$g->set_options($grid);

$e["on_update"] = array("update_client", null, true);
$g->set_events($e);
function update_client($data)
{
$str = "UPDATE invheader set total=(select sum(qty*unit) from invlines where id = {$data["id"]} ) WHERE id = {$data["id"]};";
//$str = "UPDATE invheader set total=1 WHERE id = {$data["id"]};";

// echo $str;

$mysql_query($str);
// echo $str;
// continue normal grid update … by grid lib
}

Perhaps, there is a typo …

$mysql_query($str); should be …

mysql_query($str);
(without $ sign)

You can put echo statements inside on_update callback and see output in firebug ajax response.
Review this tutorial for '[debugging with firebug](https://phpgrid.desk.com/customer/portal/articles/926266)'.
