Seach mySQL using flash + PHP

Question

So... I have done my studying... and I can pefectly fine
print data into flash from mySQL.
The problem is, is that I want to create a search in flash,
that sends a variable to php to use in the mySQL query. WITHOUT
opening a new page, and staying in flash.
I can use:
on (release) {
getURL("get_users.php", _blank, "POST");
and it will post my results of my input box into the php file
and print what I tell it to
but when I use:
on (release) {
receiver.onLoad = function(ok) {
if (ok) {
myGrid.removeAllColumns();
myGrid.removeAll();
for (var i = 1; i<=receiver.total; i++) {
receiver["dataPacket"+i] =
receiver["user_data"+(i)].split("|");
var _FirstName:String = receiver["dataPacket"+i][0];
var _LastName:String = receiver["dataPacket"+i][1];
var _Age:String = receiver["dataPacket"+i][2];
myGridArray.push({FirstName:_FirstName, Last:_LastName,
Age:_Age});
delete (receiver["user_data"+i]);
myGrid.dataProvider = myGridArray;
} else {
myGrid.removeAllColumns();
myGrid.removeAll();
myGridArray.push({status:"No data was found!"});
myGrid.dataProvider = gridArray;
sender.sendAndLoad("get_users.php",receiver,"post");
To try and print the results in flash.. I get screwed and my
grid.
I believe it is because the PHP file is not reading my POST
from my input test and using it in the query.
here is what my PHP query looks like:
$query = @mysql_query("SELECT * FROM $tableName WHERE
FirstName=
'$_POST[search]' ORDER BY
FirstName");
but if I put in "FirstName='$search'"
and I put in elsewhere $search = "Levi"
then it finds levi and prints it to the flash file.
I"M SO FRUSTRAITED! haha, i'm so close
It's like flash can't do two things at once. (send AND
receive)
anybody ever done this before? I could really use the advice.
do I use a "while" condition in flash? or something? I don't
know.

Flash can send and receive from a PHP script.
1. You need to attach the variables to the send LoadVars
variable.
sender.search = expression.
Probably in your case you have a timeline variable also named
seach that getURL automatically sends. So you might need to
sender.search = search;
2. Either drop the last argument or capitalized as noted in
documentation. sender.sendAndLoad("get_users.php", receiver,
"POST"); Default is POST if you leave it off.
3. Be sure PHP script functions correctly. Create a standard
HTML form to send the data to your PHP script and look at the
output. That output is what Flash received in the return LoadVars
object as your code appears to be trying to pickup. But be sure by
looking at it.
You also could loop using for(key in receiver) to trace the
variables to verify what you are receiving instead of creating an
HTML test form.
Be sure to also trace the ok argument in receiver.onLoad.
4. Look at strict typing all variables.
reciever.onLoad = function(ok:Boolean) for example.
