custom http variables - 1.10

mihomes

Trying to understand how this is used - http://datatables.net/examples/server_side/custom_vars.html and the example isn't doing much for me. Is d.myKey available in scripts/server_processing.php then for that example or...?

Here is what I am looking to do. Majority of my data tables include a timestamp column. I want to include a date range filter on my page (there would be a start and end value) and pass onto my server-side processing so I can filter the data. Is that the type of thing this is intended for? Normally I would just use jquery to pass those variables onto my script then do what I need on that end, but I came across this and am a little confused how and what it is used for.

Yes - in that case you will be able to use $_GET['myKey'] to get the parameter.

Bang on! You might use something like:

$(document).ready(function() {
    $('#example').dataTable( {
        "processing": true,
        "serverSide": true,
        "ajax": {
            "url": "scripts/server_processing.php",
            "type": "POST",
            "data": function ( d ) {
                d.range_start = ...;
                d.range_end = ...;
            }
        }
    } );
} );

filling in the ... with how you get your values of course! Then you will have $_POST['range_start'] and $_POST['range_end'] at the server-side (I've used POST in this example, while the linked example uses GET).

Does that make sense?
