Display parent grouped product name in Woocommerce orders details - php

Question

For Woocommerce grouped products I am displaying parent product name in cart and checkout pages using the code bellow:
// Adding the grouped product ID custom hidden field data in Cart object
add_action( 'woocommerce_add_cart_item_data', 'save_custom_fields_data_to_cart', 10, 2 );
function save_custom_fields_data_to_cart( $cart_item_data, $product_id ) {
if( ! empty( $_REQUEST['add-to-cart'] ) && $product_id != $_REQUEST['add-to-cart'] ) {
$cart_item_data['custom_data']['grouped_product_id'] = $_REQUEST['add-to-cart'];
$data['grouped_product_id'] = $_REQUEST['add-to-cart'];
// below statement make sure every add to cart action as unique line item
$cart_item_data['custom_data']['unique_key'] = md5( microtime().rand() );
WC()->session->set( 'custom_data', $data );
}
return $cart_item_data;
}
// Add the parent grouped product name to cart items names
add_filter( 'woocommerce_cart_item_name', 'custom_product_title_name', 10, 3 );
function custom_product_title_name( $cart_item_name, $cart_item, $cart_item_key ){
// Only in cart and checkout pages
if ( is_cart() || is_checkout() )
{
// The product object from cart item
$product = $cart_item['data'];
$product_permalink = $product->is_visible() ? $product->get_permalink( $cart_item ) : '';
// The parent product name and data
if( ! empty( $cart_item['custom_data']['grouped_product_id'] ) ){
$group_prod_id = $cart_item['custom_data']['grouped_product_id'];
$group_prod = wc_get_product($group_prod_id);
if ( ! $group_prod->is_type( 'grouped' ) ) return $cart_item_name;
$parent_product_name = $group_prod->get_name();
$group_prod_permalink = $group_prod->is_visible() ? $group_prod->get_permalink() : '';
if ( ! $product_permalink )
return $parent_product_name . ' > ' . $product->get_name();
else
return sprintf( '%s > %s', esc_url( $group_prod_permalink ), $parent_product_name, esc_url( $product_permalink ), $product->get_name() );
}
else
return $cart_item_name;
}
else
return $cart_item_name;
}
Code comes from here: Add the parent product name to each cart item names in WooCommerce
Now I would like to display also this parent product name in orders details and in back-end too.
I will be grateful for any help on this.

I have revisited the original code answer a bit and I have enabled the display of those parent products linked names on orders and email notifications:
// Adding the grouped product ID custom hidden field data in Cart object
add_filter( 'woocommerce_add_cart_item_data', 'save_custom_fields_data_to_cart', 20, 2 );
function save_custom_fields_data_to_cart( $cart_item_data, $product_id ) {
if( ! empty($_REQUEST['add-to-cart']) && $product_id != $_REQUEST['add-to-cart']
&& is_numeric($_REQUEST['add-to-cart']) ){
$group_prod = wc_get_product($_REQUEST['add-to-cart']);
if ( ! $group_prod->is_type( 'grouped' ) )
return $cart_item_data; // Exit
$cart_item_data['grouped_product'] = array(
'id' => $_REQUEST['add-to-cart'],
'name' => $group_prod->get_name(),
'link' => $group_prod->get_permalink(),
'visible' => $group_prod->is_visible(),
);
// Below statement make sure every add to cart action as unique line item
$cart_item_data['grouped_product']['unique_key'] = md5( microtime().rand() );
}
return $cart_item_data;
}
// Add the parent grouped product name to cart items names
add_filter( 'woocommerce_cart_item_name', 'custom_product_title_name', 20, 3 );
function custom_product_title_name( $cart_item_name, $cart_item, $cart_item_key ){
// The product object from cart item
$product = $cart_item['data'];
$product_permalink = $product->is_visible() ? $product->get_permalink( $cart_item ) : '';
// The parent product name and data
if( isset( $cart_item['grouped_product'] ) ){
$group_product = $cart_item['grouped_product'];
$group_prod_link = $product->is_visible() && is_cart() ? $group_product['link'] : '';
if ( ! $group_prod_link )
return $group_product['name'] . ' > ' . $product->get_name();
else
return sprintf(
'%s > %s',
esc_url( $group_prod_link ),
$group_product['name'],
esc_url( $product_permalink ),
$product->get_name()
);
}
else
return $cart_item_name;
}
// Save grouped product data in order item meta
add_action( 'woocommerce_checkout_create_order_line_item', 'added_grouped_order_item_meta', 20, 4 );
function added_grouped_order_item_meta( $item, $cart_item_key, $values, $order ) {
if( isset($values['grouped_product']) ){
$item_id = $item->get_id();
$grouped_data = $values['grouped_product'];
unset($grouped_data['unique_key']);
$item->update_meta_data( '_grouped_product', $grouped_data );
}
}
// Display grouped product linked names in order items (+ email notifications)
add_filter( 'woocommerce_order_item_name', 'custom_order_item_name', 20, 3 );
function custom_order_item_name( $item_name, $item, $is_visible ) {
$product = $item->get_product();
$product_id = $item->get_product_id();
$product_permalink = $is_visible ? $product->get_permalink( $item ) : '';
$grouped_data = wc_get_order_item_meta( $item->get_id(), '_grouped_product', true );
if( empty($grouped_data) ){
$item_name = $product_permalink ? sprintf(
'%s',
esc_url( $product_permalink),
$item->get_name()
) : $item->get_name();
} else {
$item_name = $product_permalink ? sprintf(
'%s > %s',
$grouped_data['link'],
$grouped_data['name'],
esc_url( $product_permalink) ,
$item->get_name()
) : $grouped_data['name'] . ' > ' . $item->get_name();
}
return $item_name;
}
// Display on backend order edit pages
add_action( 'woocommerce_before_order_itemmeta', 'backend_order_item_name_grouped', 20, 3 );
function backend_order_item_name_grouped( $item_id, $item, $product ){
if( ! ( is_admin() && $item->is_type('line_item') ) ) return;
$grouped_data = wc_get_order_item_meta( $item_id, '_grouped_product', true );
if( empty($grouped_data) ) return;
$product_link = admin_url( 'post.php?post=' . $grouped_data['id'] . '&action=edit' );
$grouped_name_html = '' . esc_html( $grouped_data['name'] ) . '';
echo '<br><br><div class="wc-order-item-name">
<small><strong>'.__('Grouped parent').':</strong></small><br>
' . $grouped_name_html . '
</div>';
}
Code goes in function.php file of your active child theme (or theme);
Tested and works.
