使用PHP将FDF数据合并为PDF

目前，我拥有在服务器上创建.xfdf文件的代码，以及用于填充的PDF文件。我不断得到我想要用仍然空白的表单字段填充的pdf。Employee Packet.pdf是用Application.xfdf填充的pdf。两者都位于我的Web服务器上的/results目录中

我知道我的代码的开头部分是不完整的，我只让它在提交前检查“名字”字段。我想完成这项工作，但我主要关心的是在web服务器上填写指定的PDF，并将完成的产品通过电子邮件发送给用户

我从这里抓取了“pass-thru”代码，但我认为它是用于第三方应用程序功能的。任何帮助都会很好，提前谢谢

<?php 
    // check that a form was submitted 
    if(isset($_POST) && is_array($_POST) && count($_POST)){ 
        // we will use this array to pass to the createFDF function 
        $data=array(); 


        if(isset($_POST['FIRST_NAME'])){ 
            // the name field was submitted 
            $pat='`[^a-z0-9\s]+$`i'; 
            if(empty($_POST['FIRST_NAME']) || preg_match($pat,$_POST['FIRST_NAME'])){ 
                // no value was submitted or something other than a 
                // number, letter or space was included 
                die('Invalid input for First Name field.'); 
            }else{ 
                // if this passed our tests, this is safe 
                $data['FIRST_NAME']=$_POST['FIRST_NAME']; 
            } 



            if(!isset($_POST['FIRST_NAME'])){ 
                // Why this? What if someone is spoofing form submissions 
                // to see how your script works? Only allow the script to 
                // continue with expected data, don't be lazy and insecure ;) 
                die('You did not submit the correct form.'); 
            } 

            // Check your data for ALL FIELDS that you expect, ignore ones you 
            // don't care about. This is just an example to illustrate, so I 
            // won't check anymore, but I will add them blindly (you don't want 
            // to do this in a production environment).
