Hmmm, spoke too soon. My code now works fine on post archive pages, but I need to add it to the CPT “events” as well, which uses the exact same set of custom fields. But this isn’t working. I can test and see that it is correctly triggering the various if statements, but it doesn’t seem that the meta query gets applied – it just returns all results, unfiltered. Posts are still working, though, with the exact code below. Does this sort of meta query get applied differently to a CPT than to the standard post?
function query_by_relationship( $query ) {
if( is_admin() ) {
return $query;
}
if ((is_archive() && $query->is_main_query()) || ( isset($query->query_vars['post_type']) && $query->query_vars['post_type'] == 'events' ) ) {
if( isset($_GET['sector']) ) {
$meta_query = array(
array(
'key' => 'related_industries',
'value' => '"' . $_GET['sector'] . '"',
'compare' => 'LIKE',
)
);
$query->set('meta_query', $meta_query);
} else if( isset($_GET['pa']) ) {
$meta_query = array(
array(
'key' => 'related_practice_areas',
'value' => '"' . $_GET['pa'] . '"',
'compare' => 'LIKE',
)
);
$query->set('meta_query', $meta_query);
} else if( isset($_GET['lawyer']) ) {
$meta_query = array(
array(
'key' => 'related_people',
'value' => '"' . $_GET['lawyer'] . '"',
'compare' => 'LIKE',
)
);
$query->set('meta_query', $meta_query);
}
}
// return
return $query;
}
add_action('pre_get_posts', 'query_by_relationship');
Well, this is awkward. I had taken that code out of functions.php to try things another way. I pasted back in my code from above, tweaked a few var names as needed, and it worked perfectly fine (whether or not I had the [] in, tried it both ways). So whatever the problem in the code was, it must have been one of the extra bits that I had in there before stripping it down to post on the forum!
Thanks anyway for your response, apparently I just needed a sounding board 😉
