I am using the WebORB for PHP on my server side.
There am doing a SELECT * query and am sending the returned results to Flex.
"How did you create the collection? Did you
use AMF? Did you load from XML?"
I am using the RemoteObjects in here and configured the VO's at both ends.
"Somehow the objects that got created did not
get created as the proper UserVO objects. So check the collection when it
gets set, it's not getting set right. If you're using AMF then you might
need to include a reference to the UserVO class so the compiler knows to
include it, otherwise it won't get deserialized right."
Am new with PHP stuff, so just experimenting with it to use with Flex.
Here is how my class looks like in php:
<?php
require_once("vo/UserVO.php");
class UserDelegate
{
public function getUsers()
{
$link = mysql_connect("localhost", "dbuser", "dbpassword");
mysql_select_db('userdb', $link);
$result = mysql_query("SELECT * FROM tbl_user order by
userId;")or
die("Invalid query: " . mysql_error());
mysql_close($link);
return $result;
}
}
?>
So, I am selecting * and returning $result straightforward, in responder(on
flex side) am getting this in my arraycollection as below:
public function result(data:Object):void
{
//TODO: implement function
var list:ArrayCollection = new ArrayCollection(data.result as Array);
// definition of ALL_USERS - public static var ALL_USERS :
ICollectionView;
ModelLocator.ALL_USERS = list; // $results is being populated to
this corresponding collection.
}
So, on PHP side, am not sure how I would get the result in the form of
UserVO and populate the $result with vo's and then send it back to Flex.
Thanks for your help.
