error

Answer 1

Instead of doing $data->status=$request->$data->status; do $data->status = $request->status;

$request does not have the data from the model, which is in the $data variable.

Answer 2

Try this:

<select class="form-select" aria-label="Default select example" name="status">

And also in your controller you have to change:-

$data = Invoice::find($invoice_id);
$data->status = $request->status;
$data->save();

Hope this will work for you.

Answer 3

Hi first of all you need to async you select tag with name tag and set it to status for example

<select class="form-select" aria-label="Default select example" name="status">
<input type="hidden" value="{{ $inv->id }}" name="inv_id"/>

then in your controller first of all you need to validate your request incomping data for mor information please see this in laravel documentations

after that you need to change your code like this

$data= Invoice::find($request->inv_id);
$data->status= $data->status;
