Laravel multi-nested same route parameters - laravel

Question

I creating internet-marketn on Laravel 5.2
Need to do something like a breadcrumps in url with categories slug,
like so
/catalog/{category_1}/{category_2}/{category_n}
but get only last parameter and bind it into Model
moreover last category can has product slug and route can be like
/catalog/{category_1}/{category_2}/{category_n}/product/{product_slug}
my routing
Route::group(['prefix' => 'catalog'], function () {
Route::get('/', ['as' => 'shop_catalog', 'uses' => 'CatalogController#catalog']);
Route::group(['prefix' => '{category}'], function () {
Route::get('/', ['as' => 'shop_show_category', 'uses' => 'CategoryController#category']);
Route::group(['prefix' => 'product/{product}'], function () {
Route::get('/', ['as' => 'shop_show_product', 'uses' => 'ProductController#product']);
});
Try write pattern in RouteServiceProvider like
$route->pattern('category', '.*');
Then explode by '/' and get last element for binding. But can't get product parameter.
How can I do this logic?

The ordering of your routes is really important.
As the shop_show_category route is listed first, the router never gets to check if the url more specifically matches your shop_show_product route.
Route::group(['prefix' => '{category}'], function () {
Route::group(['prefix' => 'product/{product}'], function () {
Route::get('/', ['as' => 'shop_show_product', 'uses' => 'ProductController#product']);
});
Route::get('/', ['as' => 'shop_show_category', 'uses' => 'CategoryController#category']);
});
By rearranging so the more specific route is first, you know the router will check the shop_show_product route for a match first. Failing it seeing product/xxx at the end of the url it will try to match the shop_show_category route.
