PHP 在数组变量中添加条件(WooCommerce API)

Question

以 WooCommerce API 文档中的以下代码为例。我想做的是在数组中添加一些 if 条件。例如，我希望基于某些 if 条件，将 payment_details 数组作为 $data 的一部分。这可能吗？怎么办？

<?php
$data = [
    'order' => [
        'payment_details' => [
            'method_id' => 'bacs',
            'method_title' => 'Direct Bank Transfer',
            'paid' => true
        ],
        'billing_address' => [
            'first_name' => 'John',
            'last_name' => 'Doe',
            'address_1' => '969 Market',
            'address_2' => '',
            'city' => 'San Francisco',
            'state' => 'CA',
            'postcode' => '94103',
            'country' => 'US',
            'email' => '<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="1973767177377d767c597c61787469757c377a7674" rel="noreferrer noopener nofollow">[email protected]</a>',
            'phone' => '(555) 555-5555'
        ],
        'shipping_address' => [
            'first_name' => 'John',
            'last_name' => 'Doe',
            'address_1' => '969 Market',
            'address_2' => '',
            'city' => 'San Francisco',
            'state' => 'CA',
            'postcode' => '94103',
            'country' => 'US'
        ],
        'customer_id' => 2,
        'line_items' => [
            [
                'product_id' => 546,
                'quantity' => 2
            ],
            [
                'product_id' => 613,
                'quantity' => 1,
                'variations' => [
                    'pa_color' => 'Black'
                ]
            ]
        ],
        'shipping_lines' => [
            [
                'method_id' => 'flat_rate',
                'method_title' => 'Flat Rate',
                'total' => 10
            ]
        ]
    ]
];

print_r($woocommerce->post('orders', $data));
?>

重点是，我不想再次定义整个数组，而是想在此处放置一个 if 条件:

'订单'=> [

如果($付款='xyz'){

'payment_details' => [
    'method_id' => 'bacs',
    'method_title' => 'Direct Bank Transfer',
    'paid' => true
],

} 否则{

'payment_details' => [
    'method_id' => 'monopoly',
    'method_title' => 'Monopoly',
    'paid' => true
],

}

是否可以使用点等于连接数组？ .= 谢谢。

Answer 1

“payment_details”已经是 $data 的一部分。

要获取它，请使用:

$paymentDetails = $data['order']['payment_details'];

然后你可以用以下方式显示它:

echo $paymentDetails['method_title'];

如果你想使用if条件:

if ($paymentDetails['method_title'] === 'Monopoly money') {
    echo 'That will not work';
}

要更改付款详细信息:

$data['order']['payment_details']['method_title'] = 'Changed';

或

$data['order']['payment_details'] = ['method_title' => 'something', 'method_id' => 5, 'paid' => false];
