PHP: Fill PDF form - php

Question

I have a PDF document which contains form with couple of form fields. I need to do following:
Load that PDF document
Itearate through all the form fields of that document and fill it up with the data
Download filled flatten document
I have seen few of libraries, but most of them are relying on the PDFtk. But the case is that I don't have the possibility to install PDFtk on the server.
Is there any library which allows such action and is "pure" php so I don't have to install anything on server?

Answer 1

You can use the SetaPDF-FormFiller component for this task (not free! And I'm related to the company behind). Let $data be your array of data, a simple usage example would be:
// Load that PDF document
$document = SetaPDF_Core_Document::loadByFilename('path/to.pdf');
$formFiller = new SetaPDF_FormFiller($document);
// Itearate through all the form fields of that document and fill it up with the data
$fields = $formFiller->getFields();
foreach ($fields->getNames() as $fieldName) {
$field = $fields->get($fieldName);
$field->setValue($data[$fieldName]);
}
// flatten document
$fields->flatten();
// Download filled flatten document
$writer = new SetaPDF_Core_Writer_Http('result.pdf');
$document->setWriter($writer);
$document->save()->finish();
It is all done in pure PHP and requires only common PHP extensions to be enabled (see system requirements).
