Add second checkbox to checkout and segment by it?

Hi there,

I’m wondering if it’s possible to add a second checkbox to the WooCommerce checkout and pass information from that checkbox to a segment in my Mailchimp list?

What I would ideally like is two checkboxes, one that says “sign up to our mailing list” and one that says “share your information with our partners”.

The first checkbox will be the standard plugin checkbox that signs people up to the list. The second checkbox will add ‘true’ or ‘false’ to a list field I’ve created depending on whether it’s checked.

I’m *reasonably* familiar with php so if you have any developer documentation on this that you could point me to, I’d be hugely grateful.

Thanks!

Hannah
