WordPress实现百度收录数据库保存及定时更新

前面有一篇文章:《WordPress给文章添加百度是否已收录的功能》,搜索引擎收录情况如果直接使用实时查询然后在文章或后台展示,会拖累网站加载速度。今天我们为大家推荐一个更好的版本,可以将查询结果保存到本地,从本地读取显示,当查询结果大于设定的时间后,自动进行查询结果更新。

本方法可实现查询结果自由显示,可在后台文章列表显示,也可在文章也显示,取舍可自行决定。
方法如下:

1、将下列代码放到自己WordPress主题的目录下的functions 文件中。

    if($wpdb->get_var("show tables like $table_name") != $table_name) {  //判断表是否已存在
        $sql = "CREATE TABLE " . $table_name . " (

function baidu_record() {

        echo '<a>百度已收录</a>';
   } else {
        echo '<a style="color:red;" rel="external nofollow noopener noreferrer" title="点击提交,谢谢您!" target="_blank" href="http://zhanzhang.baidu.com/sitesubmit/index?sitename='.get_permalink().'">百度未收录</a>';
   }
}
function ssl_record() {
    if(sslrecord(get_permalink()) == 1) {
        echo '<a>360已收录</a>';
   } else {
        echo '<a style="color:red;" rel="external nofollow noopener noreferrer" title="点击提交,谢谢您!" target="_blank" href="http://info.so.com/site_submit.html">360未收录</a>';
   }
}

2.编辑当前主题下的文章模板(一般是single.php),在想要显示收录结果的位置添加如下代码并保存:

<?php echo baidu_record(); ?>

如果不想给其他人看到这个收录情况,可以加上一个判断语句,具体代码如下:

<?php if ( is_user_logged_in()){baidu_record();ssl_record();}?>

3.如果想在后台文章列表显示百度收录情况的话,将下来代码放到主题functions文件最后一行的?>之前。

//1~ 在后台文章列表增加1列数据,展示百度收录情况
add_filter( 'manage_posts_columns', 'yy_customer_posts_columns' );
function yy_customer_posts_columns( $columns ) {
  $columns['baidurecord'] = '百度收录';
  $columns['baidurecord'] = '360收录';
  return $columns;
}
  
//2~ 输出查询结果
add_action('manage_posts_custom_column', 'yy_customer_columns_value', 10, 2);
function yy_customer_columns_value($column, $post_id){
    if($column=='baidurecord'){
$baidurecord = $wpdb->get_var("SELECT value FROM wp_record WHERE post_id = '$post_id' and record_name = 'baidu_record'");
if($baidurecord == 1) {
            echo Yes;
        }else{echo No;}
}
    if($column=='sslrecord'){
$sslrecord = $wpdb->get_var("SELECT value FROM wp_record WHERE post_id = '$post_id' and record_name = '360_record'");
if($sslrecord == 1) {
            echo Yes;
        }else{echo No;}
}
    return;
}
