我希望在woocommerce购物车页面中获取[due_payment]数组的值，并且每次为每个产品更改[1a0421df7401f1b79616141d5a4e223a]根名称我如何获得此帮助？我正在使用租赁和预订woocommerce插件和产品类型是woocommerce租赁产品我是阵列和插件定制的初学者我也搜索，但我没有，我知道如何得到[due_payment]的价值阵列。请指导我如何做到这一点

Answer 1

您需要再申请一个foreach()，如下所示： -

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'];‌​‌
    }
}

注意： - 你可以缩减这两行： -

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

成为一个： -

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

Answer 2

这是使用数组键执行此操作的另一种方法。不需要2个foreach循环。

$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。

$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'];‌​‌
}
