What you’ll learn:

You’ll learn how to pass variables from the URL into Flash, using SWFObject and FlashVars.

Scenario:

Recently I’ve had to develop an application that would allow the users to create a sports card with their photo, name and favourite number on it.

This application had a form outside of Flash and my task was to integrate the Flash application which was on a page whose URL was something like:

http://www.mydomain.com/?firstname=john&lastname=doe&number=55

that was generated by the form.

This means that we have three variables:
firstname, lastname and number, with the values of john, doe and 55 respectively.

These are the variables we're interesting in and have to make available to Flash.
