The E - mail class is very simple: it allows you to quickly and easily send e - mails without too much fuss.
Since you ' re autoloading the class, there ' s no need to invoke it specifically.
First you run
$this-
>
email-
>
clear()
to clear out any settings or variables. You set the " from "
address with
$this-
>
email-
>
from()
, the " to " address with
$this-
>
email-
>
to()
, and so on. Once
you ' ve set the subject and message parameters, you can send with
$this-
>
email-
>
send()
.
The only thing you ' re doing differently is checking for a test message. If the user has indicated a test
message, then send to a single test address. Otherwise, loop through all the subscribers pulled from the
database table, adding an unsubscribe method to the end of the message.
Unsubscribing from within an E - mail
Notice that the last thing you ' re appending to the e - mail is a line of HTML:
$unsub = "
<
p
>
<
a href='". base_url()."welcome/unsubscribe/"
.$list[`id']. "'
>
Unsubscribe
<
/a
>
<
/p
>
";
