Show attribute values on Woocommerce category archive pages - php

Question

In a Wordpress + Woocommerce website I have a menu with some custom links that recall specific shop pages URLs using advanced queries taxonomies.
These are example links I use for these custom menu entries:
https://example.com/product-category/cat1/?pa_attrib1=value1&pa_attrib2=value3
https://example.com/product-category/cat2/?pa_attrib1=value2&pa_attrib3=value4`
https://example.com/product-category/cat2/?pa_attrib1=value5&pa_attrib4=value5,value7,value8,value9
In this way I can configure "direct" entries to the various shop departments.
Now I need to show, in the shop and archive page, the name and the values of the attributes set in the url in a similar way:
Category Name - Attribute 1 name: value1 - Atttribute 2 Name: value2, ...
I suppose I need to use the hook woocommerce_archive_description in functions.php but I don't know how recall and show the values I need
add_action ( 'woocommerce_archive_description', 'show_term_description', 20 );
function show_term_description() {
echo term_description( $term_id, $taxonomy ); // print Category Name
// ...
// ...
}
thanks

This can be done with the following commented code inserted in your hooked function:
add_action ( 'woocommerce_archive_description', 'show_term_description', 20 );
function show_term_description() {
// Only for product category archive pages
if( ! is_product_category()) return;
global $wp;
// Get the requested Url category/subcategories
$request = $wp->request;
// Set them in an array
$request = explode( '/', $request );
// Remove 'product-category' from the array
if( 'product-category' == $request[0] )
unset($request[0]);
// Starting html formatting
$html = '<p><strong>';
// The main category and sub-categories names
foreach( $request as $category ){
// Get the category name
$category_term = get_term_by( 'slug', $category, 'product_cat' );
// Set category and subcategories in an array
$categories_name[] = $category_term->name;
}
// Formatting the category/subcategories in an html string
$html .= implode( '</strong> - <strong>', $categories_name );
// The product attributes names and related values
if( ! empty($_GET) ){
$html .= '</strong> - <strong>'; // Formatting html
$count = 0; // Initializing the counter
$attr_count = count($_GET); // get the length of the array
// Loop through the attribute/values from the $_GET
foreach($_GET as $taxonomy => $values ){
$count++;
$terms_names = array(); // Initializing
// If the taxonomy doesn't exist,
if( ! taxonomy_exists( $taxonomy ) ){
continue; // We go to next attribute
}
// Set the attribute terms in an array
$term_slugs = explode( ',', $values );
// Loop through the attribute term
foreach( $term_slugs as $term_slug ){
// Get the WP_Term object
$term = get_term_by( 'slug', $term_slug, $taxonomy );
if( ! term_exists( $term->term_id, $taxonomy ) )
continue; // We go to next term
// Set The term name in an array
$terms_names[] = $term->name;
}
// If there is no corresponding terms for the taxonomy
if( sizeof($terms_names) == 0 ){
continue; // We go to next attribute
}
// Add the attribute label name to the output
if( $count > 1 ) $html .= ' - ';
$html .= wc_attribute_label( $taxonomy );
// Formatting the term names in a string and add them to the output
$html .= ':</strong> ' . implode( ', ', $terms_names) . '<strong>';
}
}
// Outputing The html
echo $html.'</p>';
echo $attr_count .' | '.$count;
}
Code goes in function.php file of your active child theme (or theme) or also in any plugin file.
Tested and works…
