在 WooCommerce 购物车中设置全局最低金额（餐饮类别 + 子类别除外）

Question

我正在尝试将最低订单金额设置为 51.50 欧元，但“餐饮 + 子类别”类别除外，该类别可以单独添加，无论购物车中的金额如何。

到目前为止，我发现了两个代码，它们各自工作得很好。现在，由于错误消息，我尝试将这两个函数合并为一个函数。 目前，即使通过第二个功能在购物车中找到餐饮产品，由于第一个功能，始终会出现全局错误消息。

/**
 * Set a minimum order amount for checkout - works fine
*/

add_action( 'woocommerce_checkout_process', 'wc_minimum_order_amount' );
add_action( 'woocommerce_before_cart' , 'wc_minimum_order_amount' );

function wc_minimum_order_amount() {
    // Set this variable to specify a minimum order value - 51.50
    $minimum = 51.50;

    if ( WC()->cart->total < $minimum ) {

        if( is_cart() ) {

            wc_print_notice(
                sprintf( '| Ihr Bestellwert muss mindestens %s (inkl.Versandkosten) betragen um eine Bestellung abzugeben. —  Ihr aktueller Warenwert liegt bei %s.' ,
                    wc_price( $minimum ),
                    wc_price( WC()->cart->total )
                ), 'error'
            );

        } else {

            wc_add_notice(
                sprintf( 'Ihr Bestellwert muss mindestens %s (inkl.Versandkosten) betragen um eine Bestellung abzugeben. —  Ihr aktueller Warenwert liegt bei %s.' ,
                    wc_price( $minimum ),
                    wc_price( WC()->cart->total )
                ), 'error'
            );

        }
    }
}

这是要检查的代码，购物车中是否有餐饮产品，该产品运行良好，但目前是单独的：

add_action( 'woocommerce_check_cart_items', 'minimum_order_amount_for_subcategories' );
function minimum_order_amount_for_subcategories() {
    $term_slug   = 'catering'; // <==  Define the targeted main product category slug
    $threshold   = 51.50; // <==  Define the minimum amount threshold

    $taxonomy    = 'product_cat'; // WooCommerce product category taxonomy
    $subtotal    = 0; // Itintializing
    $found       = false; // Itintializing
    
    // Get the children terms Ids from the main product category term slug
    $main_term   = get_term_by( 'slug', $term_slug, $taxonomy );
    $childen_ids = get_term_children( $main_term->term_id, $taxonomy );
    $terms_ids   = array_merge( array($main_term->term_id), $childen_ids);
    
    foreach( WC()->cart->get_cart() as $cart_item ) {
        // Check for specific product category children term ids
        if ( has_term( $terms_ids, $taxonomy, $cart_item['product_id'] ) ) {
            $found = true; // At least subcategory is found
            
            // Get non discounted subtotal including taxes from subcategories
            $subtotal += $cart_item['line_subtotal'] + $cart_item['line_subtotal_tax']; 
            
            
        }
    }

    if ( $found && $subtotal < $threshold ) {
        
        wc_add_notice( sprintf(
            __( "Bestellwert muss mindestens %s der Kategorie %s betragen", "woocommerce" ),
            wc_price($threshold),
            '"<strong>' . ucfirst($term_slug) . '</strong>"' 
        ), 'error' );
    }
}

谢谢亲切的问候， 迷宫

我感受到你的痛苦:)但是一旦你看到完成的代码，下次你将能够处理任何“条件逻辑”功能。

这应该有效：

add_action( 'woocommerce_checkout_process', 'wc_minimum_order_amount' );
add_action( 'woocommerce_before_cart' , 'wc_minimum_order_amount' );

function wc_minimum_order_amount() {

    // Set this variable to specify a minimum order value - 51.50
    $threshold = 51.50;
    $term_slug = 'catering';
    $taxonomy = 'product_cat'; // WooCommerce product category taxonomy
    $subtotal = 0; // Initializing
    $found = false; // Initializing

    // Get the children terms Ids from the main product category term slug
    $main_term   = get_term_by( 'slug', $term_slug, $taxonomy );
    $children_ids = get_term_children( $main_term->term_id, $taxonomy );
    $terms_ids = array_merge( array($main_term->term_id), $children_ids);

    foreach( WC()->cart->get_cart() as $cart_item ) {
        // Check for specific product category children term ids
        if ( has_term( $terms_ids, $taxonomy, $cart_item['product_id'] ) ) {
            $found = true; // At least subcategory is found
    
            // Get non discounted subtotal including taxes from subcategories
            $subtotal += $cart_item['line_subtotal'] + $cart_item['line_subtotal_tax']; 

        }
    }

    if ( $found && $subtotal < $threshold ) {

        if ( is_cart() ) {

            wc_print_notice(
                sprintf( '| Ihr Bestellwert muss mindestens %s (inkl.Versandkosten) betragen um eine Bestellung abzugeben. —  Ihr aktueller Warenwert liegt bei %s.' ,
                    wc_price( $minimum ),
                    wc_price( WC()->cart->total )
                ), 'error'
            );

        } else {

            wc_add_notice(
                sprintf( 'Ihr Bestellwert muss mindestens %s (inkl.Versandkosten) betragen um eine Bestellung abzugeben. —  Ihr aktueller Warenwert liegt bei %s.' ,
                    wc_price( $minimum ),
                    wc_price( WC()->cart->total )
                ), 'error'
            );

        }
    }
}
