The title PRO Plugin Sort on price not working correctly is NOT correct sorry! It should be: “AJAX PRO: Custom field filter not showing the right results”
We have added a custom field “winkelnaam” this is the store name of the sellers on the platform. But if we select a “winkelnaam” the filter ignores the input and shows not only the result of that store.
The issue is, that you are using an user meta field as the filter, but trying to filter a post type (product). User meta fields are to filter user type results, and not post types – it is not possible, as there is no direct relation between them.
Is there any work around or hooks/filters that we can use to manipulate the filter or results.
And can that hook/filter access the user meta field that is chose on the frontend.
Sure, if you want to make changes to the fornt-end filters (visually), then check the filters API. If you want to change the meta query then using the asp_query_args hook may help. The asp_results hook allows changing the final results array.
