That’s not how WP_Query works, it isn’t what the documentation says either. WP_Query is not a function. foreach needs an array, or something that can be iterated on, but you’ve given it a WP_Query object. Instead, look at the documentation or tutorials, all of them follow this basic pattern for a standard post loop: $args … Read more
The close() function was added for completeness in the database abstraction. If the database is prematurely closed in a plugin or theme (as you are using it), the next call to wpdb::query() will re-open the connection. Your Commands out of sync error is a MySQL error, not a WordPress one, and it might be coming … Read more
Here’s a plugin that uses the posts_orderby filter to support a custom _post_type__in orderby in WP_Query that orders the post types by their array placements: <?php /** * Plugin Name: Support for _post_type__in orderby in WP_Query * Plugin URI: https://wordpress.stackexchange.com/a/392910/26350 */ add_filter ( ‘posts_orderby’, function ( $orderby, \WP_Query $q ) use ( $wpdb ) { … Read more
On your if(), it should be like this: if (!($wpdb->get_row(“SELECT voter_ip FROM ” . $wpdb->prefix . “voter_ips WHERE post_id = $post_id AND voter_ip = ‘$voter_ip'”) Notice the quotation mark added on $voter_ip.
The filter on posts_orderby should return a string that does not begin with ORDER BY, WordPress will add that itself. By default WordPress will filter by post_date. If you don’t want that, you should overwrite the order clause, not append to it. So your filter should look like this: function filter_orderby( $orderby ) { global … Read more
Just do the get_users() twice and merge the results: <?php $friends = get_users( array( ‘role’ => ‘friends’ ) ); $enemies = get_users( array( ‘role’ => ‘enemies’ ) ); $friends_n_foe = array_merge($friends, $enemies); $IDs = array(); foreach( $friends_n_foe as $person ) { $IDs[] = $person->ID; } $news = new WP_Query( array( ‘author’ => implode( ‘,’, $IDs … Read more
check if the $GET[‘rating’] is set ( isset($_GET[‘rating’]) or has any value. ( !empty($_GET[‘rating’]) if not, build the query fecthing all post without ‘meta_query’ for example: if ( (isset($_GET[‘rating’]) && !empty($_GET[‘rating’]) ) { // restrict $meta[] = array(( ‘key’ => ‘rating’, ‘value’ => $_GET[‘rating’] ); } if ( (isset($_GET[‘tax’]) && !empty($_GET[‘tax’]) ) { $meta[] = … Read more
‘post_id’ is not a valid page/post parameter for WP_Query(). Try using p or post__in instead: array( ‘p’ => 700 ) or array( ‘post__in’ => array( 700 ) )
I’m not quite sure how you’re defining whether or not the current page has only “small” images. But I suspect the answer is right in the wp_get_attachment_image_src function, which returns not just the image url but also the width and height. So let’s say you were only interested in images that are more than 300 … Read more
Try the following and see how you go.. <?php global $paged; global $wp_query; $temp = $wp_query; $wp_query = null; $wp_query = new WP_Query(); $wp_query->query(‘posts_per_page=10&post_type=your_post_type’.’&paged=’.$paged); while ($wp_query->have_posts()) : $wp_query->the_post(); ?> <!– do your loop output here, title, content etc –> <?php endwhile; ?> <?php previous_posts_link(‘« Newer’) ?> <?php next_posts_link(‘Older »’) ?> <?php $wp_query = null; $wp_query … Read more
