WordPress纯代码实现百度收录数据库保存及定时更新

本文于2020年4月12日进行修正,并增加了360收录查询的保存及定时更新

网站文章实现百度收录的查询和显示网上的方法很多,有通过插件实现的,也有通过纯代码进行实现的,但都存在同样的问题:实时查询,一是加载速度会慢,二是可能被封服务器IP。所以我自己做了一个本地数据库版的,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。

1、编辑WordPress主题functions文件,将下列代码放到?>标签之前。

   }
}

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;
}

好了,方法大致就是上面这些,代码可能存在bug,后续有时间再进行优化,写的不好敬请见谅~~
