无法从客户端PC（上传）附加文件

Question

我在example.com/contact-us.php上有一个表格，看起来像这样（简化）：

<form method="post" action="process.php" enctype="multipart/form-data">
  <input type="file" name="uploaded_file" id="uploaded_file" />
  <input type="hidden" name="MAX_FILE_SIZE" value="10000000" />
</form>

在我的process.php文件中，我使用以下代码利用PHPMailer()发送电子邮件：

require("phpmailer.php");

$mail = new PHPMailer();

$mail->From     = me@example.com;
$mail->FromName = My name;
$mail->AddAddress(me@example.com,"John Doe");

$mail->WordWrap = 50;
$mail->IsHTML(true);

$mail->Subject  =  "Contact Form Submitted";
$mail->Body     =  "This is the body of the message.";

电子邮件正确发送正文，但没有附件uploaded_file。

我的问题

我需要将表单中的文件uploaded_file附加到电子邮件中，然后发送。在process.php脚本通过电子邮件发送文件后，我不关心保存文件。

我知道我需要在某处添加AddAttachment();（我假设在Body行下）才能发送附件。但...

我在process.php文件的顶部放置了什么来提取文件uploaded_file？就像使用$_FILES['uploaded_file']从contact-us.php页面中提取文件一样？
AddAttachment();内部要附加的文件和电子邮件一起发送的内容以及此代码需要去哪里？

请帮助并提供代码！谢谢！

Answer 1

尝试：

if (isset($_FILES['uploaded_file']) &&
    $_FILES['uploaded_file']['error'] == UPLOAD_ERR_OK) {
    $mail->AddAttachment($_FILES['uploaded_file']['tmp_name'],
                         $_FILES['uploaded_file']['name']);
}

也可以找到基本示例here。

AddAttachment的功能定义是：

public function AddAttachment($path,
                              $name = '',
                              $encoding = 'base64',
                              $type = 'application/octet-stream')

Answer 2

无法从客户端PC（上传）附加文件

在HTML表单中，我没有添加以下行，因此没有附件：

ENCTYPE = “多部分/格式数据”

在表格中添加上述行（如下所示）后，附件变得完美。

<form id="form1" name="form1" method="post" action="form_phpm_mailer.php"  enctype="multipart/form-data">

Answer 3

此代码可以帮助我发送附件......

$mail->AddAttachment($_FILES['file']['tmp_name'], $_FILES['file']['name']);

用上面的代码替换你的AddAttachment（...）代码

Answer 4

你使用$_FILES['uploaded_file']['tmp_name']，这是PHP存储上传文件的路径（它是一个临时文件，当脚本结束时由PHP自动删除，除非你已将其移动/复制到别处）。 / p>

假设您的客户端表单和服务器端上载设置正确，您无需“拉入”上传。它只是在tmp_name路径中神奇地可用。

请注意，您必须验证上传确实成功，例如

if ($_FILES['uploaded_file']['error'] === UPLOAD_ERR_OK) {
    ... attach file to email ...
}

否则，您可能会尝试使用已损坏/部分/不存在的文件进行附件。

使用此代码通过phpmailer中的html表单发送带有上传文件选项的附件

 <form method="post" action="" enctype="multipart/form-data">


                    <input type="text" name="name" placeholder="Your Name *">
                    <input type="email" name="email" placeholder="Email *">
                    <textarea name="msg" placeholder="Your Message"></textarea>


                    <input type="hidden" name="MAX_FILE_SIZE" value="30000" />
                    <input type="file" name="userfile"  />


                <input name="contact" type="submit" value="Submit Enquiry" />
   </form>


    <?php




        if(isset($_POST["contact"]))
        {

            /////File Upload

            // In PHP versions earlier than 4.1.0, $HTTP_POST_FILES should be used instead
            // of $_FILES.

