PDF Portfolio With Dynamic Files & Metadata
This demo shows you how to add dynamic created files to a PDF portfolio and how to define things like a description, file specifc metadata or a mime-type individually.
Note: The viewer application needs to support PDF packages. Otherwise the files will be simple attachments.
PHP
<?php
// load and register the autoload function
require_once __DIR__ . '/../../../../../bootstrap.php';
// create a document as the cover sheet
$writer = new \SetaPDF_Core_Writer_Http('dynamic-portfolio.pdf');
$document = new \SetaPDF_Core_Document($writer);
$document->getCatalog()->getPages()->create(\SetaPDF_Core_PageFormats::A4);
// we leave it empty for demonstration purpose...
// create a collection instance
$collection = new \SetaPDF_Merger_Collection($document);
// add a dynamically created text file
$textFile = 'A simple text content';
$collection->addFile(
new \SetaPDF_Core_Reader_String($textFile),
'text-file.txt',
'The description of the text file.',
[
// an optional check sum
\SetaPDF_Core_EmbeddedFileStream::PARAM_CHECK_SUM => md5($textFile, true),
// modification and creation date are default columns and set automatically
// to the current date time. If you want to define them manually:
\SetaPDF_Core_EmbeddedFileStream::PARAM_MODIFICATION_DATE => new DateTime('yesterday'),
\SetaPDF_Core_EmbeddedFileStream::PARAM_CREATION_DATE => new DateTime('-1 week')
],
'text/plain'
);
// add another dynamically created text file
$textFile = 'Another simple text content';
$name = $collection->addFile(
new \SetaPDF_Core_Reader_String($textFile),
'another-text-file.txt',
'The description of the other text file.',
[],
'text/plain'
);
// get the file specification by its name
$fileSpecification = $collection->getFile($name);
// get the embedded file stream and add additional parameters
$fileSpecification->getEmbeddedFileStream()->setParams([
\SetaPDF_Core_EmbeddedFileStream::PARAM_CHECK_SUM => md5($textFile, true),
\SetaPDF_Core_EmbeddedFileStream::PARAM_MODIFICATION_DATE => new DateTime('yesterday'),
\SetaPDF_Core_EmbeddedFileStream::PARAM_CREATION_DATE => new DateTime('last Wednesday')
], false);
// save and finish
$document->save()->finish();
