I have a page where the user enters an email address. What code would I use to make sure the email address is in a valid format? I don't need to verify it. I just want to make sure they enter something like abc@abc.com. If they don't then I want them to receive an error about the email not being valid and to go back and enter a valid one.<

I seem to remember there was a ChkEMail function (or something similar) in inc_func_common.asp. It would be a good place to start...<

AnonJr: I have had a look through inc_func_common and can not see an email validity check routine. Like you say, I am sure there is a routine, somewhere within the forum, to meet leatherlips requirement. Any further ideas please..<

Posted sometime ago as a security fix replacement for an existing function in inc_func_member.asp:

Code:


function EmailField(fTestString) 
	set regEx = New RegExp
	regEx.Global = true
	regEx.IgnoreCase = true
	regEx.Pattern = "^[A-Z0-9._%-]+@(?:[A-Z0-9-]+\.)+[A-Z]{2,4}$"

	retVal = regEx.Test(fTestString)

	set regEx = nothing

	if Not retVal Then
           EmailField = 0
	Else
           EmailField = 1
	end if
end function
