To make an array, separate your values with commas rather than concatenate them with periods. $upostcat= array ( $video, $image, $audio, $writing, $event ); That part is pure PHP. However, I notice you want to use the category_name “array”. If you are talking about WP_Query, category_name does not accept an array– really this is the … Read more
If it is possible at all, this is how it would be done: $searchquery = new WP_Query( array( ‘s’ => ‘hello ‘ )); Since all queries boil down to WP_Query at their most basic level, we can determine if it is possible using the WordPress APIs by looking at the code in wp-includes/query.php // If … Read more
In the function widget( $args, $instance ), which generates the widget output, add the following code before the echo $after_widget; line: // The Query $the_query = new WP_Query( array( ‘post_type’ => ‘page’, ‘posts_per_page’ => ‘3’ ) ); // The Loop while ( $the_query->have_posts() ) : $the_query->the_post(); echo ‘<li>’ . get_the_title() . ‘</li>’; endwhile; Additional information … Read more
I am assuming that ‘country’ is a custom meta field. In that case, you need this (very much like one of the examples in the Codex): $loop = new WP_Query( array ( ‘post_type’ => ‘europe’, ‘posts_per_page’ => -1, ‘orderby’ => ‘meta_value’, ‘meta_key’ => ‘country’ ‘order’ => ‘asc’ ) );
Here is the way I think it should work: $args = array( ‘post_type’ => ‘item’, ‘post_status’ => ‘publish’, ‘posts_per_page’ => -1, ‘tax_query’ => array( array( ‘taxonomy’ => ‘color-categories’, ‘field’ => ‘slug’, ‘terms’ => array(‘red’, ‘2000’), ‘operator’ => ‘AND’ ) ) ); So you query posts which are in both red and 2000 using operator AND.
Yes, if you need to run WordPress/PHP functions from a button click (Javascript), you need Ajax. In the following example, a shortcode will render a button (id=”newquote”) that calls an Ajax action hook (get_random_cpt). A query is done and replaces one div from that shortcode (id=”randomquotes”) with the results. How to Use Ajax in a … Read more
If you are going to do this is SQL, use a subquery. SELECT *, (SELECT meta_value FROM wp_commentmeta WHERE meta_key = ‘your-meta-key’ AND wp_commentmeta.comment_id = wp_comments.comment_ID LIMIT 1) as comment_author FROM wp_comments Instead of the *, enumerate the fields you want but leave out comment_author. Obviously, $wpdb functions to keep the table names straight.
There is a difference because you are not using the_post function in the first example. What this function does is it calls setup_postdata function, which sets up all the globals needed for other functions to work. You can call it manually, just at the beginning of your foreach loop, like this: setup_postdata( $post ). In … Read more
Change your $args array a little bit: $args = array( ‘post_type’ => array( ‘my_projects’ ), // it need to get the posts from this post_type ‘order’ => ‘DESC’, ‘posts_per_page’ => 5, ‘project_tags’ => $term // search taxonomy ); Other ways to search for taxonomy terms can be found here in the WordPress Codex pages. Answer … Read more
You can get the selected page for posts by the following code: $page_for_posts = get_option( ‘page_for_posts’ ); Then, get the requested post by: $post = get_post( $page_for_posts ); And, get the data you need: echo apply_filters( ‘the_title’, $post->post_title ); echo apply_filters( ‘the_content’, $post->post_content ); echo get_post_meta( $post->ID, $key, $single);
