loadVariablesNum function -- Version 8

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-form-urlencoded(a standard format used by CGI scripts). Any number of variables can be specified. For example, the following phrase defines several variables:

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. 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, url must be in exactly the same 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 loadVariables() instead of loadVariablesNum().

Availability: ActionScript 1.0; Flash Player 4 - Behavior changed in Flash Player 7. Flash 4 files opened in Flash 5 or later are converted to use the correct syntax.

Parameters

url:String - An absolute or relative URL where the variables are located. 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 the Description section.

level:Number - An integer specifying the level in Flash Player to receive the variables.

method:String [optional] - Specifies 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.

Example

The following example loads information from a text file called params.txt into the main Timeline of the SWF at level 2 in Flash Player. The variable names of the text fields must match the variable names in the params.txt file. The setInterval() function is used to check the progress of the data being loaded into the SWF. The script checks for a variable in the params.txt file named done.

loadVariablesNum("params.txt", 2);
function checkParamsLoaded() {
 if (_level2.done == undefined) {
 trace("not yet.");
 } else {
 trace("finished loading. killing interval.");
 trace("-------------");
 for (i in _level2) {
 trace(i+": "+_level2[i]);
 }
 trace("-------------");
 clearInterval(param_interval);
 }
}
var param_interval:Number = setInterval(checkParamsLoaded, 100);

// Params.txt includes the following text
var1="hello"&var2="goodbye"&done="done"
