问题描述
我无法在第二次购买时超越价格。
I am unable to override price on second time purchase.
用例将是:如果用户已经购买了产品 944,则下一次订购的价格为0。
The use case would be: If a user has already bought product "944" then the price would be 0 for next time orders.
意思是,客户仅需为该特定产品的第一笔订单付款,下一笔订单即可免费。
Meaning, the customer would pay only for first order of that specific product and it would be free for next orders.
这里是我的代码:
// Enter the ID of the product that shouldn't be purchased again
$no_repeats_id = 944;
$no_repeats_product = wc_get_product( $no_repeats_id );
// Get the current product to check if purchasing should be disabled
global $product;
if ( $no_repeats_product->is_type( 'variation' ) ) {
// Bail if we're not looking at the product page for the non-purchasable product
if ( ! $no_repeats_product->parent->id === $product->id ) {
return;
}
// Render the purchase restricted message if we are
if ( wc_customer_bought_product( wp_get_current_user()->user_email, get_current_user_id(), $no_repeats_id ) ) {
sv_render_variation_non_purchasable_message( $product, $no_repeats_id );
}
} elseif ( $no_repeats_id === $product->id ) {
if ( wc_customer_bought_product( wp_get_current_user()->user_email, get_current_user_id(), $no_repeats_id ) ) {
// Create your message for the customer here
add_action( 'woocommerce_before_calculate_totals', 'add_custom_price' );
add_action( 'woocommerce_before_calculate_totals', 'add_custom_price' );
function add_custom_price( $cart_object ) {
$custom_price = 10; // This will be your custome price
$target_product_id = 944;
foreach ( $cart_object->cart_contents as $value ) {
if ( $value['product_id'] == $target_product_id ) {
$value['data']->price = $custom_price;
}
/*
// If your target product is a variation
if ( $value['variation_id'] == $target_product_id ) {
$value['data']->price = $custom_price;
}
*/
}
}
}
}
}
add_action( 'woocommerce_single_product_summary', 'sv_purchase_disabled_message', 31 );
推荐答案
这是使其在woocommerce中起作用的方法3
Here is the way to make it work in woocommerce 3+ too:
add_action( 'woocommerce_before_calculate_totals', 'conditionally_change_cart_items_price', 10, 1 );
function conditionally_change_cart_items_price( $cart_object ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
return;
// Set Here your targeted product ID
$targeted_product_id = 944;
// Set Here your custom price (1st purshase)
$custom_price = 10; // First purshase for product ID 944
// Detecting if customer has already bought The targeted product (944)
if( is_user_logged_in() ){
$customer = wp_get_current_user();
$customer_id = $customer->ID; // customer ID
$customer_email = $customer->email; // customer email
if( wc_customer_bought_product( $customer_email, $customer_id, $targeted_product_id) )
$custom_price = 0; // Set to 0 for other purchases (product ID 944)
}
foreach ( $cart_object->get_cart() as $cart_item ) {
// When targeted product is in cart we change the price
if ( $cart_item['product_id'] == $targeted_product_id ) {
// Woocommerce 3+ compatibility
if ( version_compare( WC_VERSION, '3.0', '<' ) )
$cart_item['data']->price = $custom_price;
else
$cart_item['data']->set_price( $custom_price );
}
}
}
代码进入function.php子主题文件(或主题文件)或任何插件文件中。
Code goes in function.php file of your active child theme (or theme) or also in any plugin file.
此代码已经过测试,即使在WooCommerce 3+中也可以使用
This code is tested and works even in WooCommerce 3+
