You want to load variables into a Flash movie from a server-side script (ColdFusion, Perl, PHP, etc.).
The ActionScript to load variables from a server-side script is
exactly the same as that used to load variables from a text file.
When you call the
load( ) method you should pass
it the URL of the script from which you want to load the variables,
then handle the results with an
method, as shown in Recipe 18.1.
You should use server-side scripts as the source for variables loaded into Flash when the values for the variables are generated from a database or another resource accessible only to the server. The script that you use must output URL-encoded data only, beginning from the first character. If you are writing a CGI script in Perl, the result is URL-encoded, so you do not need to make any special adjustments. For example:
#!/usr/bin/perl # In a more practical example this value would be retrieved # from a database or other server-side resource. $myVar = "test"; # Define the Content-Type header. print "Content-Type: text/plain\n\n"; # Output the name-value pair. print "myVar=$myVar";
However, when you use a ColdFusion page to load variables into Flash, you need to take steps to ensure that it outputs URL-encoded data and that the output begins from the first character. Otherwise, extra whitespace characters may precede the output of the URL-encoded data, in ...
