I have managed to create a basic grid, but i am now getting this error when trying to make the new data in editable cells save to the database – also the data is not being displayed in the grid anymore

Couldn t execute query.You have an error in your SQL syntax; check the manual that corresponds to your

MySQL server version for the right syntax to use near '-10 , 10' at line 1

My php -

<?php 
$dbhost = xxxxxx.com';  $dbuser = 'xxxxxxxx';  $dbpassword = 'xxxxxx';  $dbdatabase = xxxxx;
 
$page = $_REQUEST['page'];  // get the requested page
$limit = $_REQUEST['rows']; // get how many rows we want to have into the grid
$sidx = $_REQUEST['sidx']; // get index row - i.e. user click to sort
$sord = $_REQUEST['sord']; // get the direction
if(!$sidx) $sidx =1;
// connect to the database
$db = mysql_connect($dbhost, $dbuser, $dbpassword) or die("Connection Error: " . mysql_error());
mysql_select_db($dbdatabase) or die("Error conecting to db.");
$result = mysql_query("SELECT COUNT(*) AS count FROM invheader a, clients b WHERE a.client_id=b.client_id".$wh);
$row = mysql_fetch_array($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);
?>

Take a second look at your SQL query, the error says it all.
You are not allowed to have a LIMIT with a negative number, which is your case.
You start with LIMIT -10, 10, instead of LIMIT 0,10.

right thanks - I'm slowly getting there.

However I cant get the data to save to the database - I know its probably something really simple, but coding is not really my thing - just trying to help out a friend. Here is my latest html. I seem to be going round in cicrcles when i google...

many thanks
