Output Hierarchical List of Upcoming Event Categories

[Ulf]

Hi there,

I’m hoping someone can help me out with this. Basically what I am trying to do is create a hierarchical list of all upcoming event categories (which will be used as a menu).

I am already able to output only upcoming event categories with the following code:

		<?php 
		// Get all of the upcoming events	
		$events = tribe_get_events( array(
		    'eventDisplay' => upcoming,
		    'posts_per_page' => -1,
		)); 
	
		// Loop through the upcoming events with tribe events category taxonomy
		foreach ( $events as $event ) {	
			//Put each upcoming category in an array
			$cats[] = get_terms( array(
				'taxonomy' => tribe_events_cat) 
			);
		} 
	
		//Grab unique categories and put those in an array
		$cat_results = array_unique($cats);
$count = 0;

		// Loop through the unique array of categories
		foreach($cat_results as $cat_result){
			// Loop through the terms
			foreach($cat_result as $the_result){
				// Output the name for each unique category
				echo $the_result->name . '<br/>';
			}
			
		} 	
		?>

However this returns a list that does not show any type of category hierarchy
e.g. This is what I get:
Adults
Boys
Camps
Christmas
Girls
High School
Kelowna, British Columbia
Mens
Pond Hockey
Quebec City, Quebec
Tournaments
Womens

However I would like to output a hierarchical list like so:
Camps
—Adults
—Christmas
Tournaments
—Boys
——Quebec City, Quebec
—Girls
—High School
——Kelowna, British Columbia
—Mens
—Pond Hockey
—Womens

I believe that I am already headed in the right direction, if you have a look at the following code, I am able to break the list up by the parent categories. However the sub-categories listed below the parent are not displaying ONLY subcategories with upcoming events – they are displaying ALL subcategories.

		<?php  

		$parentCategories = get_terms(array(
			'taxonomy' => tribe_events_cat,
			'parent' => 0, 
			'orderby' => 'slug', 
			'hide_empty' => false 
		) );
		foreach($parentCategories as $pcat){
			echo '<strong>' . $pcat->name . '</strong><br/>';

			// GET ALL EVENTS THAT ARE UNDER THE PARENT CATEGORY
			$leEvents = tribe_get_events( array(
			    'eventDisplay' => upcoming,
			    'posts_per_page' => -1,
			    'tax_query' => array(
					    array(
						    'taxonomy' => 'tribe_events_cat',
						    'field' => 'slug',
						    'terms' => $pcat->slug
					    ))			    
			)); 
			
			foreach($leEvents as $leEvent){
			
				$leagueCategories = get_terms( array( 
					'taxonomy' => tribe_events_cat,				
					'parent' => $pcat->term_id, 
					'orderby' => 'slug', 
					'hide_empty' => false
				) );	
			}
					
			foreach($leagueCategories as $lecat){
				echo $lecat->name . '<br/>';

				// GET ALL EVENTS THAT ARE UNDER THE PARENT CATEGORY
				$locEvents = tribe_get_events( array(
				    'eventDisplay' => upcoming,
				    'posts_per_page' => -1,
				    'tax_query' => array(
						    array(
							    'taxonomy' => 'tribe_events_cat',
							    'field' => 'slug',
							    'terms' => $lecat->slug
						    ))			    
				)); 

				foreach($locEvents as $locEvent){
					$locationCategories = get_terms( array( 
						'taxonomy' => tribe_events_cat,				
						'parent' => $lecat->term_id, 
						'orderby' => 'slug', 
						'hide_empty' => false 
					) );
				}	
				
				foreach($locationCategories as $locat){
					echo $locat->name . '<br/>';
					
				}
			}
		}

I am aware that you are limited in the amount of customization you can help out with, that being said if you have any input at all as to why this may not be working as expected – that would be very much appreciated.


Thank you.

Hi. Thanks for all the details.

Why do you have 'hide_empty' => false?

Your // Loop through the upcoming events with tribe events category taxonomy does a foreach() but doesn’t use $event.

You should also probably either wrap tribe_events_cat in quotes or do this: 'taxonomy' => Tribe__Events__Main::TAXONOMY,

As you know, we can’t do this customization for you… but maybe looking at the source code of the wp_list_categories() function might help you with your logic?

Please let me know if any of this helped.

Hi Cliff,

Thank you very much for the reply, that was incredibly helpful. It was definitely the ‘hide_empty’ => false that was giving me the unexpected output. I believe I had originally copy and pasted that from what I found on a support thread and never questioned it.

Thanks again!

[Cliff]

Awesome! I’m very glad I was able to help you get across the finish line.

Have a great rest of your week.
