What does setup_postdata ($post ) do?

Template tag functions rely on global variables to access the post being processed and retrieve data from it or related to it.

get_posts assigned to a specific custom taxonomy term, and not the term’s children

In looking at the WP_Tax_Query class in /wp-includes/taxonomy.php, I found that there is a ‘include_children’ option which defaults to true.

When to use WP_query(), query_posts() and pre_get_posts

It is most often used to alter only the ‘main query’: add_action(‘pre_get_posts’,’wpse50761_alter_query’); function wpse50761_alter_query($query){ if( $query->is_main_query() ){ //Do something to main query } } (I would also check that is_admin() returns false – though this may be … Read more
