I created a grid panel with a store.
Data are from a PHP script.
It is possible to modify data in the grid (rowEditing) and to update the store.

When the user click on a button in the grid toolbar, data are sent to a PHP script on the server. I can see it in Firebug.

The question is : how can I get the data transmitted in PHP ? I can't see them in the POST or the GET variables... I think it's very simple, but I can't do it.
