抓住刀片中的ID号

Question

I have a route that takes me to my item page.

Route::get('/items/{item}', 'ItemsController@show');

In this page I have a form if the form is not filled out properly it will redirect to the forms method which currently is

action="/items"

How can I access that same {item} id number while in the blade?

Edit: Here is the Controller code

public function index()
{
  $item = Post::get();
  $price = $item->price;

  return view('item');
}

public function show(Item $item)
{
  return view('item', compact('item'));
}

Answer 1

You're returning compact('item') which gives you $item in your blade template.

You can use it within blade syntax, just like this:

{{ $item->id }}
