You have to declare $popular to be global before you use it. Based on the code you’ve posted you haven’t done that. global $popular; $popular[] = 1 //post id=1 $popular[] = 2 //post id=2 $popular[] = 3 //post id=3 However, if you mean the index.php in the theme, that file is not always used. You … Read more
Actions don’t typically return data, so I doubt you will get this working the way you are trying to. Something like… function cpt_pre_post_publish(){ global $my_error; $my_error = new WP_Error(‘error’, __(‘Error!’ )); } add_action(‘pre_get_posts’, ‘cpt_pre_post_publish’); … should set a variable that you could access in a template file with… global $my_error; var_dump($my_error); It is really not … Read more
I believe the shortest and best approach is to (1) modify the query: function search_faqs_metadata($query) { if(!is_admin() && $query->is_main_query()) { if($query->is_search) { $query->set(‘meta_query’, array(array( ‘key’ => ‘_faqs’, ‘value’ => $query->query_vars[‘s’], ‘compare’ => ‘LIKE’ ))); } } } add_action(‘pre_get_posts’, ‘search_faqs_metadata’); and then (2) replace the AND with OR via the get_meta_sql filter: function change_meta_key_where_from_and_to_or($sql) { if(is_search()) … Read more
I haven’t run this code so there may be a syntax error, but the gist is to return userfeed-taxonomy with the terms specified that have featured category OR cities-taxonomy with the terms specified and featured category OR anything else that’s not those taxonomies. It’s kind of clunky, maybe there is a better way: $query->set( ‘tax_query’, … Read more
You are invoking an infinite loop, because you are calling WP_Query inside WP_Query, which is where the hook resides, so you are hooking it into parse_query over and over again. To avoid it, put the following at the beginning of your callback function: // avoid infinite loop remove_action( ‘parse_query’, __FUNCTION__ ); Additional note, it might … Read more
pre_get_posts does not work on page templates and static front pages. It will 404. If I read the WP_Query class correctly, the page ID is passed to a parameter such as p once the URL is parsed. You can try unsetting this parameter and check if it changes the query, but I doubt if this … Read more
I think the cleanest method here is just run a custom query, get the ID and then remove that post from the main query with post__not_in. You can additionally run a query inside a function and then call the function in your featured section and in pre_get_posts. There is another way, using a global to … Read more
I think this would be easier if you had the performance_datetime custom field, because that could simplify your meta query. The following is just a demo fun for you to play with: As far as I understand the problem, you get three INNER JOINS on the wp_posts table, namely wp_postmeta, mt1 and mt2. But the … Read more
This looks good. If we assume get_exclusion_IDs_for_cats_by_name($cat_names); works correct then you are doing it right. Your question may be rephrased like this: Can I call other functions inside the custom actions? And the answer is yes. The only thing you need to be careful is that your other function is available from where you call … Read more
Note this problematic line: $query->set( array( ‘date_query’ => array( it should be $query->set( ‘date_query’, array( So try instead this form: $query->set( ‘date_query’, [ [ ‘after’ => ‘January 1st, 2013’, ‘inclusive’ => true, ] ] );