            $uploaddir = 'uploads/';
            $uploadfile = $uploaddir . basename($_FILES['userfile']['name']);

            echo '<pre>';
            if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
                echo "File is valid, and was successfully uploaded.\n";
            } else {
                echo "Possible invalid file upload !\n";
            }

            echo 'Here is some more debugging info:';
            print_r($_FILES);

            print "</pre>";


            ////// Email


            require_once("class.phpmailer.php");
            require_once("class.smtp.php");



            $mail_body = array($_POST['name'], $_POST['email'] , $_POST['msg']);
            $new_body = "Name: " . $mail_body[0] . ", Email " . $mail_body[1] . " Description: " . $mail_body[2];



            $d=strtotime("today"); 

            $subj = 'New enquiry '. date("Y-m-d h:i:sa", $d);

            $mail = new PHPMailer(); // create a new object


            //$mail->IsSMTP(); // enable SMTP
            $mail->SMTPDebug = 1; // debugging: 1 = errors and messages, 2 = messages only ,false = Disable 
            $mail->Host = "mail.yourhost.com";
            $mail->Port = '465';
            $mail->SMTPAuth = true; // enable 
            $mail->SMTPSecure = true;
            $mail->IsHTML(true);
            $mail->Username = "admin@domain.net"; //from@domainname.com
            $mail->Password = "password";
            $mail->SetFrom("admin@domain.net", "Your Website Name");
            $mail->Subject = $subj;
            $mail->Body    = $new_body;

            $mail->AddAttachment($uploadfile);

            $mail->AltBody = 'Upload';
            $mail->AddAddress("recipient@domain.com");
             if(!$mail->Send())
                {
                echo "Mailer Error: " . $mail->ErrorInfo;
                }
                else
                {

                echo '<p>       Success              </p> ';

                }

        }

嘿伙计们，下面的代码对我来说非常合适。只需将setFrom和addAddress替换为您的首选项即可。

<?php
/**
 * PHPMailer simple file upload and send example.
 */
//Import the PHPMailer class into the global namespace
use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\Exception;
$msg = '';
if (array_key_exists('userfile', $_FILES)) {
    // First handle the upload
    // Don't trust provided filename - same goes for MIME types
    // See http://php.net/manual/en/features.file-upload.php#114004 for more thorough upload validation
    $uploadfile = tempnam(sys_get_temp_dir(), hash('sha256', $_FILES['userfile']['name']));
    if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) 
    {
        // Upload handled successfully
        // Now create a message

        require 'vendor/autoload.php';
        $mail = new PHPMailer;
        $mail->setFrom('info@example.com', 'CV from Web site');
        $mail->addAddress('blabla@gmail.com', 'CV');
        $mail->Subject = 'PHPMailer file sender';
        $mail->Body = 'My message body';

        $filename = $_FILES["userfile"]["name"]; // add this line of code to auto pick the file name
        //$mail->addAttachment($uploadfile, 'My uploaded file'); use the one below instead

        $mail->addAttachment($uploadfile, $filename);
        if (!$mail->send()) 
        {
            $msg .= "Mailer Error: " . $mail->ErrorInfo;
        } 
        else 
        {
            $msg .= "Message sent!";
        }
    } 
        else 
        {
            $msg .= 'Failed to move file to ' . $uploadfile;
        }
}
?>

<?php } else {
    echo $msg;
} ?>
</body>
</html>

Answer 7

在我自己的情况下，我在表单上使用serialize()，因此文件没有被发送到php。如果您使用的是jquery，请使用FormData()。例如

<form id='form'>
<input type='file' name='file' />
<input type='submit' />
</form>

使用jquery，

$('#form').submit(function (e) {
e.preventDefault();
var formData = new FormData(this); // grab all form contents including files
//you can then use formData and pass to ajax

});

Answer 8

这将完美地工作

    <form method='post' enctype="multipart/form-data">
    <input type='file' name='uploaded_file' id='uploaded_file' multiple='multiple' />
    <input type='submit' name='upload'/> 
    </form>

    <?php
           if(isset($_POST['upload']))
        {
             if (isset($_FILES['uploaded_file']) && $_FILES['uploaded_file']['error'] == UPLOAD_ERR_OK)
                {
                     if (array_key_exists('uploaded_file', $_FILES))
                        { 
                            $mail->Subject = "My Subject";
                            $mail->Body = 'This is the body';
                            $uploadfile = tempnam(sys_get_temp_dir(), sha1($_FILES['uploaded_file']['name']));
                        if (move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $uploadfile))
                             $mail->addAttachment($uploadfile,$_FILES['uploaded_file']['name']); 
                            $mail->send();
                            echo 'Message has been sent';
                        }       
                else
                    echo "The file is not uploaded. please try again.";
                }
                else
                    echo "The file is not uploaded. please try again";
        }
    ?>
