First what i see in your “latest FAIL” code you use wrong “operator” (or maybe is just typo). It sholuld work if you change “operator” to ‘operator’ => ‘NOT IN’ tax query parameters UPDATE: for Sablednah comment You can try to hide this term (and “count”) completely by modify WP_Term_Query with something like that: add_action(‘pre_get_terms’, … Read more
You can use filters to modify the SQL. I added something unique in the post_type so I could filter only this query and not change anything else. The query for example $query = new WP_Query(array(‘post_type’=>’something_unique_for_filter’)); And the filter function custom_where($where, $query) { global $wpdb; if(false !== strpos($where, ‘something_unique_for_filter’)) { $where = ” AND post_type=”page” AND … Read more
If you have pretty permalinks enabled and you visit a category archive, the query var that gets populated is category_name. The cat query var will only be populated after the query is run. So while your code will work in a template, it won’t work in a pre_get_posts action for this reason. To fix this, … Read more
if ( $query->is_main_query() && $query->is_singular ) { return; } This is the wrong way around – it’s actually ensuring that the query is being modified on everything except the main query, which is why it’s affecting the menus (which are also built using queries). You need to change it to if ( !$query->is_main_query() && !$query->is_singular … Read more
The post date isn’t meta. You only orderby meta_value if the value is a custom field stored in the wp_postmeta table. The publication date is in the wp_posts table and part of the core post data. If you want to order by date you set orderby to date, and don’t set any of the meta_ … Read more
I think the earliest actions you can hook are muplugins_loaded and plugins_loaded. muplugins_loaded will only fire for Must Use Plugins. Some plugins_loaded pseudo-code: add_action( ‘plugins_loaded’, ‘wpd_plugin_routes’ ); function wpd_plugin_routes() { if( is_a_virtual_file() ){ serve_file(); exit; } } If you want the full WordPress environment, plugins, theme, and authenticated user, right before WordPress parses the request, … Read more
This cannot be done via WP_Query, the orderby parameter can take multiple values, but those are telling it what to order by, aka date, time, title, etc These are the valid values You can specify that it must order by post meta, but you can’t specify more than one post meta, because it uses the … Read more
you need to add your topic to query_vars. function so306156_add_query_vars_filter($vars) { $vars[] = “topic”; return $vars; } add_filter(‘query_vars’, ‘so306156_add_query_vars_filter’); and then, in pre_get_posts, you check for that var and act accordingly: function so306156_manipulate_main_query($wp_query) { if (function_exists(‘is_woocommerce’) && !is_admin()) : if ($wp_query->is_main_query() && is_woocommerce()) { if (isset($wp_query->query_vars[‘topic’])) { $tax_query = $query->get(‘tax_query’); $tax_query[] = [ ‘taxonomy’ => … Read more
WP_Query provides no such date parameter. While you could query for/store the date of the earliest post on the site and then calculate every date for a particular day of the week in the timespan since then and query based on that criteria, it would be far more efficient to track the publish day of … Read more
In your original setup all category queries on the frontend were affected by the pre_get_posts filter you defined. Hence its interference with the menu query. Then you added an extra condition, is_main_query. The result being that both the menu and your main loop were no longer affected by the filter. This can mean only one … Read more
