Question

这是我的SubscriptionController代码：

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class SubscribersController extends Controller
{
    //




//This method is to process the form
public function postSubmit() {

  //we check if it's really an AJAX request
  if(Request::ajax()) {

    $validation = Validator::make(Input::all(), array(
      //email field should be required, should be in an email//format, and should be unique
      'email' => 'required|email|unique:subscribers,email'
    )
    );

    if($validation->fails()) {
      return $validation->errors()->first();
    } else {

      $create = Subscribers::create(array(
        'email' => Input::get('email')
      ));

      if($create){
        return Redirect::to('/')
                       ->with('success','You have been successfully subscribe to us.');

      }else{
        echo 'We could not save your address to oursystem, please try again later';
      }

    }

  } else {
    return Redirect::to('subscribers');
  }
}
}

这是我的Eloquent

代码

class CreateSubscribersTable extends Migration
{

    public function up()
    {
        Schema::table('subscribers', function (Blueprint $table) {
       $table->increments('id');
       $table->string('email,100)->default('');
       $table->timestamps();
        });
    }.....

在Route / web中：

Route::post('/subscribers', 'SubscribersController');

这是welcome.blade.php的代码

  <form action="/subscribers" method="post">

      <input type="email" name="email" placeholder="Email Address" required>

        <button type="button" class="btn btn-danger">Subscribe</button>

    </div>
  </form>

代码不要插入数据库中，也不要在控制台中显示任何错误。如果出现错误而没有任何内容我输入了postubmit函数回声。我已经搜索了一个教程而没有找到。我是Laravel的菜鸟。

Answer 1

在您的路线文件中，您的路线需要发送到某个操作，而不仅仅是控制器。

Route::post('/subscribers', 'SubscribersController');

应该是这个

Route::post('/subscribers', 'SubscribersController@postSubmit');

将csrf字段添加到html表单中：

<form action="/subscribers" method="post">
    {{ csrf_field() }}
    <input type="email" name="email" placeholder="Email Address" required>
    <button type="button" class="btn btn-danger">Subscribe</button>
</form>

Answer 2

路线应为Route::post('/subscribers','SubscribersController@postSubmit'); 并将csrf_field()添加到表单。

    <form action="/subscribers" method="post">
    {{csrf_field()}}
    <input type="email" name="email" placeholder="Email Address" required>
    <button type="button" class="btn btn-danger">Subscribe</button>
    </div>
   </form>`

Answer 3

首先，你跑了吗？

php artisan migrate

其次，正如霍林斯所说，你的路线：

Route::post('/subscribers', 'SubscribersController@postSubmit');

第三，在SubscribersController的顶部，添加：

use Subscribers;

除了让CreateSubscribersTable扩展Migration之外，还需要另一个名为Subscribers的模型类来扩展Model。您可能需要的所有课程：

SubscribersController extends Controller (you have it)

CreateSubscribersTable extends Migration (you have this too)

Subscribers extends Model/Eloquent (Do you have this?)

对不起，这就是我能想到的。将尝试检查更多以帮助。

或者如果你真的想知道问题出在哪里，可以尝试回复一些可能的问题＆＃34;测试＆＃34;，在你的每个内容中。

Answer 4

1）您的migration内容错误

public function up()
{
    Schema::create('subscribers', function (Blueprint $table) { //** 'create', not 'table'
        $table->increments('id');
        $table->string('email,100)->default('');
        $table->timestamps();
    });
}

删除您的数据库内容和php artisan migrate

2）您的表格是

<form action="/subscribers" method="post">
    {{ csrf_field() }}  //** add token
    <input type="email" name="email" placeholder="Email Address" required>
    <button type="submit" class="btn btn-danger">Subscribe</button> //** Button type : submit

</div>
</form>

您的路线：

Route::post('/subscribers', 'SubscribersController@postSubmit');

您的控制器

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Subscribers;        //********* change this

class SubscribersController extends Controller
{

    //This method is to process the form
    public function postSubmit(Request $request) {

        $validation = Validator::make($request->all(), [
            //email field should be required, should be in an email format, and should be unique

            'email' => 'required|email|unique:subscribers,email',
        ]);

        if($validation->fails()) {
            return $validation->errors()->first();
        }

        $create = Subscribers::create(array(
            'email' => $request->email,
        ));

        return Redirect::to('/')->with('success','You have been successfully subscribe to us.');

    }
}

将protected $table = 'subscribers';添加到您的Subscribers型号。

您为什么使用if (Request::ajax())？您没有通过AJAX提交表单。

如何使用Laravel存储来自Form in Database的值？
