更改 woocommerce 中特定产品的购物车商品数量

Question

我可以更改某些特定产品的 WooCommerce 数量吗？

我试过：

global $woocommerce;
    $items = $woocommerce->cart->get_cart();
    foreach($items as $item => $values) { 
        $_product = $values['data']->post; 
        echo "<b>".$_product->post_title.'</b>  <br> Quantity: '.$values['quantity'].'<br>'; 
        $price = get_post_meta($values['product_id'] , '_price', true);
        echo "  Price: ".$price."<br>";
    }

如何获取购物车中的特定产品编号？

Answer 1

要更改数量，请参阅该代码之后。这是您重新访问的代码：

foreach( WC()->cart->get_cart() as $cart_item_key => $cart_item ) { 
    $product = $cart_item['data']; // Get an instance of the WC_Product object
    echo "<b>".$product->get_title().'</b>  <br> Quantity: '.$cart_item['quantity'].'<br>'; 
    echo "  Price: ".$product->get_price()."<br>";
}

已更新：现在要更改特定产品的数量，您需要使用挂钩在[=12=中的自定义函数] 动作挂钩：

add_action('woocommerce_before_calculate_totals', 'change_cart_item_quantities', 20, 1 );
function change_cart_item_quantities ( $cart ) {
    if ( is_admin() && ! defined( 'DOING_AJAX' ) )
        return;

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

    // HERE below define your specific products IDs
    $specific_ids = array(37, 51);
    $new_qty = 1; // New quantity

    // Checking cart items
    foreach( $cart->get_cart() as $cart_item_key => $cart_item ) {
        $product_id = $cart_item['data']->get_id();
        // Check for specific product IDs and change quantity
        if( in_array( $product_id, $specific_ids ) && $cart_item['quantity'] != $new_qty ){
            $cart->set_quantity( $cart_item_key, $new_qty ); // Change quantity
        }
    }
}

代码进入活动子主题（或活动主题）的 function.php 文件。
