Loadvariablesnum Function - MACROMEDIA FLASH 8-ACTIONSCRIPT 2.0 LANGUAGE Reference

loadVariablesNum function

loadVariablesNum(url:String, level:Number, [method:String]) : Void
Reads data from an external file, such as a text file or text generated by ColdFusion, a CGI
script, ASP, PHP, or a Perl script, and sets the values for variables in a Flash Player level. You
can also use this function to update variables in the active SWF file with new values.
The text at the specified URL must be in the standard MIME format
application/x-www-
(a standard format used by CGI scripts). Any number of variables can be
form-urlencoded
specified. For example, the following phrase defines several variables:
company=Macromedia&address=601+Townsend&city=San+Francisco&zip=94103
In SWF files running in a version of the player earlier than Flash Player 7, must be in the
url
same superdomain as the SWF file that is issuing this call. A superdomain is derived by
removing the leftmost component of a file's URL. For example, a SWF file at
www.someDomain.com can load data from a source 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, must be in exactly the same
url
domain as the SWF file that is issuing this call (see "Flash Player security features" in Using
ActionScript in Flash). For example, a SWF file at www.someDomain.com can load data only
from sources that are also at www.someDomain.com. If you want to load data from a different
domain, you can place a cross-domain policy file on the server hosting the SWF file. For more
information, see "About allowing cross-domain data loading" in Using ActionScript in Flash.
If you want to load variables into a target MovieClip, use instead of
loadVariables()
.

POST
long strings of variables.
