使用 PHP 构建 Mandrill 'to' 数组

Question

我想用 Mandrill 发送多封电子邮件，但不知道如何构建 'to' 数组。从他们的docs 来看，它看起来像这样（并且正在工作）：

'from_name' => 'My Name',
'to' => array(
    array(
        'email' => 'first@example.com',
        'name' => 'First Recipient',
        'type' => 'to'
    ),
    array(
        'email' => 'second@example.com',
        'name' => 'Second Recipient',
        'type' => 'to'
    )
),
'headers' => array('Reply-To' => 'me@example.org'),

我的 PHP 代码是：

foreach ($users as $user) {
    $to[] = array(
        array(
            'email' => 'first@example.com',
            'name' => 'First Recipient',
            'type' => 'to'
        ),
        array(
            'email' => 'second@example.com',
            'name' => 'Second Recipient',
            'type' => 'to'
        )
}

但是当我用$to插入收件人时，肯定有问题。

'from_name' => 'My Name',
'to' => $to,
'headers' => array('Reply-To' => 'me@example.org'),

Mandrill 不发送任何内容，结果是一个空数组（这意味着没有发送任何电子邮件）。两个数组对我来说看起来都一样。是吗？

供参考，完整代码如下：

public function notifySubscribers() {

    // Get page
    $scheduledPage = $from_db_query;

    // $users = wire('users')->find('!login_start>=today, !login_end<=today, limit=999');
    // foreach($users as $u) {
    //  if ( $u->hasPermission('page-view', $scheduledPage) ) {
    //      $recipients[] = $u;
    //  }
    // }
    $to = array(
                array(
                    'email' => 'first@example.com',
                    'name' => 'First Recipient',
                    'type' => 'to'
                ),
                array(
                    'email' => 'second@example.com',
                    'name' => 'Second Recipient',
                    'type' => 'to'
                )
            );

    // Returns array with stats from mailing
    $dispatched = $this->dispatchMail($scheduledPage->title, $scheduledPage->body, $scheduledPage->files->first(), $to);

}

Answer 1

在你的循环中你正在这样做：

$to[] = array(
    array(
        'email' => 'first@example.com',
        'name' => 'First Recipient',
        'type' => 'to'
    ),
 );

请记住，这意味着您将所有内容都推送到 $to 数组中。但是这里你推送的是一个两级数组，实际上你只想推送一个级别：

$to[] = array(
    'email' => 'first@example.com',
    'name' => 'First Recipient',
    'type' => 'to',
 );

Mandrill 无法理解你在做什么，因为它看到了这个：

array(
    array(
        array(
            'email' => 'first@example.com',
            'name' => 'First Recipient',
            'type' => 'to'
        ),
    ),
    array(
        array(
            'email' => 'second@example.com',
            'name' => 'Second Recipient',
            'type' => 'to'
        )
    ),
)

太多关卡了！
