This code works: $post_id = wp_insert_post( array( 'post_author' => $user_id, 'post_category' => array(3) ) This does not $post_id = wp_insert_post( array( 'post_author' => $user_id, 'post_category' => array($category_id) ) Using echo, $category_id is indeed 3, so I don't get why this is not working. I'm guessing this has something to do with php and array creation but I couldn't figure out what is wrong. What is the difference between array(3), and array($category_id) if $category_id is 3?
