這位老兄其實很“臨”矮，矮到你會怕！他被“邀請”到我的部落客來講鳥話，因爲他本人也很鬼死鳥，和他認識並不久，但這位仁兄很“臨7”照顧我，有什麽是都是他為我出頭，因爲他很矮，大多數人都不扁他。。。給個熱烈的掌聲歡迎他的加入！

After follow Ah Knight’s instruction of updating wp_posts to_ping column, it seem like I can’t perform normal trackback again. I got it fix and download the files here. Or read below for more details, there are 2 files need to be change, which is;

• wp-includes/function-posts.php
• wp-admin/execute-pings.php

file: wp-includes/function-post.php
line of code: 700

if ( empty($to_ping) )
return;

Instead of doing nothing here, we replace the return; to Ah Knight’s code, become;

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

file: wp-admin/execute-pings.php
line of code: 22

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);
}

Some changes made here, make sure to_ping field is clean and make a trackbacks looping!

$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);
}
}

Done, if you not sure what am I explaning above, you can download the file here in zip format, if you are worry the code is not working, backup your original file.

Happy Trackback!
