Thanks for your reply – that’s been really helpful and I’ve pretty much got it working as I need to now. It was a nice surprise to find that the acf field data seems to be saved automatically without having to program manually. However, I don’t seem to be getting anything POSTed in the $_POST(‘acf’) array. I wondered if it was because I was running the free version (v4)? I have now upgraded to Pro (v5) and it still doesn’t seem to bring anything through. Is there an additional setting in acf_form() options that I have to set?
