yeah, the other method of passing data via ajax is:
...
url: "myurl.php",
type: "post",
data: {"variablename":"value", "variablename2":someJSValue},
...
you could declare an object that contains your arguments that you want to pass in to updatesql.php like this:
var args = {}
<a href="http://args.name">args.name</a> = "John"
args.location = "Brisbane"
args.SomeOtherVariable = someJSVariable
then you could do:
...
url: "myurl.php",
type: "post",
data: args,
...
where args is the object that you just created.
Hope this helps! :o)

Hi Scott,
The hash was a suggestion on another site. I have tried it without it as
well but no joy. If I alert the "serial" on success I get what I would
expect ie. item[]=2&item[]=3&item[]=10
At the moment the "updatesql.php" file is simply setup so if the page is
called it connects to the database and updates a record. I dont make use
of the 'serial' data. This is how I know its not working. If I do :
data: serial.hash or data: serial, = nothing gets updated.
data: "name=John&location=Boston" = the table gets updated via updatesql.php

Chris,
The hash idea that the other site was talking about is what I was telling you in my previous post. I do this all the time:
function myFunction(email){
   var args = {};
   <a href="http://args.name">args.name</a> = $('#nameid').val();
   args.location = $('#locationid').val();
   args.email = email;
   args.someStringLiteral = "I am a string!";
   $.ajax({
      url:"updatesql.php",
      type:"post",
      data: args,
      error:function(){
         alert('Failed');
      },
<div id="1gxp" class="ArwC7c ckChnd">
      success:function(){
         alert('Success');
      }</div>   });
}
Note that in JavaScript what a hash (or what I would call a structure) is also an associative array, and it's an object, and both can be accessed using either dot or array notation. So if you had an object (hash/structure/associative array) called 'session' you could access the 'loggedin' property by saying session.loggedin or session['loggedin']. You could set up that hash/associative array/struct/object as I've mentioned above:
var session = {};
session.loggedin = true;
or
var session = {"loggedin":true};
Check this excellent page (<a href="http://www.quirksmode.org/js/associative.html">http://www.quirksmode.org/js/associative.html</a>) for much more detailed information. :o)
jQuery will take an object like this and translate it into the "name=John&location=Boston" for you. I find passing an object of arguments easier and more preferable (personally) than passing "name=John&location=Boston".

Hi Scott (and others),
Thanks for all the posts and help ! It actually did make some sense in
the end :).
The success message was based on AJAX success function, so that was
part of the confusion. It was giving me a success message but not
actually doing anything. Changing 'serial.hash' to be 'serial' also
helped - still not 100% clear what the hash is for. And the other
problem was in the PHP. I assumed that 'serial' was being posted with
the #id as the key, however it doesnt. It simply gets posted without a
key. Instead of doing $myarray = $_POST['my_sorted_id_block']; , it
needs to be $myarray = $_POST; , and then I cycle through the array
with a foreach().
I've now incorporated this into Zend Framework and works a treat.
Ta for all the help,
Chris. :)
