将param {id}粘贴到路径Laravel的控制器中

Question

I have a route:

Route::get('/{id?}/{post}', 'PostController@show')->name('postshow');

I can paste param {id} from controller?

public function showPost($id = null, Post $post)
{
    $id = $post->id;
    return view('post.show', compact('post'));
}

I need when user go to post, I need url of post will be: http://example.com/12345/post-slug

Now I get: http://example.com/post-slug

I know that I can pass id in route: route('postshow', [$post->id, $post]); But I can't, because in blade I have 1000+ records like this: route('postshow', $post); And search and edit every blade file I can't.

As per your below route :

Route::get('/{id?}/{slug}', 'PostController@show')->name('postshow');

And in the controller(not sure how you want it but as per my understanding of your question :

public function showPost($id = null, $slug)
{
    if($id){
        $post = Post::findOrFail($id);
    }
    else{
        $post = Post::where('slug', $slug)->firstOrFail();
    }

    return view('post.show', compact('post'));
}

In blade, if you want to generate this url :

route('postshow', [ 'id' => $post->id, , 'slug' => $post->slug]);
