I created a custom taxonomy, which works perfectly. Now I just need to figure out how to make it searchable. I followed the instructions on the Events Manager page http://wp-events-plugin.com/tutorials/creating-a-events-manager-add-on-a-complete-walkthrough/ by following step 6 and 7. It creates a dropdown but none of the artist names show up
Here is the code I used
// 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, $args );
}
// custom taxonomy search and display
add_filter('em_events_get_default_search','artists_get_default_search',1,2);
function artists_get_default_search($searches, $array){
if( !empty($array['artist']) && is_numeric($array['artist']) ){
$searches['artist'] = $array['artist'];
}
return $searches;
}
add_filter('em_events_get','artists_events_get',1,2);
function artists_events_get($events, $args){
if( !empty($args['artist']) && is_numeric($args['artist']) ){
foreach($events as $event_key => $EM_Event){
if( !in_array($args['artist'],$EM_Event->artists) ){
unset($events[$event_key]);
}
}
}
return $events;
}
add_action('em_template_events_search_form_ddm', 'artists_search_form');
function artists_search_form(){
$artists = (is_array(get_option('Artists'))) ? get_option('Artists'):array();
?>
<!-- START Styles Search -->
<select name="artist">
<option value=''>Artists</option>
<?php foreach($artists as $artist_id=>$artist_name): ?>
<option value="<?php echo $artist_id; ?>" <?php echo ($_POST['artist'] == $artist_id) ? 'selected="selected"':''; ?>><?php echo $artist_name; ?></option>
<?php endforeach; ?>
</select>
<!-- END Styles Search -->
<?php
}
function artists_accepted_searches($searches){
$searches[] = 'artist';
return $searches;
}
add_filter('em_accepted_searches','artists_accepted_searches',1,1);
