表单标记

Question

我是Laravel的新手，并使用laravel购物车library和Laravelcollective创建了一个ecomm网站。我目前停留在单个删除按钮上的Symfony \ Component \ HttpKernel \ Exception \ MethodNotAllowedHttpException但是如果我们创建另一个删除按钮，则第二个按钮可以正常使用相同的代码，而第一个按钮会创建错误。请帮我解决这个错误。

我的错误是： 我的路线文件是：

    <?php

    /*
    |--------------------------------------------------------------------------
    | Web Routes
    |--------------------------------------------------------------------------
    |
    | Here is where you can register web routes for your application. These
    | routes are loaded by the RouteServiceProvider within a group which
    | contains the "web" middleware group. Now create something great!
    |
    */

    Route::get('/','FrontController@index')->name('index');
    Route::get('shop', 'FrontController@shop')->name('shop');
    Route::get('details', 'FrontController@details')->name('productdetails');
    Route::get('/logout', 'Auth\LoginController@logout');
    Auth::routes();

    Route::get('/home', 'HomeController@index')->name('home');
    Route::resource('/cart','CartController');

    Route::group(['prefix' => 'admin', 'middleware' => 'auth'], function () {
        Route::get('/', 'AdminController@index')->name('admin.index');
        Route::resource('product','ProductsController');
        Route::resource('category','CategoriesController');
    });

我的错误创建页面为here。

顶部的表单标记创建错误，底部的表单标记正常工作。

我的控制器是：

<?php

namespace App\Http\Controllers;

use Gloudemans\Shoppingcart\Facades\Cart;
use App\Product;
use Illuminate\Http\Request;

class CartController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $products=Product::orderBy('id','DESC')->take(4)->get();
        $cartItems = Cart::content();
        return view('cart.index',compact('products','cartItems'));
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {

    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        //
    }

    /**
     * Display the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function show($id)
    {
        //
    }

    /**
     * Show the form for editing the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function edit($id)
    {
        $product = Product::find($id);
        Cart::add($id,$product->name,1,$product->price);
        return back();
    }


    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, $id)
    {
        Cart::update($id,$request->qty);
        return back();
    }

    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function destroy($id)
    {
        Cart::remove($id);
        return back();
    }
}

我只希望顶层表单标记起作用。请指导我。感谢

Answer 1

因为您正在为购物车使用资源控制器。所以你应该使用delete方法删除按钮。

<form action="{{route('cart.destroy',$cartItem->rowId)}}">
    {{ method_field('DELETE') }}
    {{ csrf_field() }}
    <button>Delete</button>
</form>

Answer 2

您可以尝试

Route::resource('/cart','CartController')->name('cart');
