Php 如何在不登录的情况下添加到购物车或愿望列表

我想将产品添加到购物车中，但为此我想登录用户。这意味着在用户登录后，只有他才能看到自己的购物车。但登录后，如果他看到购物车，他应该会看到他刚刚添加到购物车的产品，但他看到的是旧的。虽然我将url放在controller的会话中。我如何使其正确

这里是显示登录表单：

     public function showLoginForm()
        {
            Session::put('url.intended',\URL::previous());
            return view('cart.login');
        }

public function addCart(Request $request)
    {
        if(Auth::check())
        {
        $name = $request->name; 
        $product = Product::where('name' , '=', $name)->first();
        $product_id = $product->id;
        $product = DB::table('carts')           
                ->where('carts.product_id','=',$product_id)
                ->where('carts.status','=',1)
                ->select('carts.product_id')
                ->first();

        if(!$product){
            $cart = new Cart(); 
            $checkBox = Input::get('additionals');
            if (is_array($checkBox)){
            $cart->additionals = array_sum($checkBox);
        }
        else {
            $cart->additionals =0;
        }
            $cart->user_id =Auth::user()->id;
            $name = $request->name; 
            $product = Product::where('name' , '=', $name)->first();
            $cart->product_id = $product->id;
//          $product = Product::find($cart->product_id);
            $cart->price =$product->price;  
            $cart->status = 1;  
            $cart->save();
            return redirect('shop-cart');           
        }
        else {          
            return redirect('shop-cart');
            }
        }

        else{
            return redirect('/login');
        }
    }

protected function login(Request $request)
    {
        $this->validate($request, [
            'email' => 'required|email',
            'password' => 'required',
        ]);

        if (auth()->attempt(array('email' => $request->input('email'),
             'password' => $request->input('password'))))
        {
            if(auth()->user()->is_activated == '0'){
                 Auth::logout();
                return back()->with('warning',"First please active your account.");
            }

            else{
                return Redirect::to(Session::get('url.intended'));

            }


        }
        else{
            return back()->with('error','your username and password are wrong.');
        }
    }

 Route::get('add-to-cart/{name}','CartController@addCart');

添加到购物车控制器：

     public function showLoginForm()
        {
            Session::put('url.intended',\URL::previous());
            return view('cart.login');
        }

public function addCart(Request $request)
    {
        if(Auth::check())
        {
        $name = $request->name; 
        $product = Product::where('name' , '=', $name)->first();
        $product_id = $product->id;
        $product = DB::table('carts')           
                ->where('carts.product_id','=',$product_id)
                ->where('carts.status','=',1)
                ->select('carts.product_id')
                ->first();

        if(!$product){
            $cart = new Cart(); 
            $checkBox = Input::get('additionals');
            if (is_array($checkBox)){
            $cart->additionals = array_sum($checkBox);
        }
        else {
            $cart->additionals =0;
        }
            $cart->user_id =Auth::user()->id;
            $name = $request->name; 
            $product = Product::where('name' , '=', $name)->first();
            $cart->product_id = $product->id;
//          $product = Product::find($cart->product_id);
            $cart->price =$product->price;  
            $cart->status = 1;  
            $cart->save();
            return redirect('shop-cart');           
        }
        else {          
            return redirect('shop-cart');
            }
        }

        else{
            return redirect('/login');
        }
    }

protected function login(Request $request)
    {
        $this->validate($request, [
            'email' => 'required|email',
            'password' => 'required',
        ]);

        if (auth()->attempt(array('email' => $request->input('email'),
             'password' => $request->input('password'))))
        {
            if(auth()->user()->is_activated == '0'){
                 Auth::logout();
                return back()->with('warning',"First please active your account.");
            }

            else{
                return Redirect::to(Session::get('url.intended'));

            }


        }
        else{
            return back()->with('error','your username and password are wrong.');
        }
    }

 Route::get('add-to-cart/{name}','CartController@addCart');

和登录控制器：

     public function showLoginForm()
        {
            Session::put('url.intended',\URL::previous());
            return view('cart.login');
        }

public function addCart(Request $request)
    {
        if(Auth::check())
        {
        $name = $request->name; 
        $product = Product::where('name' , '=', $name)->first();
        $product_id = $product->id;
        $product = DB::table('carts')           
                ->where('carts.product_id','=',$product_id)
                ->where('carts.status','=',1)
                ->select('carts.product_id')
                ->first();

        if(!$product){
            $cart = new Cart(); 
            $checkBox = Input::get('additionals');
            if (is_array($checkBox)){
            $cart->additionals = array_sum($checkBox);
        }
        else {
            $cart->additionals =0;
        }
            $cart->user_id =Auth::user()->id;
            $name = $request->name; 
            $product = Product::where('name' , '=', $name)->first();
            $cart->product_id = $product->id;
//          $product = Product::find($cart->product_id);
            $cart->price =$product->price;  
            $cart->status = 1;  
            $cart->save();
            return redirect('shop-cart');           
        }
        else {          
            return redirect('shop-cart');
            }
        }

        else{
            return redirect('/login');
        }
    }

protected function login(Request $request)
    {
        $this->validate($request, [
            'email' => 'required|email',
            'password' => 'required',
        ]);

        if (auth()->attempt(array('email' => $request->input('email'),
             'password' => $request->input('password'))))
        {
            if(auth()->user()->is_activated == '0'){
                 Auth::logout();
                return back()->with('warning',"First please active your account.");
            }

            else{
                return Redirect::to(Session::get('url.intended'));

            }


        }
        else{
            return back()->with('error','your username and password are wrong.');
        }
    }

 Route::get('add-to-cart/{name}','CartController@addCart');

添加到购物车路线：

     public function showLoginForm()
        {
            Session::put('url.intended',\URL::previous());
            return view('cart.login');
        }

    {
        if(Auth::check())

            $cart->price =$product->price;  
            $cart->status = 1;
