Email Validator in Form

[oahu9872]

I would like to require valid email addresses in my form, making sure that there is the @ symbol somewhere in the field. Does anyone know the code to do this? Is it ASP or HTML?

Thanks

If InStr(strEmail, "@") Then

if your addresses are internal ones then you could also check Exchange to see if they are 'real'.

I would recommend using a regex with this pattern:

oRE.Pattern ="^[\w-\.]{1,}\@([\da-zA-Z-]{1,}\.){1,}[\da-zA-Z-]{2,3}$"

This is what I used, and it works well.



Dim EmailAtCheck
Dim strEmail : strEmail = Request.QueryString("Email")
If InStr(strEmail, "@") Then
EmailAtCheck = "TRUE"
else
EmailAtCheck = "FALSE"
end if

What if someone enters

@somewhere

as their email address? Or simply enters @?
