[Function] Current Term Has Children

A user asks:

I’m working on an archive template for WooCommerce products.

I’m trying to hide a section if there are no child categories but I cannot figure out how to set the conditions to do this.

Anyone else know what term or dynamic data to use to get this to work?

We can define a custom function that uses get_term_children() to return true or false, then use it with Bricks’ Dynamic data condition to render a Section (or any element) only if the current term has children.

Add this in child theme’s functions.php or a code snippets plugin:

// Function to check if the current term of the given taxonomy has children
function bl_current_term_has_children( $taxonomy = 'category' ) {
	$term_children = get_term_children( get_queried_object_id(), $taxonomy );

	return count( $term_children ) > 0;
}

get_queried_object_id() gets the ID of the current term when viewing a term archive page. Example URL:

https://bricks.local/product-category/clothing/accessories/

We have set category as the default argument for the function.

To check for a different taxonomy, product_cat in this case:

{echo:bl_current_term_has_children(product_cat)}

Now the function is ready to be used in a term archive template like a template that applies to all WooCommerce product categories.

Apply a Dynamic data condition with the above dynamic data tag whilst checking it against being equal to 1.

Remember that 1 is true and 0 is false.
