Flash: XML and LoadVars to send data in POST

Here is a great way to send POST data to a Web Server. We will use two objects: a LoadVars object to send and to receive an XML object (in case we expect a return formatted XML document). Use the LoadVars object in Flash is useful for creating run-time properties that will be seen as POST variables for both the ability to specify the delivery method: POST or GET.

First of all we create the LoadVars object that will be used to ship:

1	LoadVars = new LoadVars ( ) ; var s_lv: LoadVars = new LoadVars ();

To this we add the POST variables in a very simple:

1 2	; s_lv. title = "Hello"; ; s_lv. subtitle = "Hello World";

Prepare the object that receives the response from the Web Server (in stdout) - if you just make a PHP echo:

1 2	XML = new XML ( ) ; var r_xml: XML = new XML (); = true ; r_xml. ignoreWhite = true;

At this point we can do is send:

1	"http://miodominio.com/miapagina.php" , r_xml , "POST" ) ; s_lv. sendAndLoad ("http://miodominio.com/miapagina.php" r_xml, "POST");

The sendAndLoad () method of the LoadVars object is very ultile as it allows you to specify the object return (in this case our XML object r_xml) and the shipping method (in our case POST).
Finally just put on hold:
