Get old input via old() in laravel 5.5 not working

Question

This is my controller. I am trying to validate the form and show error messages if any. The form is validating fine but when it redirects back to the form if validation fails, then old form values are not working

<?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);
        }
    }

}

Here is the contact-form.blade.php where error messages are displaying errors correctly as expected but old values are not displayed

@extends('layout.front')
@section('content')

How to resolve the mistake?

Answer 1

将输入添加到您的重定向中：

return redirect()->back()->withInput($request->all())->withErrors($validation);

Answer 2

使用back()代替redirect()->back()作为

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