【问题描述】：

我正在尝试在 Braintree 交易中为购物篮中的每个产品包含多个 lineItems。

下面的交易成功并且按预期工作，只添加了一项作为lineItem。

$result = Braintree_Transaction::sale([
    'orderId' => $hash,
    'amount' => $this->basket->subTotal() + $this->basket->delivery(),
    'paymentMethodNonce' => $request->getParam('payment_method_nonce'),
    'shippingAmount' => $this->basket->delivery(),
    'discountAmount' => '0',
    'shipsFromPostalCode' => '7008',
    'taxExempt' => true,
    'purchaseOrderNumber' => $hash1,
    'options' => [
        'submitForSettlement' => true,
    ],
    'customer' => [
        'firstName' => $request->getParam('name'),
        'email' => $request->getParam('email'),
    ],
    'shipping' => [
        'firstName' => $request->getParam('name'),
        'streetAddress' => $request->getParam('address1'),
        'locality' => $request->getParam('city'),
        'postalCode' => $request->getParam('postal_code'),
        'countryCodeAlpha3' => 'AUS',
    ],
    'lineItems' => [
        [
            'quantity' => $product->quantity, 
            'name' => $product->title, 
            'kind' => 'debit', 
            'unitAmount' => $product->price, 
            'totalAmount' => $product->price * $product->quantity
        ],
    ]
]);

但是，当我尝试将所有产品包括在篮子中时，如下所示

$basketProducts = $this->basket->all();

if($basketProducts){
    $lineItems = '';
foreach ($basketProducts as $product){
    $lineItems .= <<<EOD
    [
        'quantity' => $product->quantity, 
        'name' => $product->title, 
        'kind' => 'debit', 
        'unitAmount' => $product->price, 
        'totalAmount' => $product->price * $product->quantity
    ],
EOD;
}
}

$result = Braintree_Transaction::sale([
    'orderId' => $hash,
    'amount' => $this->basket->subTotal() + $this->basket->delivery(),
    'paymentMethodNonce' => $request->getParam('payment_method_nonce'),
    'shippingAmount' => $this->basket->delivery(),
    'discountAmount' => '0',
    'shipsFromPostalCode' => '7008',
    'taxExempt' => true,
    'purchaseOrderNumber' => $hash1,
    'options' => [
        'submitForSettlement' => true,
    ],
    'customer' => [
        'firstName' => $request->getParam('name'),
        'email' => $request->getParam('email'),
    ],
    'shipping' => [
        'firstName' => $request->getParam('name'),
        'streetAddress' => $request->getParam('address1'),
        'locality' => $request->getParam('city'),
        'postalCode' => $request->getParam('postal_code'),
        'countryCodeAlpha3' => 'AUS',
    ],
    'lineItems' => [
        $lineItems
    ]
]);

我收到此错误消息：

类型：InvalidArgumentException
消息：无效键：lineItems[ [ 'quantity' => 1, 'name' => Apricot Chicken, 'kind' => 'debit', 'unitAmount' => 9.8, 'totalAmount' => 9.8 * 1 ],]
文件：C:\wamp64\www\vendor\braintree\braintree_php\lib\Braintree\Util.php
线路：396

因此，它似乎从该变量中提取了正确的数据，只是 Braintree 将其检测为无效。
我错过了什么吗？任何帮助将不胜感激！

【解决方案1】：

您不能在lineItems 中为Braintree_Transaction::sale() 传递字符串，因为它是一个数组。我解决这个问题的方法是使$lineItems 成为一个数组，然后使用array_push 将每个$product 的新数组推入$lineItems

完整示例 ->

$basketProducts = $this->basket->all();

if($basketProducts){    
    $lineItems = array();   
foreach ($basketProducts as $product){
    array_push($lineItems, array(
        'quantity' => $product->quantity, 
        'name' => $product->title, 
        'kind' => 'debit', 
        'unitAmount' => $product->price, 
        'totalAmount' => $product->price * $product->quantity,
        'productCode' => $product->id)
    );
}
}

$sale = array(
    'orderId' => $hash,
    'amount' => $this->basket->subTotal() + $this->basket->delivery(),
    'paymentMethodNonce' => $request->getParam('payment_method_nonce'),
    'shippingAmount' => $this->basket->delivery(),
    'discountAmount' => '0',
    'shipsFromPostalCode' => '7008',
    'taxExempt' => true,
    'purchaseOrderNumber' => $hash1,
    'options' => array(
        'submitForSettlement' => true,
    ),
    'customer' => array(
        'firstName' => $request->getParam('name'),
        'email' => $request->getParam('email'),
    ),
    'shipping' => array(
        'firstName' => $request->getParam('name'),
        'streetAddress' => $request->getParam('address1'),
        'locality' => $request->getParam('city'),
        'postalCode' => $request->getParam('postal_code'),
        'countryCodeAlpha3' => 'AUS',
    ),
    'lineItems' => $lineItems
);

$result = Braintree_Transaction::sale($sale);
