Add a meta query to a query loop where posts are filtered by Metabox relation

[Patric]

I hear you.

But relationship queries are not just simple queries, therefore the implementation is more complicated. Also, I don’t think you really want your customer to change query parameters either.

Anyway, you can of course make a first query of the post type and its posts, and within this query make a second query where you check in the meta query parameters for the post_id.

Or when you are in a single post template, you can make a query in that template with the meta query parameter for the post_id.

Both will then find all related posts that have the post_id of the post from the first query or from the single post template.

Then you have all sorting etc. query parameters.

Tipp: How to Meta Query for ACF Bi-Directional Query

Hi there just solved an issue with a custom query for an ACF bi-directional query. If you want to find all posts for an ACF relationship field (in my example the field chochete_rezepte), but the bi-directional way, you can enter this into the meta query: [ACFBidi] What I’ve just learnt is that you have to add the " before and after the post_id. This prevents a match for “1234” when the post_id is “123”. So make sure that the post_id is entered like this including the ": "{post_id}" Cheers …

The meta key has to be the name of the relationship field and the meta value must be “{post_id}” including the quotes!

Cheers
