Sending data to server issue

Sending data to server issue

Hi,

I have a script which lets me take data from an XML page, and displays it on a form.

To do this I use:

$(function(){

$('#results').hide();

$("td[id^='weekcommencing_']").click(function() {
var week = $(this).text();
var url = "xml-data.php";
$.get(url, { week: week, store_number: 32492 }, fillinform);
});


});

function fillinform(week) {
 
 
   xmlDoc = $.parseXML( week );
     xml = $( xmlDoc );
 
           $('#daily_sales').val(xml.find('daily_sales').text() );
           $('#projected_sales').val(xml.find('projected_sales').text() );
           $('#daily_hours').val(xml.find('daily_hours').text() );
           $('#projected_hours').val(xml.find('projected_hours').text() );
           $('#holiday_hours').val(xml.find('holiday_hours').text() );
           $('#salary').val(xml.find('salaried').text() );
  $('#storeID').html(xml.find('store_number').text() );
           $('#date').html(xml.find('date').text() );
          $('#results').fadeIn(400);
     
 }
However, I need to now take the values I have and send them back to the XML file, which then updates the record on the database.

How would I go about doing this?
Thanks
