我可以在某些特定产品中更改WooCommerce数量吗?

要更改数量,请参阅该代码。在这里您重新访问的代码:

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:现在更改特定产品的数量,您需要使用此woocommerce_before_calculate_totals动作挂钩中的自定义函数:

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
        }
    }
}

代码放在活动子主题(或活动主题)的function.php文件中。

经过测试和工作
