a regex string to totally check emails is like a bottomless bottle... it always can be improved to include some other characters, it never is gonna be perfect.. xD

anyway, lasttime i tried, it was in PHP (as thats what i am doing) and i used this lines:

CODE

$len = strlen($email);
if($len < 5 || $len > 50 || !preg_match("/[\.a-z0-9_-]+@[a-z0-9-.]{2,}\.[a-z]{2,4}$/i",$email))
  $err[] = "register_email_invalid";

how to check in php is no problem.
in the guild system is a similary check for special character with regex.
it´s like in php so I tried your code in the sphere language but without success.

so it must be...
maybe sugarcube knows the answer?!?

STRREGEX uses regular expressions. Like you would do with STRMATCH but using regular expresions.
Amadox just gave you the pattern he uses in PHP, it may work in Sphere too.

You can use STRMATCH("*@*.*","<ARGS>"), or STRREGEX

as far as i can see, the sphere thingy doesn't use those / at the beginning and the end, and after taking a closer look at that stuff i posted, i am not sure if that really worked exactly that way.


try those:

CODE

STRREGEX("^[\.a-zA-Z0-9_-]+@[a-zA-Z0-9-\.]{2,}\.[a-zA-Z]{2,4}$","<args>")

CODE

STRREGEX("^[\.a-zA-Z0-9_-]+@[a-zA-Z0-9-\.]+[a-zA-Z]+$","<args>")

CODE

STRREGEX("^[\.a-zA-Z0-9_-]+@[a-zA-Z0-9-\.]+$","<args>")

first one should be the best (most correct) choice, if it works.

anyway, i'm curious: may i ask what you are doing, that needs email validation ingame?
you may answer via pm in german if you like (IMG:style_emoticons/default/wink.gif)

You can use STRMATCH("*@*.*","<ARGS>"), or STRREGEX

Yes, that´s the easiest way and it works.
Thanks Coruja747


Amadox, I need it for my Guild System.
The Guildmaster can save his email on the Guildstone and it will also be saved on my sql server

This is the code I have always used to validate E-mails.

[FUNCTION INVALID.email]
IF (STRMATCH(*[^a-z0-9_.-@]*,<ARGS>))
RETURN 1
ELSEIF (!STRMATCH(*?@?*.?*,<ARGS>))
RETURN 1
ELSE
RETURN 0
ENDIF
