I use this code to show the size attributes below each object on the shop archive tab, but it's showing the error.. How do I change the code to correct this error?
add_action('woocommerce_after_shop_loop_item_title', 'add_attribute', 5);
function add_attribute() {
$desired_att = 'Size';
global $product;
$product_variable = new WC_Product_Variable($product->id);
$product_variations = $product_variable->get_available_variations();
$numItems = count($product_variations);
echo '<span class="price">';
if ($numItems == 1) {
foreach ($product_variations as $variation) {
echo $variation[attributes]['attribute_pa_size'];
}
} else if ($numItems > 1) {
$i = 0;
foreach ($product_variations as $variation) {
if (++$i === $numItems) {
echo $variation[attributes]['attribute_pa_size'];
} else {
echo $variation[attributes]['attribute_pa_size'] . ", ";
}
}
}
echo '</span>';
}
