So how would I make it increment a field in the user table called money each time a user posts? It seems that it should be something like this, but I have minimal knowledge of php & mySQL.
Code:
$money = $this->fetch_field('money', 'user');
$user->set('money', 'money + 1');
I don't fully understand what all that code means. I've used the code in the other classes as examples when I came up with that.
