最低购物车金额，产品类别除外

Question

我正在尝试设置购物车的最低金额以允许客户结帐。但是我想对一个产品类别做个例外，即使它不符合最低要求的 200，我也会允许客户继续。

我的代码可以正常工作几乎除了：

通知中显示的购物车计算金额（错误）。
此特殊类别的独占条件 501（除此特殊类别外，当其他类别的产品也在购物车中时，无法按预期工作） .

这是我的代码：

add_action( 'woocommerce_check_cart_items', 'oxynergy_set_min_total' );
    function oxynergy_set_min_total() {
    // Only run in the Cart or Checkout pages
    if( is_cart() || is_checkout() ) {

        global $woocommerce, $product;
        $i=0;
        // Minimum order checking
        $minimumCheck = false;
        // Set minimum cart total
        $minimum_cart_total = 200;
        //loop through all cart products
        foreach ( $woocommerce->cart->cart_contents as $product ) {
            // Total we are going to be using for the Math
            // This is before taxes and shipping charges
            $total = WC()->cart->total;

            // See if any product is from the STOCK category or not
            if ( has_term( '481', 'product_cat', $product['product_id'] ) || has_term( '482', 'product_cat', $product['product_id'] )  || has_term( '495', 'product_cat', $product['product_id'] ) ) {
                $minimumCheck = true;
                //Get price of that product
                $regular_price = get_post_meta($product['product_id'], '_regular_price', true); //change to _sale_price if it is in sale
                //echo $regular_price."<br>";
                $total = $regular_price * $product['quantity']; 
                //echo $total."<br>";
                $subtotal_cat += $total; //get total of 
                //echo $subtotal_cat;
                //$category_price += ( $product['line_subtotal'] + $product['line_subtotal_tax'] );

            }
            if (has_term( '501', 'product_cat', $product['product_id']) ) {
                //Get price of that product
                $regular_price = get_post_meta($product['product_id'], '_regular_price', true); //change to _sale_price if it is in sale
                //echo $regular_price."<br>";
                $total = $regular_price * $product['quantity']; 
                //echo $total."<br>";
                $subtotal_cat += $total; //get total of 
                //echo $subtotal_cat;
                //$category_price += ( $product['line_subtotal'] + $product['line_subtotal_tax'] );
            }

        }


            if ( $minimumCheck && $subtotal_cat <= $minimum_cart_total) {

                // Compare values and add an error is Cart's total
                // happens to be less than the minimum required before checking out.
                // Will display a message along the lines of
                // A Minimum of 200 USD is required before checking out. (Cont. below)
                // Current cart total: 6 USD 
                wc_add_notice( sprintf( '<strong>A Minimum of %s %s excl. TAX is required category before checking out.</strong>'
                        .'<br />Current cart\'s total: %s %s excl. TAX',
                        $minimum_cart_total,
                        get_option( 'woocommerce_currency'),
                        $subtotal_cat,
                        get_option( 'woocommerce_currency') ),
                    'error' );
            }


    }

}

我做错了什么？
我怎样才能使此代码工作以专门为该特殊产品类别设置例外？

谢谢。

如果我明白了，您需要为产品类别禁用定义的 "Minimal required total cart amount" 且排他性 ，但如果有来自其他产品类别的其他购物车项目则不需要用它。

所以你只需要在下面的代码中设置这个产品类别ID，你不需要任何购物车的计算。

我也没有使用 has_term() 函数来避免 parent/child 产品类别的一种错误。相反，我使用 wp_get_post_terms() 和一个 foreach 循环…

我一直在更改您的代码：

add_action( 'woocommerce_check_cart_items', 'oxynergy_set_min_total' );
function oxynergy_set_min_total() {
    // Only run in the Cart or Checkout pages
    if( is_cart() || is_checkout() ) {

        // Set HERE your minimum cart total
        $minimum_cart_total = 200;
        // Set HERE your special product category ID
        $special_category = 501; 

        //Iterating through each cart items
        foreach ( WC()->cart->get_cart() as $cart_item ) {

            // Get the product categories for the current item
            $item_categories = wp_get_post_terms( $cart_item['product_id'], 'product_cat' );

            // Iterating through each product categories defined for the item
            foreach($item_categories as $item_category){
                if( $item_category->term_id == $special_category ) {
                    $minimumCheck = false;
                    break;
                }
                else {
                    $minimumCheck = true;
                }
            }

            // The cart total without taxes:
            $cart_total_excl_taxes =  WC()->cart->subtotal_ex_tax;
        }

        if ( $minimumCheck == 'true' && $cart_total_excl_taxes <= $minimum_cart_total) {

            // Displays the message notice
            wc_add_notice( sprintf( '<strong>A Minimum of %s %s excl. TAX is required category before checking out.</strong>'
                .'<br />Current cart\'s total: %s %s excl. TAX',
                $minimum_cart_total,
                get_option( 'woocommerce_currency'),
                $cart_total_excl_taxes,
                get_option( 'woocommerce_currency') ),
                'error' );
        }
    }
}

这段代码已经过测试，这次可以正常工作……
