Mother category identified as class in the body tag

Support
#1

Hi

Is there a way to insert a class in the body tag related to the mother category in the product archive pages?

I’d like to stylish all products from the same mother category to have a different color…

Is it possible to do this?

I found this

But I couldn’t figure out in witch .php file I should insert this code…

Would you help, please?

Hi @priscilaps,

Thanks for reaching out.

That one needs to modify the actual header.php and <body> tag which isn’t recommended. You can then add this code to your child theme’s functions.php (appending to the end if there is any other codes).

add_filter('body_class', 'mother_category');

function mother_category($classes) {

if ( is_category() ) {

$this_category = get_category($cat);
if ($this_category->category_parent == 0) {
$this_category->category_parent = $cat;
} else {
$parent_category = get_category($this_category->category_parent);
$ParentCatId = $parent_category->cat_ID;
$ParentCatName = $parent_category->slug;
}
$childcategories = array();
$catx = $ParentCatId;
$cats = get_categories('parent='.$catx);
foreach($cats as $cat) {
$childcategories[] = $cat->term_id; } ;
if( is_category( $childcategories ) ) {
$class = 'child-category-of-'.$ParentCatName;
}
        $classes[] = $class;
}

        return $classes;

}

I use the code from the URL you have provided and made it work functions.php. This should serve as a guide on how it should be implemented as functions.php’s code and the proper use of body_class as a filter. We can’t cover any further modification of the code, especially it’s not from us :slight_smile:

Thanks!

Got it but not with that code above…

Got it by adding this one below in the function.php in the child theme

function woo_custom_taxonomy_in_body_class( $classes ){
    $custom_terms = get_the_terms(0, 'product_cat');
    if ($custom_terms) {
      foreach ($custom_terms as $custom_term) {

        // Check if the parent category exists:
        if( $custom_term->parent > 0 ) {
            // Get the parent product category:
            $parent = get_term( $custom_term->parent, 'product_cat' );
            // Append the parent class:
            if ( ! is_wp_error( $parent ) )
                $classes[] = 'product_parent_cat_' . $parent->slug;   
        }

        $classes[] = 'product_cat_' . $custom_term->slug;
      }
    }
    return $classes;
}

add_filter( 'body_class', 'woo_custom_taxonomy_in_body_class' );

Great news!
Thanks for sharing the code. This is very useful to other users too.
