Looking at the WP_Query documentation on tax_queries we can see it accepts a nested array as a parameter. Compare that to the provided code: ‘tax_query’ => array( ‘taxonomy’ => ‘news_category’, ‘field’ => ‘term_id’, ‘terms’ => 82, ), Should look like: ‘tax_query’ => [ [ ‘taxonomy’ => ‘news_category’, ‘field’ => ‘term_id’, ‘terms’ => 82, ] ],
I’m not sure what you exactly need, but normally, by default, get_terms returns only terms that actually have posts assigned to them $terms = get_terms( ‘exhibition’ ); var_dump( $terms ); Apart from this, I really do not know what you exactly need
This query will handle two levels of hierarchy in your taxonomy. More than two levels of hierarchy and you’ll need a recursive self-join. What this does is return the posts in the correct child within parent order. To create the appropriate parent level headings, you’ll have compare the current post’s parent taxon with that of … Read more

This code can’t be added anywhere you want, and it can’t be added to functions.php or any other php file like this. This is a element for the array used to create the WordPress query object. It has to be added via WP_Query class or get_posts and query_posts functions, or via the filter to modify … Read more
The 0 = 1 happens when the terms don’t exist. You’re creating a query for some set of terms. Before it can add the SQL to that main query, it first does a secondary query to get the term_id’s for the relevant terms. If none are found, then it returns 0 = 1 instead, to … Read more
Your problem is that you are not resetting all the needed query variables, like WP_Query::$is_page, WP_Query::$is_single and WP_Query::$is_archive. Also note that ‘pre_get_posts’ is fired for all queries, the main and the secondaries, so you should check that you are working on the main query. Finally, when you get data from $_GETyou should sanitize it before … Read more
Just to start, you say “I am using get_terms to retrieve all terms from Tax 1 with posts associated with it”, however your actual code gets all terms in that taxonomy regardless of whether or not they have posts. You need to set hide_empty to true. So with that out of the way, the bad … Read more
