Question

如何使用 Laravel 框架的 validator

Answer 1

参考：
<?php

namespace App\Http\Controllers;

use Validator;
use Illuminate\Http\Request;
use App\Http\Controllers\Controller;

class PostController extends Controller
{
/**
* Store a new blog post.
*
* @param Request $request
* @return Response
*/
public function store(Request $request)
{
$validator = Validator::make($request->all(), [
'title' => 'required|unique:posts|max:255',
'body' => 'required',
]);

if ($validator->fails()) {
return redirect('post/create')
->withErrors($validator)
->withInput();
}

// Store the blog post...
}
}
