Laravel 5.3 passing parameter from view to controller
提问by Angel Miladinov
I am making an online shop, so it has products. I am outputing all the products images and their names and I want when the user clicks on the product to redirect him to a single-product page the problem I have is passing the id of the product to the single-product view.
我正在做一个网上商店，所以它有产品。我正在输出所有产品图像及其名称，我希望当用户单击产品将他重定向到单一产品页面时，我遇到的问题是将产品的 id 传递给单一产品视图。
Here's my code Routing:
这是我的代码路由：
Route::get('single', [
"uses" => 'ProductsController@single',
"as" => 'single'
]);
Index.blade.php:
索引.blade.php：
<a href="{{ route('single', $product->product_id) }}" class="link-product-add-cart">See product</a>
And the controller:
和控制器：
public function single($product_id)
{
$product = Product::where('product_id', $product_id);
return view('single-product', compact("product"));
}

Make changes to your route as given below:
对您的路线进行如下更改：
Route::get('single/{product_id}', [
"uses" => 'ProductsController@single',
"as" => 'single'
]);
If you want to pass any parameters to your route then you've to assign placeholders for the parameters, so in your case, the {product_id}will be used as the placeholder which will be used to take the parameter from the URI, for example: http://example.com/single/1. So, you'll receive the 1as $product_idin your single method.
如果要将任何参数传递给路由，则必须为参数分配占位符，因此在您的情况下，{product_id}将用作占位符，用于从 中获取参数URI，例如：http://example.com/single/1。因此，您将在单一方法中收到1as $product_id。
