How do I create regular expression of only “a-z”, “0-9”, “-“, “_” and “.”
Hello!
I’m creating a BuddyBoss sign on page with a “nickname” field. BuddyBoss requires only the following characters for the “nickname” field:
“a-z”, “0-9”, “-“, “_” and “.”
How can I create a regular expression for this?
Any other characters need to be excluded.
(Please note, the “a-z” can be upper or lower case.)
Thank you for your help!
