Hi,
Yes! It is possible via a custom code snippet:
add_filter("asp_query_args", "asp_query_args_apply_date", 10, 2);
function asp_query_args_apply_date($args, $search_id) {
$args['post_meta_filter'][] = array(
'key' => '_EventStartDate',
'value' => date('Y-m-d'),
'operator' => '>=',
'allow_missing' => false
);
return $args;
}
Try adding this code via the Code Snippets plugin or to the functions.php file in your theme/child theme directory – make sure to have a full server back-up first for safety. For more details you can check the safe coding guidelines.
If you are using the snippets plugin, make sure the code can run everywhere.
