我使用http://koivi.com/fill-pdf-form-fields/中的Form to PDF脚本，并希望将PDF发送到电子邮件。幸运的是，他已经通过使用文件“process-xfdf.php”实现了这一目标。但是，我似乎无法找到如何正确使用此文件，因为我总是得到“此脚本只与我们网站上的Web表单一起使用。” - 错误消息。
我做错了什么？

<h1>Using HTML forms to fill in PDF fields with PHP and FDF</h1>
<p>Using a simple HTML form and a small PHP function, it is possible to fill in the fields of a PDF form file for viewing without having to install any PHP libraries or modules. This is accomplished by using a pre-made PDF file with all the form fields necessary and FDF files.</p>
<p>By taking values provided via a GET or POST web request from an HTML form or hyperlink, we can generate an FDF file that, when opened, will provide the values to fill the PDF form fields in the original document.</p>
<h1>Tutorial</h1>
<p>I have now posted a <a href="./tutorial.php">tutorial</a> on how to use the programming found in this article for those of you who need just a little extra help implementing this.</p>
</div>
<?php
if(isset($CREATED)){
?>
<div id="pageResults">
<h1>Your Result</h1>
<p>You can now <a href="<?php echo str_replace(dirname(__FILE__).'/','',$fdf_file) ?>">download</a> the file you just created. When downloaded, open the FDF file with your Adobe Acrobat or Acrobat Reader program to view the original PDF document with the fields filled in with the information you posted through the form below.</p>
</div>
<?php
}
?>
<div>
<h1>Creating the PDF file</h1>
<p>First, you need to have created your <a href="test.pdf">PDF form file</a>. I do this using the form tools in Adobe Acrobat. Remember to name each field in your document, you will need those names later when you create the HTML form.</p>
</div>
<div>
<h1>Creating the HTML form</h1>
<p>Next, you need to create the form fields to fill out in an HTML form. Below is an example that fits with the above PDF file. Note that the field names in your HTML form must match the field names in your PDF file.</p>
<form method="post" action="process-xfdf.php">
<table cellpadding="3" cellspacing="0" border="0">
<tr><td>Name</td><td><input type="text" name="__NAME__" value="<?php if(isset($_POST['__NAME__'])) echo $_POST['__NAME__']; ?>" /></td></tr>
<tr><td>Title</td><td><input type="text" name="__TITLE__" value="<?php if(isset($_POST['__TITLE__'])) echo $_POST['__TITLE__']; ?>" /></td></tr>
<tr><td>Email</td><td><input type="text" name="__EMAIL__" value="<?php if(isset($_POST['__EMAIL__'])) echo $_POST['__EMAIL__']; ?>" /></td></tr>
<tr><td>Address</td><td><input type="text" name="__ADDRESS__" value="<?php if(isset($_POST['__ADDRESS__'])) echo $_POST['__ADDRESS__']; ?>" /></td></tr>
<tr><td>City</td><td><input type="text" name="__CITY__" value="<?php if(isset($_POST['__CITY__'])) echo $_POST['__CITY__']; ?>" /></td></tr>
<tr><td>State</td><td><input type="text" name="__STATE__" value="<?php if(isset($_POST['__STATE__'])) echo $_POST['__STATE__']; ?>" /></td></tr>
<tr><td>Zip</td><td><input type="text" name="__ZIP__" value="<?php if(isset($_POST['__ZIP__'])) echo $_POST['__ZIP__']; ?>" /></td></tr>
<tr><td>Phone</td><td><input type="text" name="__PHONE__" value="<?php if(isset($_POST['__PHONE__'])) echo $_POST['__PHONE__']; ?>" /></td></tr>
<tr><td>Fax</td><td><input type="text" name="__FAX__" value="<?php if(isset($_POST['__FAX__'])) echo $_POST['__FAX__']; ?>" /></td></tr>
</table>
<input type="submit" />
</form>
</div>
<div>
<h1>Processing the POST request</h1>
<p>When the form is submitted, the $_POST array is passed to a function along with the location of the PDF file. The function returns the contents of an FDF file. This can them be used to write an FDF file to download an view.</p>
</div>
<div>
<h1>The code behind this</h1>
<div class="example"><?php highlight_file(dirname(__FILE__).'/createFDF.php'); ?></div>
<h2>Code for using XFDF formatted data</h2>
<div class="example"><?php highlight_file(dirname(__FILE__).'/createXFDF.php'); ?></div>
</div>
<div>
<h1>Code Download</h1>
<p>Because of the number of requests I have received for help getting this to work or copies of the code and PDF files, I have created a ZIP archive of this entire directory and am making it <a href="/fill-pdf-form-fields.zip">available for download</a> (~180K - updated 2006-09-08).</p>
<p>Inside this zip file you will also find a file named <code>process-xfdf.php</code> which contains sample code for sending results as an email attachment as well as sending the output directly to the browser.</p>
</div>
<div>
<h1>Updates</h1>
<p>Seriously, read these updates as they may have some additional information about what YOU are trying to accomplish</p>
<ul>
<li>
<p><b>2011-01-18</b> Unbelievably, I am still getting a TON of email about this article. The most often-asked question I receive is how to send the result via email attachment. For those of you that missed it, check under the "Code Download" section of the article. I added that mid 2009. I will no longer reply to emails asking for an example of how to do this since the answer is right next to where you click to download. (There are a lot of people that don't take the time to read!)</p>
<p>The next most frequent question is where to find the final PDF file. This process does not create a PDF file. It only creates FDF or XFDF files. However, there have been a few people nice enough to reply back to me with a solution after I explained that my code doesn't do it. While I have not tried it myself (as I haven't had the time or need to do so), <a href="http://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/">PDFLabs' pdftk</a> boasts "Fill PDF Forms with FDF Data or XFDF Data and/or Flatten Forms." If anyone wants to write a how-to for this process, give me a URL and I will link over to you. Alternatively, email it to me, and I will create a page to put up with this article as well.</p>
</li>
<li>
<p><b>2010-02-17</b> Minor update to the createXFDF function to allow for html entities in the values posted to the script.</p>
</li>
<li>
<p><b>2009-07-15</b> It has been a few years since I posted this and nearly as long since I have used it. However, I still get emails about this all the time. Apparently the programming is still useful for people to store the form data. I did receive an email about a month or so ago about a rogue line of code in the createXFDF function that was left over from the createFDF version of the function. Thank you AndreasDoöler for bringing this to my attention. I have now updated the function and download appropriately.</p>
</li>
<li>
<p><b>2006-09-08</b> For those of you having problems with using PDF files created from Acrobat 7 or Designer, you'll be please to hear that I have an update for you.</p>
<p>The problems were stemming from the way that the latest Acrobat, Acrobat Reader and Designer handle form data. Instead of using the previous FDF format, these programs are now defaulting to the newer XFDF file format. This is basically an XML-like file structure to define the values that would be filled into the fields.</p>
</li>
<li>
<p><b>2005-09-12</b> In the move from my last web server, I found that some of my files were corrupted, and this particular demonstrations was not working correctly. That should be all fixed up now.</p>
<p>Also, I did update the createFDF function a little as well. It turned out that Acrobat 7 was having problems importing data into the PDF form if there were spaces in the field definitions inside the FDF file. I have removed those spacer, and tested on a couple simple files. I will test on a better file with more options when I have a chance.</p>
</li>
<li>
<p>
<b>2005-04-21</b> - Thanks to Adrian James for submitting information about the FDF format of a multiple value selection field
(<code><select multiple="multiple"></code> HTML equivalent). The createFDF function has now been updated to support these fields as well.

你们中的任何人能帮助我吗？我迫切需要帮助！
答案 0 :(得分：1)
来自process-xfdf.php的来源：
if(isset($_POST['submit'])){
// [omitted]
}else{
die('This script is meant to be used in conjunction with the web forms on our website only.');
}
很明显，脚本需要通过POST从特定表单输入，并且它还希望$text_fields数组中的所有字段都存在，以便可以将它们填入PDF。
很明显，您没有尝试进行任何故障排除，也没有尝试阅读源代码并理解错误发生的原因。错误消息是该脚本中最后一行代码。
您将需要从上到下阅读整个示例脚本，因为您中有设置，条件，错误消息和其他行为了解以实现您的目标。
答案 1 :(得分：-1)
Charles，您远未找到导致错误的脚本的正确部分。该错误不是由die脚本引起的，而是由脚本的不同部分引起的。
首先，请确认您使用此表单的所有文件都在同一目录中。
由于您收到骰子消息，表示您的表单已正确设置表单操作。如果不是你就不会得到那个消息。 ：）
仔细检查您的脚本。我能够通过复制上面的代码让它工作。我只更改了我的电子邮件设置，但它确实有效。
