title: manipulate pdf form with fill-able form fields and keep them fillable by user?
body: <p>I got a form with fill-able form fields made by Acrobat, it is rather complex.
  Via PHP I want to "simply" attach another page, add a barcode to the form page and add meta info.</p>
  
  <p>Currently I do not manage to retain the fields fill-able or tcpdf/fpdi simply cannot read the compression of the pdf. I tried a couple of different pdf version but don't succeed so far.</p>
  
  <p>I tried pdflib but work now with tcpdf and fpdi, however there seems no way to make it happen.
  I can attach pdf files and use templates, just not in any format that has or retains fill-able fields.</p>
  
  <ol>
  <li>Is tcpdf/fpdi able to do this at all?</li>
  <li>Do you know of any other solution to achieve this? (PHP/linux based)</li>
  </ol>
