Return results which match specific post meta data.

Hi Tobias

Ok so I figured out the issue..

There are two things occuring that are causing this:

1) The post meta tab of our search form, is just an admin UI for properties you can use in a WP_Query

2) When you use a checkbox field in ACF, the user can select multiple choices, which means the data is serialised – so for a meta field, instead of a plain value like 2, you have this array(1,2,3)

Now the issue here is, a WordPress query can’t filter this data using a meta query, because the data is serialised (an array)

And we don’t provide a way around this, even though we analyse the post meta to build our cache and use the serialised data correctly in our searches.

The only way to get that to work would be to conver the field into a single value type field, like a radio (you would have to re-save your existing posts to update the post meta) – then you can use the post meta tab to do the things you need.

Now we’ve identified this, I will add it to our v3 roadmap, so the post meta tab will in future be able ot do things like this.

I hope that clarifies things a bit, and it’s a shame we don’t have a solution in place!

Thanks
