Parent product category page in Woocommerce - php

Question

Is it possible in Woocommerce, if the product category page shows its subcategories, to do any actions? I need to add a class to the body tag on such pages. Is it real? Example:
function my_custom_body_class_woo_cat($classes) {
if ( is_product_category() && is_subcategory_show() ) {
$classes[] = 'my-class';
return $classes;
}
}
add_filter('body_class','my_custom_body_class_woo_cat');`
I tried to look for solutions, but I didn't find one

Answer 1

I checked woocommerce conditional tags and is_subcategory_show() is not a valid woocommerce function.
So in order for this to work we need to do our own checks before assigning the extra class or classes to the body.
Here is a code snippet that does what you asked( if i understood your question correctly ):
add_filter('body_class', function ($classList) {
// Not a product category, return the classList intact
if (!is_product_category()) {
return $classList;
}
$desiredDisplayType = 'subcategories';
$term = get_queried_object();
// Not a parent category, return classList intact
if ($term->parent !== 0) {
return $classList;
}
// Get the woocommerce category archive display option (the one you set up in the customizer)
$categoryArchiveDisplayOption = get_option('woocommerce_category_archive_display');
// Get the display type for the current category
$currentCategoryDisplayOption = get_term_meta($term->term_id, 'display_type', true);
// The current category displatype isn't the desired one, return classList intact
if ($currentCategoryDisplayOption !== $desiredDisplayType) {
return $classList;
}
// Neither of the option are the desired one, return classList intact
if (
$currentCategoryDisplayOption !== $desiredDisplayType
&& $categoryArchiveDisplayOption !== $desiredDisplayType
) {
return $classList;
}
// All checks passed, add my class to body
return array_merge($classList, ['my-class']);
});
Woocommerce has a general option in the customizer where you set up if you want category archives to display subcategories.
Then when you edit a specific category you can assign a display type specific to that category, so this should take precedence over the general option.
