根据Woocommerce中购物车的数量增加产品价格的额外成本

基于Woocommerce change prices for a certain country,我试图在产品价格上增加一笔额外费用,该费用必须除以购物车数量。

add_filter('woocommerce_get_price', 'return_custom_price', $product, 2);

function return_custom_price($price, $product) {    
    global $post, $woocommerce;
    // Array containing country codes
    $container = 3000;
    $county = array('GR');
    // Get the post id 
    $post_id = $post->ID;

    $cart_tot = $woocommerce->cart->cart_contents_count;
    // Amount to increase by
    $amount = ($container / $cart_tot);
    // If the customers shipping country is in the array and the post id matches
    if ( in_array( $woocommerce->customer->get_shipping_country(), $county ) && ( $post_id == '1151' || $post_id == '1152' ) ){
        // Return the price plus the $amount
       return $new_price = $price + $amount;
    } else {
        // Otherwise just return the normal price
        return $price;
    }
} 

问题是我遇到错误,但我不知道如何解决。 警告:被零除

当我使用echo $ woocommerce-> cart-> cart_contents_count;时,它显示购物车项目计数,但连续显示多次。…

感谢您的帮助。

自Woocommerce 3起,不赞成使用钩子woocommerce_get_price并已将其替换。而且代码真的过时了,充满了错误和错误。

您不能真正根据购物车更改产品价格,因为它总是会出错,并且不是处理所需商品的正确方法。

无论如何,这里都是您重新访问的代码,但您不应该使用它 (请参阅下面的另一种方法)

add_filter( 'woocommerce_product_get_price', 'custom_specific_product_prices', 10, 2 );
function custom_specific_product_prices( $price, $product ) {
    // Exit when cart is empty
    if( WC()->cart->is_empty() )
        return $price; // Exit

    ## ----- Your settings below ----- ##

    $countries   = array('GR'); // Country codes
    $product_ids = array('1151', '1152'); // Product Ids
    $container   = 3000; // Container cost

    ## ------------------------------- ##

    if( ! in_array( $product->get_id(), $product_ids ) )
        return $price; // Exit

    $cart_items_count = WC()->cart->get_cart_contents_count();
    $shipping_country = WC()->customer->get_shipping_country();

    // If the customers shipping country is in the array and the post id matches
    if ( in_array( $shipping_country, $countries ) ) {
        // Return the price plus the $amount
        $price +=  $container / $cart_items_count;
    }

    return $price;
}

代码进入您的活动子主题(或活动主题)的function.php文件中。经过测试,可以正常工作。


您可以做的是添加“容器”费用:

add_action( 'woocommerce_cart_calculate_fees', 'add_container_fee', 10, 1 );
function add_container_fee( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return; // Exit

    ## ----- Your settings below ----- ##

    $countries   = array('GR'); // Country codes
    $product_ids = array('1151', '1152'); // Product Ids
    $container   = 3000; // Container cost

    ## ------------------------------- ##

    $shipping_country = WC()->customer->get_shipping_country();
    $items_found      = false;

    if ( ! in_array( $shipping_country, $countries ) )
        return; // Exit

    foreach( $cart->get_cart() as $cart_item ) {
        if ( array_intersect( array( $cart_item['variation_id'], $cart_item['product_id'] ), $product_ids ) )
            $items_found = true; // Found
    }

    if ( $items_found )
        $cart->add_fee( __('Container fee'), $container );
}
