This is part of my .js file. This defines a schema and a model to feed the table, and below is the relevant part that gets the info from the .php file:

...
},
        batch: true,
        pageSize: 8,
        schema:
        {
            data: "data",
            total: function(response)
            {
              return $(response.data).length;
            },
            model:
...


In the .php file i only have this:

header("Content-type: application/json");

$statement = $pdo->query("SELECT ... etc etc..
$statement->execute();
$result = $statement->fetchAll(PDO::FETCH_ASSOC);
echo "{\"data\":" .json_encode($result). "}";

If i use this code, the table returns results, but my problem is i need to feed the table and also send the var session...the reason why i need this is because it´s a clients table, and when you create a new table, it has to register the user that has login and thus inserting a new client.
