Delete a data of my database from AS3 - php

Question

I'm trying to delete a data from my database with ActionScript 3.
I've created a php on my server :
<?php
include ("shared/connect.php");
$idToDelete = $_POST['idToDelete'];
$result = mysqli_query($conn,"
DELETE FROM `annoncesNew` WHERE id=$idToDelete");
?>
Then I have to send the variable idToDelete to this php in order to delete the entry.
So I did :
deleteBtn.addEventListener(MouseEvent.CLICK, deleteThisAnnonce);
function deleteThisAnnonce(event:MouseEvent):void {
trace("deleteThisAnnonce");
var variablesDelete:URLVariables = new URLVariables();
var varDelete:URLRequest = new URLRequest("http://www.***com/***/deleteAnnonce.php");
varDelete.method=URLRequestMethod.POST;
varDelete.data=variablesDelete;
var varLoaderDelete:URLLoader = new URLLoader;
varLoaderDelete.dataFormat=URLLoaderDataFormat.VARIABLES;
varLoaderDelete.addEventListener(Event.COMPLETE,completeHandlerDelete);
ValidateAndSendDelete();
function completeHandlerDelete(event:Event):void{
trace("Data Sent");
}
function ValidateAndSendDelete():void{
trace("deleting"+item.id); //item.id is my the ID. When I trace the output is 144 so it's good.
variablesDelete.idToDelete = item.id;
varLoaderDelete.load(varDelete);
}
}
So, with this code, it's supposed to delete the data where id = 144. But I've got this error when click on the deleteBtn : Error: Error #2101: The String passed to URLVariables.decode() must be a URL-encoded query string containing name/value pairs..
(all the traces are working correctly but my data isn't delete).
I've tried my php by changing DELETE FROMannoncesNew WHERE id=$idToDelete");withDELETE FROM annoncesNew WHERE id=144"); and execute it on my webbrowser and it worked (the line with the id 144 was deleted).
Weirdly, the line is delete with my AS3 code (so the code is working) but it throws this error 2101 anyway. Any idea why ?
Thx

I believe the problem is not in your AS3 code but that your PHP script is not returning any values back to Flash. Try to add this to your PHP script:
echo "Status=true";
And you might need this in your AS3:
varLoaderDelete.dataFormat = URLLoaderDataFormat.TEXT;
