Hide the Apply Gift Card field for certain roles

For example, if you have a “wholesale” role and do not want to show the Apply Gift Card field you can add this code.

1. Download the free Code Snippets plugin: https://wordpress.org/plugins/code-snippets/
2. Create a Snippet with the following code (or you can add this to your Child Theme’s functions.php if you prefer):

add_action( 'woocommerce_init', 'pwgc_woocommerce_init', 11 );
function pwgc_woocommerce_init() {
    global $pw_gift_cards_redeeming;

    // List of roles who should not see the "Apply Gift Card" form.
    $hidden_for_these_roles = array(
        'wholesale',
        'another_role',
    );

    $hide = false;
    if ( is_user_logged_in() ) {
        $user = wp_get_current_user();
        $user_roles = (array) $user->roles;

        foreach ( $user_roles as $role ) {
            if ( in_array( $role, $hidden_for_these_roles ) ) {
                $hide = true;
                break;
            }
        }
    }

    if ( $hide ) {
        remove_action( 'woocommerce_proceed_to_checkout', array( $pw_gift_cards_redeeming, 'woocommerce_proceed_to_checkout' ) );
        remove_action( 'woocommerce_after_cart_contents', array( $pw_gift_cards_redeeming, 'woocommerce_after_cart_contents' ) );
        remove_action( 'woocommerce_before_checkout_form', array( $pw_gift_cards_redeeming, 'woocommerce_before_checkout_form' ), 40 );
        remove_action( 'woocommerce_review_order_before_submit', array( $pw_gift_cards_redeeming, 'woocommerce_review_order_before_submit' ) );
    }
