WordPress bloggers will sometimes copy headlines from a WordPress-generated homepage and paste them into the post-editing window. In Firefox, this has the unfortunate result of converting absolute urls into relative ones. For example, copying a headline from http://khaotica.com converts the permalink for this article:
http://khaotica.com/2009/12/firefox-relative-links-fix-wordpress.html
…to a relative link:
../2009/12/firefox-relative-links-fix-wordpress.html
This creates broken links when the post is viewed on the archive page and RSS feed. The links will also be broken for subscribers who receive posts via email.
Enter the Relative Links Fix. This plugin will replace relative urls with the proper absolute urls every time you save or publish a post. If you use WordPress and can’t shake those copy-paste habits, this is the plugin for you.
As always, donations are appreciated. I promise to spend them exclusively on soda (the creative fuel that powers developers everywhere).

Relative Links Fix

Corrects Firefox behavior in which pasting formatted content in the editor converts absolute URLs to relative URLs.

<li>Develop/stage in one domain, go live in another.</li>
<li>Backup a production site from one domain, restore to a test site at another domain.</li>
<li>Migrate from one domain to another with minimal effort.</li>
<li>Ease migration between stand alone and multi-site installations.</li>
<li>Ease migration between domain and sub-folder installations.</li>
<li>Switch between ssl and non-ssl sites.</li>
<li>Always present your content in an SEO friendly way.</li>
</ul>
We aim to achieve these capabilities with this plugin. The idea is to remove creator urls as content is produced, and play the current url when content is viewed. By default, WordPress saves the local url with content, and that makes it a challenge to access your content from a different domaim, even when you have a legitimate reason to do so.
This plugin makes your WordPress content adaptable in that you can present content from a domain other than the one in it which it was produced. It achieves this by saving URLs as relative URLs. At the same time it supports SEO requirements by reverting to absolute URLs when content is viewed.
In addition to moving the whole site to a new domain, you can identify specific domains as being related. This allows you to copy raw content from one related site and paste it into another. The plugin will recognize the related domain and remove it as it gets saved. Then it will display the absolute URLs of the current domain when it is viewed.
For the technically inclined, the plugin removes the get_bloginfo(‘url’) and get_bloginfo(‘wpurl’) parts of a URL as content is saved and inserts them again as content is viewed.
We use context and some configurable rules to determine when to apply conversions in both directions. Most of the time you can go with the defaults. If you have a situation where something doesn’t appear to work, let me know your experience (with as much detail as possible please).

Absolute Relative URLs

Awesome! Thanks for this plugin! I’m still asking myself how one could work without a plugin like this one? WordPress out of the box does not support staging or even switching from a subdomain-blog to a FQDN. Adding SSL support to pages afterwards would be a disaster without this plugin!



I’ve been using >Root Relative URLs for ages but that is no longer maintained and does not work e.g. with Google’s reCaptcha. This one is a great successor and does the job very well and even better.

As of WP v.6.4.1 (2023-11) this still works like a charm. And I still highly recommend this plugin!



A hint to people having trouble understanding what this plugin does: It will remove the base url from links when saving e.g. a page and adds it back when being loaded or viewed.



That means: After you activated it, it will do nothing.



This is a nice behavior, because the plugin doesn't know what you want. And instead of trying to do magic that might fail, you have to update your content by yourself.



This can either be done by re-saving every page/post manually or by using  your DB tool and doing a simple string replacement that removes the base url from internal links like this:



update wordpress.wp_posts set post_content = replace(post_content,'https://www.example.com','') where post_content like '%https://www.example.com%';



And in fact, you won't see a change on your page or post and this is good. It's just important that you get rid of the absolute URLs in the database to be able to do staging, migration etc. without any hassle.

Must use for staging, SSL sites and multisite-blogs
