Issues with 2/files/list_folder/continue & cursor
I have a web app that does the following in order:
1. Login user via "login via dropbox" link
2. Get and save latest cursor
3. Call 2/files/list_folder/continue as needed using latest curso...
Hi Greg,
Sorry for the lack of information.
I'm using PHP with no library (just CURL)
Snipper
$data = '{"cursor": "' . $cursor . '"}';
$ch = curl_init('https://api.dropboxapi.com/2/files/list_folder/continue');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Authorization: Bearer ' . $token, 'Content-Type: application/json'));
$json = curl_exec($ch);
$result = json_decode($json, true);
$new_cursor = $result['cursor'];
There are no errors. However, the next time i call list_folder/continue with the new cursor, i get a history fo all changes previously. Not just recent changes.
Thoughts?

Dropbox StaffThanks! I just tried this, and I can't seem to reproduce this issue with this code though.
Are you sure the first call is succeeding? I don't see any error handling in this snippet.
Also, how are you copying $new_cursor to $cursor? I don't see that in this sample either. Are you sure that's working properly?

- Hi Greg,
That's just a snippet in a class file. So essentially what im doing is this
1. Log user in, get latest cursor and save to database locally
2. Once a user makes changes, a webhook is sent and the locally stored cursor is used for the list_folder/continue call
3. Update cursor for user
Now when another change is initiated, making a call with the new cursor still shows ALL changes, not just latest.
I think i'm just using the wrong cursor, but need to confirm.
Should I..
Make API call then save cursor given by list_folder/continue
Or
Make list_folder/continue API call, then do another to get_latest_cursor and save that cursor.- Disregard. I was not saving the latest cursor properly. I was using the wrong column name "user_id" vs "id" in the user table.
Sorry for the trouble and will add error handling asap.
