如何在php中填写PDF表单

Question

我有很多PDF表单,我需要在php中填写我已有的数据.

这里只是一个示例PDF表单 ,我想用php填写此表单.我在DB中已有的数据.我只想填写此表并保存.

我正在使用PHP Zend Framework.

我想要的只是当我从我的网站下载这些表格时,它会预先填写pdf表格中的所有字段以及我已有的信息.

请帮我.

Answer 1

调用pdftk是实现这一目标的好方法.我假设您知道如何执行外部程序并将其排除在外.

首先,从PDF 创建FDF文件.

pdftk form.pdf generate_fdf output data.fdf

您现在可以将其用作模板.您提供的示例如下所示:

%FDF-1.2
%<E2><E3><CF><D3>
1 0 obj 
<<
/FDF 
<<
/Fields [
<<
/V ()
/T (Date)
>> 
<<
/V /
/T (CheckBox2)
>> 
<<
/V /
/T (CheckBox3)
>> 
<<
/V /
/T (CheckBox4)
>> 
<<
/V /
/T (CheckBox5)
>> 
<<
/V ()
/T (Your_Last_Name)
>> 
<<
/V ()
/T (Your_First_Name)
>> 
<<
/V /
/T (CheckBox1)
>>]
>>
>>
endobj 
trailer

<<
/Root 1 0 R
>>
%%EOF

字段是以字母开头的行/V ().在这些字段中输入所需的值.例如:

%FDF-1.2
%<E2><E3><CF><D3>
1 0 obj 
<<
/FDF 
<<
/Fields [
<<
/V (February 4, 2012)
/T (Date)
...

最后,将FDF与PDF合并.执行命令:

pdftk form.pdf fill_form data.fdf output form_with_data.pdf

如果您不需要保留FDF并生成PDF文件,则只需通过stdin和stdout管道数据,而不是使用临时文件.

我发现了这个,它对我有用.这是Zend填补FDF表格字段的非正式补丁.网站与讨论和补丁

没有安装,没有外部程序,没有坐标

使用:

$pdf = Zend_Pdf::load('input-file-containing-form.pdf');
$pdf->setTextField('name', 'Someone');
$pdf->setTextField('address', '1 Main Street');
$pdf->setTextField('city', 'Cyberspace');
$pdf->save('outputfile.pdf');

如果页面不再存在,这里是PDF.php的补丁(如果有人有问题 - 给我写privete消息):

我发现 fpdf 库在互联网上寻找相同的库。

http://www.fpdf.org/en/script/script93.php

代码看起来干净、易于使用和记住，并且适用于带有表单的 pdf（可填写）。

<?php

/***************************
  Sample using a PHP array
****************************/

require('fpdm.php');

$fields = array(
    'name'    => 'My name',
    'address' => 'My address',
    'city'    => 'My city',
    'phone'   => 'My phone number'
);

$pdf = new FPDM('template.pdf');
$pdf->Load($fields, false); // second parameter: false if field values are in ISO-8859-1, true if UTF-8
$pdf->Merge();
$pdf->Output();
?>

它带有开箱即用的示例。希望能帮助到你。
