Add a filter to change teh ordering of the exported appointments

[Valentina R]

By default, they are ordered by appointment ID and it would be more useful if it would be the DateTime instead. Having a filter so that anyone could decide what they want would be the best.

Introducing 'woocommerce_appointment_export_data_args' with 4.9.10

[Valentina R]

Not working for ordering. At least not with these snippets:

add_filter('woocommerce_appointment_export_data_args', function($args){
  $args['orderby'] = array('Start timestamp' => 'DESC');
  return $args;
},1,99);

‌

add_filter('woocommerce_appointment_export_data_args', function($args){
  $args['orderby'] = array('start' => 'DESC');
  return $args;
},1,99);

‌

After 4.9.11, the following code snippet can be used for this:

add_filter( 'woocommerce_appointment_export_data_args', 'modify_appointment_export_data_args', 10, 2 );
function modify_appointment_export_data_args( $args, $exporter ) {
    $args['order_by'] = 'start_date';
    $args['order']    = 'DESC';

    return $args;
}
