Can't Change WooCommerce Coupon Label In Cart Totals - wordpress

Question

This has proven to be a challenge I can't figure out. I handled the renaming of "Coupon" to "Promo" pretty much everywhere else. However, the renaming of the WC LABEL that calls the name of the coupon and the LABEL is a lot harder.
Here's a screenshot of what I'm talking about exactly:
I've pretty much renamed all the uses of "coupon" to "promo" site-wide. This one is making my hair fall out. Has anyone ever successfully changed this? What am I missing?
Rename "Coupon" to "Promo" code below
// rename the coupon field on the cart page
function woocommerce_rename_coupon_field_on_cart( $translated_text, $text, $text_domain ) {
// bail if not modifying frontend woocommerce text
if ( is_admin() || 'woocommerce' !== $text_domain ) {
return $translated_text;
}
if ( 'Coupon code:' === $text ) {
$translated_text = 'Promo Code:';
}
return $translated_text;
}
add_filter( 'gettext', 'woocommerce_rename_coupon_field_on_cart', 10, 3 );
// rename the "Have a Coupon?" message on the checkout page
function woocommerce_rename_coupon_message_on_checkout() {
return 'Have a Customer Code?' . ' <a href="#" class="showcoupon">' . __(
'Click here to enter your code', 'woocommerce' ) . '</a>';
}
add_filter( 'woocommerce_checkout_coupon_message',
'woocommerce_rename_coupon_message_on_checkout' );
// rename the coupon field on the checkout page
function woocommerce_rename_coupon_field_on_checkout( $translated_text, $text, $text_domain ) {
// bail if not modifying frontend woocommerce text
if ( is_admin() || 'woocommerce' !== $text_domain ) {
return $translated_text;
}
if ( 'Coupon code' === $text ) {
$translated_text = 'Promo Code';
} elseif ( 'Apply coupon' === $text ) {
$translated_text = 'Apply Code';
}
return $translated_text;
}
add_filter( 'gettext', 'woocommerce_rename_coupon_field_on_checkout', 10, 3 );
WC Coupon Notices/Message code below
function woocommerce_coupon_message( $translated_text, $text, $domain ) {
switch ( $translated_text ) {
case 'Coupon' :
$translated_text = __( 'Promo', 'woocommerce' );
break;
case 'promo' :
$translated_text = __( 'promo', 'woocommerce' );
break;
case 'Please enter a coupon code.' :
$translated_text = __( 'Please enter a Promo code.', 'woocommerce' );
break;
case 'Coupon code already applied!' :
$translated_text = __( 'Promo code already applied!', 'woocommerce' );
break;
case 'Coupon has been removed.' :
$translated_text = __( 'Promo has been removed', 'woocommerce' );
break;
case 'Coupon code applied successfully.' :
$translated_text = __( 'Promo code applied successfully.', 'woocommerce' );
break;
}
return $translated_text;
}
add_filter( 'gettext', 'woocommerce_coupon_message', 20, 3 );

Answer 1

// Hide 'Coupon: CODE' in cart totals and instead return generic 'Promo Code Applied'
add_filter( 'woocommerce_cart_totals_coupon_label', 'woocommerce_change_coupon_label' );
function woocommerce_change_coupon_label() {
echo 'Promo Code Applied';
}

Answer 2

add_filter( 'woocommerce_cart_totals_coupon_label', 'woocommerce_change_coupon_label' );
function woocommerce_change_coupon_label($sprintf, $coupon) {
return 'Promo ' . $coupon->code;
}

Answer 3

I found a solutions for all needs.
Works with WooCommerce v7.
function custom_cart_totals_coupon_label($sprintf, $coupon)
{
$coupon_code = $coupon->get_code();
$sprintf = '<span class="discount_label">'.__('Coupon', 'veganwebagency').':</span> <span class="discount_code">'.$coupon_code.'</span>';
return $sprintf;
}
add_filter('woocommerce_cart_totals_coupon_label', 'custom_cart_totals_coupon_label', 10, 2);
