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.

@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.

Hi, unfortunately the integration in the core seems to take more years (that's how long it's been in planning). It would be great if the snippet would work again.
Many thanks for considering my request.
Many greetings
