Aha, despite there being a postmeta field of post_name->’slug’, the correct syntax (which mirrors that of WP_Query, is $args = array( ‘name’ => $postSlug, ‘post_type’ => ‘post’, ‘post_status’ => ‘publish’ ); $slugPosts = get_posts($args); Where ‘name’ is the key in the query (for posts, ‘postname’ for page). Doesn’t make much sense but might as well … Read more
Just inspect the current post content for ‘<!–nextpage–>’: function wpse_check_multi_page() { $num_pages = substr_count( $GLOBALS[‘post’]->post_content, ‘<!–nextpage–>’ ) + 1; $current_page = get_query_var( ‘page’ ); return array ( $num_pages, $current_page ); } On page 2 of 3 that returns: Array ( [0] => 3 [1] => 2 ) On an unpaged post it returns: Array ( … Read more
The WP_Query page on the Codex has a section on Order & Orderby Parameters. If you want to order the query by a custom field you should add ‘orderby’ => ‘meta_value’ AND you must also specify the custom field (called your_date_field in the above example) using the meta_key key in the query. $timeline_query = new … Read more
The is_home() conditional returns true when the currently displayed page is the blog posts index. If you want to target the site front page specifically instead, you need to use is_front_page(): function wpse83754_filter_pre_get_posts( $query ) { if ( $query->is_main_query() && is_front_page() ) { $query->set( ‘post_type’, array( ‘home_portfolio’ ) ); } } add_action( ‘pre_get_posts’, ‘wpse83754_filter_pre_get_posts’ ); … Read more
I did something similar, the technique you need to use is called a meta query. Here is the query I wrote to get posts based on a date value stored as a custom field meta value. query_posts( array( ‘post_type’=>’post’, ‘order’=>’ASC’, ‘orderby’=>’meta_value_num’, ‘meta_key’=>’date_event’, ‘posts_per_page’=> -1, ‘meta_query’ => array( ‘relation’ => ‘AND’, array( ‘key’ => ‘date_event’, ‘value’ … Read more
WP_Query is not capable of that kind of logic without a lot of help. There are a few things you can do though: Just run two distinct queries, one for each post type. This is simple and quick but your posts aren’t “mixed” together. I don’t know if that is what you want. You’d then … Read more
The parameter is not supported by WordPress core, but you can implement it using a filter on ‘posts_where’: // require PHP 5.3+ add_action( ‘posts_where’, function( $where, $query ) { if ( isset( $query->query[‘name__in’] ) && is_array( $query->query[‘name__in’] ) ) { global $wpdb; $names = array_filter( array_map( function( $name ) use( $wpdb ) { $sane = … Read more
This is a local/global variable problem. It can be solved either by changing the pagination function to work with local variable, or by promoting the local variable into global scope. As you are using wp_reset_postdata(), i guess you want to keep the original query. Change the pagination function to accept arguments – if ( ! … Read more
Alex, the codex is your friend. You have a parameter orderby which you can set to order posts by comment_count. You can get the complete list of parameters accepted by orderby in the codex page about WP_Query There is no need for any custom query, you can simply just alter the main query with the … Read more
As @bonger said, let your filters accept a second argument, which will be the instance of WP_Query that’s executing the filter, and check it is indeed the main query for an event: function single_posts_fields( $sql, $wp_query ) { if ( $wp_query->is_main_query() && $wp_query->is_singular( ‘event’ ) ) { // Do your stuff } } add_filter( ‘posts_fields’, … Read more
