LoadVars Send, sendAndLoad, Load in AS2

Posted under » Flash on 13 March 2009

One of my favourite uses of flash. These 3 methods could assist you in sending variables and hence interact with server side languages like PHP and ASP.

Send will go the script itself.

sendAndLoad will send the variables over while remaining at the same page.

Load does not send anything but merely receive the variables from a text file.

All three methods have different syntax and will not work if you just change the tag send to tag sendAndLoad.

send

submit_button.onRelease = function(){
submitURL = "login.php";
// create a LoadVars object instance and populate it.
send_lv = new LoadVars();
	send_lv.username = "Robert";
	send_lv.password = "DeNiro";	
//now the magic
	send_lv.send(submitURL, "_self", "POST");
};

Load

submit_button.onRelease = function(){
// Load what?
var result_lv:LoadVars = new LoadVars();
result_lv.onLoad = function(success:Boolean) {
    if (success) {
        result_ta.text = "We are in business.";
    } else {
        result_ta.text = "Error connecting to server.";
    }
 };
//now the magic
my_lv.load("http://www.helpexamples.com/flash/params.txt");
};

Another method to load variables is by using flashvars.

sendAndLoad

submit_button.onRelease = function(){
submitURL = "login.php";
// Load what?
var result_lv:LoadVars = new LoadVars();
result_lv.onLoad = function(success:Boolean) {
    if (success) {
        result_ta.text = "We are in business.";
    } else {
        result_ta.text = "Error connecting to server.";
    }
 };
// send what?
send_lv = new LoadVars();
	send_lv.username = "Robert";
	send_lv.password = "DeNiro";	
//now the magic
	send_lv.sendAndLoad(submitURL, result_lv, "POST");
};
