Phone Number Validation Function

[Stephen MacLean]

Hi Bob,

Last year I released a sample library for base functions like this:

https://github.com/renegadesteve/rsIsValid <https://github.com/renegadesteve/rsIsValid>

You can use the LCS version, or build a widget library for your version of LC 9.

It does use RegEx, but you can Sean said, there are many ways to do what you are looking to do.

Since it seems that you are looking for consistency across you app, however you get there, it can be done in multiple ways. RegEx is a valid way to do.

As always, YMMV.

Best,

Steve MacLean

That means that while certain numbers are acceptably formatted phone numbers according to some international standard, having +1 at the beginning for example, I don't necessarily want that. Periods are valid delimiters, but I don't want that either.
