Possible to Use Custom Rules for Custom Fields

There’s a filter called ‘mt_apply_custom_field_rules’; unfortunately, in reviewing it to answer this question, I noticed that it was running in a manner that would prevent it from working consistently. You *can* use it; you’d have to add a non-numeric value other than ‘global’ as your ‘context’ value.

E.g., ‘context’ => ‘custom’, then add a filter that applies your custom rules. The filter receives the field array and the event ID to manipulate.

Unfortunately, I have no idea what this means. ??

Question: are these ticket types all part of the same event registration? Or are they separate?

In this case, each of these ticket types are part of the same event. All of these are options for the same registration – but not everyone will choose all of these options.

For example, a couple may register together and choose golf (which needs additional info collected) and card games (which needs additional info collected.)

Well, that’s different then what I was thinking initially. The only way you’ll really be able to do that is by using custom JS to dynamically show and hide options based on chosen ticket types. That’s doable, but it’s outside of what the core plug-in handles.
