Error listing files with Google Drive API (PHP)

Question

I'm trying to list files in Google Drive using Google's PHP API (https://developers.google.com/drive/v2/web/quickstart/php).

I've managed to obtain a scoped access token, but the sample code Google provides for listing files (https://developers.google.com/drive/v2/reference/files/list#response) is returning an error.

Here is my code:

$client = new Google_Client(); $client->setAuthConfigFile('/usr/share/nginx/google.json'); $client->setAccessToken($a4e->user->google_token); // access token scoped for DRIVE_READONLY $drive_service = new Google_Service_Drive($client); $files=retrieveAllFiles($drive_service); var_dump($files); function retrieveAllFiles($service) { $result = array(); $pageToken = NULL; do { try { $parameters = array(); if ($pageToken) { $parameters['pageToken'] = $pageToken; } $files = $service->files->listFiles($parameters); $result = array_merge($result, $files->getItems()); $pageToken = $files->getNextPageToken(); } catch (Exception $e) { print "An error occurred: " . $e->getMessage(); $pageToken = NULL; } } while ($pageToken); return $result; }

This returns the following error:

Fatal error: Call to undefined method Google_Service_Drive_FileList::getItems() in /usr/share/nginx/html/tools/google/index.php on line 30

Does anyone know what I'm doing wrong?

Many thanks in advance.

I guess you are using Drive API V3 and trying to invoke a method of version V2 in V3 . Clearly look in the documentation , the Drive API V2 returns response in following format { "kind": "drive#fileList", "etag": etag, "selfLink": string, "nextPageToken": string, "nextLink": string, "items": [ files Resource ] } So you can do a $files->getItems() in V2 . But the Drive API V3 return response for listing in following format { "kind": "drive#fileList", "nextPageToken": string, "files": [ files Resource ] } So , you may need to do a $files->getFiles(). Give it a try !! I hope this will work . For your reference Drive API V3 Listing Response Drive API V2 Listing Response . Let me know if issue is resolved .

Thank you! This did the trick. I didn't realize I was trying to use code from the wrong version of the API - I'll be more careful next time. Thanks for helping me fix this issue!
