使用php将文件附加到电子邮件

标签: php email file attachment

我的表单上有一个输入,允许用户浏览到文件位置。他们的想法是,他们可以将简历附加到他们准备提交的应用程序中。

<label class="description" for="element_5">Upload a File </label>
        <div>
            <input id="element_5" name="element_5" class="element file" type="file"/> 

对于我的文字字段和下拉菜单,我一直在使用以下内容:

$experince = $_POST["experince"];

但是我不希望路径字符串我想要实际的文件。如何获取文件本身以及如何将其附加到电子邮件中?

此外,是否有一种简单的方法可以将附件限制为.DOC / .PDF?

我最近做了类似的事情。这不是微不足道的。

您的电子邮件必须是多部分Mime消息。您将读入您的文件,对其进行编码(使用base64),然后将其放在正确位置的电子邮件消息字符串中。

这看起来像一个体面的教程(我希望我以前找到过): http://www.texelate.co.uk/blog/send-email-attachment-with-php/

但请注意,该教程有一些逃避问题:

$message . "“nn";

应该是:

$message . "\n\n";

您还可以查看Mail_Mime PEAR包以获取帮助: http://pear.php.net/package/Mail_Mime

以下是我发送带附件的邮件的方法。一些代码是我的,其中一些代码来自http://php.net/manual/en/function.mail.php。此代码已经过试用和测试,因此应该可以使用。另请参阅sendmail是否已安装。如果在linux上ubuntu系统尝试sudo apt-get install sendmail来安装它。 关于此代码的最佳部分是它适用于多个文件上传。

文件名:index.php

    <?php
    if( $_POST || $_FILES )
    {
            // email fields: to, from, subject, and so on
            // Here 
            $from = "someone@somewhere.com";
            $to = "someone_else@somewhere_else.com";
            $subject = "Mail with Attachment";
            $message = "This is the message body and to it I will append the attachments.";
            $headers = "From: $from";

            // boundary
            $semi_rand = md5(time());
            $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";

            // headers for attachment
            $headers .= "\nMIME-Version: 1.0\n" . "Content-Type: multipart/mixed;\n" . " boundary=\"{$mime_boundary}\"";

            // multipart boundary
            $message = "--{$mime_boundary}\n" . "Content-Type: text/plain; charset=\"iso-8859-1\"\n"."Content-Transfer-Encoding: 7bit\n\n" . $message . "\n\n";
            fixFilesArray($_FILES['attachment']);
            foreach ($_FILES['attachment'] as $position => $file) 
            {
                    // should output array with indices name, type, tmp_name, error, size
                    $message .= "--{$mime_boundary}\n";
                    $fp     = @fopen($file['tmp_name'],"rb");
                    $data   = @fread($fp,filesize($file['tmp_name']));
                    @fclose($fp);
                $data = chunk_split(base64_encode($data));
                $message .= "Content-Type: application/octet-stream; name=\"".$file['name']."\"\n"."Content-Description: ".$file['name']."\n" ."Content-Disposition: attachment;\n" . " filename=\"".$file['name']."\";size=".$file['size'].";\n"."Content-Transfer-Encoding: base64\n\n" . $data . "\n\n";
            }
            $message .= "--{$mime_boundary}--";
            $returnpath = "-f" . $from;
            $ok = @mail($to, $subject, $message, $headers, $returnpath);
            if($ok){ return 1; } else { return 0; }
    }
    //This function will correct file array from $_FILES[[file][position]] to $_FILES[[position][file]] .. Very important

    function fixFilesArray(&$files)
    {
            $names = array( 'name' => 1, 'type' => 1, 'tmp_name' => 1, 'error' => 1, 'size' => 1);

            foreach ($files as $key => $part) {
                    // only deal with valid keys and multiple files
                    $key = (string) $key;
                    if (isset($names[$key]) && is_array($part)) {
                            foreach ($part as $position => $value) {
                                    $files[$position][$key] = $value;
                            }
                            // remove old key reference
                            unset($files[$key]);
                    }
            }
    }
    ?>
    <html>
        <body>
            <form method="POST" action="index.php" enctype="multipart/form-data">
                <input type="file" name="attachment[]"><br/>
                <input type="submit">
            </form>
        </body>
    </html>

顺便说一下,我想为使用sendmail道歉,因为它有点慢。我会尝试发布一个更好的解决方案。

这是我迄今为止所做的,但它不起作用

<input id="resumeup" name="resumeup"  type="file"/> 

<?php $_FILES = $_POST["resumeup"];

            if ((($_FILES["file"]["type"] == "image/gif")
            || ($_FILES["file"]["type"] == "image/jpeg")
            || ($_FILES["file"]["type"] == "image/pjpeg"))
            && ($_FILES["file"]["size"] < 20000))
            {
                if ($_FILES["file"]["error"] > 0)
                {
                    echo "Error: " . $_FILES["file"]["error"] . "<br />";
                }
                else
                {
                    echo "Upload: " . $_FILES["file"]["name"] . "<br />";
                    echo "Type: " . $_FILES["file"]["type"] . "<br />";
                    echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
                    echo "Stored in: " . $_FILES["file"]["tmp_name"];
                }
            } ?>
