[Contacts API] Get all contacts from a group

[Samuel Bolduc]

Hi,

I'm starting with Google APIs, and I'm trying to get all the contacts from 
a group, but so far I didn't succeed. The best I can do is get a list of 
the groups. Here's the code :

$query = new Zend_Gdata_Query(
>
>         "https://www.google.com/m8/feeds/groups/default/full";);
>
>       $feed = $gdata->getFeed($query);
>
>
>  
With this (https://www.google.com/m8/feeds/groups/default/full), I get the 
list of groups. With https://www.google.com/m8/feeds/contacts/default/full, 
I get all the contacts. But I can't figure out how to get contacts from a 
particular group. I 
tried https://www.google.com/m8/feeds/groups/default/base/782cb7b30e3c8be5 
(group id) but it gives me an error "ERROR:No root element". Can you point 
what's wrong to me? Thanks!

 Here's the complete code I took and edited for this :

    <?php
    // load Zend Gdata libraries
    require_once 'Zend/Loader.php';
    Zend_Loader::loadClass('Zend_Gdata');
    Zend_Loader::loadClass('Zend_Gdata_ClientLogin');
    Zend_Loader::loadClass('Zend_Http_Client');
    Zend_Loader::loadClass('Zend_Gdata_Query');
    Zend_Loader::loadClass('Zend_Gdata_Feed');
    
    // set credentials for ClientLogin authentication
    $user = "xxxxx...@gmail.com";
    $pass = "xxxxxxxx";
    
    try {
      // perform login and set protocol version to 3.0
      $client = Zend_Gdata_ClientLogin::getHttpClient(
        $user, $pass, 'cp');
      $gdata = new Zend_Gdata($client);
      $gdata->setMajorProtocolVersion(3);
      
      // perform query and get result feed
      $query = new Zend_Gdata_Query(
        
"https://www.google.com/m8/feeds/groups/default/base/782cb7b30e3c8be5";);
      $feed = $gdata->getFeed($query);
      
      // display title and result count
      ?>
      
      <h2><?php echo $feed->title; ?></h2>
      <div>
      <?php echo $feed->totalResults; ?> contact(s) found.
      </div>
      
      <?php
      // parse feed and extract contact information
      // into simpler objects
      $results = array();
      foreach($feed as $entry){
        $xml = simplexml_load_string($entry->getXML());
        $obj = new stdClass;
        $obj->id = (string) $entry->id;
        $obj->name = (string) $entry->title;
        $obj->orgName = (string) $xml->organization->orgName; 
        $obj->orgTitle = (string) $xml->organization->orgTitle; 
      
        foreach ($xml->email as $e) {
          $obj->emailAddress[] = (string) $e['address'];
        }
        
        foreach ($xml->phoneNumber as $p) {
          $obj->phoneNumber[] = (string) $p;
        }
        foreach ($xml->website as $w) {
          $obj->website[] = (string) $w['href'];
        }
        
        $results[] = $obj;  
      }
    } catch (Exception $e) {
      die('ERROR:' . $e->getMessage());  
    }
    ?>
