Change WooCommerce product description tab button and title - php

Question

I want to change the WooCommerce product description tab button and title "Description" into "Tracklist" when the page has a body class of "parent-product_cat-vinyl".
Here is my code so far:
<?php
if ( is_singular() ) {
$classes = get_body_class();
if (in_array('parent-product_cat-vinyl',$classes)) {
add_filter( 'woocommerce_product_description_tab_title','ps_rename_description_product_tab_label');
function ps_rename_description_product_tab_label() {
return 'Tracklist';
}
}
}
But it doesn't seem to work.

You can use the following composite filter hooks (where $tab_key is in your case description):
woocommerce_product_{$tab_key}_tab_title
woocommerce_product_{$tab_key}_heading
It can be done in 2 ways:
Conditionally with a defined body class:
add_filter( 'woocommerce_product_description_tab_title', 'change_product_description_tab_text' );
add_filter( 'woocommerce_product_description_heading', 'change_product_description_tab_text' );
function change_product_description_tab_text( $title ) {
global $product;
if( in_array( 'parent-product_cat-vinyl', get_body_class() ) ) {
return __('Tracklist', 'woocommerce');
}
return $title;
}
Or conditionally for a product category (including parent product categories):
// Custom conditional function that handle parent product categories too
function has_product_categories( $categories, $product_id = 0 ) {
$parent_term_ids = $categories_ids = array(); // Initializing
$taxonomy = 'product_cat';
$product_id = $product_id == 0 ? get_the_id() : $product_id;
if( is_string( $categories ) ) {
$categories = (array) $categories; // Convert string to array
}
// Convert categories term names and slugs to categories term ids
foreach ( $categories as $category ){
$result = (array) term_exists( $category, $taxonomy );
if ( ! empty( $result ) ) {
$categories_ids[] = reset($result);
}
}
// Loop through the current product category terms to get only parent main category term
foreach( get_the_terms( $product_id, $taxonomy ) as $term ){
if( $term->parent > 0 ){
$parent_term_ids[] = $term->parent; // Set the parent product category
$parent_term_ids[] = $term->term_id; // (and the child)
} else {
$parent_term_ids[] = $term->term_id; // It is the Main category term and we set it.
}
}
return array_intersect( $categories_ids, array_unique($parent_term_ids) ) ? true : false;
}
add_filter( 'woocommerce_product_description_tab_title', 'change_product_description_tab_text' );
add_filter( 'woocommerce_product_description_heading', 'change_product_description_tab_text' );
function change_product_description_tab_text( $title ) {
global $product;
// Here set in the array the targeted product categories
$categories = array('Vinyl');
if ( has_product_categories( $categories, $product->get_id() ) ) {
return __('Tracklist', 'woocommerce');
}
return $title;
}
Code goes in functions.php file of your active child theme (or active theme) . Tested and works.
