如何在会话Laravel中存储输入

Question

我是Laravel的新手在这里我试图将我的输入表单发布到会话中但是它不起作用我得到这个错误而没有任何消息:

Symfony \ Component \ HttpKernel \ Exception \ MethodNotAllowedHttpException

我一无所获,在这里我分享了一些代码.

我的控制器:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Category;
use \App\Product;

class ShopController extends Controller
{
    public function index()
    {
        $categories = Category::with('products')->get();
        return view('shop.index', compact('categories'));
    }

    public function category($id)
    {
        $products = Category::find($id)->products;
        return view('shop.1', compact('products'));
    }

    public function addToShoppingCart(Request $request)
    {
        $request->session()->put('cart', 'id');
        $request->session()->put('cart', 'number');

        $request->session()->flash('status', 'Product is toegevoegd!');
        return redirect()->back();
    }
}

我的看法:

@extends('layouts.app')

@section('content')
    @if(Session::has('id', 'number'))
        <div class="alert alert-success">
            {{Session::get('id', 'number')}}
        </div>
    @endif
    @foreach ($products as $product)
        <ul>
            <li>{{ $product->name }}</li>
            <li>{{ $product->description }}</li>
            <li>{{ $product->price }}</li>
            <li>{{ $product->amount }}</li>
        </ul>
        <form method="post" action="{{url('categories\{id}')}}">
            @csrf
            <div class="col-md-4">
                <label for="number">Aantal:</label>
                <input type="number" name="number">

                <label for="id">Id:</label>
                <input type="text" id="id" name="id" value= {{$product->id}}>

                <button type="submit" class="btn btn-success">Add product</button>
            </div>
        </form>
    @endforeach
    {{var_dump(Session::get('cart'))}}

@endsection

我的路线:

Route::get('/shop', 'Shopcontroller@index')->name('shop');
Route::get('/categories/{id}', 'ShopController@category');
Route::get('/cart/{id}', 'ShopController@addToShoppingCart');

我希望有人可以帮我解决我的问题,把输入放在laravel会话中.

您正尝试使用"获取"路线"发布".你应该改变Route::get通过Route::post
