How to mapping a field into extended custom post type ?

I can’t find the “Topic” field in Pods processor.How to mapping ?

Topic — I think bbPress confuses me — is actually the ID of the post in the topic post type. I’m not sure how the link is represented, if it is a meta field or what. If you knew the function to get topic ID by reply ID, I could make you a magic tag for topic ID.

Hi Josh ,
I found the function document. It’s here

I found two function about getting topic ID by reply ID.
output topic ID
return topic ID

Hi Josh,
Could you make a magic tag for topic ID ?

Could you make a magic tag for topic ID ?

Sorry about the delay. Was out of town this weekend and got behind. Try this: https://pastebin.com/KaKHth2C

Sorry, I can’t figure out the relationship between the magic tag and my problem. Because there is no topic field in Pods processor, it can’t send value to bbpress reply.
This is image about my problem.

I’m confused about the context here. Where are you outputting this form? The magic tag I made uses the current post’s ID and passes it to bbp_get_reply_topic_id(). You would need to then save that value wherever bbPress saves that.

Can you tell me where you are outputting this form?

Sorry,my English is not very good. I want to replace bbpress reply form with caldera form.So user can submit reply via caldera form.I am outputting this form in every topic page. The url like this:
https://www.example.com/forums/topic/topic_title/

this is a nice integration. I think the best option is to make a proper form processor for it. it will be way easier and be useful to other users.

I’ll take a look to see if I can get some time to do it or you can try do that using the boilerplate https://github.com/Desertsnowman/cf-formprocessor-boilerplate
