Sending/Receiving Variables between Flash/PHP

5+ Year Member

Msg#: 4057356 posted 3:40 pm on Jan 9, 2010 (gmt 0)

Hi all,

I am quite a newbie at ActionScript and for a class project I am trying to develop a car configurator, this flash app is supposed to be embeded into a web CMS that I have developed in PHP.

But before I even start that, I am trying to understand how Flash can send and receive data to/from php.

My issue is this: the user logs in through my php pages and a number of session variables are set, these contain things such as the username of the user, email, etc...

Now I would like to pass these session variables to Flash.

As far as I understood it, this is how I have to proceed:

1. Use FlashVars to pass the session id of the user during loading of the flash movie/app.

2. The flash movie/app then sends the sessionid to a php script which outputs all session variables of that sessionid.

3. Now the flash movie/app has access to all the session variables.

My problem is that since I am new at ActionScript I am not so familiar with the syntax.

Here is what I have, if someone can point me in the right direction I would really appreciate it:

My embed script which passes the sessiond id as a FlashVars:

<object classid="clsid:(blah)" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,28,0" width="800" height="800" id="ZoomifyHotspotViewer">
<param name="flashvars" value="phpsessionid=<? print session_id(); ?>">
<param name="src" value="test.swf">
<embed flashvars="phpsessionid=<? print session_id(); ?>" src="test.swf" pluginspage="http://www.adobe.com/go/getflashplayer" type="application/x-shockwave-flash" width="800" height="800" name="YourSWF"></embed>

My actionscript which attempts to send the session id to the php (it's not working, I am not sure why):

//send the sessionid to the flash page
send("http://www.example.com/flash.php?sid=" + phpsessionid, "", "POST");

myData = new LoadVars();

myData.onLoad = function(){
placeTheDataIntoTheRightPlace();//call the function that handles the data.


placeTheDataIntoTheRightPlace = function(){

t_username.text = myData.username;


Finally, my flash.php script:

//info for flash

//start the session using the session id passed by the flash movie

//the username
echo '&username='.$_SESSION['username'];
echo '&loggedin='.$_SESSION['logged_in'];


If someone could tell me what I have done wrong I would really appreciate it.

I don't use FlashVars, I use other methods, but here's a couple things I spot right off that may help.

What you are doing here,

<param name="flashvars" value="phpsessionid=<? print session_id(); ?>">

and here, for Moz browsers,

<embed flashvars="phpsessionid=<? print session_id(); ?>"

is passing only the variable "phpsessionid" to your program. So as an experiment, try doing this in your A.S.:

t_username.text = phpsessionid;

and the text field should display the value of phpsessionid.

Without digging through the docs on LoadVars(), I can't tell if your method in flash.php will work or not.

Hi, thanks for your feedback, the problem was that my send() and load() calls were being given seperate session id's by the server. Combining them worked.
