Question

我有一个产品1€并使用e GET参数在运行时更改价格：

http://url/warenkorb/?add-to-cart=1539&price=18.45

这个改变不是篮子里的价格（仍然是1欧元）

如何实现这一目标。

我使用以下钩子：

add_filter( 'woocommerce_add_cart_item', 'my_woocommerce_add_cart_item', 5, 1 );
function my_woocommerce_add_cart_item( $cart_item ) {

if(get_post_meta( $cart_item['data']->id, 'isConfigurableProduct', true)=='1')
{   
    if(isset($_GET['price']))
    {
        $price=$_GET['price'];//keep it simpel for testing
        $cart_item['data']->set_price( $price );
        $_SESSION[$cart_item['data']->id]=$price;
    }
    else
    {
        $cart_item['data']->set_price($_SESSION[$cart_item['data']->id]);   
    }
}
return $cart_item;
}

Answer 1

使用WooCommerce 2.5，我发现这是一个由两部分组成的过程。第一步是通过woocommerce_add_cart_item过滤器添加到购物车时更改定价的运行时显示。第二部分是通过woocommerce_get_cart_item_from_session过滤器设置在结账时读取的持久会话数据。

add_filter( 'woocommerce_add_cart_item' , 'set_woo_prices');
add_filter( 'woocommerce_get_cart_item_from_session',  'set_session_prices', 20 , 3 );

function set_woo_prices( $woo_data ) {
  if ( ! isset( $_GET['price'] ) || empty ( $_GET['price'] ) ) { return $woo_data; }
  $woo_data['data']->set_price( $_GET['price'] );
  $woo_data['my_price'] = $_GET['price'];
  return $woo_data;
}

function  set_session_prices ( $woo_data , $values , $key ) {
    if ( ! isset( $woo_data['my_price'] ) || empty ( $woo_data['my_price'] ) ) { return $woo_data; }
    $woo_data['data']->set_price( $woo_data['my_price'] );
    return $woo_data;
}

将my_price设置为woocommerce_add_cart_item中woo_data的一部分，允许稍后通过会话价格过滤器检索该数据。更安全的方法是不在URL中传递价格并直接设置它以避免URL价格操纵。

在将Store Locator Plus连接到WooCommerce的实际实现中，我将每个WooCommerce产品的每位置定价数据存储在内部表中，并且在此示例中仅设置/检索位置ID以代替“my_price”。内部方法用于在上述两种方法中从数据表中获取设定价格，使用位置ID作为查找，只留下公共URL，其位置ID不允许他们修改定价。

首先，我想提醒您，如果您在add_to_cart链接的网址中使用价格可能会使您的商店容易受到攻击。如果你在产品元中使用它会更安全。无论如何，我向您展示了如何从网址设置价格的代码。

add_filter( 'woocommerce_add_cart_item', 'c_other_options_add_cart_item', 20, 1 );
function c_other_options_add_cart_item( $cart_item ) {

    if (isset($cart_item['_other_options'])) :
        if( isset($cart_item['_other_options']['product-price']) )
            $extra_cost = floatval($cart_item['_other_options']['product-price']);

        $cart_item['data']->adjust_price( $extra_cost );
        // here the real adjustment is going on...

    endif;

    return $cart_item;

}

add_filter( 'woocommerce_add_cart_item_data', 'c_other_options_add_cart_item_data', 10, 2 );
function c_other_options_add_cart_item_data($cart_item_meta, $product_id){
    global $woocommerce;

    $product = new WC_Product( $product_id);
    $price = $product->price;

    if(empty($cart_item_meta['_other_options']))
        $cart_item_meta['_other_options'] = array();

    $cart_item_meta['_other_options']['product-price'] = esc_attr($_REQUEST['price']) - $price;

// as woocommerce allows to adjust the price (i don't know if there is any way to reset it, but this procedure works), we need to return the adjustable price 

    return $cart_item_meta;
}

它不适合我，我修改为修改参数传递的价格

spainbox.com/carro/?add-to-cart=28792&shippingprice=141

产品的价格为1欧元，我需要添加到购物车这个产品，因为它的服务将有运费的价格

<?
add_filter( 'woocommerce_add_cart_item', 'c_other_options_add_cart_item', 20, 1 );
function c_other_options_add_cart_item( $cart_item ) {

    if (isset($cart_item['_other_options'])) :
        if( isset($cart_item['_other_options']['product-price']) )
            $extra_cost = floatval($cart_item['_other_options']['product-price']);

        $cart_item['data']->adjust_price( $extra_cost );
        // here the real adjustment is going on...

    endif;

    return $cart_item;

}

add_filter( 'woocommerce_add_cart_item_data', 'c_other_options_add_cart_item_data', 10, 2 );
function c_other_options_add_cart_item_data($cart_item_meta, $product_id){
    global $woocommerce;

    $product = new WC_Product( $product_id);
    $price = $product->price;

    if(empty($cart_item_meta['_other_options']))
        $cart_item_meta['_other_options'] = array();

    $cart_item_meta['_other_options']['product-price'] = esc_attr($_REQUEST['shippingprice']);

// as woocommerce allows to adjust the price (i don't know if there is any way to reset it, but this procedure works), we need to return the adjustable price

    return $cart_item_meta;
}
?>

woocommerce改变价格，同时加入购物车
