我想将控制器中的变量传递给Laravel中的Blade文件。我的控制器中有两种不同的方法。视图中的变量来自两种不同的方法。一个变量输出取决于另一个。我希望将其保存为来自方法的第一个变量输出，当我传递另一个变量时，它将执行而不会出现未定义的变量错误。我如何在Laravel中做到这一点？
控制器
public function index2($id)
{
$categories1 = Category::find($id);
$products = $categories1->products->take(8);
$carousel = carousel::all();
$second_carousel = SecondCarousel::all();
$second_carousel2 = SecondCarousel::all();
$carousel1 = $second_carousel->first();
$carousel2 = $second_carousel->take(-4);
$categories = Category::all()->take(-3);
$category = Category::all()->first();
return view('onlineshop.index',
compact('carousel', 'carousel1', 'carousel2', 'categories', 'category', 'products'));
}
public function quickview($id)
{
$product_quickview = Product::find(1);
return view('onlineshop.index', compact('product_quickview'));
}

@isset($products)
@foreach($products as $product)
<li>
<figure>
<a class="aa-product-img" href="#">

第一步：创建新的刀片文件product_quiqe_view.blade.php
@isset($product_quickview)
<div class="col-md-6 col-sm-6 col-xs-12">
<div class="aa-product-view-content">
<h3>T-Shirt</h3>
<div class="aa-price-block">
<span class="aa-product-view-price">{{$product->price}}</span>
<p class="aa-product-avilability">Avilability: <span>In stock</span></p>
</div>
<p>

<h4>Size</h4>
<div class="aa-prod-view-size">
<a href="#">S</a>
<a href="#">M</a>
<a href="#">L</a>
<a href="#">XL</a>
</div>
<div class="aa-prod-quantity">
<form action="">
<select name="prod" id="prod">
<option value="0" selected>1</option>
<option value="1">2</option>
<option value="2">3</option>
<option value="3">4</option>
<option value="4">5</option>
<option value="5">6</option>
</select>
</form>
<p class="aa-prod-category">
Category: <a href="#">Polo T-Shirt</a>
</p>
</div>
<div class="aa-prod-view-bottom">
<a href="#" class="aa-add-to-cart-btn"><span class="fa fa-shopping-cart"></span>Add To Cart</a>
<a href="#" class="aa-add-to-cart-btn">View Details</a>
</div>
</div>
</div>
@endisset
Step2：将product_quiqe_view.blade.php文件包含在index.blade.php文件中，例如：
@isset($products)
@foreach($products as $product)
-------
@endforeach
@endisset
@include('product_quiqe_view');
第3步：在控制器中：
public function quickview($id)
{
$product_quickview = Product::find(1);
return view('onlineshop.product_quiqe_view',compact('product_quickview'))->render();
}
