Email address validation

Is there a way to force an email address field to force it to have a "valid" email address makeup?  I realize I can't actually validate the email address itself, but I want to require them to at least put in an email address in a valid format?  (I have seen this on multiple forms across the internet, of course.)

  • There is not a built in function for this, but some of us have formulas squirreled away to do our own validation.  try this one

    var text email = Trim([My Email Field]); 

    // you will need to decide what to do about leading and trailing spaces.  This tends to happen with copy paste by users.  probably best to treat the field as raw input and use Trim([MyField] )  for all subsequent use of the data entry field. 

    var text Warning =If($email="", "Missing email address",

    List( "<br>",
    //If( begins($email," "), "Leading space character" ), // should not be necessary if TRIMed
    //If( ends  ($email," "), "Trailing space character" ), // should not be necessary if TRIMed
    If( not Contains($email,"@"), "Missing @ symbol" ),
    If( not Contains(Part($email, 2, "@" ),"."), "Missing .com or similar at the end" ),
    If( Contains($email, " "), "Has a space inside the email address" ),
    If(Part($email, 1,"<>[]{},")<>"", "Bad characters in in the email address"),
    If(Part($email, 2,"<>[]{},")<>"", "Bad characters in in the email address"),
    If(Begins($email,"<"), "Bad characters in email address"),
    If(Ends($email,">"), "Bad characters in email address"),
    If(Contains($email, "mailto"), "Bad email address"),
    If(Contains($email, ":"), "Bad email address" ),
    If(Ends($email, "."), "email ends in a period - that can't be right" ),
    If(contains($email, ")"), "email contains a bracket ( or ) - that can't be right",

    If(contains($email, "("), "email contains a bracket ( or ) - that can't be right" )


    If($Warning<>"", "<font color=red>" & $Warning)

      I'm going to have to add this to our contacts table as a custom data rule.

        There is also a simple checkbox in the QB Exchange that checks for email validity for anyone that goes in there often
