如果购物车数量不能被特定数字整除，请禁用 WooCommerce Checkout

Question

我有一些代码可以检查 WooCommerce 中的产品数量是否可以被 6 整除 - 但是即使显示了通知，客户仍然可以使用不正确的数量结账。

如果不满足条件，如何禁用 WooCommerce 'Place Order' 结帐？

// check that cart items quantities totals are in multiples of 6
add_action( 'woocommerce_check_cart_items', 'woocommerce_check_cart_quantities' );
function woocommerce_check_cart_quantities() {
  global $woocommerce;
  $multiples = 6;
    $total_products = 0;
    foreach ( $woocommerce->cart->get_cart() as $cart_item_key => $values ) {
        $total_products += $values['quantity'];
    }
    if ( ( $total_products % $multiples ) > 0 )
        wc_add_notice( sprintf( __('You need to buy in quantities of %s products', 'woocommerce'), $multiples ) );
}

钩子 woocommerce_check_cart_items 需要一个“错误”通知来禁用结帐 （事实并非如此）。我还简化了代码：

// Check cart items conditionally displaying an error notice and avoiding checkout
add_action( 'woocommerce_check_cart_items', 'check_cart_items_conditionally' );
function check_cart_items_conditionally() {
    $multiple_of = 6; // <= Here set the "multiple of" number

    if ( ( WC()->cart->get_cart_contents_count() % $multiple_of ) != 0 ) {
        wc_add_notice( sprintf( __('You need to buy in quantities of %s products', 'woocommerce'), $multiple_of ), 'error' );
    }
}

可选： 为确保无法访问结帐，您可以添加以下内容，如果购物车商品总数不是 N 的倍数，则将结帐重定向到购物车页面：

// To be sure: redirect checkout to cart page if cart items count is not a multiples of N
add_action( 'template_redirect', 'redirect_checkout_to_cart_conditionally' );
function redirect_checkout_to_cart_conditionally() {
    $multiple_of = 6; // <= Here set the "multiple of" number

    if ( is_checkout() && ( WC()->cart->get_cart_contents_count() % $multiple_of ) != 0 ) {
        wp_redirect( wc_get_cart_url() );
        exit();
    }
}

代码进入活动子主题（或活动主题）的 functions.php 文件。已测试并有效。
