My problem is that I can't update the specific $userId. have the values I've selected. I also get an error:

Call to a member function where() on integer

I just started to learn Craft. It can be simple for you but not for me.

public function updateUserName($userId, $updateUser)

    $update = craft()->db->createCommand()->update('contest_user', array(
        'name' => $updateUser))->where('id', $userId);

    return $update;

When you take a look at the documentation the interface for the update function is the following.

public integer update(string $table, array $columns, mixed $conditions='', array $params=array ())

Thus your code should look like:

public function updateUserName($userId, $updateUser)
    $update = craft()->db->createCommand()->update(
        array('name' => $updateUser), 
        array(':id', $userId)

    return $update;

You can see a working example here:

// build and execute the following SQL:
// UPDATE `tbl_user` SET `name`=:name WHERE id=:id
$command->update('tbl_user', array(
), 'id=:id', array(':id'=>1));
  • Thx. It works. It's so easy when you think about it. I'm just a beginner. So there is plenty of practise to do. – olifantT Oct 16 '18 at 14:04
