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)}
Whitelist the bl_current_term_has_children function.
Ex.:
<?php
add_filter( 'bricks/code/echo_function_names', function() {
return [
'bl_current_term_has_children'
];
} );You should also add other functions (native or custom) being used in your Bricks instance besides bl_current_term_has_children. This can be checked at Bricks → Settings → Custom code by clicking the Code review button.
More info on whitelisting can be found here.
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.

Thanks for sharing!
Does it still work for you in 2024?
I just tried it and the section I added the condition to is hidden on both categories with and without children 🙁

Make sure you whitelist the custom function.
I updated the post with info on how to do that.

Thanks for sharing! I was looking for this particular solution.

My product category has children but the moment I add the condition to bricks it hides my section with sub-categories anyway 🙁

How would one do this inside of a query loop, instead of on an archive page? Like if I had a query loop on a standard page of my website. How do I check if the parent terms inside the query has children using bricks conditions?

Hi David,
From the tutorial, use the same function but change..
get_queried_object_id() to \Bricks\Query::get_loop_object_id()
Then use the condition on elements inside the first loop which you want to conditionally display (not on the loop itself)
More info on that \Bricks\Query::get_loop_object_id() found here..
