Question

I have this regular expression below to validate a security question where some one has to type in the answer twice. My client want the answers to be none case sensitive. So if someone types in Chester and the in the second field they type in chester it will match. What can I do to this expression to make that happen:

/^(\w|[a-zA-Z\d\s\.\@\-\?\,\&\/\_\#\+\(\)\""\'']){3,50}$/

Answer 1

Simply append the i modifier:

/^(\w|[a-zA-Z\d\s\.\@\-\?\,\&\/\_\#\+\(\)\""\'']){3,50}$/i
