How to set field to autojoin via API?

[Jonathan Lahijani]

I want to set a handful of fields to have the autojoin setting checked via the API, however it's not as simple as:

foreach($fields->find("name=myfield1,myfield2,myfield3") as $f) {
  $f->autojoin = 0;
  $f->save();
}

Autojoin is a flag, like system, global, etc:

$field->flags = Field::flagAutojoin;
$field->save();

Actually, you probably want

$field->addFlag(Field::flagAutojoin);
$field->save();

so you don't remove any other existing flags.
