Example "Custom PHP code" for Page Reference field fails inside repeater

[Toutouwai]

Short description of the issue

When using the "Custom PHP code" option to limit selectable pages for a Page Reference field, the example code given is:

$wire->addHookAfter('InputfieldPage::getSelectablePages', function($event) {
  if($event->object->name == 'my_page_field') {
    $event->return = $event->pages->find('your selector here');
  }
});

But the if() condition will fail when the field is contained within a repeater item because in that case the inputfield name will be my_page_field_repeater1234. Users may not know how to debug this issue and it would be better if the example code worked for all contexts where a Page Reference field may be used.

Optional: Suggestion for a possible fix

While the inputfield name changes when used inside a repeater, the name of the field associated with the inputfield does not change. So perhaps the example code could be changed to:

$wire->addHookAfter('InputfieldPage::getSelectablePages', function($event) {
  if($event->object->hasField->name == 'my_page_field') {
    $event->return = $event->pages->find('your selector here');
  }
});

Thanks, good suggestion, I have updated that example.

I post it here cause i think its releated.
When i set the field to "Page Autocomplete" this hook
(InputfieldPage::getSelectablePages)
isn't called at all.
