Hi,
In my subgrid_detail i fetch the _POST(SN) then i want to use it to make a select…like this:
// you can provide custom SQL query to display data
$serial = mysql_real_escape_string($_POST['SN']);
$g->select_command = "SELECT * FROM thermo WHERE SN = '$serial'";
The issue is that mysql return no results…where is the error?
(if i do echo $serial i see that the SN is correct but it seems that into the query is empty)
Thanks

The POST cannot be used in query directly.
You need a session variable persistance.
e.g.
if (!empty($_POST["SN"]))
{
$_SESSION["SN"] = $_POST["SN"];
}
$serial = $_SESSION["SN"];
and use `$serial` in your SQL.
