Preg match email

[petenaylor]

Hi all

 

I am trying to do an email validation check. Here's my code:

 

if (!preg_match($email) == "^[a-z0-9]+([-_\.]?[a-z0-9])+@[a-z0-9]+([-_\.]?[a-z0-9])+\.[a-z]")

{

include("checkout-email-error.php");

exit;

}

 

 

It doesn't seem to allow any email addresses through? All help greatly appreciated!

 

Thanks

Pete

Check the PHP manual page for preg_match, which will tell you how to properly use that function.

See http://php.net/preg_match

I have found this useful for this, it negates the need for doing preg_match() on a $var:-

 

if(!filter_var($input, FILTER_VALIDATE_EMAIL)){
echo "Email is not valid";
        exit;
}

 

Kinda cool if your not much good at regex!

 

But if you want your preg_match() in there, use this:-

 

if (!preg_match("/^([a-z]|[0-9]|\.|-|_)+@([a-z]|[0-9]|\.|-|_)+\.([a-z]|[0-9]){2,4}$/i", $input)){
echo "Email isn't valid";
        exit;
}
