WooCommerce：设置特定产品的最低购买金额

PHP代码段：在WooCommerce单一产品和购物车页面上，根据购买的最低金额设置特定产品的“最小添加到购物车”数量
在下面的示例中，我为商品ID = 123设置了最低购买金额$50。此功能将需要在单个产品页面和购物车页面上起作用。如果产品ID = 123，价格为$ 9，则$min的金额为：ceil（50/9）= 6

// ------------
// 1. Single Product Page
 
add_filter( 'woocommerce_quantity_input_min', 'bloomer_woocommerce_quantity_min_50_eur', 9999, 2 );
   
function bloomer_woocommerce_quantity_min_50_eur( $min, $product ) {  
 
   if ( is_product() ) {
      if ( 123 === $product->get_id() ) {
         $min = ceil( 50 / $product->get_price() );
      }
 
   }
    
   return $min;
 
}
 
// ------------
// 2. Cart Page
 
add_filter( 'woocommerce_cart_item_quantity', 'bloomer_woocommerce_quantity_min_50_eur_cart', 9999, 3 );
   
function bloomer_woocommerce_quantity_min_50_eur_cart( $product_quantity, $cart_item_key, $cart_item ) {  
    
   $_product = apply_filters( 'woocommerce_cart_item_product', $cart_item['data'], $cart_item, $cart_item_key );
    
   $min = 0;
 
   if ( 123 === $_product->get_id() ) {
      $min = ceil( 50 / $_product->get_price() );
   }
    
   $product_quantity = woocommerce_quantity_input( array(
      'input_name'   => "cart[{$cart_item_key}][qty]",
      'input_value'  => $cart_item['quantity'],
      'max_value'    => $_product->get_max_purchase_quantity(),
      'min_value'    => $min,
      'product_name' => $_product->get_name(),
   ), $_product, false );
    
   return $product_quantity;
 
}
