Shared local objects

When I read Advanced PHP for Flash, I was first introduced to local shared objects in Flash and have been in love with them ever since. Last night I set up a shared local object for my electronic music quiz to give users the option of remembering their login information. It is very, very simple to do this. During login state initialization, I have this code:

login_so = SharedObject.getLocal('quizLogin');
if (login_so.data.username != undefined) {
username_txt.text = login_so.data.username;
password_txt.text = login_so.data.password;
}


First, I access the shared object ("so"), whether it already exists or not. If the so's data contains a variable named username, I fill in the username and password information that has been stored previously on the user's machine.
At login, I store in the so the username and password the user entered to be accessed the next time the user visits. This is done like so:

login_so = SharedObject.getLocal('quizLogin');
login_so.data.username = username_txt.text;
login_so.data.pass = password_txt.text;
login_so.flush();

And that's it! You might want to put in some conditionals and let the user decide whether to save the login data to a shared object or not. But the shared object code alone really is that simple.

My friend Starrie had the great idea to greet my site visitors with updates on what I am up to professionally. Enter MediaSparkles version 3.0. I have set up a mini blog to which I will post projects I am working on and my thoughts on Flash and related technologies. If you're looking for the old cubes and bubbles that used to live here, they have moved here.
