Isso deve levá-lo muito longe. Ele não foi testado completamente, portanto, leia o código, entenda-o e faça as alterações apropriadas para que funcione.
Eu removi a
function e inline todo o código no loop, a função era muito volumosa para o meu gosto. Agora você deve ser capaz de ver mais claramente o que está acontecendo. Efetivamente, é exatamente o mesmo código duas vezes, com uma pequena etapa extra que adiciona auto-referências para que você possa consultar todos os produtos por meio de seu ID primário e de seus IDs secundários da mesma maneira, conforme discutido nos comentários.
