I am trying to save data in these columns

Answer 1

One possibility is that, in the controller, $data is null. You can make the code fail by changing "find" to "findOrFail". The code will return a NotFoundException. Then you can investigate why $data is null.

Read https://laravel.com/docs/9.x/eloquent#not-found-exceptions .

Answer 2

the problem is probably in your update function it should be like this:

function update(Request $req){
$data = Member::find($req->id);

$data->Name = $req->Name;
$data->Email= $req->Email;
$data->Address = $req->Address;
$data->Phone = $req->Phone;
$data->save();

return redirect()->input();
}

in your update function you have changed the upper case to a lower case which will cause the Attempt to assign property "name" on null Error
