post_count property of query object will hold amount of posts queried. Note that this is not often used and it is more common to display such elements by conditional logic (is_singular(), is_archive(), etc) or on template level. PS query_posts() is evil and should not be used

You can use get_users(). $args = array( ‘fields’ => ‘all_with_meta’, ); $users = get_users( $args ); foreach( $users as $user ) { // your display code here var_dump( $user ); // so you can see what’s in $user } all_with_meta will get the user and all the associated meta, if I’m reading the Codex page … Read more
Using get_posts(): <?php $category = get_category_by_slug($post->post_name); $template = $category->term_id; $taskarr = array( ‘post_type’ => ‘listing’, ‘post_status’ => ‘publish’, ‘category’ => $template, ‘order’ => ‘ASC’, ‘orderby’ => ‘meta_value_num’, ‘meta_key’ => ‘listing_date’ ); $tasks = get_posts($taskarr); foreach( $tasks as $task ) { echo ‘<li>’; echo $task->post_title; echo $task->post_excerpt; echo get_post_meta( $task->ID, ‘location’, ‘single’); echo ‘<li>’; } ?> … Read more
How does the JSON API work to parse incoming JSON and fetch a post based on an ID?
Super basic example that gets the parents title and content and then the title and content for each child page. This is not just the loop, but an entire page template. <?php include_once( ‘header.php’ ); ?> <?php $my_wp_query = new WP_Query(); $all_wp_pages = $my_wp_query->query(array(‘post_type’ => ‘page’)); ?> <?php if ( have_posts() ) : while ( … Read more
The best solution is create a function that create the output. In addiction this gives more flexibility using function options. The code, tested, is here: <?php function wp_bootstrap_carousel($args=””, $visible = 3, $active = 0) { // cannot show more than 12 items at once if ( ! intval($visible) || $visible > 12 ) return false; … Read more
I would change $args = array( ‘category_name’ => $category, ‘showposts’ => $numposts, ‘order’ => $order ); to $args = array( ‘showposts’ => $numposts, ‘order’ => $order ); if ( $category ) $args[‘category_name’] = $category; This way you never pass an empty category_name parameter as a query arg.

You can use the the_posts filter to loop through the results before they get returned. Proof of concept: function test_the_posts($a) { var_dump($a); die; } add_action(‘the_posts’,’test_the_posts’); I am fairly certain (though I haven’t tested it) that you could pretty easily break pagination and probably other things by fiddling with that, so be careful.
