Jquery serialize and passing in other custom post data - php

Question

function DoAjax( args )
{
var formData = "?" + $("form[name=" + args.formName + "]").serialize();
$.ajax({
type: "POST",
url: args.url + formData,
data: {
request: args.request
},
success: function (data) {
alert(data);
args.callback.html(data);
},
error: function (a, b, c) {
alert("error: " + a + ", " + b + ", " + c + ".");
}
});
return false;
}
I need to pass in a custom bit of data to my php script called "request" which will denote which process to run on the php page... but I also want to serialize any other form fields on my form. Is this the correct way of doing it (add the serialize to the end of the URL) because I just cannot seem to get anything from my PHP $_POST["whatever"]
EDIT:::///
<?php
$request = $_POST[ "request" ];
if( isset( $request ) )
{
require_once( "includes.php" );
function LogInWithClientCred()
{
$username = CheckIsset( "username" );
$password = CheckIsset( "password" );
echo $_REQUEST["username"];
echo $_GET["username"]; // echos correctly the username.. but I want it to be post data instead!
Please ignore the security awesomeness, it is pseudo for your purpose.

Answer 1

Combine formData and your additional data into one string.
var formData = $("form[name=" + args.formName + "]").serialize() + "&request=" + args.request;
$.ajax({
url: args.url,
data: formData,
type: "POST",
...
})

Answer 2

I am not too sure If i got ur question well, But I think you are appending the form data to URL and using POST in ajax.
Can you try
$_REQUEST["whatever"] to see what you are getting
EDIT
After seeing the commnets I think I now got it
function DoAjax( args )
{
var formData = $("form[name=" + args.formName + "]").serialize();
$.ajax({
type: "POST",
url: args.url,
data: {
request: args.request,
formData:formData
},
success: function (data) {
alert(data);
args.callback.html(data);
},
error: function (a, b, c) {
alert("error: " + a + ", " + b + ", " + c + ".");
}
});
return false;
}
Now $_POST[formData] should work
