Cannot set published flag to true with Google Drive API - php

Question

I have made a simple PHP script which uploads a file to Google Drive. I then run the following function:
function PublishToWeb($service, $fileId, $revisionId) {
$patchedRevision = new Google_Revision();
$patchedRevision->setPublished(true);
$patchedRevision->setPublishAuto(true);
$patchedRevision->setPublishedOutsideDomain(true);
try {
return $service->revisions->patch($fileId, $revisionId, $patchedRevision);
} catch (Exception $e) {
print "An error occurred: " . $e->getMessage();
}
return NULL;
}
I get no error message but the word document is not published.
When I try to set the flags using the Google APIs explorer it returns no errors but also fails to set the published flag to true. Am I missing something obvious?
For clarity I'm trying to upload a file then instantly simulate pressing 'Publish to web'. I also tried using revisions.update
Update:
Okay, I've figured out that the document has to be uploaded and converted to a google doc format to be published. However when the document is saved as a google doc it has no headrevisionid set so I can't use revisions.update or revisions.patch
Anyone know how to publish a google doc file?

Answer 1

Okay I figured it out.
When uploading the file convert to a google doc
$createdFile = $service->files->insert($file, array(
'data' => $data,
'convert' => 'true',
));
Then update the published flag to true
$revisionId = 1; //The revisionId for a newly created google doc will = 1
function updateRevision($service, $fileId, $revisionId) {
$patchedRevision = new Google_Revision();
$patchedRevision->setPublished(true);
$patchedRevision->setPublishAuto(true);
$patchedRevision->setPublishedOutsideDomain(true);
try {
return $service->revisions->patch($fileId, $revisionId, $patchedRevision);
} catch (Exception $e) {
print "An error occurred: " . $e->getMessage();
}
return NULL;
}
Then build the publishedlink as this isn't done for you
$PublishURL = 'https://docs.google.com/document/d/'.$fileId.'/pub';
