如果未达到特定类别的最低数量，则阻止WooCommerce结账 [英] Prevent WooCommerce checkout if minimum quantity for a specific category is not reached

问题描述

我有一些购物车逻辑，如果购物车中有冷藏类别中的1件商品，它会检查至少3件商品。-这是经过测试的，并且工作正常。

但是，如果我从其他类别(环境)向购物车添加另一个项目，并且购物车中现在同时有冷藏和环境项目，则不再应用该规则。

如果购物车中也有环境物品，我如何确保应用了3冰镇最低限度规则？

// Set minimum quantity per product before checking out
add_action( 'woocommerce_check_cart_items', 'protein_set_min_total' );
    function protein_set_min_total() {
        // Only run in the Cart or Checkout pages
        if( is_cart() || is_checkout() ) {

            global $woocommerce, $product;
            $i=0;
          
            // Set minimum product cart total
            //And initialise product catergory counters
            $minimum_protein = 3;
            $total_protein = 0;
            $cat_in_cart = false;

            foreach ( $woocommerce->cart->cart_contents as $product ) :
                if ( has_term( 'chilled', 'product_cat', $product['product_id'] ) ) {
                   $total_protein += $product['quantity'];
                }
            endforeach;
          
            if (has_term( 'chilled', 'product_cat', $product['product_id'] ) && $total_protein < $minimum_protein) {
                wc_add_notice( sprintf( '<strong>A Minimum of %s products are required from The CHILLED category before checking out.</strong>'
                . '<br />Current number of Chilled items in the cart: %s.',
                    $minimum_protein,
                    $total_protein ),
                'error' );
            }
        //}
    }
}

推荐答案

以下代码将计算属于chilled类别的所有项目。仅当此值等于或大于3时，才能继续订购过程。

因此您得到：

function action_woocommerce_check_cart_items() {
    // Only run on the cart or checkout pages
    if ( is_cart() || is_checkout() ) {     
        // Minimum
        $minimum = 3;
        
        // Category
        $category = 'chilled';
        
        // Initialize
        $total = 0;
        
        // Loop through cart items        
        foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {        
            // Product id
            $product_id = $cart_item['product_id'];

            // Has certain category
            if ( has_term( $category, 'product_cat', $product_id ) ) {              
                // Add to total
                $total += $cart_item['quantity'];
            }
        }
        
        // When total is greater than 0 but less than the minimum
        if ( $total > 0 && $total < $minimum ) {
            // Notice
            wc_add_notice( sprintf( __( 'A minimum of %s products are required from the %s category before checking out.', 'woocommerce' ), $minimum, $category ), 'error' );
            
            // Optional: remove proceed to checkout button
            remove_action( 'woocommerce_proceed_to_checkout', 'woocommerce_button_proceed_to_checkout', 20 );
        }
    }
}   
add_action( 'woocommerce_check_cart_items' , 'action_woocommerce_check_cart_items', 10, 0 );
