jQuery Grid Plugin - jqGrid

Hi,

I am trying to get the daveRow functionality working.

I have the editurl set to saveData.php and I'm assuming that when I call saveRow that should POST data to the php script.

At the momement, saveData.php only contains code to write a file to the server, I wanted to see if it was being called via jgrid, but it does not seem to be.

Here is the javascript...can anyone help..?

<script type="text/javascript">
var lastsel;
$(function(){
  $("#list").jqGrid({
    url:'example.php',
    datatype: 'xml',
    mtype: 'GET',
    colNames:['Inv No','Date', 'Amount','Tax','Total','Notes'],
    colModel :[
      {name:'id', index:'id', width:55},
      {name:'invdate', index:'invdate', width:90,editable:true},
      {name:'amount', index:'amount', width:80, align:'right',editable:true},
      {name:'tax', index:'tax', width:80, align:'right',editable:true},
      {name:'total', index:'total', width:80, align:'right',editable:true},
      {name:'note', index:'note', width:150, sortable:false,editable:true}
    ],
    pager: '#pager',
    rowNum:10,
    rowList:[10,20,30],
    sortname: 'amount',
    sortorder: 'desc',
    viewrecords: true,
    caption: '',
    editurl: "saveData.php",
    onSelectRow: function(id){
       if(id && id!==lastsel){
            jQuery('#list').jqGrid('restoreRow',lastsel);
            jQuery('#list').jqGrid('saveRow',id);
            jQuery('#list').jqGrid('editRow',id,true);
            lastsel=id;
        }
    }
  });
});
</script>

thank you
