Question

I am parsing contacts from Gmail, and creating a sync functionality with my product.
But on my script i’m having a hard time determining which contacts get ‘deleted’ from gmail.

EXAMPLE:
If I have John Doe in my Application, along with Gmail… (and they are synced with the gmailId). Later on down the road, if the user DELETES the contact John Doe, and I run my SYNC, how do I determine that the contact was deleted?

I need to know where to throw a trigger to delete the same contact within my database. I currently have this to obtain information on each contact sent through.

$xml = simplexml_load_string($entry->getXML());
$obj = new stdClass;

//    EDIT LINK
$obj->gmailUrl   = rawurlencode($entry->id);                
$obj->delete     =  (string) $xml->groupMembershipInfo['deleted'];

//    FIRST Name
$obj->firstName  = (string) $xml->name->givenName;

Previous in my code i’m also query google with these extra params.

$query->setParam('updated-min', $updatedMin);
$query->setParam('showdeleted', 'true');
$query->setParam('requirealldeleted', 'true');

Any help would be appreciated!

Answer 1

I found out that Google adds an empty XML Tag called Deleted when a contact is deleted.

Something like this.

if(isset($xml->deleted)) { $deleted = "true"; } else { $deleted = NULL; } 
$obj->delete = $deleted;

Although Adrian’s solution would work, I felt that wasn’t the best solution as I felt Google must to have an answer for this rather than checking to see if a contact was available every day.
