I’ve taxonomy term called “competition” and “team”. Some of the term from taxonomy “teams” are A, B, C, D. Now what I’m trying to achieve is when I tag the post to “teams”, I also want to post to link to its linked taxonomy “competition”. For example: If team ‘A’, ‘B’, and ‘C’ play in Competition Taxonomy called “Super Cup”, and when I tag to post to A, B or C taxonomy, then the post tagged in any of those teams should show up in query of “Super Cup taxonomy”.
What I’ve tried is using Advance Custom Fields. I applied a rule to taxonomy term “competition” as a new field while creating new taxonomy “competition”. And then I chose a field type relational taxonomy “team”. And when I will create a new taxonomy “competition”, I will have a field of selecting teams as check box( with multiple values choosing ability). I did this way, but this isn’t working. If this isn’t gonna work, is there any way I can link two taxonomy terms of different taxonomy and make one parent and also able to get query post?
So basically this is how it looks.

I made a relationship form between Team and Competition. Example: I have checked few teams for “Demo Competition”. Now I want to show post tagged under those four teams in “Demo Competition” Archive.
Any help would be gladly appreciated.
Thank you!
