About JCR/PHPCR


Data in a CMS is mostly unstructured

RDBMS are not a good fit, hurray for NoSQL

like fitting a square into a circle

CMS often organize content as a tree/graph

Most NoSQL not a good fit, hurray for Graph DBs

content graph

CMS should be able to store content versions

multiple versions

Magnolia and PHPCR: Scenarios


Installation

Code along if you are watching the recorded session

Prerequisites

Setup Magnolia

Magnolia configuration window

Setup the PHP project

curl -s http://getcomposer.org/installer | php --
./composer.phar init
./composer.phar require jackalope/jackalope-jackrabbit
./composer.phar install

More information at http://jackalope.github.com/

PHPCR code examples

Connecting via PHPCR

// file test.php
require_once(__DIR__ . 'vendor/autoload.php');

$parameters = array(
  'jackalope.jackrabbit_uri'
    => 'http://localhost:8080/magnoliaAuthor/.davex/'
);
$repository = Jackalope\RepositoryFactoryJackrabbit::
  getRepository($parameters);

$creds = new \PHPCR\SimpleCredentials(
  'superuser','superuser');
$website = $repository->login($creds, 'website');

Reading a value

$path = '/demo-project/about/history';
$node = $website->getNode($path);
$title = $node->getPropertyValue('title');
echo "$title\n";
            
php test.php
$ History

Read binary data

// init code as before
$repository = Jackalope\RepositoryFactoryJackrabbit::
  getRepository($parameters);
$dms = $repository->login($creds, 'dms');

$path = '/demo-project/downloads/Magnolia_Flyer_4-0';
$node = $dms->getNode($path);
$properties = $node->getNode('document')
  ->getPropertiesValues();
echo "Found document, mime-type: " .
  $properties['jcr:mimeType'] . "\n";
$filename = $properties['fileName'] . '.' .
  $properties['extension'];
file_put_contents($filename, $properties['jcr:data']);
echo "Saved to $filename\n";

Saves the file to the current directory

Updating and creating properties

$path = '/demo-project/about/history';
$node = $website->getNode($path);

// update existing property
$node->setProperty('title', 'Updated Company History');

// create a new property
$node->setProperty('foo', 'bar');

// always need to save when writing to commit changes
$website->save();

Creating a new node

// add a folder node to the repository
$node = $dms->getNode('/demo-docs/internet');
$name = 'test-folder';
$type = 'mgnl:content';
$folderNode = $node->addNode($name, $type);
$folderNode->setProperty ("title", "Test Folder");
$folderNode->setProperty ("type", "folder");

// save changes
$dms->save();

Magnolia browser

Tree Traversal API

$path = '/demo-project/about/subsection-articles';
$node = $session->getNode($path);

foreach ($node->getNodes() as $child) {
    if ($child->hasProperty('abstract')) {
        $abstract =
          $child->getPropertyValue('abstract');
        echo $child->getPath() . ": $abstract\n";
    }
}

Search via SQL2 API

$qm = $website->getWorkspace()->getQueryManager();

$sql = "SELECT *
        FROM [mgnl:page]
        WHERE ISDESCENDANTNODE('/demoproject/about')";

$query = $qm->createQuery($sql, 'JCR-SQL2');
$queryResult = $query->execute();

foreach ($queryResult->getNodes() as $node) {
    if ($node->hasProperty('title')) {
        $title = $node->getPropertyValue('title');
        echo $node->getPath . ": $title\n";
    }
}

Conclusions

Not all data fits well in PHPCR/JCR

Door swings both ways, so remember

like fitting a square into a circle
