wprdpress2.0无法Trackbacks"

升级Wordpress2.0以后似乎无法正常trackback，一直以为是对方关闭了trackback，今天 问了海豚才知道是Wordpress2.0的一个bug。有一种 去除数据库中相关数据的方法，不过不太愿意改动数据库，操作比较麻烦，还有后期的问题。

来自終極邊疆BLOG的解决方案如下：

wp-includes/function-post.php line 700:

PLAIN TEXT

PHP:

1. if ( empty($to_ping) )
2. return;

改成

PLAIN TEXT

PHP:

1. if ( empty($to_ping) ) {
2.     $wpdb->query ("UPDATE $wpdb->posts SET to_ping = '' WHERE ID ='$post_id'");
3.     return;
4. }

wp-admin/execute-pings.php line 21:

PLAIN TEXT

PHP:

1. // Do Trackbacks
2. while ( $trackback = $wpdb->get_row("SELECT ID FROM $wpdb->posts WHERE TRIM(to_ping) != '' AND post_status != 'draft' LIMIT 1" )) {
3.   echo "Trackback : $trackback->ID";
4.   do_trackbacks($trackback-> ID);
5. }

改成

PLAIN TEXT

PHP:

1. // Do Trackbacks
2. // The old code will cause infinite loop when trackback failed.
3. //
4.  
5. $trackbacks = $wpdb-> get_results("SELECT ID FROM $wpdb->posts WHERE TRIM(to_ping) != '' AND post_status != 'draft'" );
6.  
7. if ( is_array($trackbacks) && count($trackbacks) ) {
8.     foreach ( $trackbacks AS $trackback  ) {
9.         echo "Trackback : $trackback->ID";
10.         do_trackbacks($trackback ->ID);
11.  
12.     } // end foreach
13.  
14. }

我如此修改以后似乎trackback还有些不正常，有些能ping通，有些则不能，我自己都无法trackback自己。
