wordpresss百度数据推送优化以及设置

在functions.php中增加了如下代码：

/**
* WordPress百度搜索自动推送、主动收录JS优化
**/
add_action( 'wp_footer', 'bdPushData', 999);
//检查百度是否已收录最新改进版本
if(!function_exists('baidu_check_record')){
  function baidu_check_record($url){
    global $wpdb;
    $post_id = ( null === $post_id ) ? get_the_ID() : $post_id;
    $baidu_record  = get_post_meta($post_id,'baidu_record',true);
    if( $baidu_record != 1){
        $url='http://www.baidu.com/s?wd='.$url;
        $curl=curl_init();
        curl_setopt($curl,CURLOPT_URL,$url);
        curl_setopt($curl,CURLOPT_RETURNTRANSFER,1);
        $rs=curl_exec($curl);
        curl_close($curl);
//如果抓取到的百度结果中不存在【提交网址】这个关键词，则认为该页面已被百度收录
        if(!preg_match_all('/提交网址/u',$rs,$matches) && preg_match_all('/百度为您找到相关结果/u',$rs, $matches)){
            update_post_meta($post_id, 'baidu_record', 1) || add_post_meta($post_id, 'baidu_record', 1, true);
            return 1;
        } else {
            return 0;
        }
    } else {
       return 1;
    }
  }
}
//输出百度自动推送js代码
if(!function_exists('bdPushData')){
  function bdPushData() {
    if ($_SERVER['HTTPS'] != "on") {
        $currentUrl = 'http://'.$_SERVER['HTTP_HOST'].$_SERVER["REQUEST_URI"];
    } else {
        $currentUrl = 'https://'.$_SERVER['HTTP_HOST'].$_SERVER["REQUEST_URI"];
    }
    //判断是否是未收录页面，并且当前页面是否等于正规url地址(get_premalink)
    if(baidu_check_record(get_permalink()) == 0 && $currentUrl == get_permalink()) {
        echo "";
      }
   }
}
