You can get the user number = 6 in get_categories like

  $ talentchildren = get_categories (array ('child_of' = & gt; get_category_by_slug ('news') - & gt; word_id, 'number' => 6, 'hide_empty' => 1)); Foreign exchange ($ talent as a child $ talent): echo "prefix"; Print_r ($ talent); Echo "& lt; / pre & gt;"; Endforeach;
