jQuery Grid Plugin - jqGrid

Hi all and sorry for my english..

I have been investigating my code and I can't understand why don't work it...

I can get the rows from my MySQL database but when I edit a row, this is edited only local. The POST doesn't include the new information and when I press reload button, old value return again.

The example is here: /blog/jqgrid/jqgrid.html Row editing using events  -->

HTML

 ...

<table id="rowed3"></table>

<div id="prowed3"></div>

<br />

<script src="rowedex3.js" type="text/javascript"> </script>

Java Scrpt code

 ...

var lastsel;

jQuery("#rowed3").jqGrid({

url:'server.php?q=2',

datatype: "json",

colNames:['Inv No','Date', 'Client', 'Amount','Tax','Total','Notes'],

colModel:[

{name:'id',index:'id', width:55},

{name:'invdate',index:'invdate', width:90, editable:true},

{name:'name',index:'name', width:100,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}

],

rowNum:10,

rowList:[10,20,30],

pager: '#prowed3',

sortname: 'id',

viewrecords: true,

sortorder: "desc",

onSelectRow: function(id){

if(id && id!==lastsel){

jQuery('#rowed3').jqGrid('restoreRow',lastsel);

jQuery('#rowed3').jqGrid('editRow',id,true);

lastsel=id;

}

},

editurl: "server.php",

caption: "Using events example"

});

jQuery("#rowed3").jqGrid('navGrid',"#prowed3",{edit:false,add:false,del:false});

PHP with MySQL

...

$page = $_GET['page']; // get the requested page

$limit = $_GET['rows']; // get how many rows we want to have into the grid

$sidx = $_GET['sidx']; // get index row - i.e. user click to sort

$sord = $_GET['sord']; // get the direction

if(!$sidx) $sidx =1;

// connect to the database

$db = mysql_connect($dbhost, $dbuser, $dbpassword)

or die("Connection Error: " . mysql_error());

mysql_select_db($database) or die("Error conecting to db.");

$result = mysql_query("SELECT COUNT(*) AS count FROM invheader a, clients b WHERE a.client_id=b.client_id");

$row = mysql_fetch_array($result,MYSQL_ASSOC);

$count = $row['count'];

if( $count >0 ) {

$total_pages = ceil($count/$limit);

} else {

$total_pages = 0;

}

if ($page > $total_pages) $page=$total_pages;

$start = $limit*$page - $limit; // do not put $limit*($page - 1)

$SQL = "SELECT a.id, a.invdate, b.name, a.amount,a.tax,a.total,a.note FROM invheader a, clients b WHERE a.client_id=b.client_id ORDER BY $sidx $sord LIMIT $start , $limit";

$result = mysql_query( $SQL ) or die("Couldn t execute query.".mysql_error());

$responce->page = $page;

$responce->total = $total_pages;

$responce->records = $count;

$i=0;

while($row = mysql_fetch_array($result,MYSQL_ASSOC)) {

$responce->rows[$i]['id']=$row[id];

$responce->rows[$i]['cell']=array($row[id],$row[invdate],$row[name],$row[amount],$row[tax],$row[total],$row[note]);

$i++;

}

echo json_encode($responce);
