需要在產品組合上禁用優惠券（我通過付費插件創建）

我有一個醫學網站，客戶來這里購買產品。

有 2 個頁面我制作了組合，如果有任何客戶，但來自這些組合/頁面的產品，我想禁用優惠券。請告訴我..

Woocommerce 內置了優惠券設定來執行此操作。從優惠券限制欄位中排除這些產品。檢查此螢屏截圖：https ://snipboard.io/pug8Oo.jpg

你可以使用這樣的東西。

add_filter( ‘woocommerce_coupon_is_valid_for_product’, ‘sw_wc_apfs_disable_on_susbcription’, 10, 4 );

function sw_wc_apfs_disable_on_susbcription( $is_valid, $product, $instance, $values ) {

if ( ! empty( $values[ ‘wcsatt_data’][ ‘active_subscription_scheme’ ] ) ) {
$is_valid = false;
}

return $is_valid;
}

如果您有多種產品，那么有多種選擇。

1. 在產品頁面上創建禁用優惠券欄位。將以下代碼放入您的 chid 主題的 functions.php 檔案中。學分

// Create and display the custom field in product general setting tab
add_action( 'woocommerce_product_options_general_product_data', 'add_custom_field_general_product_fields' );
function add_custom_field_general_product_fields(){
    global $post;

    echo '<div >';

    // Custom Product Checkbox Field
    woocommerce_wp_checkbox( array(
        'id'        => '_disabled_for_coupons',
        'label'     => __('Disabled for coupons', 'woocommerce'),
        'description' => __('Disable this products from coupon discounts', 'woocommerce'),
        'desc_tip'  => 'true',
    ) );

    echo '</div>';;
}

// Save the custom field and update all excluded product Ids in option WP settings
add_action( 'woocommerce_process_product_meta', 'save_custom_field_general_product_fields', 10, 1 );
function save_custom_field_general_product_fields( $post_id ){

    $current_disabled = isset( $_POST['_disabled_for_coupons'] ) ? 'yes' : 'no';

    $disabled_products = get_option( '_products_disabled_for_coupons' );
    if( empty($disabled_products) ) {
        if( $current_disabled == 'yes' )
            $disabled_products = array( $post_id );
    } else {
        if( $current_disabled == 'yes' ) {
            $disabled_products[] = $post_id;
            $disabled_products = array_unique( $disabled_products );
        } else {
            if ( ( $key = array_search( $post_id, $disabled_products ) ) !== false )
                unset( $disabled_products[$key] );
        }
    }

    update_post_meta( $post_id, '_disabled_for_coupons', $current_disabled );
    update_option( '_products_disabled_for_coupons', $disabled_products );
}

// Make coupons invalid at product level
add_filter('woocommerce_coupon_is_valid_for_product', 'set_coupon_validity_for_excluded_products', 12, 4);
function set_coupon_validity_for_excluded_products($valid, $product, $coupon, $values ){
    if( ! count(get_option( '_products_disabled_for_coupons' )) > 0 ) return $valid;

    $disabled_products = get_option( '_products_disabled_for_coupons' );
    if( in_array( $product->get_id(), $disabled_products ) )
        $valid = false;

    return $valid;
}

// Set the product discount amount to zero
add_filter( 'woocommerce_coupon_get_discount_amount', 'zero_discount_for_excluded_products', 12, 5 );
function zero_discount_for_excluded_products($discount, $discounting_amount, $cart_item, $single, $coupon ){
    if( ! count(get_option( '_products_disabled_for_coupons' )) > 0 ) return $discount;

    $disabled_products = get_option( '_products_disabled_for_coupons' );
    if( in_array( $cart_item['product_id'], $disabled_products ) )
        $discount = 0;

    return $discount;
}

2. 如果要禁用所有優惠券，請添加此代碼。學分

function bulk_edit_coupon_restrictions(){
    // Only for admin users (not accessible) for other users)
    if( ! current_user_can( 'manage_options' ) ) return;

    global $wpdb;

    // Set HERE the product IDs without discount
    $product_ids = array( 37, 67 );

    $product_ids = implode( ',', $product_ids );  // String conversion

    // SQL query: Bulk update coupons "excluded product" restrictions
    $wpdb->query( "
        UPDATE {$wpdb->prefix}postmeta as pm
        SET pm.meta_value = '$product_ids'
        WHERE pm.meta_key = 'exclude_product_ids'
        AND post_id IN (
            SELECT p.ID
            FROM {$wpdb->prefix}posts as p
            WHERE p.post_type = 'shop_coupon'
            AND p.post_status = 'publish'
        )
    " );
}
// Run this function once (and comment it or remove it)
bulk_edit_coupon_restrictions();

3. 如果您使用的是 Yith 禮品卡插件，請使用此代碼。學分

  if( defined('YITH_YWGC_PREMIUM') ){
 if( !function_exists('yith_wcgc_deny_coupon_on_gift_card') ){
  add_action('woocommerce_applied_coupon','yith_wcgc_deny_coupon_on_gift_card');

  function yith_wcgc_deny_coupon_on_gift_card( $coupon_code ){
      global $woocommerce;
      $the_coupon = new WC_Coupon( $coupon_code );
      $excluded_items = $the_coupon->get_excluded_product_ids();
      $items = $woocommerce->cart->get_cart();
      foreach ( $items as $item ):
    if( has_term('gift-card','product_type',$item['product_id']) == true ):
        $excluded_items[] = $item['product_id'];
    endif;
      endforeach;
      $the_coupon->set_excluded_product_ids($excluded_items);
      $the_coupon->save();
      wc_add_notice( 'Coupon cannot applied to gift card product', 'error' );

  }
 }
}

4. 此選項可以隱藏特定產品類別的優惠券欄位。為此使用下面的代碼。學分

add_filter( 'woocommerce_coupons_enabled', 'conditionally_hide_cart_coupon_field' );
function conditionally_hide_cart_coupon_field( $enabled ) {
    // Set your special category name, slug or ID here:
    $special_cat = array('clothing');
    $bool = false;

    foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
        $wc_product = $cart_item['data'];
        // Woocommerce compatibility
        $product_id = method_exists( $wc_product, 'get_id' ) ? $wc_product->get_id() : $wc_product->id;

        $main_product_id = $cart_item['variation_id'] > 0 ? $cart_item['product_id'] : $product_id;
        if ( has_term( $special_cat, 'product_cat', $main_product_id ) )
            $bool = true;
    }

    if ( $bool && is_cart() ) {
        $enabled = false;
    }
    return $enabled;
}

我希望這將幫助您實作所需的輸出。
