Slider Range with two custom fields?

Hi,

Well, I’m afraid this is not possible, maybe via a custom code. I have constructed a possible solution, but I could not test this, so be very careful. Make sure to create a range slider for the minTimezone custom field for this to work. The code will automatically identify and then separate it to two individual min/max query arguments with the correct fields right before the search.

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.

add_filter("asp_query_args", "asp_query_args_change", 10, 2);
function asp_query_args_change($args, $search_id) {
	global $wpdb;
	foreach ( $args['post_meta_filter'] as $k => $filter) {
		if ( $filter['key'] == 'minTimezone' ) {
			$min = $filter['value'][0];
			$max = $filter['value'][1];
			unset($args['post_meta_filter'][$k]);
			
			// add the min
			$args['post_meta_filter'][] = array(
				'key'     => 'minTimezone',
				'value'   => $min,
				'operator'=> '>=',
				'allow_missing' => false 
			);
			
			// add the max
			$args['post_meta_filter'][] = array(
				'key'     => 'maxTimezone',
				'value'   => $max,
				'operator'=> '<=',
				'allow_missing' => false 
			);
			
			break;
		}
	}
	return $args;
}
