WordPress实现搜索结果只有一篇文章时自动跳转到文章的方法

代码如下:

add_action('template_redirect', 'redirect_single_post'); 
function redirect_single_post() { 
if (is_search()) { 
global $wp_query; 
if ($wp_query->post_count == 1 && $wp_query->max_num_pages == 1) { 
wp_redirect( get_permalink( $wp_query->posts['0']->ID ) ); 
exit; 
} 
} 
}
