loadVariablesNum() 423

Description

Function; reads data from an external file, such as a text file or text generated by a CGI script,

Active Server Pages (ASP), or PHP, or Perl script, and sets the values for variables in a target movie

clip. This action can also be used 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 specific level, use

loadVariablesNum() instead of

loadVariables().

Example

This example loads information from a text file into text fields into the varTarget movie clip on

the main Timeline. The variable names of the text fields must match the variable names in the

data.txt file.

on(release) {

loadVariables("data.txt", "_root.varTarget");

}
