Laravel 验证不起作用

Question

I am taking a laravel course an in order to follow the course I have to fix this issue, I checked everything, and apparently, everything is the same as the guy shows me. But the difference is that his validation works but not mine. It has to redirect me to the register_form when the validation is invalid but it doesn't.

Route

Route::get('/', function(){
    return view('welcome');
});

Route::get('/register', 'HomeController@register_form');

Route::post('/register', 'HomeController@register');

Controller

namespace CoolBlog\Http\Controllers;

use Illuminate\Http\Request;

class HomeController extends Controller {

    public function register_form(){
        return view('register');
    }

    public function register(Request $request) {
        $this->validate($request, [
            'username' => 'min:5|max:30',
            'email' => 'email',
            'pass' => 'min:5',
            'pass2' => 'same:pass'
        ]);
    }
}

Html Page

@extends('layout.default')

@section('title', 'Registration')

@section('content')
    <form method="post" action="/register" >
        {{csrf_field()}}
        Name: <input type="text" name="username"><br>
        E-mail: <input type="text" name="email"><br>
        Password: <input type="password" name="pass2"><br>
        Re-Password: <input type="password" name="pass2"><br>
        <input type="submit" value="Register">
    </form>

@endsection

Answer 1

Change this line:

Password: <input type="password" name="pass2"><br>
Re-Password: <input type="password" name="pass2"><br>

and replace it with this:

Password: <input type="password" name="pass"><br>
Re-Password: <input type="password" name="pass2"><br>

and in your validation if you want any field must be required then add required in the validation

$this->validate($request, [
            'username' => 'required|min:5|max:30',
            'email' => 'required|email',
            'pass' => 'required|min:5',
            'pass2' => 'required|same:pass'
        ]);

Answer 2

You are using same name for password and password confirmation. Change password name to pass in your blade file and try using this validation instead

$this->validate($request, [
        'username' => 'required|min:5|max:30',
        'email' => 'required|max:255|unique:users',
        'pass' => 'required|min:6|confirmed'
    ]);

I saw that you are not returning to any route after validating the form values. So, can you please try this code format. the validation method is also updated on upper level laravel versions

function store(Request $request)
    {
        request()->validate([
            'title' => 'required',
            'body' => 'required',
        ]);
        Post::create($request->all());
        return redirect()->route('posts.index')->with('success', 'Post created successfully');
