Question

我需要回复收到的电子邮件，包括其中包含的附件。我编写了这段代码，但由于某些原因，当我检查调试日志和mandrill API日志时，附件并未包含在请求中。哪里有我的错？

if ($message['attachments']) 
    {

        $mail= 
            [
                'html' => $mail->msg->html,
                'text' => $mail->msg->text,
                'subject' => $mail->msg->subject,
                'from_email' => 'test@test.com',
                'from_name' => $mail->msg->from_name,
                'to' => [
                    [
                        'email' => 'test@test.com',
                        'name' => 'test@test.com',
                        'type' => 'to'
                    ]
                ],
                'headers' => [
                    'Reply-To' => $mail->msg->from_email
                ],
            ];
            //just some sample data for testing
            foreach ($message['attachment'] as $attachment) 
                {
                    $mail['attachments']['name'] ='sample.png';
                    $mail['attachments']['type'] ='image/png';
                    $mail['attachments']['content'] ='iVBORw0KGgoAAAANSUhEUgAAABwAAAASCAMAAAB/2U7WAAAABlBMVEUAAAD///+l2Z/dAAAASUlEQVR4XqWQUQoAIAxC2/0vXZDrEX4IJTRkb7lobNUStXsB0jIXIAMSsQnWlsV+wULF4Avk9fLq2r8a5HSE35Q3eO2XP1A1wQkZSgETvDtKdQAAAABJRU5ErkJggg==';
                }

                $async = false;
                $ip_pool = 'Main Pool';

                $v = var_export( $mail, true);
                file_put_contents('phplog.txt', 'gesendet: ' . $v, FILE_APPEND);

                $result = $mandrill->messages->send($mail, $async, $ip_pool, $send_at);
    }

下面的行看起来很可疑。如果您在此处查看https://mandrillapp.com/api/docs/messages.html。您可以清楚地看到attachments是一个多维数组。

 //just some sample data for testing
        foreach ($message['attachment'] as $attachment) 
            {
                $mail['attachments']['name'] ='sample.png';
                $mail['attachments']['type'] ='image/png';
                $mail['attachments']['content'] ='iVBORw0KGgoAAAANSUhEUgAAABwAAAASCAMAAAB/2U7WAAAABlBMVEUAAAD///+l2Z/dAAAASUlEQVR4XqWQUQoAIAxC2/0vXZDrEX4IJTRkb7lobNUStXsB0jIXIAMSsQnWlsV+wULF4Avk9fLq2r8a5HSE35Q3eO2XP1A1wQkZSgETvDtKdQAAAABJRU5ErkJggg==';
            }

至少应该如下，但您仍然不能在代码中使用$attachment。但正确的用法如下。

    foreach ($message['attachment'] as $key => $attachment) 
        {
            $mail['attachments'][$key]['name'] ='sample.png';
            $mail['attachments'][$key]['type'] ='image/png';
            $mail['attachments'][$key]['content'] ='iVBORw0KGgoAAAANSUhEUgAAABwAAAASCAMAAAB/2U7WAAAABlBMVEUAAAD///+l2Z/dAAAASUlEQVR4XqWQUQoAIAxC2/0vXZDrEX4IJTRkb7lobNUStXsB0jIXIAMSsQnWlsV+wULF4Avk9fLq2r8a5HSE35Q3eO2XP1A1wQkZSgETvDtKdQAAAABJRU5ErkJggg==';
        }

如果您想以更清晰的方式尝试，请使用以下内容：

$attachment = [];
$attachment['name'] ='sample.png';
$attachment['type'] ='image/png';
$attachment['content'] ='iVBORw0KGgoAAAANSUhEUgAAABwAAAASCAMAAAB/2U7WAAAABlBMVEUAAAD///+l2Z/dAAAASUlEQVR4XqWQUQoAIAxC2/0vXZDrEX4IJTRkb7lobNUStXsB0jIXIAMSsQnWlsV+wULF4Avk9fLq2r8a5HSE35Q3eO2XP1A1wQkZSgETvDtKdQAAAABJRU5ErkJggg==';




$mail['attachments'][] = $attachment;

根据评论更新：

事情看起来很好，只需将if语句if ($message['attachments'])更改为if (is_array($message['attachments']) && count($message['attachments']) > 1)，然后将if语句$message['attachments'] = array_values($message['attachments']);

更改为

如下所示循环。只需注意$attachment我添加到语义键，你可以根据自己的需要进行更改。我不知道你获取文件，静态或文件上传的来源在哪里。我作为一个例子添加了。

    foreach ($message['attachment'] as $key => $attachment) 
        {
            $mail['attachments'][$key]['name'] =$attachment['fileName'];
            $mail['attachments'][$key]['type'] =$attachment['mimeType'];
            $mail['attachments'][$key]['content'] = chunk_split(base64_encode(file_get_contents($attachment['filePath']))); ;
        }

使用foreach循环添加mandrill电子邮件附件
