Take a look at the WordPress Codex: http://codex.wordpress.org/Plugin_API/Filter_Reference/posts_orderby function edit_posts_orderby($orderby_statement) { $orderby_statement = “meta_value DESC”; return $orderby_statement; } add_filter(‘posts_orderby’, ‘edit_posts_orderby’); If you’re making the WP_Query yourself you can change the orderby parameter to meta_value Take a look here: http://codex.wordpress.org/Class_Reference/WP_Query
Updating a theme isn’t that hard. But it’s necessary to let it play nice with the current version of the core. Here’re some notes on what you might need to do: Query Templates Post Thumbnails & featured images The query Nowadays, we’re using get_posts() or new WP_Query for such cases, where you need to do … Read more
As per its laconic source: function get_queried_object() { global $wp_query; return $wp_query->get_queried_object(); } This function retrieves object from main query. As such it is affected by anything that changes main query. From your list that would be query_posts() (reason number umpteen it should not be used).
add_action( ‘add_meta_boxes’, ‘attached_images_meta’ ); function attached_images_meta() { $screens = array( ‘post’, ‘page’ ); //add more in here as you see fit foreach ($screens as $screen) { add_meta_box( ‘attached_images_meta_box’, //this is the id of the box ‘Attached Images’, //this is the title ‘attached_images_meta_box’, //the callback $screen, //the post type ‘side’ //the placement ); } } function … Read more
The simplest way is, in all honesty, to hook into wp_title and change things, and just be aware that the warnings are there but not showing in production (because you’ve property configured your server). What follows is a kind of hacky solution. If you take a look at get_queried_object… <?php function get_queried_object() { global $wp_query; … Read more
You have to declare $popular to be global before you use it. Based on the code you’ve posted you haven’t done that. global $popular; $popular[] = 1 //post id=1 $popular[] = 2 //post id=2 $popular[] = 3 //post id=3 However, if you mean the index.php in the theme, that file is not always used. You … Read more
The cat and category_name parameters for WP_Query display “posts that have this category (and any children of that category)”. There are also examples of doing this in the Codex. $query = new WP_Query( ‘cat=4’ ); // or $query = new WP_Query( ‘category_name=staff’ ); I am not 100% sure what you mean by “I need all … Read more
You probably also need: $query->set( ‘ignore_sticky_posts’, true ); That will prevent sticky posts from shuffling to the top. Maybe: $query->set( ‘posts_per_page’, -1 ); If you are getting too few posts. -1 means “all”. You can use that to change to a number other than what is set in the backend. A couple of notes: $query->set( … Read more
Is there a $wpdb method available that will allow me to create the query, by looping through my query, and then execute it once I’m out of that loop? If you and your loop can construct the proper SQL, then use $wpdb->query. You can run any query you want with that, so whatever version of … Read more
