[Plugin: Tweetbacks] [Patch] Find non-rewritten permalinks

I wanted Tweetbacks to also find links that used WordPress’ default URLs, as if the Permalinks setting hadn’t been changed. For example: mysite.com/blog/?p=123. I did this so that my ‘Tweet This’ links could be shorter without using a 3rd-party service.

Here’s the patch for tweetbacks.php version 1.5:
[modification of function yoast_get_tweetback()]

*** 505,510 ****
--- 505,511 ----
        require_once(ABSPATH . WPINC . '/rss.php');

        $permalink = get_permalink($post_id);
+       $defaultlink = get_option('home') . '/?p=' . $post->ID;

        $shorturls = get_post_meta($post_id,"shorturls",true);
        $oldshorturls = $shorturls;
***************
*** 524,529 ****
--- 525,535 ----
                $shorturls['permalink'] = $permalink;
        }

+       // Add the raw permalink of the post itself, e.g. /blog/?p=123
+       if (!isset($shorturls['defaultlink'])) {
+               $shorturls['defaultlink'] = $defaultlink;
+       }
+
        if (!isset($shorturls['tinyurl'])) {
                $result = $snoopy->fetch("https://tinyurl.com/api-create.php?url=".$permalink);
                if ($result && strpos($snoopy->response_code,"200") !== false && $snoopy->results!="" && strpos($snoopy->results,"https://tinyurl.com") === 0) {

Here’s what I put in comments.php for my theme:

<a href="https://twitter.com/home?status=<?php the_title_attribute();?>:+<?php echo get_option('home');?>/%3Fp%3D<?php the_ID(); ?>">Tweet this post</a>

Works a treat.
