Mashup of multiple categories fails

[mapbeat]

Since 2.38.2

Mashups of multiple categories fail to an empty map

query=”category_name=1,2,3″ no longer works

query=”category__in=1,2,3″ doesn’t work
How do we write queries for multiple category mashups?

Thanks,
Keith

Hi,

It may be a bug.  Please upgrade to the latest (2.38.5).

I just tested that version with category__in and it worked fine for me.  I’m assuming you’re using slugs for category_name and IDs for category__in.

Here’s how I wrote my mashup:

[mashup query="category__in=1543,1531"]

The problem is in 2.38.5. From your reply I’m guessing that

category_name=1,2,3 is for category names and

category_in=1,2,3 is for category IDs.

If that is correct, the problem occurs with category_name.

Hi,

Category_name is for category slugs, which are not always the same as the description.  Are you using slugs?

If so, can you provide an example of your complete mashup shortcode?

Hi,

I think I see the problem: if you read the WordPress documentation carefully it mentions that category_name only takes a single slug as a parameter, not an array (list) of terms:

Here’s an excerpt from http://codex.wordpress.org/Class_Reference/WP_Query

• category_name (string) – use category slug (NOT name).
• category__and (array) – use category id.
• category__in (array) – use category id.
• category__not_in (array) – use category id.

There are a few examples in the mappress documentation.
