Swift Mailer附件

Question

我正在用PHP动态创建一个CSV，然后我需要将这个CSV文件附加到Swift Mailer消息中。我尝试在创建的文件上使用file_get_content，在创建的文件上使用chunk_split(base64_encode(file_get_contents())，并在将文件写入磁盘之前附加该文件。在没有写入磁盘的情况下，我在CSV中获得了资源#183，通过使用file_get_content附加它，我在CSV文件的每一行中只得到了一个字符串，有人知道我做错了什么吗？

if(!file_exists(_PS_ORDERS_DIR_.$orderDate.'/'.$file_name.'.csv'))
 {
  if($file = fopen (_PS_ORDERS_DIR_.$orderDate.'/'.$file_name.'.csv', 'x+'))
   {
   foreach ($list as $fields)
    {
     fputcsv($file, $fields);
    }



    $attachment['mime'] = 'application/vnd.ms-excel';
    $attachment['content'] = file_get_contents($file);
    $attachment['name'] = $order.'order';
  EDIT            
 Mail::Send(1, 'order_conf', 'Order CSV Attachment', $success, 'test@email.com', Address, NULL, NULL, $attachment); // attach and send
      }
      }

Answer 1

将文件附加到快速邮件程序中：

$swift =& new Swift(new Swift_Connection_SMTP(MAIL_SMTP_URL, MAIL_SMTP_PORT));
$message =& new Swift_Message($subject);
$recpients =& new Swift_RecipientList();
$sender =& new Swift_Address('info@example.com', 'example.com');
$recpients->addTo('info@example.com', 'www.example.com');

$message->attach(new Swift_Message_Part('this is my body'));
$message->attach(new Swift_Message_Attachment($binarycontents, $fileTitle, $mimeType));
$swift->send($message, $recpients, $sender);

在您的示例中，附加内容为：

$message->attach(new Swift_Message_Attachment(file_get_contents($file), $order.'order.csv', 'application/vnd.ms-excel'));

当然，只是举个例子:)

Answer 2

//to set headers of csv file(first row)
$content = "user_id,first_name,last_name,phone,gender,pan_number\r\n";

//this can be dynamic data from database or from anywhere can loop this for multiple rows
$content .= "1,test_fn,test_ln,8888999900,M,ASDD3333\r\n";

//include swiftmailer library in order to run the below code
Yii::$app->mailer->compose()
->setFrom(array('test@test.com'=>'test'))
->setTo('testto@testto.com')
->setSubject('your subject' )
->setHtmlBody('<table><tr><td>your email body message here</td></tr>       </table>')
->attachContent($content, ['fileName' => 'user.csv', 'contentType' => 'application/vnd.ms-excel'])->send();
