伊阳博客领袖和跟风者的区别就在于创新!——史蒂夫.乔布斯
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~~
