i want to create three nested subgrids. each of the related tables as a unique id has a column called id.
So I gave an alias to the id column say detail_id
I set
$opt_pp[“subGrid”] = true;
$opt_pp[“subgridurl”] = “grid_price_subgrid_init.php”;
$opt_pp[“subgridparams”] = “detail_id”;

And the dependent subgrid (the one with grid_prices_subgrid_init.php) can’t read detail_id

Although:
if (!empty($_POST[“detail_id”]))
$_SESSION[“detail_id”] = $_POST[“detail_id”];
$detail_id = $_SESSION[“detail_id”];

I get sql error:
here’s an excerpt
WHERE project_id = GROUP BY employee

and the sql code looks like:
WHERE project_id = $detail_id GROUP BY employee

🙁

What to do???
