if (!$this->validateCreditCard()) { //do another validation e.g check if card is debitable
        
            $validator->errors()->add('credit_card', 'Something is wrong with this credit card!');
        }
    });

＆＃13;

您可以重定向回付款表单。我们假设您的路线是＆＃39; pay/with/creditcard＆＃39;

if ($validator->fails()) {
            return redirect('pay/with/creditcard')
                        ->withErrors($validator)
                        ->withInput();
        }
