What is the php code for the live field value during input?
I mean, there has to be something because it can be used for conditional logic.
What I want to do is this:
I have a date value in an option page and if the user selects that specific date (during filling out the frontend form) I want to trigger an action….
T.i.a.
There is not PHP code running during input on the front end. Conditional logic is all handled by JavaScript. To do something like this you would need to add your own custom JS. https://www.advancedcustomfields.com/resources/adding-custom-javascript-fields/
