Rewriting the sendemail() Function

Now it ’ s time to rewrite the sendemail() function you wrote above. You have three possible outcomes,

in order of simplicity:

There are no POST data — If so, simply send the user to the admin_subs_mail view, so she can

compose a message.

There are POST data, and the test flag is TRUE — In this case, simply send the composed

message to the test recipient (in your case, Claudia).

There are POST data, and the test flag is FALSE — In this case, extract the subscribers from the

database using the getAllSubscribers() function of MSubscribers, and then send the

message to those subscribers.

The way this three - part logic tree manifests itself is as an if-else condition, with the first if branch (POST

data exist) having its own if - else branch (is this a test message?) embedded in it.

It ’ s almost as complicated talking about it as seeing it in action, so without further ado, here ’ s the code.
