Performance optimization doesn’t really work in vaccum, it takes hands-on profiling an looking for actual bottle necks (which often turn out to be different from perceived ones). But it general there are several approaches to the need of lots of database data: Optimize fetching from database, for example by concatenating multiple requests into retrieving single … Read more
Switched the loop from using to WP_Query to get_posts.
Have you tried simply omitting the ‘terms’ key from the ‘tax_query’ array? $query03 = array( ‘numberposts’ => 5, ‘post_type’ => array( ‘video’ ), ‘tax_query’ => array( array( ‘taxonomy’ => ‘product’, ‘field’ => ‘slug’ ) ) ); Alternately, I wouldn’t really worry about the weight of the query. The resulting query will be what it will … Read more
Yes, use caching. But even with caching you should rethink what you are actually doing because the cache for page/2 should change every time you publish a new post which might make caching pointless depending on the amount of traffic to that page. You should probably rethink what you are trying to achieve there, why … Read more
From get_media_items function and his code, you can use get_children adding mime type for images: $images = get_children( array( ‘post_parent’ => $post_id, ‘post_type’ => ‘attachment’, ‘post_mime_type’ => ‘image’, ‘orderby’ => ‘menu_order ASC, ID’, ‘order’ => ‘DESC’) ); That will get you an array ($images) of images attached to $post_id. In you case, if you’re inside … Read more
You have to use your object like this : while ( $query->have_posts() ) : $query->the_post();
If I understand you correctly you want a bunch of posts from a custom post type and in some way combine it with a page. To do this you would first have to get the queried objects: $page_id = 123; // the id of the page you want to retrieve $cpt_objects = new WP_Query( array( … Read more
Finally I’ve figured out the correct coding for this problem: <?php $paged = (get_query_var(‘paged’)) ? get_query_var(‘paged’) : 1; $wp_query = new WP_Query(); $wp_query->query(‘tag=concurs&posts_per_page=”.get_option(“posts_per_page’).’&paged=’ . $paged); ?> <?php if ($wp_query->have_posts()) : ?> <?php while ( $wp_query->have_posts() ) : $wp_query->the_post(); ?> [code for title, author, category, meta-info etc] <?php endwhile; ?> <div class=”next-prev”><?php posts_nav_link( ‘ ‘, ‘<img … Read more
In pure SQL you can use comma separated strings to do what you want– that is, something like ORDER BY post_type,post_name,post_date. However, WP_QUERY will not allow that kind of thing to pass through. There is a rigid set of allowed values. There are a couple of ways I can think of to do this. You … Read more
You cannot declare multiple functions with same name in PHP. Codex examples for this are technical demonstration, rather than ready-made usable snippet. Give your filter functions unique names, that are not likely to clash with your own or third party code.
