Passing variables from PHP to Flash

[tox0tes]

Why doesn't this work?

Code in actionscript:

Code: Select all

loadVars.load("upload.php");
_root.imagePane._x+=width1;

Code in PHP file upload.php:

PHP: Select all

echo "width1=50"; 

It doesn't do anything, why not? I want it to create a new variable in the flash file called width1 with value of 50, but it seems this does not happen.

Its not a correct way to pass a variable to flash
You have 2 ways :

1) using flashvars (more info : http://kb.adobe.com/selfservice/view...6417&sliceId=2)
2) put your variable in the html file file like this :

HTML: Select all

<embed src="movie.swf?variablename=something">
<param name=movie value="movie.swf?variablename=something">

the problem is that the user will be on the same HTML page with the same SWF while all this variable passing happens. I cannot use the methods you described because in my situation, where the value of the variable is generated uniquely by the user, i would have to use a PHP page with the value dynamically hardcoded into the HTML as the ?value=whatever or the FLashVars method. But, since PHP is server side, i cannot change the HTML while the user is on the page without refreshing, and that would cause the loss of all the user's color and style selections on the page. remember I am using http://www.momdadsquad.com.

So what I am saying is the variable passing has to happen internally, on the backend without making the user have to go to another page or refresh. Basically, I want the same SWF in the same instance to submit info to a PHP page, PHP to process the info, and then return it to the SWF. I'm sorry it's hard to explain complicated things like this, but thanks for trying to help me.

I think I understand. You want to process information from a SWF to the database using PHP WITHOUT refreshing the current page. I'm no guru, but you're limiting the options and hoping for more capability that Flash or any web page has to offer.

You can process the information using a secondard PHP page. Have Flash send a request to a new window (_blank) with the information you want to pass. That should be simple. The problem you'll run into is Flash CANNOT do anything with the processing. The page is required to do the processing first and forward it to Flash. If you don't want to refresh the page, then you can't update Flash. Using GET and POST, and FLASHVARS are the only three methods Flash has to receive (send) information. If you don't use then you're come up short.

If you are worried about losing the information the user has selected, have Flash send the information to PHP and store it in a cookie. This way it can be retrieved, process and returned to Flash on a refresh. Sorry I could help ya more.

You can definitely do this without refreshing the page...;

WIth actionscript you can use the loadVars class

Code: Select all

var loadExternal = new loadVars(); // instantiate

loadExternal.load('file.php'); // load the php file

Now in your PHP file, you need to send the urlencoded string as plain text

PHP: Select all

header('Content-type: text/plain');



echo urlencode('var1=1&var2=2&var3=3'); 

Once loaded the variable "loadExternal" in actionscript will have properties with the loaded variable names..

eg.

loadExternal.var1 will be 1 etc...

This is the easiest way to do it -- loadvariables has been depreciated in actionscript 2.0
