Cannot get id of subscription in request - laravel

Question

I'm trying to get the id of the selected subscription and pass it to the controller, but for some reason when I dd() or print_r() the id in the controller, it returns the same id regardless of which subscription I click.
Regardless if i click the first '+' button or the second one it always returns the same id when I print_r() it.
Array ( [_token] => iFimNDCv0q4rq7OmmUWGN8SGr2Bq0brsiRMLIzBD [subscription] => 2 )
Even when I click the first one, which should have '1' as the id, it still returns '2'.
This is my route for it in web.php
Route::post('/transaction/store', 'TransactionController#store')->name('transaction.store');
This is the function in the controller
public function store(Request $request)
{
// continue here
print_r($request->input());
}
And this is the form tag that's responsible for send the id (which is inside a foreach statement in blade)
<form id="batch" action="{{route('transaction.store')}}" method="POST">
#csrf
<input type="hidden" name="subscription" value="{{$subscription->id}}" form="batch">
<button type="submit" class="btn btn-sm btn-outline-dark" form="batch">+</button>
</form>
Thanks very much for any help!

Answer 1

I just had to make the form id dynamic!
<form id="batch-{{$subscription->id}}" action="{{route('transaction.store')}}" method="POST">
#csrf
<input type="hidden" name="subscription" value="{{$subscription->id}}" form="batch-{{$subscription->id}}">
<button type="submit" class="btn btn-sm btn-outline-dark" form="batch-{{$subscription->id}}">+</button>
</form>
