The problem is almost assuredly your custom loop. I am guessing that this is your problem: $category = get_the_category($post->ID); $category = $category[0]->cat_ID; Further, I’m guessing that the $post object being queried here has more than one category term defined. Thus, $category[0] is returning something other than “tutorials”. Easiest solution: ensure all posts only have one … Read more
You might be running up against WordPress’s global $blog_id variable in test case #2. Try this: foreach($sites as $my_blog_id => $name) { switch_to_blog($my_blog_id); $sites[$my_blog_id] = get_bloginfo(‘name’); restore_current_blog(); }
It’s not clear what you’re looking for here, but you could try to use the posts_where filter: /** * Remove posts, with a given status, on the edit.php (post) screen, * when there’s no post status filter selected. */ add_action( ‘posts_where’, function( $where, $q ) { if( is_admin() && $q->is_main_query() && ! filter_input( INPUT_GET, ‘post_status’ … Read more
Hook your form processing code to an action that runs before the page is rendered and no redirect will be necessary. function wpd_check_submission(){ if( isset( $_POST[‘start’] ) ) { // do your post insertion here } } add_action( ‘init’, ‘wpd_check_submission’ );
You test when the date changes and only show it once, right when it changed for the first time. <?php $date = 0; $newDate = true; if (have_posts()) : while (have_posts()) : the_post(); if ($date == 0) $date = the_date(); else if ($date != the_date()) { $date = the_date(); $newDate = true; } if ($newDate) … Read more
I took the example code you suggested and changed the following to get multicheck support: // Add this at the end of the file // A good prefix for your name prevents problems later! function wpse6513_get_meta_check( $args = array(), $current_values = array() ) { extract( $args ); $name_esc = esc_attr( $name ); if ( ! … Read more
You don’t declare the order of the results when you register the post type. Instead, you do at the time the results are requested. If you’re using WP_Query to get the results then you add your orderby and order arguments to the request. http://codex.wordpress.org/Class_Reference/WP_Query If you want to change the order of the results on … Read more
Most efficient way to list all categories and display a post for each of them?
While you could possibly add a filter to walker_nav_menu_start_el and have your callback function alter/recreate the menu item according to your needs, I would say the best and easiest solution is to implement you own menu walker, and supply that to wp_nav_menu. This should help get you started: class WPSE_90204_Walker extends Walker_Nav_Menu { function start_el( … Read more
I like the idea proposed in this comment. Connecting the posts table to the comments table seems like it’d be some super complicated SQL (well all SQL is complicated to me). Instead the link proposes that you add a post meta field to the post to hold the date of the most recent comment. add_action(‘comment_unapproved_to_approved’, … Read more
