在Woocommerce中将购物车项目的价格替换为自定义字段值 [英] Replace the price of the cart item with a custom field value in Woocommerce

问题描述

在WooCommerce中，我试图用自定义字段价格替换购物车项目的价格.

In WooCommerce I am trying to replace the price of the cart items inwith a custom field price.

这是我的代码:

function custom_cart_items_price ( $cart_object ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

    foreach ( $cart_object->get_cart() as $cart_item ) {

        // get the product id (or the variation id)
        $id = $cart_item['data']->get_id();

        // GET THE NEW PRICE (code to be replace by yours)
        $new_price = (int)get_post_meta( get_the_ID(), '_c_price_field', true ); // <== Add your code HERE

        // Updated cart item price
        $cart_item['data']->set_price( $new_price ); 
    }
}

add_filter( 'woocommerce_before_calculate_totals', 'custom_cart_items_price');

但是它不起作用.我在做什么错了?

But it doesn't work. What I am doing wrong?

任何帮助将不胜感激.

推荐答案

如果在购物车中将 get_the_ID()与 get_post_meta()一起使用，则此方法无效.您应该改用:

It doesn't work if you use get_the_ID() with get_post_meta() in cart. You should use instead:

add_action( 'woocommerce_before_calculate_totals', 'custom_cart_items_price');
function custom_cart_items_price ( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
         return;

    if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
        return;

    foreach ( $cart->get_cart() as $cart_item ) {

         // get the product id (or the variation id)
         $product_id = $cart_item['data']->get_id();

         // GET THE NEW PRICE (code to be replace by yours)
         $new_price = get_post_meta( $product_id, '_c_price_field', true ); 

         // Updated cart item price
         $cart_item['data']->set_price( floatval( $new_price ) ); 
    }
}

代码进入您的活动子主题(或活动主题)的function.php文件中.

现在应该可以了
