I apologize if this has been asked, but I couldn't find anything in a forum search.
Is there a way to validate a phone number? I have been doing the ff_valuenotempty, but it will accept anything someone puts there. Is there a way to see if its a number?
I think the easiest way would be to check that it is the appropriate number of digits, with no spaces, but I understand the integer validation only checks to see if its an integer, not one of a specific length.
Any thoughts?
