Don’t know if any one would find this useful. I didn’t like cased tags and I just decide that lowercase is the way to go. I know you can do it with CSS but that’s not the result I want.
UPDATE `wp_terms` SET name=LOWER(name);
I had many tags are some are in capitals, some are in small letters, it looks really messy from my admin panel so I decided to clean of every thing.
You can run the above command in your SQL too if you want to do something similar. It converts tags like ‘Beverage’, ‘WordPress’, ‘Jokes’ and ‘McDonalds’ to ‘beverage’, ‘wordpress’, ‘jokes’ and ‘mcdonalds’ respectively.
Use the command at your own risk, remember to back up your database properly before you use the function. It works for MySQL.
