Show/hide results based on a datetime metafield

Hi Samuele,

Yes – it is possible two ways – one is a bit of custom code snippet, or if you are not using the search filters, then that is also an option. Search filters are effective even if they are invisible.

Therefore you can create a date filter on that field like so: https://i.imgur.com/rGCSVpw.png
This will filter out results where the “start-date” is before today.

Sure Samuele! I would also prefer a custom code snippet if I were you, good choice 🙂

This is what you are looking for:

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'     => 'start-date',
		'value'   => strtotime("today", time()),
		'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.

Hi Samuele,

'allow_missing' => true should do the trick. It will allow results where the custom field does not exist and apply the filter where it does.
