Redirect Paid Memberships Pro Confirmation to Another Page Based on Level

my_pmpro_confirmation_redirect.php

/*
	This code will redirect users from the default PMPro confirmation page to a specific page depending on their level.
	Set the confirmation_pages array. Array keys should be membership level ids and the values are the page ids. So array(1=>2) will redirect membership level with id = 1 to the page with id = 2.

Where would one put this code...many of the other Gist's advise where to place.....

Same place. Put it in your active theme's functions.php or a custom plugin. Search for pmpro-customization for how to create a custom plugin.

How do you do this for more than one membership level? Do you just paste the code again and change the numbers to a new page ID and membership level?
