Wordpress内容警告代码
代码加上了user_agent判断，不对搜索引擎的抓取行为显示提醒，避免搜索引擎误判网页内容，直接复制粘贴到主题functions.php即可使用。如需修改样式，修改中间<html>内的html代码即可。

if (isset($_COOKIE['isAdult']) && $_COOKIE['isAdult'] == 'yes') return;

foreach($spiders as $spiderName){
if(stripos($_SERVER['HTTP_USER_AGENT'],$spiderName) !== false) return;
}
add_action('wp_loaded', array($this, 'checkAdult'));
