Question

我有一个查看我的单品的show.php，当用户点击ADD PRODUCT我的控制器CartController.php更新我的会话购物车并更新我的cartSession表，现在我尝试在我的会话和我的CartSession表中添加新数据（颜色输入，大小输入，数量输入）。但我不知道为什么它不起作用。

- 我认为主要问题是$ request-＆gt; get（＆＃39;输入＆＃39;）没有传递给我的CartController.php，我试图返回 $ request-＆gt; all（）并没有什么。

CartController.php

namespace dixard\Http\Controllers;

use Illuminate\Http\Request;

use dixard\Http\Requests;
use dixard\Http\Controllers\Controller;

use dixard\Product;
use dixard\CartSession;
use dixard\CartItem;
use dixard\Shipping;
use Session; 

// i think that all classes are ok

public function add(Product $product, CartSession $CartSession,Request $request)
{
    $id = $request->get('id');
    $cart  = \Session::get('cart'); 

    $product->quantity = $request->get('qty');
    $product->size = $request->get('size');
    $product->color = $request->get('color');
    $cart[$product->id] = $product; 

    \Session::put('cart', $cart); 

    return $request->all(); // here i tried to get all inputs but it shows me nothing result
    $subtotal = 0;

    foreach($cart as $producto){
        $subtotal += $producto->quantity * $producto->price;
    }   

    $session_code = Session::getId();
    $CartSession = new CartSession();

    $session_exist = CartSession::where('session_code', $session_code)->orderBy('id', 'desc')->first();

    if (isset($session_exist)) {


            $s = new CartSession;

            $data = array(

            'subtotal' => $subtotal,

            );

            $s->where('session_code', '=', $session_code)->update($data);


    }else {

            $CartSession = new CartSession();
            $CartSession->session_code = $session_code; 
            $CartSession->subtotal = $subtotal; 
            $CartSession->save(); 
    }

    //return $cart;
    //salveremo tutte le informazioni nel array cart nella posizione slug

    foreach($cart as $producto){
        $this->saveCartItem($producto, $CartSession->id, $session_code, $cart);
    }

    return redirect()->route('cart-show');


}

routes.php文件

Route::bind('product', function($id) {
     return dixard\Product::where('id', $id)->first();
    });

     Route::get('cart/add/{product}', [

            'as' => 'cart-add',
            'uses' => 'CartController@add'

            ]);

show.php视图

获取有关该产品的数据是否正常，标题，描述，颜色可用，价格ecc。所有信息都传递给我。

{!! Form::open(['route'=> ['cart-add', $product->id],'class'=>'form-horizontal form-label-left'])!!}

                <input type="hidden" name="_method" value="PUT">

感谢您的帮助！

Answer 1

你必须明确地将post-method设置为＆＃34; get＆＃34;或者您需要更改路由器以接收请求作为发布。即使您按名称调用路由，Form :: open默认为＆＃34; POST＆＃34;

https://laravelcollective.com/docs/5.2/html#opening-a-form

选项1.更改

Route::get('cart/add/{product}',...

到

Route::post('cart/add/{product}',...

选项2.更改

{!! Form::open(['route'=> ['cart-add', $product->id],'class'=>'form-horizontal form-label-left'])!!}

到

{!! Form::open(['method'=>'GET', 'route'=> ['cart-add', $product->id],'class'=>'form-horizontal form-label-left'])!!}
