Save user profile fields through plugin

Question

I have added additional fields to my user profiles. I need to be able to change and save these via my plugin. How do I set those values before calling

craft()->users->saveUser($user);

Answer 1

You use setContentFromPost method on the UserModel if you are posting to your plugin, like so (this is what happens when you save your profile in the control panel):

$user->setContentFromPost('fields');

There is also a setContent method, which takes a ContentModel or an array:

$user->setContent([ 'fields' => ['field1' => 'value'] ])

Behind the scenes, that runs the setAttributes method.

Answer 2

Fred got me pointed down a path. Not sure why this works, perhaps someone can explain it to me. This is what I ended up doing.

$initialCredits = 100;
$user = craft()->users->getUserById(craft()->userSession->getUser()->id);
$user->getContent()->initialCredits = $initialCredits;  
craft()->users->saveUser($user);

Now, why getContent() worked and setContent() doesn't confuses me. I would think that since I am setting content and not getting it, I should use getContent(). Unless I am on the other side of the model somehow.

Answer 3

Fred is definitely on the right path -- the setContent() call works just fine and makes a lot more sense then using getContent():

$initialCredits = 100;
$user = craft()->userSession->getUser();
$user->setContent(['initialCredits' => $initialCredits]);
craft()->users->saveUser($user);

P.S. The way you're getting the current user is redundant. Just use craft()->userSession->getUser() instead.
