WordPress: Force Lowercase URLs
We’re currently migrating a website which has some URLs with uppercase letters to WordPress. WordPress slugs are always lowercase. We are creating identical URLs, but the case will be different. This will result in a bunch of 404 errors for anybody linking to a capitalised version of a page.
We could just setup a 301 redirection for each uppercase url to the lowercase version, but that would be tedious. Instead we’ve created a little WordPress plugin that checks if the URL contains uppercase letters and performs a 301 redirection to the lowercase URL.
