I'm just trying out PHP and AS3 in Flash CS6. I want a few strings to be passed from PHP to Actionscript3 and store them in an array. Is this possible?
Currently I'm doing this. My PHP code is
<?php
echo "one,two,three,four";
?>
and AS3 code is:
var myRequest:URLRequest = new URLRequest("please7.php");
var myLoader:URLLoader = new URLLoader();
myLoader.load(myRequest);
myLoader.dataFormat = URLLoaderDataFormat.TEXT;
myLoader.addEventListener(Event.COMPLETE, onLoaded);
function onLoaded(event:Event):void {
var variables:String = event.target.data;
trace(variables);
var arr1:Array = new Array();
arr1 = variables.split(",");
trace(arr1);
}
This gives me this output:
<?php
echo "one,two,three,four";
?>
If I use myLoader.dataFormat = URLLoaderDataFormat.VARIABLES; instead of myLoader.dataFormat = URLLoaderDataFormat.TEXT; ..I'm getting this error
Error: Error #2101: The String passed to URLVariables.decode() must be
a URL-encoded query string containing name/value pairs.
I want the output to be a simple [one two three four]
What am I doing wrong?
You can do like following, it will be passed as a query-string
In PHP
<?php
echo 'q=' . htmlentities($your_data);
?>
In AS3
var urlLoader:URLurlLoader = new URLurlLoader();
urlLoader.dataFormat = URLurlLoaderDataFormat.VARIABLES;
urlLoader.addEventListener(Event.COMPLETE, onComplete);
urlLoader.load(new URLRequest("somefile.php"));
function onComplete (event:Event):void {
trace (urlLoader.data.q.toString());
}

I'm trying to send data to a PHP file via JSON but i'm getting an error when trying to JSON the data.
I'm pretty sure i'm doing this right. Any suggestions ?
Here's my ActionScript 3 code :
var dataToSend:Array = new Array();
var data:Object = new Object();
data.callFunction = "getQuestion";
data.numberOfQuestions = "1";
dataToSend.push(data);
trace(data);
var variables:URLVariables = new URLVariables();
variables.data = JSON.stringify(dataToSend);
var url:String = "myurl";
var request:URLRequest = new URLRequest(url);
request.method = URLRequestMethod.POST;
request.data = variables;
var loader:URLLoader = new URLLoader();
loader.load(request);
loader.addEventListener(Event.COMPLETE, requestComplete);
And my PHP code :
if $data[ "callfunction" ] = "getQuestion";
{
echo("Sent");
}
Your ActionScript 3 code looks fine but you have some problems in your PHP's one.
Let's see that.
The if statement in PHP is like the AS3's one :
<?php
if( condition )
instruction;
?>
The equality operator is the == and not the assignment one ( = ).
As you have sent your data using the POST method, you can use the PHP's $_POST array to get it.
Then, as you have sent it on JSON format, you can decode it using the decode_json() function in your PHP side.
So your PHP code can be like this for example :
<?php
if(isset($_POST['data']))
{
$data = $_POST['data'];
$json_data = json_decode($data);
if($json_data[0]->callFunction == "getQuestion")
{
echo("Sent");
}
}
?>
Then you can get the response of your PHP script in your AS3 requestComplete function :
function requestComplete(e:Event): void
{
trace(URLLoader(e.target).data); // gives : Sent, for example
}
...
Hope that can help.
I have this flash code. It sends score and username in my game to savescores.php. But I have the error above. I have changed URLLoaderDataForma.VARIABLES to TEXT but still same error occurs. What should i do to fix this problem? Thanks in advance..
private function SendScore(score:int)
{
var variables:URLVariables = new URLVariables();
variables.score = score;
variables.username = username;
var urlloader:URLLoader = new URLLoader();
var urlrequest:URLRequest = new URLRequest('http://localhost:90/savescores.php');
urlrequest.method = URLRequestMethod.POST;
urlrequest.data = variables;
urlloader.dataFormat = URLLoaderDataFormat.TEXT;
urlloader.load(urlrequest);
urlloader.addEventListener(Event.COMPLETE, CompleteHandler, false, 0, true);
urlloader.addEventListener(IOErrorEvent.IO_ERROR , ErrorHandler, false, 0, true);
}
private function CompleteHandler(e:Event)
{
var vars:URLVariables = new URLVariables(e.target.data);
if(vars.success) trace('Saving succeeded');
else ('Saving failed');
}
private function ErrorHandler(e:IOErrorEvent)
{
trace('Error occured');
}
ANSWER: Issue was with PHP
-- You must return a var to AS3 or you will get this error.
I am posting this because unless the viewer reads the comments they will not know what the issue was and a solution. Anil, who asked this question stated it was an issue with the PHP and not as3 but gave no reason as to why. It seems the answer marked correct above is not a sufficient answer because it only suggests a possible solution. Where Anil, admitted it was an issue with the php. I believe this answer is more complete and can help someone who has this same issue.
I had a similar issue. The problem was with the php. Unless you output something back from the php you will get this error.
Flash did not like nothing being returned from php and gave the following error:
Error: Error #2101: The String passed to URLVariables.decode() must be a URL-encoded query string containing name/value pairs.
at Error$/throwError()
at flash.net::URLVariables/decode()

