Hello. Thank you for contacting the Toolset support.
Could you please list down your Parent/Child CPTs and taxonomy information with one dummy example exactly what you want to display so that I'll create one test case for you to guide you exactly how you can achieve this.
I have some custom post types: actors, movie sets and performances
actors and movie sets are parents, performances is the child that acts as the intermediary to create the relationships
the parents have their own categories
i.e. an actor can be tagged with 'comedic'
i.e. a movie set can be tagged with 'outdoors'
i'd like to create a view that lists all the performances with actors tagged as comedic
(this view could go on the main home page)
basically, the child inherits the taxonomy of its parent
**also, a related problem i'm trying to solve:
i'd like to put a view on each performance post, that lists all performances whose parents are tagged with the same categories to the current post
i.e. if the current performance post has an actor parent tagged with 'dramatic', then list performances whose actors are tagged with dramatic
*** Please make a FULL BACKUP of your database and website.***
I would also eventually need to request temporary access (WP-Admin and FTP) to your site. Preferably to a test site where the problem has been replicated if possible in order to be of better help and check if some configurations might need to be changed.
I would additionally need your permission to de- and re-activate Plugins and the Theme, and to change configurations on the site. This is also a reason the backup is really important. If you agree to this, please use the form fields I have enabled below to provide temporary access details (wp-admin and FTP).
I have set the next reply to private which means only you and I have access to it.
I would like to confirm that for CPT performance, I can see that CPT Artist and CPT Venue set as Parent. I do not see any movie CPT.
As I can see there is Genres taxonomy attached to CPT Artists and CPT performance. Do you mean that you want to list all performances for which Artist belongs to specific taxonomy term. For example 'country'?
Which taxonomy term you would like to list post with? For example, there are four Artists posts to which 'country' taxonomy term attached. so you would like to display child (performances) that belongs to this four Artists posts?
the movie/actors was just an example (it's just artists, venues, performances)
yes, i'd like to be able to list all performances where artists is tagged with a specific genre (i.e. show all performances that have a parent artist tagged with country). this view could be placed on the home page or on a page that just displays the performances for a specific genre.
also, if i'm on a particular performance post, i'd also like to create a view where i can list all related performances based on the artist's genre. so if the current performance's artist is tagged with rock, then list other performances whose artists are tagged with rock.
1)
=> Create view 'performancesofparent'
=> Content selection "Performance"
=> add query filter: Post relationship filter
-- Select posts that are a children of the current post in the loop.
=> Add post title to your views loop output section: for example:
<wpv-loop>
<li> [wpv-post-link]</li>
</wpv-loop>
=> Save your view
2)
=> Create view "parentartist"
=> Content selection "Artists"
=> add query filter: select your taxonomy filter and select your taxonomy term for which you want to display post
=> Add 'performancesofparent' to loop output section
This doesn't seem to work for me. Did you get this working?
It shows the Titles of the Artists, but not the performances associated with them. It says no items found.
I'm surprised this is so difficult to do.
As well, I've found a bug:
When I tried to select filter by taxonomy in step 2), it wasn't in the drop down.
BUT, if I switch the Content Selection to Taxonomy and then back to Post type, then it was available in the drop down,
