This example shows the basic steps to make the grid editable. To do that we need 3 steps.
1. Mark which column in the grid is editable. This is done with a new property "editable:true"
By default all columns in the grid are not editable.
2. Specify the url where the server accept the posted data. This is done with a option "editurl".
3. Use the three new methods: editRow, saveRow, restoreRow.
- editRow(rowid, keys) - accept two parametres:- rowid - the unique id of the row and keys - which
when true - we can use Enter and Escape keys to save and cancel editing.
- saveRow( rowid, callback, url, extraparams)
rowid - unique id of the row, callback - custom function - when defined accept data returned from the server after posting,
url - when specified - overwrite the editurl parameter, extraparams - additinal params that can be passed to the server.
When data is posted the format is id=rowid&name=value..., where the name is the "name" from colModel.
- restoreRow( rowid) - restores the data to original values before the editing of the row. Note: Due to security reasons data is not saved to this server.

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]);
