fix double payments - double purchases - php

Question

i'm implementing an online payment platform similar to paypal, the problem is that when they click on the buy button 2 times or more quickly and this causes the payment to register twice instead of once
When you click buy execute this action:
public function invoke(Request $request) {
$payment_id = $request->get('payment_id');
$credenciales = config('services.mercadopago.token');
$request->get('user_id'));
$response = Http::get("https://api.mercadopago.com/v1/payments/$payment_id" . "?access_token=$credenciales");
$response = json_decode($response);
$request->session()->put('order', $response->order->id);
$request->session()->put('ingreso', $response->transaction_details->net_received_amount);
$request->session()->put('monto', $response->transaction_details->total_paid_amount);
$request->session()->put('method', $response->payment_type_id);
$status = $response->status;
If the answer is approved run this:
if($status == 'approved') {
Income::insert([
'user_id' => Session::get('user_id'),
'evento_id' => Session::get('variableName'),
//Guardar el personal seleccionado
'mp_id' => Session::get('order'),
'metodo' => Session::get('metodo'),
'monto' => Session::get('monto'),
'rrpp_id' => Session::get('rrpp'),
'ingreso' => Session::get('ingreso'),
]);
OrderNew::insert([
'user_id' => Session::get('user_id'),
'dia_id' => Session::get('variableName'),
//Guardar el personal seleccionado
'whatsapp' => Session::get('telefono'),
'cantidad' => Session::get('cantidad'),
'anticipada' => Session::get('anticipada'),
'horario' => Session::get('horario'),
'rrpp' => Session::get('rrpp'),
'pagado' => '1',
'tipo' => 'vip',
'codigo' => rand(1580, 4005),
]);
in the first model I register the incoming money and in the second model I register the customer's order
and there is the problem, if they click on Buy several times, the records are duplicated and they get free products
How can I limit or solve this problem?

Answer 1

Instead of Insert use updateOrCreate or maybe firstOrCreate that accepts 2 parameters, first one an array to check the values against database records and second to insert/find data. If the records match, it will be updated/retrieved, otherwise a new one will be created. Please check Laravel docs for updateOrCreate or firstOrCreate.
In your case, for example:
Income::firstOrCreate([
'user_id' => Session::get('user_id'),
'evento_id' => Session::get('variableName'),
//Guardar el personal seleccionado
'mp_id' => Session::get('order'),
'metodo' => Session::get('metodo'),
'monto' => Session::get('monto'),
'rrpp_id' => Session::get('rrpp'),
'ingreso' => Session::get('ingreso'),
]);
This will check the exact records and if it finds a match it retrieves the data, otherwise creates one which avoids duplicated entries.
However, since your second query has a random number generated, it will not find a match if we pass only one arguement, therefore, as a first arguement we need to pass the array to be checked against the database (all data, except for the rand() part).
OrderNew::firstOrCreate(
[
'user_id' => Session::get('user_id'),
'dia_id' => Session::get('variableName'),
//Guardar el personal seleccionado
'whatsapp' => Session::get('telefono'),
'cantidad' => Session::get('cantidad'),
'anticipada' => Session::get('anticipada'),
'horario' => Session::get('horario'),
'rrpp' => Session::get('rrpp'),
'pagado' => '1',
'tipo' => 'vip',
],
[
'user_id' => Session::get('user_id'),
'dia_id' => Session::get('variableName'),
//Guardar el personal seleccionado
'whatsapp' => Session::get('telefono'),
'cantidad' => Session::get('cantidad'),
'anticipada' => Session::get('anticipada'),
'horario' => Session::get('horario'),
'rrpp' => Session::get('rrpp'),
'pagado' => '1',
'tipo' => 'vip',
'codigo' => rand(1580, 4005),
]);
According to your data, you can change the array of data to be checked against the database.

Answer 2

Specify that the route should not allow concurrent requests from the same session.
Route::get('/deposit',ExampleController::class)->block(10);
