sendAndLoad (can send but not load...)

[TheLostGuru]

Ok, well I have spent the last 45 minutes reading old threads about sendAndLoad, but cannot seem to figure it out. I am doing it twice. The first time, I don't really want to sent anything, but only receive a couple variables which I am pullin from a database. The second time, I only send variables and do not receive any. The second time works just fine. Here is the AS code and the PHP code that I use to try and receive variables.

function receiveVariables () {
	var_text.text = "loading";
	varsIn.onLoad = function (success) {
		if(success) {
			background.gotoAndStop(this.color);
			if(!this.owner) {
				save._visible = false;
			}
			var_text.text = this.color;
		}
	}
	varsOut.sendAndLoad("../sendColor.php", varsIn, "POST");
}

mysql_connect($_server,$_user,$_password);
@mysql_select_db($_database) or die( "Unable to select database");
//color will actually retrieve $_frame, but to simplify things I changed it to 1
echo "color=1";
mysql_close(); 

I appreciate any help. This is really getting to me.

At a quick glance I'd say it's 1 of two things:

Either A) You're scope "this.color" is wrong (try absolute of _root.varsIn.color);
or B) You don't seem to be passing a success variable back as true, so it would seem as that the conditional is never going off. Have you tried tracing inside the if(success) conditional?

[TheLostGuru]

Yes, my text_box displays "undefined". Also the absolute path didn't work.

[ImprisonedPride]

I did mean tracing in general, just to see if the conditional is actually passing it's check and executing.

if (success) {
    trace("All's well.");
    ....
}

[TheLostGuru]

Well I can't trace because I am testing it on a server, but I just changed it so the text box didn't look at this.color, but "DO I FREAKING WORK?" and yes it showed up.

[ImprisonedPride]

If that doesn't work, you may need to switch methods. Generally I use loadVariables() for loading, and sendAndLoad for sending. Typically I use this method for game high scores (with the exception of my map editor app), but here's how I run through that. Again, sendAndLoad for sending data, and loadVariables for retrieving data.

function sendScores(userName:String, userScore:Number) {
	var sendScore:LoadVars = new LoadVars();
	sendScore.userName = _root.username;
	sendScore.myScore = _root.score;
	sendScore.table = "table";
	var score_result:LoadVars = new LoadVars();
	score_result.onLoad = function(success:Boolean) {
		if (success) {
		} else {
			trace("Error connecting to server.");
		}
	};
	sendScore.sendAndLoad("someUrlHere"+Math.random(), score_result, "POST");
}
sendScores(_root.username, _root.score);
//...
function getScores() {
	loadVariables("someUrlHere"+Math.random(), scoreboard);
	for (var sc = 1; sc<11; sc++) {
		scoreboard["username"+sc].text = scoreboard["username"+sc];
		scoreboard["score"+sc].text = scoreboard["score"+sc];
	}
}
getScores();

[TheLostGuru]

Nothing... Here's my code

loadVariables("../sendColor.php", varsIn);
background.gotoAndStop(varsIn.b_color);
if(!this.owner) {
	save_mc._visible = false;
}
var_text.text = b_color;

var_text.text still says it is undefined

[edit] Does loadVariables require an "onLoad"?

[hooligan2001]

I think the varsIn function should be declared outside the receiveVariables function.

Heres an example,

//The loaders that will send and retrieve our variables
var sendVars:LoadVars = new LoadVars();
var getVars:LoadVars = new LoadVars();

//Function is called when getVars recieves values from the PHP script 
getVars.onLoad = function(success) {
    if(success) {
         _root.gotoAndStop(this.colour);
        }else{
             trace("ERROR OCCURRED");
        }
}

function receiveVariables () {
    //Declare the variables you wish to send <-- Examples
    sendVars.playername = this.submitscore;
    sendVars.playerscore = this.playername;

    //Send the variables to the PHP script and wait for a reply
    sendVars.sendAndLoad("sendScore.php?c"+new Date().getTime(), getVars);
}

Ok, big changes.

Problem #1
You can't leave mysql_close() if you don't ever connect to the database.

I changed the paths in sendAndLoad from ("../blahblah", varsIn, "POST") to the full path ("http://blahblah", varsIn, "POST") and everything worked like a charm. Now when I load the swf on the web, it goes back to saying that it is undefined. Anyone know why, things would change from running an swf offline and then one embedded online?

[EDIT] I cleared my cache and it works fine. I didn't know that flash wouldn't find the real file and not the one that has been cached...

Problem #1
You can't leave mysql_close() if you don't ever connect to the database.

mysql_connect($_server,$_user,$_password);
@mysql_select_db($_database) or die( "Unable to select database");

But you do? Ow and its a bad habit to use @ before a function call. It escapes any errors. That could be the problem. Its not contecting too the database and you wouldn't know.

[TheLostGuru]

oh... didn't know that. I'm brand new to this PHP stuff. So I shouldn't use "@'s"? Also, problem. Go to http://tlgames.siteburg.com/welcome.htm. Change the color and click save. Now refresh the page. The background is supposed to go back to the color you saved as. However, it won't unless you clear your cache and refresh the page. How do I work around this?

[TheLostGuru]

Nevermind about the last question. I just added a ?no_cache="+Math.random() to the URL's and it seems to work. (thanks to MD )

Thanks for the help hooligan and IP.

[ImprisonedPride]

It might seem obvious, but what does no_cache do? I thought that was the point of adding Math.random() the url, to force the browser to make a new version on every visit.

[hooligan2001]

Yeah your right IP "sendScore.php?c"+new Date().getTime() generates a random number that will never be duplicated so its a new page every time and stops caching. Its the same thing as the no_cache version except Math.random has a very slight chances of creating the same number
