I have a custom field on a post named town and I fill it in with the town name and use that in various places on the page. So for example it could be London and I need the capital letter as that’s how it should be displayed on the page but when I create a link that goes to https://mydomain.com/London/ it’s no good as I need it to point to https://mydomain.com/london/ so I want to convert the contents of the custom field to lower case before appending it to an oxygen buttons url
Please provide the code you are using to display the content of this field.
