18.5. Using Google Documents List Data API

You can get a list of the Google Documents for a particular user by using the getDocumentListFeed method of the docs service. The service will return a Zend_Gdata_Docs_DocumentListFeed object containing a list of documents associated with the authenticated user.

$service = Zend_Gdata_Docs::AUTH_SERVICE_NAME;
$client = Zend_Gdata_ClientLogin::getHttpClient($user, $pass, $service);
$docs = new Zend_Gdata_Docs($client);
$feed = $docs->getDocumentListFeed();

        

The resulting Zend_Gdata_Docs_DocumentListFeed object represents the response from the server. This feed contains a list of Zend_Gdata_Docs_DocumentListEntry objects ($feed->entries), each of which represents a single Google Document.

You can create a new Google Document by uploading a word processing document, spreadsheet, or presentation. This example is from the interactive Docs.php sample which comes with the library. It demonstrates uploading a file and printing information about the result from the server.

/**
 * Upload the specified document
 *
 * @param Zend_Gdata_Docs $docs The service object to use for communicating
 *     with the Google Documents server.
 * @param boolean $html True if output should be formatted for display in a
 *     web browser.
 * @param string $originalFileName The name of the file to be uploaded. The
 *     mime type of the file is determined from the extension on this file
 *     name. For example, test.csv is uploaded as a comma seperated volume
 *     and converted into a spreadsheet.
 * @param string $temporaryFileLocation (optional) The file in which the
 *     data for the document is stored. This is used when the file has been
 *     uploaded from the client's machine to the server and is stored in
 *     a temporary file which does not have an extension. If this parameter
 *     is null, the file is read from the originalFileName.
 */
function uploadDocument($docs, $html, $originalFileName,
                        $temporaryFileLocation) {
  $fileToUpload = $originalFileName;
  if ($temporaryFileLocation) {
    $fileToUpload = $temporaryFileLocation;
  }

  // Upload the file and convert it into a Google Document. The original
  // file name is used as the title of the document and the mime type
  // is determined based on the extension on the original file name.
  $newDocumentEntry = $docs->uploadFile($fileToUpload, $originalFileName,
      null, Zend_Gdata_Docs::DOCUMENTS_LIST_FEED_URI);

  echo "New Document Title: ";

  if ($html) {
      // Find the URL of the HTML view of this document.
      $alternateLink = '';
      foreach ($newDocumentEntry->link as $link) {
          if ($link->getRel() === 'alternate') {
              $alternateLink = $link->getHref();
          }
      }
      // Make the title link to the document on docs.google.com.
      echo "<a href=\"$alternateLink\">\n";
  }
  echo $newDocumentEntry->title."\n";
  if ($html) {echo "</a>\n";}
}

        

You can search the Document List using some of the standard Google Data API query parameters. Categories are used to restrict the type of document (word processor document, spreadsheet) returned. The full-text query string is used to search the content of all the documents. More detailed information on parameters specific to the Documents List can be found in the Documents List Data API Reference Guide.

$feed = $docs->getDocumentListFeed(
    'http://docs.google.com/feeds/documents/private/full/-/document');

            

$feed = $docs->getDocumentListFeed(
    'http://docs.google.com/feeds/documents/private/full/-/spreadsheet');

            

$docsQuery = new Zend_Gdata_Docs_Query();
$docsQuery->setQuery($query);
$feed = $client->getDocumentListFeed($docsQuery);
