We did it but not recently.

You need to submit a letter from the sponsor addressed to immigration, for both spouses if both spouses work.

You'll need photocopies including residence permit for all family members including kids.
Copy of marriage contract.

Then you submit the application for a maid/nanny visa at immigration (get the from them) and include above documents.

If they reject the appilcation first-time resubmit. They often reject it first-time. Once you have the approval from the emplyment visa committee you can apply for the lady's visa.

Once you have the visa you go to the Philippines Embassy. They don't like doing it but if you're nice they'll help you with the formalities. They prefer to deal with the agencies. They'll draw up a contract which you have to sign, then transfer it to their labor office who approve it. You can then send that to Manila where your maid/nanny has to register it with the labor department. She should've undergone a medical there by that time.

Then send her the PTA.
