Changing a username and profile picture

    Currently, I found out that the easiest way to change a username was to update `xf_user` and set the username to the new username, which then will update across the board accordingly.

    However, is this the best way to do it though?

    Also, I need to be able to change their profile picture to something else. I have their new profile picture at https://example.com/profiles/<username>/, but I cannot seem to find any way to update their profile picture.

    Are you writing an add-on?

    If so, you should look at how user name changes are handled in code when updated via the ACP.

    You should definitely use the DataWriter to do things like this:

    $userWriter = XenForo_DataWriter::create('XenForo_DataWriter_User');
    $userWriter->set('username', $newUsername);
    as there is more that may end up changing than just the 'username' field in xf_user.

    Is there any way I can set the avatar?

    Look around in XenForo_Model_Avatar and XenForo_ControllerPublic_Account

    This is what I have:
            $visitor = XenForo_Visitor::getInstance();
            $tempFileName = md5(mt_rand(1, 99999999) . time()) . "-fv-avatar.png";
            file_put_contents("/tmp/" . $tempFileName, file_get_contents("https://example.com/avatar/" . $visitor['username']));
            $avatarModel = XenForo_Model::create('XenForo_Model_Avatar');
            $source = array(
                "avatar" => array(
                    "name" => $visitor['user_id'] . ".png",
                    "tmp_name" => "/tmp/" . $tempFileName,
            $avatar = XenForo_Upload::getUploadedFile('avatar', $source);
            $avatarData = $avatarModel->uploadAvatar($avatar, $visitor['user_id'], $visitor->getPermissions());
    It works correctly from what I can see, is there anything I can do to improve it?

    Well, if this is something you plan on releasing you should probably not use file_get_contents on a url, but instead use cURL

    This is just a private thing I'm doing for my forum. I tried using cURL first, but the picture kept on coming back corrupt with nothing inside.

    It's still a better optiont o use cURL. What was the code you were using, and where are you trying to get the image from?

    I eventually stumbled into this error: An exception occurred: Your avatar's file size is too large. Please upload an avatar no bigger than 0 bytes.

    I have the forum on default settings, and uploading an avatar manually works.

    Any ideas?
