【问题描述】:
我正在使用动态定价来打折一件物品以免费赠送另一件物品,我想避免让客户将免费产品作为单独的步骤添加,而让系统添加它。
我从 snippet 开始,但当项目存在时我无法让它工作
这是我目前得到的:
<?php
function add_product_to_cart() {
if ( ! is_admin() ) {
global $woocommerce;
$product_id_gift = 2287;
$found = false;
$product_id = 30;
$incart_free = false;
foreach($woocommerce->cart->get_cart() as $cart_item_key => $values ) {
$_product = $values['data'];
if ( $_product->id == $product_id ){
$incart_free = true;
}
return $incart_free;
}
if( $incart_free == true ) {
//check if product already in cart
if ( sizeof( $woocommerce->cart->get_cart() ) > 0 ) {
foreach ( $woocommerce->cart->get_cart() as $cart_item_key => $values ) {
$_product = $values['data'];
if ( $_product->id == $product_id_gift )
$found = true;
}
// if product not found, add it
if ( $found != true )
$woocommerce->cart->add_to_cart( $product_id_gift );
} else {
// if no products in cart, add it
$woocommerce->cart->add_to_cart( $product_id_gift );
}
}
}
}
add_action( 'init', 'add_product_to_cart' );
?>
谢谢!
