As of WordPress 3.0, most of this plugin’s original features have been incorporated into WordPress itself. WordPress adds shortlinks to most pages by default. This plugin simply adds a settings page where you can easily make some minor adjustments.
WordPress shortlinks are useful for micro-blogging, by using your own domain instead of a 3rd-party short URL service.
The URLs are automatically added to the HTTP and HTML headers of each post, page, attachment, and category.
A template tag enables you to display a human-readable link in addition to the automatically generated headers. Use of human-readable links is highly encouraged, because Google is known to favor them and rank them higher than some longer URLs. This has the effect of boosting the rank of URLs that were deemed “too long” by Google’s standards. Also, in many mobile web browsers, the easiest way for a visitor to find a short link is by seeing it somewhere on the page.
The template tag idea can be extended further with CSS code for print media, which could ensure that each article’s short link URL is printed along with the article. This will make it much easier for the user to return to the article after reading a hard copy.
<h3>Theme</h3>
Current documentation should be found at <a href="https://codex.wordpress.org/Function_Reference/the_shortlink" rel="nofollow ugc">Function Reference/the shortlink</a>
Here is a basic reference for the template functions provided by Simple Short Links. WordPress 3.0+ users, see also wp-includes/link-template.php for more details about the_shortlink().
<pre><code>/**
 * Template Tag for Displaying the Short Link
 *
 * Must be called from inside "The Loop"
 *
 * Call like <?php the_shortlink(__('Shortlinkage FTW')); ?>
 *
 * @since 1.1
 * @param string $text Optional The link text or HTML to be displayed. Defaults to 'This is the short link.'
 * @param string $title Optional The tooltip for the link. Must be sanitized. Defaults to the sanitized post title.
 */
function the_shortlink($text = '', $title = '');
</code></pre>
A second, similar tag is now available in case you need to display a self-referring short link on a category page.
<pre><code>/**
 * Template Tag for Displaying the Short Link for a Category
 *
 * Should be called from outside "The Loop"
 *
 * Call like <? the_single_shortlink(__('Shortlinkage FTW')); ?>
 *
 * @since 1.3
 * @param string $text Optional The link text or HTML to be displayed. Defaults to 'This is the short link.'
 * @param string $title Optional The tooltip for the link. Must be sanitized. Defaults to the sanitized category name.
 */
function the_single_shortlink($text = '', $title = '');
</code></pre>
<h4>The CSS Printing Trick</h4>
Try adding something like this to your theme’s CSS file to make the URL for the short link appear when printed.
<pre><code>@media print {
 .shortlink a:link:after {
 content: " " attr(href);
 }
}
</code></pre>
The CSS example assumes the_shortlink() is used inside of a DIV or P element with a class attribute called “shortlink”.

Use shortlinks instead of permalinks in Jetpack sharing buttons
<ul>
<li>If you haven’t set up any shortlink plugin on your site, the sharing buttons will use the default numerical permalinks</li>
<li>If you have enabled WP.me Shortlinks in Jetpack, the sharing buttons will use them</li>
<li>If you’ve installed another plugin to create custom shortlinks, the sharing buttons will use them</li>
</ul>
Important: for this plugin to work, you must activate <a href="https://wordpress.org/extend/plugins/jetpack/" rel="ugc">Jetpack</a> first, and activate the Sharing module.
This plugin is a work in progress. You can report issues <a href="https://wordpress.org/support/plugin/jetpack-shortlinks-for-sharing-buttons/" rel="ugc">here</a>, or submit a pull request <a href="https://github.com/jeherve/jp-sd-custshortlink" rel="nofollow ugc">on GitHub</a>.
