I am working on to get the categories of each product which is ordered using below code.
function get_order_detail($order_id){
$order = wc_get_order( $order_id );
foreach ($order->get_items() as $item_key => $item ){
$product = $item->get_product();
$categorieID = $product->category_ids[0];
$categorie_title = get_the_category_by_ID($categorieID);
}
}
But the products which were having variants like size, colour in their variations, they are returning the value of $categorieID as NULL.
Use the following instead to get the product category term names for each order item:
function get_order_detail( $order_id ) {
$order = wc_get_order( $order_id );
foreach ( $order->get_items() as $item_id => $item ) {
// Get the product category(ies) term(s) name(s) - (array)
$term_names = wp_get_post_terms( $item->get_product_id(), 'product_cat', array('fields' => 'names') );
// Set them as a coma separated string
$categories_string = implode(',', $term_names);
}
}
or you can get the product category Ids using the following:
function get_order_detail( $order_id ) {
$order = wc_get_order( $order_id );
foreach ( $order->get_items() as $item_id => $item ) {
// Get the product category(ies) term(s) Id(s) - (array)
$term_ids = wp_get_post_terms( $item->get_product_id(), 'product_cat', array('fields' => 'ids') );
}
}
This will work for all product types even variations of a variable product.
