我如何从我的购物车中的项目生成可下载的PDF文件？

Question

我使用的是 dompdf 生成一个可下载的pdf文件，从我的 multi-vendor eCommerce 我在QuotationController中定义了$cartItems，但还是遇到了这个错误。$cartItems是在CartController中定义的，我打算将CartController的项目获取到pdf中。

这就是错误所在。

Undefined variable: cartItems (View: C:\\laragon\www\procure\resources\views\cart\quote.blade.php)

这里是QuoteController代码。

<?php

namespace App\Http\Controllers;

use Barryvdh\DomPDF\PDF;
use Darryldecode\Cart\Cart;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;

class QuotationController extends Controller
{


    public function quote(Request $request)
    {

        $product = DB::table('products')->get();
        $cartItems = \Cart::session(auth()->id())->getContent();

        $pdf = \PDF::loadView('cart.quote');
        return $pdf->download('quotation.pdf');

        //return view('cart.quote');
    }

}

Herees is CartController:

<?php

namespace App\Http\Controllers;

use App\Product;
use Darryldecode\Cart\Cart;

class CartController extends Controller
{
    public function add(Product $product)
    {
        // add the product to cart
        \Cart::session(auth()->id())->add(array(
            'id' => $product->id,
            // 'img' => $product->cover_img,
            'name' => $product->name,
            'price' => $product->price,
            'quantity' => 1,
            'attributes' => array(),
            'associatedModel' => $product,
        ));

        return redirect()->route('cart.index');
    }

    public function index()
    {

        $cartItems = \Cart::session(auth()->id())->getContent();
        view()->share('cartItems', $cartItems);

        return view('cart.index', compact('cartItems'));
    }
    public function destroy($itemId)
    {

        \Cart::session(auth()->id())->remove($itemId);

        return back();
    }

    public function update($rowId)
    {

        \Cart::session(auth()->id())->update($rowId, [
            'quantity' => [
                'relative' => false,
                'value' => request('quantity'),
            ],
        ]);

        return back();
    }

    public function checkout()
    {
        return view('cart.checkout');
    }

}

最后是刀片文件(quote.blade.php)。
