提交PDF填好的表格到PHP脚本，然后电子邮件PDF作为附件

Question

我有这样的脚本，它被张贴了一段时间后，它的工作原理，但... 在Safari中找到工作（经过浏览器）不是问题。 FireFox & Opera强制您打开Acrobat Reader。当您从Acrobat Reader提交时（站在一旁），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。电子邮件附件工作正常。 打开Chrome浏览器内提交pdf但停留在pdf页面上不会重定向。从Chrome发送的附件出现在电子邮件中，但它是空的，pdf文件未打开。 我的问题是：什么是Acrobat Reader等待接收？和Chrome发生了什么？

下面是代码

$fileatt = date("d-m-Y-His") . ".pdf"; // Creates unique PDF name from the date 
copy('php://input',"pdfs/".$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软件正在等待数据...任何数据。回应一些确认收到表格的东西。 Chrome正在发送FDF，而不是PDF。我不认为附件实际上是空的，但它必须能够打开FDF中提到的PDF。
