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!
now i fixed the error of wp2.0 trackback through your post. thank you so much. god bless you!!!
엉뚱이, your welcome 🙂
i’m not sure what’s the exact theory of the upper patch
but it definitely saves my blog~
Thanks a lot~~
My trackbacks quit working ever since I made the mistake of upgrading from 1.5 to 2.0.
They fixed it partially last March (I believe) but now they are back to not working at all.
With this fix I can receive trackbacks but can not send them.
OK, sorry. My trackback actually showed up. It just took about 15 minutes.
Paul Ooi is THE MAN!!! 🙂
Thank you, Sir!
I’m using WP 2.1 and I can’t find those lines in the files you mentioned above. I’m having problems with receiving trackbacks but not sending. Hope someone can help me with this. Thanks! 🙂
