首先,先做一个简单的表单页面
<html>
    <head>
    </head>
    <body>
        <form action="/submit" method="post">
            <input type="text" name="a"></input>
            <input type="text" name="b"></input>
            <input type="text" name="c"></input>
            <input type="submit"></input>
        </form>
    </body>
<html>
编辑一条路由
Route::post('/submit','FormController@store');
创建一个控制器
<?php
namespace AppHttpControllers;
//use IlluminateHttpRequest;
use AppHttpRequests;
use Request;
class FormController extends Controller
{
  public function store(){
        //var_dump(Request::all());
        $input=Request::all();
        echo $input['a'].PHP_EOL;
        echo $input['b'].PHP_EOL;
        echo $input['c'].PHP_EOL;
    }
}
