Validate Email Addresses

[LonelyRoad]

I am trying to validate an email address passed to a function (as shown in the code below) but no matter what I give the function it always returns no match (and the outputchatbox runs twice for some reason).

function validateEmail(email) 
    local email = tostring(email) 
    if (email:match("[A-Za-z0-9%.%%%+%-]+@[A-Za-z0-9%.%%%+%-]+%.%w%w%w?%w?")) then 
        outputChatBox("Match!") 
        return true 
    else 
        outputChatBox("No Match!") 
        return false 
    end 
end 
addCommandHandler("testing", validateEmail)

The first parameter of addCommandHandler is "commandname" for the client side and "playersource" for server side, so use for server side in your function:

validateEmail(_,_,email) 

and for the client:

validateEmail(_,email)

For what reason would the 'No Match!' output twice here now?

If the email matches, it returns true and does the outputchatbox once, but if it's no match it does the outputchatbox twice (and presumably returns false twice, too).

Debug the script, chek what email returns, and the email:match

The :match() part I found on the Lua Docs, I was hoping a copy+paste with a little bit of tweaking would work.

I just tryed it client side. With the command handler ,

"/testing [email protected]" - return one time match in the chatbox.

"/testing asd@yahoo" - return one time no match in the chatbox.

so the function work's well maybe the problem is somewhere else ? you tested it aswell with the CommandHandler ??
