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:

if ( empty($to_ping) )
return;

改成

PLAIN TEXT

PHP:

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

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

PLAIN TEXT

PHP:

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

改成

PLAIN TEXT

PHP:

// Do Trackbacks
// The old code will cause infinite loop when trackback failed.
//
$trackbacks = $wpdb->get_results("SELECT ID FROM $wpdb->posts WHERE TRIM(to_ping) != '' AND post_status != 'draft'");
if (is_array($trackbacks) && count($trackbacks)) {
foreach ($trackbacks AS $trackback ) {
echo "Trackback : $trackback->ID";
do_trackbacks($trackback->ID);
} // end foreach
}

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。

Update:多方修改以后,现在只能trackback日志中的地址。

2006-01-14 Update:执行www.yourdomain.com/wp-admin/execute-pings.php trackback才全发出去
