Dynamic categories filtering

[ictcustomer28Participant]

Hello Support,
i have multiple search bar for each categorie with subcategories .
Could you tell me how to dynamically include new subcategories filters in each search bar when a user create new one?

Thanks
Best regards

Hi,

If you choose the “Use all from …” option, they will be included automatically on the filter: https://i.imgur.com/WYMU8mM.png

Hi Ernest,
thanks for your reply but this don’t resolve my question.
I have this situation :
Taxonomy Categories -> Parent Categories Test -> Child Category TestA , TestB
Taxonomy Categories -> Parent Categories Test2 -> Child Category TestC , TestD

In the filtering settings I’ve a checkbox for categories Test and all Child Category ( I don’t show categorie Test2 ) .

If I add a new Child Categories in Test , I cannot add them dynamically but I must go in settings page and adding the new Child category in the filtering .

I have multiple search instance with different categories and I would like to populate filtering checkbox automatically with newly create Child Categories.

I hope I explained better my need, sorry for bad English language but is not my primary language .
Thanks

In this case the only possible solution is to use a custom code – as there is no other way to force including all child terms.

I have constructed a small code snippet. All you need to edit is the $my_custom_fitlers array variable. I have included some explanation on how to use it.
For this to work, you must remove the existing filter, as the code will ad itt programmatically.

add_action('asp_pre_parse_filters', 'asp_add_my_own_filters', 10, 2);
function asp_add_my_own_filters($search_id, $options) {
	// This is the array of rules
	$my_custom_filters = array(
		array(
			'search_id' => 1,			// For which search ID should this filter exist
			'taxonomy' => 'category',	// Taxonomy name
			'parent_id' => 25,			// Parent term (category) ID for which include the child terms
			'label' => 'Label',			// The filter label
			'type' => 'checkboxes',		// The filter type
			'selected' => true			// Should the items be selected or not
		),
		array(
			'search_id' => 2,
			'taxonomy' => 'category',
			'parent_id' => 26,
			'label' => 'Label',
			'type' => 'checkboxes',
			'selected' => true
		)
	);

	// --- DO NOT CHANGE ANYTHING BELOW ----
	foreach( $my_custom_filters as $f ) {
		if ( $f['search_id'] == $search_id ) {
			// Creating a new filter
			$filter = wd_asp()->front_filters->create(
				'taxonomy',
				$f['label'],
				$f['type'],
				array(
					'taxonomy' => $f['taxonomy']
				)
			);

			$terms = array( get_term_by('id', $f['parent_id'], $f['taxonomy']) );
			$children = get_term_children($f['parent_id'], $f['taxonomy']);
			$terms = array_merge($terms, get_terms(array(
				'hide_empty' => false,
				'taxonomy' => $f['taxonomy'],
				'include' => $children
			)));
            $termsHierarchical = array();
            wd_sort_terms_hierarchicaly($terms, $termsHierarchical);
            wd_flatten_hierarchical_terms($termsHierarchical, $terms);
			foreach( $terms as $term ) {
				// Add each taxonomy terms one by one
				$filter->add(array(
					'id' => $term->term_id,
					'label' => $term->name,
					'level' => $term->level,
					'taxonomy' => $f['taxonomy'],
					'default' => false,
					'parent' => $f['parent_id'],
					'selected' => $f['selected']
				));
			}
			$filter->selectByOptions($options);
			wd_asp()->front_filters->add($filter);
		}
	}
}

Try adding this code 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.
