Availability
Flash Player 5; behavior changed in Flash Player 7.
Usage
my_mc.loadVariables("url", variables)
Parameters
url
The absolute or relative URL for the external file that contains the variables to be loaded. If
the SWF file issuing this call is running in a web browser,
url must be in the same domain as the
SWF file; for details, see “Description,” below.
variables An optional parameter specifying an HTTP method for sending variables. The
parameter must be the string
GET or POST. If there are no variables to be sent, omit this parameter.
The
GET method appends the variables to the end of the URL and is used for small numbers of
variables. The
POST method sends the variables in a separate HTTP header and is used for long
strings of variables.
Returns
Nothing.
Description
Method; reads data from an external file and sets the values for variables in my_mc. The external
file can be a text file generated by a CGI script, Active Server Page (ASP), or PHP script and can
contain any number of variables.
This method can also be used to update variables in the active movie clip with new values.
This method requires that the text of the URL be in the standard MIME format: application/x-
www-form-urlencoded (CGI script format).
In SWF files running in a version of the player earlier than Flash Player 7,
url must be in the
same superdomain as the SWF file that is issuing this call. For example, a SWF file at
www.someDomain.com can load variables from a SWF file at store.someDomain.com, because
both files are in the same superdomain of someDomain.com.
In SWF files of any version running in Flash Player 7 or later,
url must be in exactly the same
domain (see “Flash Player security features” on page 188). For example, a SWF file at
www.someDomain.com can load variables only from SWF files that are also at
www.someDomain.com. If you want to load variables from a different domain, you can place a
cross-domain policy file on the server hosting the SWF file that is being accessed. For more
information, see “About allowing cross-domain data loading” on page 190.
