【问题描述】：

我在两个选项卡上有两个表单，我的问题是当我选择了第二个选项卡并发送我的表单时，如果它有一些错误，它会将我重定向回来，但在选项卡一个而不是两个，所以我创建了一个变量来控制加载时应在哪个选项卡中显示：

刀片文件：

<div class="tab-content" id="pills-tabContent">
    <div class="tab-pane fade  $tabName == 'yes' ? 'show active' : '' " id="pills-yes" role="tabpanel" aria-labelledby="pills-yes-tab">
        @include('secciones.formulario-contacto-reserva')
    </div>
    <div class="tab-pane fade  $tabName == 'no' ? 'show active' : '' " id="pills-no" role="tabpanel" aria-labelledby="pills-no-tab">
        @include('secciones.formulario-contacto-sin-reserva')
    </div>
</div>

当自定义请求中的验证失败时，我正在尝试将参数发送到我的视图：

ContactWithoutBookingRequest.php

<?php

namespace App\Http\Requests;

use Illuminate\Contracts\Validation\Validator;
use Illuminate\Validation\ValidationException;

use Illuminate\Foundation\Http\FormRequest;

class ContactWithoutBookingRequest extends FormRequest

    /**
     * Determine if the user is authorized to make this request.
     *
     * @return bool
     */
    public function authorize()
    
        return true;
    

    /**
     * Get the validation rules that apply to the request.
     *
     * @return array
     */
    public function rules()
    
        return [
            'inputNameSurname' => 'required|max:255',
            'inputEmail' => 'required|email|max:255',
            'selectMessage' => 'required|numeric|max:2',
            'inputComment' => 'required|max:3000|min:5',
            'privacityCheck' => 'required|boolean',
            'g-recaptcha-response' => 'required|captcha'       
        ];
    

我一直在尝试重写方法：failedValidation 和 getRedirectUrl，没有成功...

protected function getRedirectUrl()

    return redirect()->back()->with(['tabName' => 'no']);


protected function failedValidation(Validator $validator)

        throw (new ValidationException($validator))
                    ->errorBag($this->errorBag)
                    ->redirectTo(route('contacto'), ['tabName' => 'no']);

我怎样才能做到这一点？谢谢

【参考方案1】：

您可以在failedValidation 方法中将其刷入会话：

protected function failedValidation(Validator $validator)

    $this->session->flash('tabName', 'no');

    throw (new ValidationException($validator))
        ->errorBag($this->errorBag)
        ->redirectTo($this->getRedirectUrl());

然后在你的视图中从会话中检索它：

<div class="tab-content" id="pills-tabContent">
    <div class="tab-pane fade  Session::get('tabName') == 'yes' ? 'show active' : '' " id="pills-yes" role="tabpanel" aria-labelledby="pills-yes-tab">
        @include('secciones.formulario-contacto-reserva')
    </div>
    <div class="tab-pane fade  Session::get('tabName') == 'no' ? 'show active' : '' " id="pills-no" role="tabpanel" aria-labelledby="pills-no-tab">
        @include('secciones.formulario-contacto-sin-reserva')
    </div>
</div>

【讨论】：

完全忘记了所有通过重定向发送的都必须通过会话获取，非常感谢！

【参考方案2】：

试试这个方法：

return redirect(
    route('get.user.index', ['param' => $param])
)->with('success', 'Message if you need');

'get.user.index' - 是你的路线

['param' => $param] - 是您要放入路由的数组

【讨论】：

不工作它说 Class App\Http\Requests\ContactWithoutBookingRequest 不存在“如果我添加它
