Answer 1

Try this in your controller
public function update(Request $request, $id)
{
$validated_data = $request->validate([
'name' => 'required|max:255', (add all the form here)
]);
YourModel::where('id', $id)->update($validated_data);
return redirect('admin/problem')->with('success', 'Data berhasil diubah');
}
Tips* dump all the request with dd($request->all) so you can see all of your input form data
