In this talk, we'll look at the tools and modules available for migrating content into Drupal. I'll describe the workflow I've used to prepare, transform, and import thousands of records into Drupal. I'll share strategies for cleaning up and parsing data and doing it in a reliable, repeatable manner. You'll learn how to efficiently use PHP, Feeds, and Feeds XPath Parser modules to handle almost any data source thrown your way.

  • 18. Musketeers.me 1. Parse CSV // read in our Sample CSV file // and clean up incoming data with sampleParser $csv = new readCsv(__DIR__ . '/sample.csv'); $csv->setKey('id'); $items = $csv->getArray('ProfileParser');
  • 19. 2. Clean up incoming function profileParser($item) { // skip profiles without an email if (empty($item['email'])) return false; Musketeers.me ! // create a first+last item $item['last_first'] = $item['last_name'] . ', ' . $item['first_name']; ! // cleanup & split the tags column into an array if (isset($item['tags'])) { $tags = explode(',', $item['tags']); $tags = array_filter($tags); $tags = array_map('trim', $tags); $item['tags'] = $tags; } ! // clean date_joined format $date = new DateTime($item['date_joined']); $item['date_joined_clean'] = $date->format('Y-m-d'); ! return $item; }
  • 20. 3. Convert to XML // output XML $xml = new toXml("profiles", "profile"); $xml->setHandler("tags", "tagHandler"); $xml->convert($items); echo $xml->saveXML(); Musketeers.me
  • 21. 4. Save XML Output Musketeers.me $ php csv2xml.php > profiles.xml <?xml version="1.0"?>! <profiles>! <profile>! <first_name>Whilemina</first_name>! <last_name>Benton</last_name>! <email>sollicitudin.orci@arcuiaculisenim.ca</email>! <city>Ansfelden</city>! <country>Sri Lanka</country>! <date_joined>12/25/13</date_joined>! <company>Vivamus Institute</company>! <bio>amet nulla.

  • 22. Our Profile Content Type • Text fields: First Name, Last Name, City, Country, Company • Email field: E-mail • Date field: Date Joined • Long Text: bio • List: Tags (roles) • Integer: Legacy ID Musketeers.me
  • 23. Musketeers.me
  • 24. Step 4. Configure Feeds • Basic: Disable periodic import • Fetcher: File Upload • Parser: XPath XML Parser • Processor: Node processor Musketeers.me
  • 25. 5. Configure Processor • Settings • Bundle: Target content type • Update: Update existing nodes • Text format: HTML • Expire Nodes: never Musketeers.me
  • 26. 6. Map Source to Target Musketeers.me
  • 27. 7. Map Inputs with XPath Musketeers.me
  • 28. An XPath Primer • Used to query XML documents • A path can return multiple nodes • /profiles/profile - give me all profile nodes • Can test for attributes, elements, and more • http://github.com/GeorgeMac/xpath-primer Musketeers.me
  • 29. 8. Run the Import Musketeers.me
  • 30. Advanced Feeds Tricks • Provide a URL to an image, audio, or other media file, and it’ll download automatically. • Can create entity references • As long as your GUIDs are set • Can import to Field Collection • https://drupal.org/project/field_collection_feeds Musketeers.me
  • 31. hook_feeds_presave • Clean up data on import • Can also use regular node hooks function grad_importers_feeds_presave(FeedsSource $source, $entity, $item) {! if ('publications' == $source->id) {! // ensure yes/no fields are imported! $entity->field_submitted_web[LANGUAGE_NONE][0]['value'] = (int) $item['xpathparser:5'];! $entity->field_media_promotion[LANGUAGE_NONE][0]['value'] = (int) $item['xpathparser:6'];! Musketeers.me ! // don't lose freeform notes but import the values cleanly! $notes = array_filter(array($item['xpathparser:8'], $item['xpathparser:12']));! $entity->field_history_notes[LANGUAGE_NONE][0]['value'] = join("n", $notes);! }! }
  • 32. hook_feeds_presave II • Extract data from a field, assign it to another function foo_feeds_presave(FeedsSource $source, $entity, $item) {! if ('news_feed' == $source->id) {! // get link and title out of the description field! $doc = new DOMDocument();! $x = @$doc->loadHTML($item['xpathparser:2']);! Musketeers.me ! $links = $doc->getElementsByTagName('a');! if ($link = $links->item(0)) {! $entity->field_link['und'][0]['title'] = $link->nodeValue;! $entity->field_link['und'][0]['url'] ! = $link->attributes->getNamedItem('href')->nodeValue;! }! }! }
  • 33. Creating an Entity Reference • Map a source to a Feeds GUID ! ! • Set an XPATH query to read the GUID Musketeers.me
  • 34. Entity Reference XML <scholars> ! <scholar>! <scholar_id>b36c6b08b402c12bd3a11657420cd5dd</scholar_id>! <scholar_name>Sammy Zahran, PhD</scholar_name>! </scholar>! </scholars>! <program_id>ee01cb8d56dbd67bf89c3c4fcf69e2f5</program_id>! </publication> Musketeers.me
  • 35. What about Drupal 8? • Import API is in core • Based on Migrate API • http://groups.drupal.org/imp • Porting Feeds module • http://drupal.org/node/1960800 Musketeers.me
  • 36. What did we learn? • Decouple your source from import • Sources will change … versioning! • Transform input sources to XML • Clean up data with PHP before it gets to Drupal. • Quicker & easier to run more than one import Musketeers.me
  • 37. Thank You. • php[architect] - http://phparch.com • Magazine, books, trainings, and … • php[world] - this November • http://world.phparch.com • PHP Foundation for Drupal 8 • 2 days of training • http://phpa.me/drupal8dec14
