Unable to get return value from PHP

[supriyaakg]

Hi,

I am unable to get the data from the php using AS 2.0/FL 3.0 code.

The AS code reads as:


result_lv = new LoadVars();
result_lv.num1 = 12;
result_lv.num2 = 34;

result_lv.onLoad = function (success)
{
if (success)
{
trace("Return value from the PHP : " + unescape(this));
}
else
{
trace("Cannot call the PHP file...");
}
}
result_lv.sendAndLoad("addPHP.php", result_lv, "POST");


And the 'addPHP.php' contains:

<?php
$fVar1 = $_POST['num1'];
$fVar2 = $_POST['num2'];
$rtnValue = $fVar1 + $fVar2;
echo $rtnValue;
?>

I get the following as output when I trace the return from php using 'trace("Return value from the PHP : " + unescape(this));':

Return value from the PHP : <?php

$fVar1 = $_POST['num1'];

$fVar2 = $_POST['num2'];

$rtnValue = $fVar1 $fVar2;

echo "supriya";

?>&onLoad=[type Function]&num2=34&num1=12

Though, everthing is fine with the php. I am able to see the execution through the web browser.

I think you will have to host the PHP on a web server to make it work. You will have to specify the complete URL.

Hi Ramesh,

Thanks for your help. The same advice is advocated in http://www.sephiroth.it/tutorials/flashPHP/loadVars/.
I did get the result this time, but also accompanied by '&onLoad=[type Function]&num2=34&num1=12'. How do I suppress this?

Ciao,

you need to define a data to be sent and data to be received. You defined the same object to do both!

You have this code:
result_lv = new LoadVars();

result_lv.sendAndLoad("addPHP.php", result_lv, "POST");

You should define the data to be sent and object data that receives data from your server:

data_lv = new LoadVars();
data_lv.num1 = 12;
data_lv.num2 = 34;
data_lv.sendAndLoad("addPHP.php", result_lv, "POST");

Also the PHP script needs to have the link to the server http://yourserver.com/addPHP.php

Hi Alessandro,

Even with the following code, apart from the result value echoed from the php, I also get the following:

key 90 =
key onLoad = [type Function]

AS code:

result_lv = new LoadVars();
data_lv = new LoadVars();
result_lv.num1 = 34;
result_lv.num2 = 56;

data_lv.onLoad = function (success)
{
if (success)
{
for( var prop in this )
{
trace (" key " + prop + " = " + this[prop]);
}
}
else
{
trace("Cannot call the PHP file...");
}
}

result_lv.sendAndLoad("http://localhost/PhpProject1/index.php", data_lv, "POST");


PHP code:

<?php
$fVar1 = $_POST['num1'];
$fVar2 = $_POST['num2'];
$rtnValue = $fVar1 + $fVar2;
echo $rtnValue;
?>


How can I only extract in the AS, the value that is echoed from the PHP?

Ciao,

first I suggest you to review AS from the Adobe documentation since you are mixing up your code!

Try this:

result_lv = new LoadVars();
data_lv = new LoadVars();
data_lv.num1 = 34;
data_lv.num2 = 56;

result_lv.onLoad = function (success)
{
if (success)
{
for( var prop in this )
{
trace (" key " + prop + " = " + this[prop]);
}
}
else
{
trace("Cannot call the PHP file...");
}
}

data_lv.sendAndLoad("http://localhost/PhpProject1/index.php", result_lv, "POST");

hi,

The following worked:

result_lv = new LoadVars();
data_lv = new LoadVars();
data_lv.num1 = 34;
data_lv.num2 = 56;

result_lv.onLoad = function (success)
{
trace(unescape(this));
if (success)
{
for( var prop in this )
{
trace (" key " + prop + " = " + this[prop]);
}
}
else
{
trace("Cannot call the PHP file...");
}
}

//the object in the onData function receives all the value echoed by the PHP
result_lv.onData = function(dataReceived)
{
trace(dataReceived);
}

data_lv.sendAndLoad("http://localhost/PhpProject1/index.php", result_lv, "POST");
