Hey,

The code I used is a combination of your code and gmorleys code:

// custom Artist taxonomy for events
add_action( 'init', 'register_my_taxonomies', 0 );

function register_my_taxonomies() {
$labels = array(
    'name'                          => 'artists',
    'singular_name'                 => 'artist',
    'search_items'                  => 'Search Artists',
    'popular_items'                 => 'Popular Artists',
    'all_items'                     => 'All Artists',
    'parent_item'                   => 'Parent Artist',
    'edit_item'                     => 'Edit Artist',
    'update_item'                   => 'Update Artist',
    'add_new_item'                  => 'Add New Artist',
    'new_item_name'                 => 'New Artist',
    'separate_items_with_commas'    => 'Separate Artists with commas',
    'add_or_remove_items'           => 'Add or remove Artists',
    'choose_from_most_used'         => 'Choose from most used Artists'
    );

$args = array(
    'label'                         => 'Artists',
    'labels'                        => $labels,
    'public'                        => true,
    'hierarchical'                  => true,
    'show_ui'                       => true,
    'show_in_nav_menus'             => true,
    'args'                          => array( 'orderby' => 'term_order' ),
    'rewrite'                       => array( 'slug' => 'events/artists', 'with_front' => false ),
    'query_var'                     => true
);

register_taxonomy( 'artists', EM_POST_TYPE_EVENT, $args );
}

// custom taxonomy search and display
add_action('em_template_events_search_form_header','artists_search_form');
function artists_search_form(){
	$artists = (is_array(get_option('artists'))) ? get_option('artists'):array();
	?>
	<!-- START artists Search -->
	<select name="artist" id="artist_search">
		<option value="" selected="selected">Artists</option>
		<?php
		$taxonomies = array('artists');
		$args = array('orderby'=>'count','hide_empty'=>true);
		echo get_terms_dropdown($taxonomies, $args);
		?>
	</select>
	<!-- END artists Search -->
	<?php
}

function my_em_artists_event_load($EM_Event){
	global $wpdb;
	$EM_Event->artists = $wpdb->get_col("SELECT term_taxonomy_id FROM $wpdb->term_relationships WHERE object_id='{$EM_Event->post_id}'", 0	);
}
add_action('em_event','my_em_artists_event_load',1,1);

// And make the search attributes for the shortcode
add_filter('em_events_get_default_search','my_em_artists_get_default_search',1,2);
function my_em_artists_get_default_search($searches, $array){
	if( !empty($array['artist']) ){
		$searches['artist'] = $array['artist'];
	}
	return $searches;
}

add_filter('em_events_get','my_em_artists_events_get',1,2);
function my_em_artists_events_get($events, $args){
	if( !empty($args['artist'])  ){
		foreach($events as $event_key => $EM_Event){
			if( !in_array($args['artist'],$EM_Event->artists) ){
				unset($events[$event_key]);
			}
		}
	}
	return $events;
}

function get_terms_dropdown($taxonomies, $args){
	$myterms = get_terms($taxonomies, $args);

	foreach($myterms as $term){
		$root_url = get_bloginfo('url');
		$term_taxonomy=$term->taxonomy;

Hi,

What I want is that users can specify an extra taxonomy when submitting events (choosing from a list of trainers) on the front end page. So every event has one trainer attached to it.

On the event list page users should be able to search by trainer. So I need an extra drop down list here.

I’ve tried the code on this page by gmorley https://www.ads-software.com/support/topic/plugin-events-manager-searching-by-custom-taxonomy. I pasted the code in functions.php, but I don’t get an extra box on my search page. After that I tried your modification, but still without success.

anyone can help with this?

Sorry for the bump

I’m still not getting this to work, even with abovementioned modification. Should this still be working?

P.S. the tutorial has not been updated yet
