【问题描述】：

我对 PHP 和 WordPress 还是很陌生，我正在努力正确地对一个包含多个 woocommerce 订单项的数组进行 json_encode。数组的“订单项”部分是我无法弄清楚的部分，因为需要根据订单中的 SKU 数量（即 1、2、3 等）动态创建结构。

下面是我需要创建的数组的动态部分的示例。

 $product_list_example_array =
     array (
      'items' => array (
                 0 => 
                 array (
                   'quantity' => 1,
                   'sku' => 'sample string 2',
                   'description' => 'sample string 3',
                   'price' => 4,
                 ),
                 1 => 
                 array (
                   'quantity' => 1,
                   'sku' => 'sample string 2',
                   'description' => 'sample string 3',
                   'price' => 4,
                 ),
           ),
     );

为此，我创建了变量 $product_list，它根据产品数量为我提供了完美格式化的数组。当我回显 $product_list 时，它看起来与上面的示例完全一样，都在一行中。

所以我认为会很好用......但是，当我将 $product_list 放入更大的数组中，然后使用 json_encode 将该数组转换为 json 时，瞧，我的 $product_list 变量并没有兑换。最终json中出现的$product_list还是数组格式！

foreach( $order_item as $product ) {
$product_name = $product['name'];
$product_qty = $product['qty'];
$product_id = $product['product_id'];
$product_price = $product['line_total'];
$product_sku = get_post_meta( $product_id, '_sku', true);

    $prodct_list_name[] = '['. $items_number++ .']=> array (\'quantity\' => '. $product_qty .',\'sku\' => '. $product_sku .',\'description\' => '. $product_name .'\'price\' => '. $product_price .')';


}
$product_list = implode( ',', $prodct_list_name );

echo $product_list;

$args = array (
  'apiKey' => $API_KEY,
  'booking' => 
  array (
   //this is the part of the array where I insert my $product_list array object
    'items' => 
    array ( $product_list 
    ),
    'pickupDetail' => 
    array (
      'address' => $Pickup_Address,
    ),
    'dropoffDetail' => 
    array (
      'name' => $Shipping_Name,
      'phone' => $Phone_Number,
      'email' => $Shipping_Email,
      'description' => $Order_Notes,
      'address' => $Shipping_Address,
    ),
  ),
);
//display the json
    $json_data =  json_encode($args);
    echo $json_data;

最后 json 如下所示。请查看 json 并查看除 $product_list 部分之外的整个数组是如何正确编码的。如果有办法解决这个问题或完全不同，我真的很高兴。

{"apiKey":API_KEY,"booking":{"items":["[0]=> array ('quantity' => 1,'sku' => CAN-BR,'description' => Candle | Black Raspberry'price' => 0),[1]=> array ('quantity' => 1,'sku' => ,'description' => Candle | Fig & Melon'price' => 21.95),"],"pickupDetail":{"address":"Pickup Address"},"dropoffDetail":{"name":"Cusomter Name","phone":"5555555555","email":"test@email.com","description":"Order Notes (order_comments)","address":"Delivery Address"}}}

【解决方案1】：

因为您将其用作字符串而不是数组。使用以下代码将$product_list 存储为数组：

$product_list = array();
foreach( $order_item as $product ) {
    $product_name = $product['name'];
    $product_qty = $product['qty'];
    $product_id = $product['product_id'];
    $product_price = $product['line_total'];
    $product_sku = get_post_meta( $product_id, '_sku', true);

    $product_list[$items_number++] = array ('quantity' => $product_qty,'sku' => $product_sku ,'description' => $product_name, 'price' => $product_price );
}
// $product_list = implode( ',', $prodct_list_name );

// echo $product_list;

$args = array (
  'apiKey' => $API_KEY,
  'booking' => 
  array (
   //this is the part of the array where I insert my $product_list array object
    'items' => 
    array ( $product_list 
        ),
    'pickupDetail' => 
    array (
      'address' => $Pickup_Address,
      ),
    'dropoffDetail' => 
    array (
      'name' => $Shipping_Name,
      'phone' => $Phone_Number,
      'email' => $Shipping_Email,
      'description' => $Order_Notes,
      'address' => $Shipping_Address,
      ),
    ),
  );
//display the json
$json_data =  json_encode($args);
echo $json_data;
