424 Chapter 12: ActionScript Dictionary
level An integer specifying the level in Flash Player to receive the variables.
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
Function; reads data from an external file, such as a text file or text generated by a CGI script,
Active Server Pages (ASP), PHP, or 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-form-
urlencoded (a standard format used by CGI scripts). Any number of variables can be specified. For
example, the following phrase defines several variables:
company=Macromedia&address=600+Townsend&city=San+Francisco&zip=94103
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.
If you want to load variables into a target MovieClip, use
loadVariables() instead of
loadVariablesNum().
Example
This example loads information from a text file into text fields in the main Timeline of the SWF
at level 0 in Flash Player. The variable names of the text fields must match the variable names in
the data.txt file.
on(release) {
loadVariablesNum("data.txt", 0);
}
