在我的网站上,我将一个可变产品添加到购物车中.当时,另一个可变产品也添加到该购物车中,该产品为礼品产品.现在,我想将礼品可变产品价格更改为0,仅当条件满足购物车中提供礼物的产品.我也想通过单击提供礼物的产品来删除相同的两种产品形式.下面的代码对我不起作用.

add_action( 'woocommerce_before_calculate_totals', 'change_custom_price' );

function change_custom_price( $cart_object ) {
    $custom_price = 0; // This will be your custome price  
    $gift_variation_id = 2046;
    foreach ( $cart_object->cart_contents as $value ) {
        if ( $value['variation_id'] == $gift_variation_id ) {
            $value['data']->price = $custom_price;
        }
    }
}

解决方法:

可以根据此解决方案添加礼品-Buy one get one in woocommerce with out coupon code.

您可以将以下内容添加到主题的“ functions.php”中,以删除其他产品自动添加的礼品.

function remove_gift_product($cart_item_key) {
    global $woocommerce;
    $cat_in_cart = false;
    $coupon_in_cart = false;

    $autocoupon = array( 123411 ); // variation ids of products that offers gifts
    $freecoupon =  array( 2046 ); // variation ids of products that are gift coupons

    foreach ( $woocommerce->cart->cart_contents as $key => $values ) {      
        if( in_array( $values['variation_id'], $autocoupon ) ) {  
            $cat_in_cart = true;                
        }       
    }

    if ( !$cat_in_cart ) {          
        foreach ($woocommerce->cart->get_cart() as $cart_item_key => $cart_item) {
            if ( in_array( $cart_item['variation_id'], $freecoupon )) {             
                $woocommerce->cart->remove_cart_item($cart_item_key);
            }
        } 
    }
}
add_action( 'woocommerce_cart_item_removed', 'remove_gift_product' );

如果要降低礼品价格,请添加此标签.

function add_discount_price( $cart_object ) {
    global $woocommerce;
    $cat_in_cart = false;

    $autocoupon = array( 123411 ); // variation ids of products that offers gifts
    $freecoupon =  array( 2046 ); // variation ids of products that are gift coupons

    foreach ( $woocommerce->cart->cart_contents as $key => $values ) {      
        if( in_array( $values['variation_id'], $autocoupon ) ) {  
            $cat_in_cart = true;                
        }       
    }
    if ( $cat_in_cart ) {
        $custom_price = 0; // This will be your custome price     
        foreach ($woocommerce->cart->get_cart() as $cart_item_key => $cart_item) {
            if ( in_array( $cart_item['variation_id'], $freecoupon )) {
                 $cart_item['data']->set_price($custom_price);
            }        
        }
    }
}

add_action( 'woocommerce_before_calculate_totals', 'add_discount_price' );
