Question

这是我的控制器。我试图验证表单并显示错误消息，如果有的话。表单验证正常，但如果验证失败则重定向回表单，那么旧表单值不起作用

<?php

namespace App\Http\Controllers\Frontend;

use App\Http\Controllers\Frontend\AbstractController as FrontendController;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Validator;



class ContactFormController extends FrontendController
{
    protected $validationRules = [
        'Name'      => 'required',
        'email-360' => 'required|email',
        'telephone' => 'required',
        'Bio'       => 'required',
    ];

    public function index(Request $request)
    {
        $request->flash();
        $viewData = [
            'meta_title'       => _('Contact Us'),
            'meta_description' => _(''),
        ];
        return view('frontend.contact-form', $viewData);
    }

    public function saveContactForm(Request $request)
    {
        $validationMessages = [
            'Name.required' => _('This field is required.'),
            'email-360.required' => _('This field is required.'),
            'telephone.required' => _('This field is required.'),
            'Bio.required' => _('This field is required.'),
        ];

        $request->flash();
        $validation = Validator::make($request->all(), $this->validationRules, $validationMessages);
        if ($validation->fails()) {
            return redirect()->back()->withInput()->withErrors($validation);
        }
    }

}

这是contact-form.blade.php，其中错误消息按预期正确显示错误但未显示旧值

如何解决错误？

Answer 1

将输入添加到重定向：

ggplot(NDVIdfmean_forplot[order(NDVIdfmean_forplot$image),], aes(x=image, y=value, group=ID)) + geom_line() +
  geom_path()

Answer 2

使用back()代替redirect()->back()作为

return back()->withInput()->withErrors($validation);

通过laravel 5.5中的old（）获取旧输入不起作用
