            console.log(data);
        },
        dom: 'lBfrtip',
        buttons: [

    });

Answer 1

On php you will get a param filter_start_date which will be sent on every datatables ajax request . Just use it to filter your results.

And in javascript you can do something like this to reload the table

$('#filter_start_date').change(function() {
    oTable.ajax.reload();
});

EDIT:

Here's exactly how I use it:

$('#table').DataTable({
   //configs
   ajax: {
      url: baseUrl('/ajax/load-docs'),
      type: 'post',
      data: function(d) {
          d.initial_date = $('#initial_date').val();
      }
   }
});

and in php

$date = $this->getParam('initial_date'); //getParam from Zend_Framework Controller

in your case you can use $_POST['filter_start_date']
