我想在woocommerce购物车页面中获取[due_payment]数组的值和[1a0421df7401f1b79616141d5a4e223a]每次更改每个产品的根名称如何获得此帮助？我正在使用租赁和预订woocommerce插件，产品类型是woocommerce中的租赁产品我是阵列和插件定制的初学者，我也在搜索，但我不知道如何获得[due_payment]阵列的价值。请指导我如何做到这一点

您需要再申请一个foreach，如下所示：-

注意：-您可以缩短这两条线：-

global $woocommerce; 
$items = $woocommerce->cart->get_cart();    
foreach($items as $item => $values) {  
    foreach($values as $arr){ //apply one-more foreach()
      echo $arr['rental_data']['rental_days_and_costs']['due_payment'];‌​‌
    }
}

合二为一：-

global $woocommerce; 
$items = $woocommerce->cart->get_cart();

这里有另一种方法，使用数组键。不需要2个foreach循环

$items = WC()->cart->get_cart(); 

$cart_items = WC()->cart->get_cart(); 
foreach( $cart_items as $cart_item_key => $cart_item ) {  
      echo $cart_items[$cart_item_key]['rental_data']['rental_days_and_costs']['due_payment'];‌​‌
}

还有另一种方法。这次没有foreach循环

$items = WC()->cart->get_cart(); 

$cart_items = WC()->cart->get_cart(); 
foreach( $cart_items as $cart_item_key => $cart_item ) {  
      echo $cart_items[$cart_item_key]['rental_data']['rental_days_and_costs']['due_payment'];‌​‌
}

那就使用foreach吧。在我使用foreach的地方，请指导meglobal$woocommerce$items=$woocommerce->cart->get\u cart；foreach$items as$item=>$values{？>我使用这样的方法来获取数组foreach$values as$arr{echo$arr['rental_data']['rental_days_and_costs']['due_payment']；}

$cart_items = WC()->cart->get_cart();
if ( is_array( $cart_items ) && !empty( $cart_items ) ) {
    $cart_item_keys = array_keys($cart_items);
    echo $cart_items[$cart_item_keys[0]]['rental_data']['rental_days_and_costs']['due_payment'];‌​‌
}
