Custom PLU field in woocommerce email [duplicate] - wordpress

Question

Is there any way I can add content from a custom product field to 'order completed' WooCommerce emails?
I have added this code to my functions.php in order to save my custom field to the product meta information.
//1.1 Display Activation Instructions field in admin
add_action('woocommerce_product_options_inventory_product_data', 'woocommerce_product_act_fields');
function woocommerce_product_act_fields(){
global $woocommerce, $post;
echo '<div class="product_custom_field">';
woocommerce_wp_text_input(
array(
'id' => '_act',
'label' => __('Activation Instructions', 'woocommerce'),
'desc_tip' => 'true',
'description' => 'Enter the Activation Instructions Link.'
)
);
echo '</div>';
}
//1.2 Save Activation Instructions field in product meta
add_action('woocommerce_process_product_meta', 'woocommerce_product_act_field_save');
function woocommerce_product_act_field_save($post_id){
$woocommerce_act_product_text_field = $_POST['_act'];
if (!empty($woocommerce_act_product_text_field))
update_post_meta($post_id, '_act', esc_attr($woocommerce_act_product_text_field));
}
I have also added this code to display a custom text on my 'order completed' woocomerce emails.
add_action( 'woocommerce_email_customer_details', 'bbloomer_add_content_specific_email', 20, 4 );
function bbloomer_add_content_specific_email( $order, $sent_to_admin, $plain_text, $email ) {
if ( $email->id == 'customer_completed_order' ) {
echo '<h2>Activation & Download Instructions</h2><p style="margin-bottom:35px;">Please refer to
our Activation Guides for detailed
activation and download instructions.</p>';
}
}
The above code works well and it displays the custom text for all 'order completed' emails.
But, I want to replace the URL part of the text with the custom product field data. The data is different for every product.
Thanks.

Use: get_post_meta to retrieves a post meta field for the given post ID.
//1.1 Display Activation Instructions field in admin
function woocommerce_product_act_fields() {
echo '<div class="product_custom_field">';
woocommerce_wp_text_input(
array(
'id' => '_act',
'label' => __('Activation Instructions', 'woocommerce'),
'desc_tip' => 'true',
'description' => 'Enter the Activation Instructions Link.'
)
);
echo '</div>';
}
add_action('woocommerce_product_options_inventory_product_data', 'woocommerce_product_act_fields', 10, 0 );
//1.2 Save Activation Instructions field in product meta
function woocommerce_product_act_field_save( $product ) {
if( isset($_POST['_act']) ) {
$product->update_meta_data( '_act', sanitize_text_field( $_POST['_act'] ) );
}
}
add_action( 'woocommerce_admin_process_product_object', 'woocommerce_product_act_field_save', 10, 1 );
//2 Add url to email
function woocommerce_product_act_email( $order, $sent_to_admin, $plain_text, $email ) {
if ( $email->id == 'customer_completed_order' ) {
$items = $order->get_items();
echo '<h2>Activation & Download Instructions</h2>';
foreach ( $items as $item ) {
// Get product ID
$product_id = $item->get_product_id();
// Get product name
$product_name = $item->get_name();
// Get post meta
$url = get_post_meta( $product_id, '_act', true);
if ( $url ) {
echo '<p style="margin-bottom:35px;">For ' . $product_name . ' follow these instructions</p>';
}
}
}
}
add_action( 'woocommerce_email_customer_details', 'woocommerce_product_act_email', 20, 4 );

add_action( 'woocommerce_email_customer_details', 'bbloomer_add_content_specific_email', 20, 4 );
function bbloomer_add_content_specific_email( $order, $sent_to_admin, $plain_text, $email ) {
if ( $email->id == 'customer_completed_order' ) {
$items = $order->get_items();
foreach ( $items as $item ) {
// Get product ID
$product_id = $item->get_product_id();
// Get post meta
$url = get_post_meta( $product_id, '_act', true );
if ( $url ) {
echo '<h2>'.$item->get_name().'Activation & Download Instructions</h2><p style="margin-bottom:35px;">Please refer to our Activation Guides for detailed activation and download instructions.</p>';
}
}
}
}
