Display coupon description and id on thankyou.php - wordpress

Question

Basicly, I would like to display the coupon used on Woocommerce thankyou.php. Here is the code I have added
$coupons = $order->get_items( 'coupon' );
foreach ( $coupons as $item_id => $item ) {
echo "<span class='coupon-name'><b>".$item['name']."</b></span>";
$post = get_post( $item_id );
echo "<p class='coupon-description'>".$post->post_excerpt."</p>";
}
However, only the coupon code is shown while the description does not.
Here is where I placed my code:
if ( ! defined( 'ABSPATH' ) ) {
exit;
}
if ( $order ) : ?>
<?php if ( $order->has_status( 'failed' ) ) : ?>
<p class="woocommerce-thankyou-order-failed"><?php _e( 'Unfortunately your order cannot be processed as the originating bank/merchant has declined your transaction. Please attempt your purchase again.', 'woocommerce' ); ?></p>
<p class="woocommerce-thankyou-order-failed-actions">
<?php _e( 'Pay', 'woocommerce' ) ?>
<?php if ( is_user_logged_in() ) : ?>
<?php _e( 'My Account', 'woocommerce' ); ?>
<?php endif; ?>
</p>
<?php else : ?>
<?php
$coupons = $order->get_items( 'coupon' );
foreach ( $coupons as $item_id => $item ) {
echo "<span class='coupon-name'><b>".$item['name']."</b></span>";
$post = get_post( $item_id );
echo "<p class='coupon-description'>".$post->post_excerpt."</p>";
}
?>
<p class="woocommerce-thankyou-order-received"><?php echo apply_filters( 'woocommerce_thankyou_order_received_text', __( 'Thank you. Your order has been received.', 'woocommerce' ), $order ); ?></p>
<ul class="woocommerce-thankyou-order-details order_details">
<li class="order">
<?php _e( 'Order Number:', 'woocommerce' ); ?>
<strong><?php echo $order->get_order_number(); ?></strong>
</li>
<li class="date">
<?php _e( 'Date:', 'woocommerce' ); ?>
<strong><?php echo date_i18n( get_option( 'date_format' ), strtotime( $order->order_date ) ); ?></strong>
</li>
<li class="total">
<?php _e( 'Total:', 'woocommerce' ); ?>
<strong><?php echo $order->get_formatted_order_total(); ?></strong>
</li>
<?php if ( $order->payment_method_title ) : ?>
<li class="method">
<?php _e( 'Payment Method:', 'woocommerce' ); ?>
<strong><?php echo $order->payment_method_title; ?></strong>
</li>
<?php endif; ?>
</ul>
<div class="clear"></div>
<?php endif; ?>
<?php do_action( 'woocommerce_thankyou_' . $order->payment_method, $order->id ); ?>
<?php do_action( 'woocommerce_thankyou', $order->id ); ?>
<p class="woocommerce-thankyou-order-received"><?php echo apply_filters( 'woocommerce_thankyou_order_received_text', __( 'Thank you. Your order has been received.', 'woocommerce' ), null ); ?></p>
Could anyone please help me with this?

Answer 1

add_filter('woocommerce_get_order_item_totals','change_discount',10,3);
function change_discount($total_rows, $order, $tax_display){
if ( $order->get_total_discount() > 0 ) {
$coupons = $order->get_used_coupons();
$total_rows['discount'] = array( 'label' => __( 'Coupon code: '.implode(",",$coupons), 'woocommerce' ), 'value' => '-' . $order->get_discount_to_display( $tax_display ), );
}
return $total_rows;
}

Answer 2

you can get like this
if( $order->get_used_coupons() ) {
$coupons_count = count( $order->get_used_coupons() );
echo '<h4>' . __('Coupons used') . ' (' . $coupons_count . ')</h4>';
echo '<p><strong>' . __('Coupons used') . ':</strong> ';
$i = 1;
$coupons_list = '';
foreach( $order->get_used_coupons() as $coupon) {
$coupons_list .= $coupon;
if( $i < $coupons_count )
$coupons_list .= ', ';
$i++;
}
echo '<p><strong>Coupons used (' . $coupons_count . ') :</strong> ' . $coupons_list . '</p>'; }

Please use this code, I hope it will work for you:
<?php
add_action('woocommerce_thankyou', 'apply_product_on_coupon');
function apply_product_on_coupon() {
global $woocommerce;
if ( ! empty( $woocommerce->cart->applied_coupons ) ) {
$my_coupon = $woocommerce->cart->get_coupons() ;
foreach($my_coupon as $coupon){
if ( $post = get_post( $coupon->id ) ) {
if ( !empty( $post->post_excerpt ) ) {
echo "<span class='coupon-name'><b>".$coupon->code."</b></span>";
echo "<p class='coupon-description'>".$post->post_excerpt."</p>";
}
}
}
}
}
?>
If this will not work then use coupon shortcode plugin and call shortcode on the thankyou page

<?php echo do_shortcode('[coupon_shortcode]'); ?>
