Laravel 7.x Creating default object from empty value

Question

I'm trying to make a 'edit' page for a 'bookshop'. Everything in the front-end seems perfect, but when I click edit after inputting data I get this error: "Creating default object from empty value"

I've tried adding a 'new' as I seen on other topics but it didnt help.

My controller:

function Update(Request $request){

    $entry = Book::find($request->route('id'));
    $entry->name = $request -> book_name;
    $entry->writer_name = $request->writer_name;
    $entry->isbn = $request->book_isbn;
    $entry->save();
    return redirect('/');
}

It gives error on this line

$entry->name = $request -> book_name;

My router for update

Route::post('/edit/update/{id}','EditController@Update');

My form

<form  method="POST" action="/edit/update/{id}">

It is just a basic form that updates the database items. When I click 'edit' (button) after changing some values it gives me the 'Creating default object from empty value' error.

$request -> book_name;

should be

$request->book_name;

(without spaces)

I would also recommend using

$entry = Book::findOrFail($id);

in case the id is not found. Also, I guess what you mean is:

function update(Request $request, $id){
    $entry = Book::findOrFail($id); 
}

Now I get another error... The POST method is not supported for this route. Supported methods: GET, HEAD.:( I'm literally tired of errors

be sure to add the {{ csrf_field() }} inside your <form>, if not you will get a CSRF error.
