Its really neccesary post all PHP code?

At top of my file i have:

$page = $_GET['page']; // get the requested page
$limit = $_GET['rows']; // get how many rows we want to have into the grid
echo “limit: “.$limit;
$sidx = $_GET['sidx']; // get index row – i.e. user click to sort
$sord = $_GET['sord']; // get the direction

rest of code here…

i printed $limit var and i get a empty value.

EDIT:

I tested all grid vars ($page, $limit, $sidx, $sord) and all post empty values at PHP file.

My actual PHP file is:

$page = $_GET['page'];
echo “page: “.$page;
$limit = $_GET['rows'];
echo “limit: “.$limit;
$sidx = $_GET['sidx'];
echo “sidx: “.$sidx;
$sord = $_GET['sord'];
echo “sord: “.$sord;

Regards

Fixed! omg small error are the more difficult. I have mtype: POST at grid config and my PHP file use $_GET method haha

Thx all, regards.
