@searchenginepro We're seriously considering pursuing this as part of the Gravity Perks suite but I'm not sure that would help you as our lowest tier is $59/year, only $3 less than with the existing dev is charging. 😕
Better late than never :) @spivurno
@searchenginepro
I just put together a standalone plugin that does exactly what you're describing: grouped AND/OR conditional logic for fields, buttons, confirmations, and notifications. It's available here for testing: https://github.com/guilamu/gf-ifonly
That said, whatever GF-IfOnly turns out to be, it will never come anywhere close to what @spivurno and his team would build. I've been a very happy Gravity Perks user for over a decade, and I genuinely mean it when I say that nobody in the WordPress community comes even remotely close to their level of craftsmanship, their depth of GF expertise, or their exceptionally stellar support. This is just a community stopgap — the real thing will come from them.
@bsmaha
Hey @bsmaha — just a friendly nudge: this is an open-source proof-of-concept sitting on a public Gist. If you'd like to see it move faster, the most effective thing you can do is roll up your sleeves and contribute — open a PR, file a detailed issue, or even just test and document what's broken. Waiting around for someone else to do it on their own time isn't really a strategy. The community moves at the speed of the people willing to put in the work.

Any updates on this for 2026? I really need advanced conditional logic, but the one developer in Germany that created a plugin has priced it beyond what I can justify currently.
