php - 如何更改购物车中的可变产品价格还删除删除 Woocommerce 中的特定产品表单购物车

问题描述

在我的网站上，我在购物车中添加了一个可变产品。当时，另一个可变产品也添加到该购物车中，该产品是礼品产品。现在我想将礼品可变产品价格更改为 0，它仅在满足条件时才起作用在购物车中提供礼物的产品。此外，我想通过单击提供礼物的产品来删除两个相同的产品形式。下面我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;
        }
    }
}

解决方案

可以根据此解决方案添加礼品 -在 woocommerce 中买一送一，无需优惠券代码。

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' );

如果您想降低礼品的价格，请添加此选项。

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' );
