Relative URL applies the <code>wp_make_link_relative</code> function to links (posts, categories, pages, etc.) to convert them to relative URLs. Useful for developers when debugging local WordPress instance on a mobile device (iPad, iPhone, etc.).
Notice: This plugin SHOULD be used for local development only. I haven’t tested on a production environment; it may work with some issues, like unwanted URLs in RSS feed or sharing URLs are replaced with relative URLs, etc.
More information please visit my <a href="https://sparanoid.com/work/relative-url/" rel="nofollow ugc">site</a>.
For example:
<pre><code>http://localhost:8080/wp/
</code></pre>
Will be converted to:
<pre><code>/wp/
</code></pre>
And..
<pre><code>http://localhost:8080/wp/2012/09/01/hello-world/
</code></pre>
Will be converted to:
<pre><code>/wp/2012/09/01/hello-world/
</code></pre>
And..
<pre><code>http://localhost:8080/wp/wp-content/themes/twentyeleven/style.css
</code></pre>
Will be converted to:
<pre><code>/wp/wp-content/themes/twentyeleven/style.css
</code></pre>
Then after activating this plugin, you can simply access your local instance using <code>http://10.0.1.5:8888/wp/</code> on your iPad or other mobile devices without having styles and navigation issue.
