The plugin redirects legacy URLs a previous version of a websites that has since been converted into a WordPress site. It can also be used for other redirecting, eg having a short URL that directs to a page as part of a campaign.
Can be directed to:
Simply by adding ‘old-page.html’ as a custom field when editing new-page within WordPress.
Every time a 404 page is called, the Legacy URL plugin checks the database and if it find a legacy-url value that exactly matches the URL it will redirect to the new page.
Please note that this plugin has no settings/options pages within the WordPress admin module.
Things to note
- The plugin converts the url it checks to lowercase, so you should enter the meta value as lowercase.
- The URL is exactly as stated. Eg if you have query strings that can variable you would need to treat each one seperately.
- There is no reason why you can’t have multiple legacy-url meta values associated with a single page. If you have the same meta value associated with multiple pages, the programme will call the first one it finds.
- This is a simple solution, and possibly quite inefficient. It uses header redirects so will effectively process one page and then load another.
- Because it redirects, search engines will not store the campaign/legacy URL but the page it is redirected to. The more sensible ones (eg Google) will note the redirected page and update their internal databases.
- You can change the name of the custom field that the plugin searches by amending the function itself.
- Install and enable the plugin,
- Add a custom field in the post or page with the name legacy-url and the value as the URL excluding the domain name. So if the old page is http://www.example.com/this-is-an-old-page.html, the value of the custom field should be this-is-an-old-page.html.
Please note, there is no longer a requirement to manually amend the 404 page. If you have done so, you should remove the doUrlForwarding(); line from the 404 page.
