Complete Validation for U.S. Phone Numbers

This is what I changed to validate phone numbers.

search for the validateObject.type.indexOf("IsPhoneNumber") in the generated validate.php and modify the snippet.

Test it out and if it all works for you, place this snippet in the validate.php file in the source folder of your templates.

PS. This is version 3.0 im using this in. I modified the IsZipCode also for 5 or 9 zips and the canadian postal code format.
else if(validateObject.type.indexOf("IsPhoneNumber")>=0)

//IsPhoneNumber tells whether the field is a Phone number or not

//These Phone number fields are valid if there is nothing in the field

{

var phone2 = /^\s*([( ]{1}[0-9]{3}[) ]{1}[. -]{0,1}|[0-9]{3}[- .])?[0-9]{3}[- .]{1}[0-9]{4}$/;
if (isWhitespace(validateObject.val)!=true)

{
str = "";

str = removeSpaces(validateObject.val);

if (!str.match(phone2))

{

errors += validateObject.HTMLname + "\n";

PhnMsg += validateObject.HTMLname + " formats: (555) 321-1234, 555-321-1234, 321-1234 (Period separator allowed)"+"\n";

}

}
