codeigniter 多个文件提交在电子邮件中发送

Question

如何发送电子邮件附件中的多个文件。

在视图文件中

  <input type="file" name="attachment" id="file_1" />
  <input type="file" name="attachmenttwo" id="file_2" />
  <input type="file" name="attachmentthree" id="file_3" />

在我的控制器中

 $config['upload_path'] = './uploads/';
 $config['allowed_types'] = 'gif|jpg|png|txt';
 $config['max_size'] = '100000';
 $config['overwrite'] = TRUE;
 $config['encrypt_name'] = TRUE;
 $this->load->library('upload', $config);
 $this->load->library('email');
 $this->load->library('encrypt');
 $this->upload->initialize($config);
 $this->upload->do_upload('attachment');
 $this->upload->do_upload('attachmenttwo');
 $this->upload->do_upload('attachmenthree');
 $ret = $this->upload->data();
 $rettwo = $this->upload->data();
 $retthree = $this->upload->data();
 $pathToUploadedFile = $ret['full_path'];
 $pathToUploadedFiletwo = $rettwo['full_path'];
 $pathToUploadedFilethree = $retthree['full_path'];
 $this->email->from('abc@gmail');
 $this->email->to('bcd@gmail.com');
 $this->email->subject('New query');
 $this->email->message('hi');
 $this->email->attach($pathToUploadedFile);
 $this->email->attach($pathToUploadedFiletwo);
 $this->email->attach($pathToUploadedFilethree);
 $this->email->send();

我可以在服务器中成功上传文件，但无法通过电子邮件发送附件，我在收件箱中收到了最后一个文件 3 次。

建议我如何发送收件箱中的所有文件

Answer 1

// Load uploader library

$config['upload_path'] = '/usr/local/var/www/Test/ci/uploads/';
$config['allowed_types'] = 'txt|pdf';
$config['overwrite'] = TRUE;
$config['encrypt_name'] = TRUE;

$this->load->library('upload');
$this->upload->initialize($config);

// load email library
$configmail = Array(
    'protocol' => 'smtp',
    'smtp_host' => 'ssl://smtp.googlemail.com',
    'smtp_port' => 465,
    'smtp_user' => 'abc@gmail.com', 
    'smtp_pass' => 'passwrd', 
    'mailtype' => 'html',
    'charset' => 'iso-8859-1',
    'wordwrap' => TRUE
);

$this->load->library('email', $configmail);
$this->email->set_newline("\r\n");
$this->email->from('abc@gmail.com');
$this->email->to($email);
$this->email->subject($subject);
$this->email->message($message);

foreach ($_FILES as $key => $value) {

    if (!empty($key['userfile'])) {

        if (!$this->upload->do_upload($key)) { 
          // show error or something you want
        } else { 
            // attache file in email
            $upload_data = $this->upload->data();
            $this->email->attach($upload_data['full_path']);
        }
    }
}

// finally send email
$this->email->send();

你的 html 应该是这样的

文件一

<input type="file" name="userfile[]" id="file_1" />

文件二

<input type="file" name="userfile[]" id="file_2" />

文件三

<input type="file" name="userfile[]" id="file_3" />

Answer 2

你能对这些文件进行比较吗？

$pathToUploadedFile = $ret['full_path'];
$pathToUploadedFiletwo = $rettwo['full_path'];
$pathToUploadedFilethree = $retthree['full_path'];

通过这种方式：

$pathToUploadedFile = $ret['full_path'];
$pathToUploadedFiletwo = $rettwo['full_path'];
$pathToUploadedFilethree = $retthree['full_path'];
var_dump($pathToUploadedFile);
var_dump($pathToUploadedFiletwo);
var_dump($pathToUploadedFilethree);

如果这些是相同的路径，可能是你在获取提交表单的文件时出错了。

使用此代码

首先我们需要在名称为服务器的服务器上上传数据然后我们附加文件名然后我们创建循环然后发送电子邮件

 if($this->input->post('attachment') && !empty($_FILES['userFiles']['name'])){
      $filesCount = count($_FILES['userFiles']['name']);
        for($i = 0; $i < $filesCount; $i++){
            $_FILES['userFile']['name'] = $_FILES['userFiles']['name'][$i];
            $_FILES['userFile']['type'] = $_FILES['userFiles']['type'][$i];
            $_FILES['userFile']['tmp_name'] = $_FILES['userFiles']['tmp_name'][$i];
            $_FILES['userFile']['error'] = $_FILES['userFiles']['error'][$i];
            $_FILES['userFile']['size'] = $_FILES['userFiles']['size'][$i];
            $uploadPath = './uploads/';
            $config['upload_path'] = $uploadPath;
           $config['allowed_types'] = 'gif|jpg|png|txt';

            $this->load->library('upload', $config);
            $this->upload->initialize($config);
            if($this->upload->do_upload('userFile')){
             $fileData = $this->upload->data();
             $this->load->library('email'); 
             $this->email->from('abc@gmail.com');
             $this->email->to('abc@gmail.com');
             $this->email->subject('New query');
             $this->email->message($message);
                $pathToUploadedFile = $fileData['full_path'];
                $this->email->attach($pathToUploadedFile);
            }
        }

      $this->email->send();
    }
