How to create a trigger to populate a table in database based on saved data in another table from laravel controller - sql

Question

I am creating an API with Laravel where I am trying to populate a table in a database based on saved data in another table in the database. So after table 1 data is saved, it should trigger for table 2 data to be also saved.
Here is the code for Controller of table 1
public function create(Request $request)
{
//
$this->validate($request, [
'name' => 'required|unique:users',
'code' => 'required'
]);
Auth::user();
$user = new User();
$user->inputed_code = $request->inputed_code;
$user->code = $request->code;
$user->save();
return response([
'success' => true,
'message' => 'Data has been saved!!',
'data' => $user,
], Response::HTTP_OK);
}
Here is the Controller for table 2 which I want to populate based on result from table 1 through a trigger effect.
public function reward(Request $request)
{
//
$reward = new Reward();
$reward->user_id = DB::table('users')->get(id)
$reward->points = $request->referral_reward;
$reward->save();
$user = $request->only('user_id');
$reward = Reward::where('user_id', '=', $user)->update([
'referral_reward' => 5
]);
return response()->json([
'success' => true,
'message' => 'You have been awarded 5 points',
'data' => $reward,
], Response::HTTP_CREATED);
}
Here are the API routes
Route::post('applycode', 'UserController#create');
Route::post('reward', 'RewardController#reward');
Please what am I doing wrong and is there is better way to approach this is give the same results.
Thank you

I understand that based on a saved User model you want to save something in your rewards table.
You could use Eloquent events. Register an event in your User model like this:
class User extends Model {
// ... other stuff
protected $dispatchesEvents = [
'saved' => UserSaved::class,
];
}
Then you need to create your events file by running php artisan make:event UserSaved, which creates a file app/Events/UserSaved.php. In this files __construct method you receive the affected model as parameter.
public function __construct(User $user)
{
// ... do sth
}
Then you need event listeners, see the docs, to consume the event
After defining and mapping your Eloquent events, you may use event listeners to handle the events.
Then inside the listener you can do all the logic you want to apply to your Rewards model.
