Preg_match

[xyn]

Hii

Does anyone know how to make my code correct so an e-mail MUST be filled in correctly:

[code]$email = $_POST['mail'];
if( !preg_match("/[A-Za-z0-9\._%-]+\@[A-Za-z0-9\._%-]+/", $email)){
die('error');
}
[/code]

I suggest looking into the PEAR package, Validator - or something like that. I use it to verify emails and it works like a charm. Even if you don't want the extra code, it is worth checking out to see what regular expression they use.

I took a 2nd glance and realised i forgotte to put the .com // .co.uk etc. part so it should have looked like:

[code]
$mail = $_POST['mail'];
if( !preg_match("/[A-Za-z0-9\._%-]+\@[A-Za-z0-9\._%-]+.[A-Za-z0-9\]/", $mail)){
die('error: no email');
}
[/code]

about the best email validation i've found is this:
[code]
preg_match('|^[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$|i', $email);
[/code]

the only things you're really missing is the '^' at the beginning and the '$' at the end to make sure that nothing funky has been going on in front or behind it.
