Signature and Push Button Fields
This demo shows you how to access signature fields and push button fields.
Both field types are read-only implementations. Technically it is implemented to allow the component access to a field apperance and to flatten it.
PHP
<?php
// load and register the autoload function
require_once __DIR__ . '/../../../../../bootstrap.php';
$document = \SetaPDF_Core_Document::loadByFilename(
$assetsDirectory . '/pdfs/etown/Order-Form.pdf',
new \SetaPDF_Core_Writer_Http('flatten.pdf', true)
);
$formFiller = new \SetaPDF_FormFiller($document);
$fields = $formFiller->getFields();
$signature = $fields->get('Signature');
// that's how you can check for a signature field (just for demonstration here)
if ($signature instanceof \SetaPDF_FormFiller_Field_Signature) {
// this makes nearly nothing in this example, because the field is not filled
$signature->flatten();
}
$sendButton = $fields->get('Send');
// that's how you can check for a push button field (just for demonstration here)
if ($sendButton instanceof \SetaPDF_FormFiller_Field_PushButton) {
$sendButton->flatten();
}
$document->save()->finish();