at flash.net::URLLoader/onComplete()
Here was a part of my PHP that did not return anything:
if($ConfirmedEmail=="true")
{
echo "Status=true";
}
if($ConfirmedEmail=="false")
{
echo "Status=false";
}
But if it was neither true/false it would OUTPUT NOTHING. = Flash Does Not Like!
So the PHP code had to be this:
if($ConfirmedEmail=="true")
{
echo "Status=true";
}
else if($ConfirmedEmail=="false")
{
echo "Status=false";
}
else
{
echo "Status=Nada";
}
Here is my AS3 code for you to look at. Hope it helps someone.
public function checkEmail(e:Event = null)
{
var urlreq = new URLRequest("http://www.MyWebsite.com/myScript.php");
urlreq.method = URLRequestMethod.POST;
var urlvars = new URLVariables();
urlvars.userID = Main.userID;
urlreq.data = urlvars;
var loader:URLLoader = new URLLoader(urlreq);
loader.addEventListener(Event.COMPLETE, completed);
loader.dataFormat = URLLoaderDataFormat.VARIABLES;
loader.load(urlreq);
}
public function completed(event:Event):void
{
var variables:URLVariables = new URLVariables(event.target.data);
trace("Email Confirmed: " + variables.Status);
}
I assume that the problem is not with request, but with response handling. You are instantiating vars as URLVariables, but probably e.target.data does not comply with the format expected. Trace e.target.data value to get more information.
I'm trying to pass some variables from php to flash, im using this actionscript code:
public function gameOver(score:Number)
{
totalScore.text = score.toString();
var scriptVars:URLVariables = new URLVariables();
scriptVars.score = score;
var scriptLoader:URLLoader = new URLLoader();
var scriptRequest:URLRequest = new URLRequest("checkScores.php");
scriptRequest.method = URLRequestMethod.POST;
scriptRequest.data = scriptVars;
scriptLoader.load(scriptRequest);
scriptLoader.addEventListener(Event.COMPLETE, handleLoadSuccessful);
scriptLoader.addEventListener(IOErrorEvent.IO_ERROR, handleLoadError);
}
function handleLoadSuccessful(e:Event):void
{
trace("Scores Loaded");
var vars:URLVariables = new URLVariables(e.target.data);
nickname1.text = vars.nickname;
score1.text = vars.score;
}
function handleLoadError($evt:IOErrorEvent):void
{
trace("Load failed.");
nickname1.text ="error";
}
And this php code:
<?php
... some code for the mysql connection and select sentence ...
$topScores = mysqli_query($con, $topScores);
$topScores = mysqli_fetch_array($topScores);
echo "&nickname=$topScores[nickname]&score=$topScores[score]";
?>
both runs without errors, the problem is that what i get on flash aren't the variables values but the name of the variables, in other words what i get on vars.nickname is
$topScores[nickname]
and for vars.score
$topScores[score]
If i run the php alone i get this:
&nickname=jonny&score=100
which are the actual variable values i'm trying to get, any help would be greatly appreciated.
I think you may just be loading up the php file as a text file from flash. Can you change the following line:
new URLRequest("checkScores.php");
to something like:
new URLRequest("http://localhost/checkScores.php");
or whatever you see in the browser address bar when you "run" it as you said in your question.

i have a php script that print with echo this:
'&string="tom,dick,harry"'
and i need to put the "tom,dick,harry" in an actionscript string, that i have to split in an array. I'm having problems reading the php output, i'm using the URLLoader and TheURLVariables Classes in this way
var myRequest:URLRequest = new URLRequest("ip/directory/script.php");
var myLoader:URLLoader = new URLLoader();
function onLoaded(event:Event):void {
var variables:URLVariables = new URLVariables( event.target.data );
modelli = variables.string.split(",");
caricaColori(modelli[0]);
}
myLoader.addEventListener(Event.COMPLETE, onLoaded);
myLoader.dataFormat = URLLoaderDataFormat.VARIABLES;
myLoader.load(myRequest);
What am i doing wrong?
Thought that you got problem with URLVariables, I still not totally understand this yet
function onLoaded(event:Event):void {
var variables:URLVariables = new URLVariables( event.target.data );
modelli = variables.string.split(",");
caricaColori(modelli[0]);
}
why do you need to store it into a URLVariables instance? Why don't parse it directly. If you are afraid of the "&string=", you don't need to echo it on PHP side, or can slice it out on Actionscript side.
modelli = event.target.data.split(",");
Perhaps using a variable name that isn't reserved might help. string seems like a bad choice.
// in php change
echo '&string="tom,dick,harry"'
// to
echo "tom,dick,harry"
// in actionscript change
function onLoaded(event:Event):void {
var str:String = event.target.data;
modelli = str.split(",");
caricaColori(modelli[0]);
}
If you want to add more variables and whatever, I would suggest turning the php response into an xml file. URLVariables should be used to SEND data to the server not for parsing a server response.
LOOK HERE
function onLoaded(event:Event):void {
var variables:URLVariables = new URLVariables( event.target.data );
modelli = variables.string.split(",");
caricaColori(modelli[0]);
}
Your problem is that you're loading the variables into a URLVariables container, and then trying to call a string function on it. I would do it this way instead:
function onLoaded(event:Event):void {
//load data as a string
var variables:String = event.target.data;
//make a new array
var modelli:Array = new Array();
modelli = variables.split(",");
//possibly pop the array
modelli.pop(); //pop off the last empty element of array
caricaColori(modelli[0]);
}
There's also a good chance that when you load this PHP data, you'll need to pop() the last element off of the array because it will be an empty string.
