php - Apply different tax based on user role and product category (Woocommerce) -

i need apply different tax if user have specific role, in certains product's categories.

example: if customer role "vip" buy item of category "bravo" or "charlie" tax applied @ 4% instead 22%

this code in part wrote me part taken on google, don't understand wrong.

please can me?

function wc_diff_rate_for_user( $tax_class, $product ) {   global $woocommerce;      $lundi_in_cart = false;      foreach ( $woocommerce->cart->get_cart() $cart_item_key => $values ) {         $_product = $values['data'];         $terms = get_the_terms( $_product->id, 'product_cat' );              foreach ($terms $term) {                 $_categoryid = $term->term_id;             }                 if (( $_categoryid === 81 ) || ( $_categoryid === 82 ) )) {                      if ( is_user_logged_in() && current_user_can( 'vip' ) ) {                         $tax_class = 'reduced rate';                     }                 }        }    return $tax_class; } 

taxes calculated per lines of items in cart.. don't have loop cart items. instead, check if current item has category looking for.

try this...

add_filter( 'woocommerce_product_tax_class', 'wc_diff_rate_for_user', 1, 2 ); function wc_diff_rate_for_user( $tax_class, $product ) {      // not logged in users not vip, let's move on...     if (!is_user_logged_in()) {return $tax_class;}      // user not vip, let's move on...     if (!current_user_can( 'vip' ) ) {return $tax_class;}      // it's reduced rate, let's move on..     if ($tax_class == 'reduced rate') {return $tax_class;}      // let's product category product...     $terms = get_the_terms( $product->id, 'product_cat' );     foreach ( $terms $term ) { // checking each category          // if it's 1 of category we'er looking         if(in_array($term->term_id, array(81,82))) {             $tax_class = 'reduced rate';             // found it... no need check other $term             break;         }     }      return $tax_class; }
