Question

I try to insert the session user id in form but it was show me error this:
SQLSTATE[HY000]: General error: 1364 Field 'user_id' doesn't have a default value (SQL: insert into stocks (product_name, product_code, details, price, cost, quntity, updated_at, created_at) values (basmati Rice, 23432, dskljsdlkks;lk; ;ks;lvk, 40, 75, 100kg, 2019-09-09 08:43:12, 2019-09-09 08:43:12))
I think error on this line of code which I used for store the session id
<input type="hidden" name="user_id"
value="{{ $request->session()->put('user',$request->input('id')) }}"
> class="form-control">

Answer 1

You don't have to use the $request->input('id') to get the user id .
Simply use
Session::flash(Auth::user()->id);
For your code ,
<input type="hidden" name="user_id"
value="{{Auth::user()->id, Session::flash(auth::user()->id) }}"
> class="form-control">
And in your controller ,
when you are trying to save the user_id variable ,
EDIT ::::
$stock = new Stock([
'user_id' => Auth::user()->id,
'product_name' => $request->get('product_name'),
'product_code' => $request->get('product_code'),
'details' => $request->get('details'),
'price' => $request->get('price'),
'cost' => $request->get('cost'),
'quntity' => $request->get('quntity')
]);
Use the session variable to store ,.
Or you can directly store the user_id using Auth::user()->id in that line ,
'user_id' => Auth::user()->user_id,

Answer 2

change this:
$request->session()->put('user',$request->input('id'))
to like this:
Session::set('user',$request->input('id'));
Make attention, you need pass the $request to your view, so you can use the request data. Otherwise create a variable $user_id and pass it to your view blade. in this case you can do:
Session::set('user',$user_id);
