Sticky Links – WP Multilingual
The Sticky Links plugin keeps internal links from ever breaking. It automatically tracks linked pages in your site and keeps all incoming links up-to-date. When you change permalink structure, hierarchy and even page slugs, all incoming links update immediately.
When you add a regular link to a page or a post, WordPress saves the URL of that page as the link. This means, if the URL changes, the link is broken.
WordPress makes it all too easy to change page addresses, causing all incoming links to go broke (404 error). Here are a few ways to do that:
Change the page’s parent
Change the slug
Change the site’s permalink structure
Sticky Links – WP Multilingual prevents changes in URLs from breaking incoming links. When you create a link, automatically makes it Sticky. Instead of storing the URL of that page (at the time the link was created), it stores the page number. This can never change, no matter what you do.
Then, when the page is displayed, Sticky Links – WP Multilingual inserts the permalink of the page you’re linking to. Whenever the URL changes all pages linking to it update immediately and will link to the correct address.
This screen shot shows how internal links look like in the database, once Sticky links are enabled:
Links turned Sticky by Sticky Links – WP Multilingual
Your users will never see these “strange” links. Instead, Sticky Links – WP Multilingual will replace them with the current permalinks when displaying the pages.
Once you enable the Sticky Links module, you can control what strings it handles. Go to Sticky links.
