Thanks,

Your suggestion to setup my own search method using the em_events_get_default_search filter is hardly a workaround but not a solution.

According to page https://wp-events-plugin.com/tutorials/using-additional-custom-taxonomies/

post_category and post_tag both should work when using it in the event_list shortcode or in the EM_Events->output method. And it works for the post_tag parameter, but not for the post_category parameter because of the way how eventmanager finds the taxonomy using the value in field query_var.

Thanks,
Ulf

To answer my own question, why it does not work: it seems like a bug.

The reason is in method
$taxonomies = EM_Object::get_taxonomies() which is being called by
EM_Events::build_sql_conditions() which is called from EM_Events::get()

EM_Object::get_taxonomies() returns:

[23-Jan-2016 00:11:52 UTC]
(
    [category] => Array
        (
            [name] => event-categories
            [slug] => events/categories
            [ms] => event-category
            [context] => Array
                (
                )

            [query_var] => event-categories
        )

    [tag] => Array
        (
            [name] => event-tags
            [slug] => events/tags
            [context] => Array
                (
                )

            [query_var] => event-tags
        )

    [post_category] => Array
        (
            [name] => category
            [context] => Array
                (
                    [0] => event
                )

            [slug] => category
            <strong>[query_var] => category_name</strong>
        )

    [post_tag] => Array
        (
            [name] => post_tag
            [context] => Array
                (
                    [0] => location
                )

            [slug] => tag
            [query_var] => tag
        )
)

and the query for the term is using

$term = get_term_by(‘slug’, $tax_id_clean, $tax_data[‘query_var’]);

The reason why for the post_category element the query_var param is category_name, is because it is definition of the Category taxonomy inside WordPress.
So either WordPress has a bug (which I do not believe) or the event manager should handle the get_term_by call differently.

Any insight?

I forgot to mention that if I add the parameter post_category as shown above the result is the “No Events” text.
