我使用下面的函数在 Drupal 模块中发送带有附件的电子邮件。它可以正常发送docx
或doc
记录文档,但是当它通过电子邮件发送 PDF 时,PDF 文件与原始文件大小不同,并且无法打开文档。我不知道为什么会这样。有人可以帮我吗?谢谢。
<?php
$file = "http://website.com/files/211546865_file.pdf";
function mail_attachment($to, $subject, $message, $from, $file) {
$filename = basename($file);
$file_size = filesize($file);
$content = chunk_split(base64_encode(file_get_contents($file)));
$uid = md5(uniqid(time()));
$from = str_replace(array("\r", "\n"), '', $from); // to prevent email injection
$header = "From: ".$from."\r\n"
."MIME-Version: 1.0\r\n"
."Content-Type: multipart/mixed; boundary=\"".$uid."\"\r\n\r\n"
."This is a multi-part message in MIME format.\r\n"
."--".$uid."\r\n"
."Content-type:text/html; charset=ISO-8859-1\r\n"
."Content-Transfer-Encoding: 7bit\r\n\r\n"
.$message."\r\n\r\n"
."--".$uid."\r\n"
."Content-Type: application/octet-stream; name=\"".$filename."\"\r\n"
."Content-Transfer-Encoding: base64\r\n"
."Content-Disposition: attachment; filename=\"".$filename."\"\r\n\r\n"
.$content."\r\n\r\n"
."--".$uid."--";
return mail($to, $subject, "", $header);
}
?>
