将PDF填写表格提交给PHP脚本，然后通过电子邮件将PDF作为附件发送

Question

我有这个脚本，它发布了一段时间，并且可以运行，但是...在Safari上可以找到（通过浏览器）问题。 FireFox和Opera会强制您打开Acrobat Reader。 当您从Acrobat Reader（站着）提交时，PHP脚本提交会发送带有附件的电子邮件，但Acrobat Reader会挂起“正在接收数据...”，然后超时。 带有附件的电子邮件可以正常工作。 Chrome在浏览器中打开时提交pdf但停留在pdf页面上不会重定向。 Chrome发送的附件包含在电子邮件中，但为空，pdf文件无法打开。 我的问题是：Acrobat Reader正在等待接收什么？ 以及Chrome发生了什么？

这是代码

$fileatt = date("d-m-Y-His") . ".pdf";  // Creates unique PDF name from the date 
copy('php://input',"pdfs/".$fileatt); // Copies the pdf form data to a folder named pdfs 
$fileatt = "pdfs/".$fileatt; // Path to the file gives the pdfs folder plus the unique       file name we just assigned
$fileatt_type = "application/pdf"; // File Type 
$fileatt_name = "Application Form_".$fileatt.".pdf"; // Filename that will be used for the   file as the attachment when it is sent

$email_from = "mywebsite"; // Who the email is from 
$email_subject = "Completed online Applications"; // The Subject of the email 
$email_message = "Please find a recent online application attached.
";
$email_message .= "Any problems please email me...
"; // Message that the email has in it 

$email_to = "youremail@yourserver.com"; // Who the email is to 

$headers = "From: ".$email_from;

//no need to change anything else under this point

$file = fopen($fileatt,'rb'); 
$data = fread($file,filesize($fileatt)); 
fclose($file); 

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

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

$email_message .= "This is a multi-part message in MIME format.\n\n" . 
"--{$mime_boundary}\n" . 
"Content-Type:text/html; charset=\"iso-8859-1\"\n" . 
"Content-Transfer-Encoding: 7bit\n\n" . 
$email_message .= "\n\n"; 

$data = chunk_split(base64_encode($data)); 

$email_message .= "--{$mime_boundary}\n" . 
"Content-Type: {$fileatt_type};\n" . 
" name=\"{$fileatt_name}\"\n" . 
//"Content-Disposition: attachment;\n" . 
//" filename=\"{$fileatt_name}\"\n" . 
"Content-Transfer-Encoding: base64\n\n" . 
$data .= "\n\n" . 
"--{$mime_boundary}--\n"; 

$ok = @mail($email_to, $email_subject, $email_message, $headers); 

if($ok) { 
  unlink($fileatt); //NOW WE DELETE THE FILE FROM THE FOLDER pdfs 
  Header("Location: nextpage.php"); //where do we go once the form has been submitted.

} else { 
  die("Sorry but the email could not be sent. Please go back and try again!"); 
}

Acrobat Reader正在等待数据...任何数据。 回显确认已收到表格的内容。 Chrome正在发送FDF，而不是PDF。 我认为附件实际上不会为空，但是必须能够打开FDF中引用的PDF。
