‘posts_where’ filter not applying ‘WP_Query’ in `wp_ajax`
is_search() is only true if the main query is for the search results. When you create your own query with new WP_Query, you’re not using the main query. Additionally, AJAX requests do not even have a main query, so functions like is_search(), is_archive() etc. do not work. If you want to check if a specific … Read more
Different Results with query(‘s=computer’) vs get_posts(‘s=computer’)?
The default arguments for get_posts() function include ‘numberposts’ => 5. So if you’re querying for a search term that returns more than five (5) results the second query will return a maximum value of 5 unless you pass ‘s=computer&numberposts=-1′ as your query string. The WP_Query object doesn’t have a ‘numberposts’ default, although it is affected … Read more
Compare two meta-fields in a wp_query (where meta-field-A is larger than meta-field-B)
As of writing, there is no meta query compare value that can do what you’re trying to do, which is basically “where <updated_at meta> > <build_ran_at meta>“. But there are two options that you can choose from as an alternative to using the meta_query arg: Use a raw SQL to retrieve just the IDs of … Read more
Revolution Slider Orderby Two Custom Fields
To order by event-end date or start date, your write separate function and call them as per requirement. For example if user clicks on order by start then start function should be called. switch($orderby){ case: ‘event-start’: # your code /* $query[‘meta_key’] = ‘event_start_date’; $query[‘orderby’] = ‘event_start_date’; */ break; case ‘event-end’: #your code /* $query[‘meta_key’] = … Read more
Reduce Database Queries in Code [duplicate]
Because this is very similar to How to reduce the database query-es I will then give you an outline of a possible solution: You have four similar loops with 1) 1 post && offset=0 2) 4 posts && offset=1 3) 5 posts && offset=1 4) 6 posts && offset=1 so your main query will be … Read more
How should I use posts_where to change meta_value from a string to integer?
Try this: add_filter(‘posts_where’, ‘unquote_numeric_meta_value’, 10, 2); function unquote_numeric_meta_value($where, $args) { $value = isset($args->query_vars[‘meta_value’]) ? $args->query_vars[‘meta_value’] : false; if(is_numeric($value)) $where = str_replace(“‘{$value}'”, $value, $where); return $where; }
WP_Query in a shortcode
When you are constructing the $output variable, you need to consider get_the_post_thumbnail() get_the_excerpt() get_the_content() get_permalink() that return the values instead of the_post_thumbnail() the_excerpt() the_content() the_permalink() that echo the values.
What should I use, get_posts or wp_query for less CPU load?
I doubt using get_posts() vs WP_Query() would make any meaningful/noticeable difference in CPU load. Ultimately, get_posts() is just a wrapper for WP_Query(), anyway: $get_posts = new WP_Query; return $get_posts->query($r); You would be better served by looking at the efficiency of the queries themselves; but to provide specific assistance there, we would need to see each … Read more
