只需添加\'post__in\' => get_option(\'sticky_posts\') 对于您的查询，将您的查询限制为仅限于粘性帖子。所以

$getHighlights = array(
    \'numberposts\' => 7,
    \'post_type\' => array(\'post\',\'Event\'),
    \'post__in\' => get_option(\'sticky_posts\'),
    \'category_name\' => \'Highlights\'
);

编辑：这是如何合并两个数组以获得位于查询顶部的粘性帖子：

$getHighlights_sticky = get_posts( array(
        \'numberposts\' => 7,
        \'post_type\' => array(\'post\',\'Event\'),
        \'post__in\' => get_option(\'sticky_posts\'),//it should be post__in but not posts__in
        \'category_name\' => \'Highlights\'
    ));
$getHighlights_other = get_posts( array(
        \'numberposts\' => 7 - count( $getHighlights_sticky ),
        \'post_type\' => array(\'post\',\'Event\'),
        \'post__not_in\' => get_option(\'sticky_posts\'),//it should be post__not_in but not posts__not_in
        \'category_name\' => \'Highlights\'
    ));
foreach ( array_merge( $getHighlights_sticky, $getHighlights_other ) as $post ) {
    setup_postdata( $post );

    // your display loop

}
