Page save() inside of a before SavePageField hook prevents from saving the field

[Ivan Gretsky]

Good day!

I have a hook

addHookBefore('FieldtypeMulti::savePageField'...

Inside that hook I need to  create and save an additional page.

If I add that code to the hook, on the original page save the changes to Page field do not get saved. All other fields do. If I change hook to After the problem goes away. But I have so much code now I do not know if it is safe to change hook to run after the method.

If anyone has any guesses, why is it like that and how to fix it, please help!

Works fine for me in an auto-load module in ProcessWire 3.0.42 using the code below. All fields are saved correctly, both page and non-page fields.

public function init() {
  $this->pages->addHookBefore("FieldtypeMulti::savePageField", $this, "hookBefore");
}

public function hookBefore(HookEvent $event) {
  $page = $event->arguments[0];
  $this->newPage($page);// calls method to create new page
  $this->message("we hooked into page with id: {$page->id}");
}	

public function newPage($parent) {
  $p = new Page();
  $p->template = 'basic-page';
  $p->parent = $parent;
  $p->title = 'Test Child Page';
  $p->save();
}
