Flash and PHP - send vars then retreive 3

[martinb7]

Hi, i was wondering how you would send some vars to a php page from flash, the php does something, then flash retrevies the answer??

like a calculator for instance.

i dont know where to go!!

:hp code::

<?php
//calc test
$n1 = $HTTP_POST_VARS[num1];
$n2 = $HTTP_POST_VARS[num2];

$res = $n1 + n2;

echo &quot;&res=&quot;.$res;
?>

flash .fla

im stuck

PS, whats the difference between print & echo?

and whats printf and the like do??




Thanx

Martin

If you use the sendAndLoad() method of the loadVars object you'll get what you need:

sendInfo = new LoadVars();//object to send data
receiveInfo = new LoadVars();//object to receive returned data
receiveInfo.onLoad=function(){//function to work with returned data
	trace(this.res);//show answer
	}
sendInfo.num1 = 10;//set up values to send out sendInfo.num2 = 12;//(can be done with variables but hard coded here)

sendInfo.sendAndLoad('php/doStuff.php', receiveInfo, "POST");//send to script

...as far as Flash is concerned print and echo are the same thing: print is a function and returns a value within PHP while echo doesn't, it merely outputs a value - echo is slightly faster than print.

printf is used to format output, according to rules you build into the statement:

printf ( string format [, mixed args])

Missed a line break above after a comment, here's the code alone:

sendInfo = new LoadVars();
receiveInfo = new LoadVars();
receiveInfo.onLoad=function(){
	trace(this.result);
	}
sendInfo.value1 = 10;
sendInfo.value2 = 12;
sendInfo.sendAndLoad('php/doStuff.php', receiveInfo, "POST");

I'm learning flash and I have a project i'm developing whereby the end-user will need to refresh data from time to time to be displayed within a Flash site. They will be posting updatable press releases sourced from some kinda database. I was advised by a different expert xml is the way to go. I have no idea how to code or enact xml to nest into a flash page. Can Flash handle this alone w/o programming in another language? If so, what's the ActionScript to enable this? Thanks is advance!

XML is suported by flash as i'm aware from v.5.0

this was tested with MX 2004
[code]
the text.xml file had only this line
<XML prop1=&quot;test&quot; prop2=&quot;100&quot;/>
you can send all the data you need from the server as the properties to 1 XML record and use it's firstChild to access them

var x=new XML()
x.onLoad = function (success)
{
	trace(&quot;loaded &quot;+success)
	for(i in this.firstChild.attributes) trace(this.firstChild.attributes[i])
        //or access the attributes directly
        trace(this.firstChild.attributes[&quot;prop1&quot;])
        trace(this.firstChild.attributes[&quot;prop2&quot;])
        //etc
}
x.load(&quot;test.xml&quot;);
