Question

我创建了一个表单，我正在尝试提交数据，但错误：

MethodNotAllowedHttpException in RouteCollection.php line 218:

即将到来。怎么办？

欢迎光临：

@extends('layouts.master')

@section('title')
Welcome!!
@endsection

@section('content')
@include('includes.message-block')
<div class="row">
    <div class="col-md-6">
        <h2>Enter Your Information</h2>
          <form action="" method="post">    
            <div class="form-group" {{$errors -> has('name') ? 'has-error': ''}}>
                <label for="name">Name</label>
                <input class="form-control" type="text" name="name" id="name" placeholder="Your name">

            <div class="form-group" {{$errors -> has('email') ? 'has-error': ''}}>

            </div>  
            <div class="form-group">
                <label for="course_name">Course Name</label>
                <input class="form-control" type="text" name="course_name" id="course_name" placeholder="Enter Your Course">
            </div>
            <button type="submit" class="btn btn-primary">Submit</button>
            <input type="hidden" name="_token" value="{{Session::token()}}">                
        </form>

型号：

<?php

namespace App;
use Illuminate\Contracts\Auth\Authenticatable;
use Illuminate\Database\Eloquent\Model;


class User extends Model implements Authenticatable
{
use \Illuminate\Auth\Authenticatable;
protected $table = 'students';

}

UserController中：

<?php

namespace App\Http\Controllers;
use Illuminate\Support\Facades\Input;
//use Illuminate\Support\Facades\Flash;
use InvalidConfirmationCodeException;
use Flash;
//use Mail;
use App\User;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use Illuminate\Foundation\Auth\AuthenticatesAndRegistersstudents;

class UserController extends Controller

{

 public function postData(Request $request)
 {
    $this -> validate($request,[
      'email' => 'required|email|unique:students',
      'name'  => 'required|max:20',
      'branch'  => 'required|max:10'
      'course_name'  => 'required|max:10'
      ]);

    $email = $request['email'];
    $name = $request['name'];
    $branch = $request['branch'];
    $course_name = $request['course_name'];



    $student = new User();
    $student->email =$email;
    $student->name = $name;
    $student->branch = $branch;
    $student->course_name = $course_name;


    $student->save();

    return redirect()->back();

 }
}

路线/ web.php：

Route::group(['middleware' => ['web']], function(){
Route::get('/', function () {
    return view('welcome');
});

Route::post('/submit_data',[
    'uses' => 'UserController@postData',
    'as' => 'submit_data'
    ]);
});

迁移：

<?php

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateUsersTable extends Migration
{

public function up()
{
    Schema::create('students', function (Blueprint $table) {
        $table->increments('id');
        $table->string('mail')->unique();
        $table -> string('name');
        $table -> string('branch');
        $table -> string('course_name');
        $table->rememberToken();
        $table->timestamps();
    });
}


public function down()
{
    Schema::drop('students');
}
}

我的迁移名称是create_users_table。我不明白为什么会出现这个错误。这是一个简单易用的表单。只需一个简单的表单即可提交学生数据，并将其保存在数据库中。

Answer 1

您要发布到get路径

在welcome.blade.php您忘记设置action，因此默认情况下，它会尝试发布到同一页/，该页面被定义为get路由你的routes/web.php。在/submit_data：

中将操作设置为welcome.blade.php

<form action="{{ url('/submit_data') }}" method="post">

Answer 2

<form action="{{ url('submit_data') }}" method="post">

Answer 3

你也可以像这样使用刀片

{{Form::open(array('url'=>'/submit_data','files'=>true,'class'=>'form-horizontal','file'=>'true'))}}
