How to 'Custom PHP selector' current page

[fredbob]

Hi, 

In the custom PHP selector code for a PageField how do I go about selecting pages that have a field that is the page that I am currently editing.

$wire->addHookAfter('InputfieldPage::getSelectablePages', function($event) {
  if($event->object->name == 'field2') {
    $page = $event->arguments('page');
    $event->return = $event->pages->find('template=template1, field1=$page');
  }
});

Quick glance shows the first obvious problem is that you have a variable ($page) inside single quotes. You can either use double quotes, or concatenate.

find("template=template1, field1=$page");

find('template=template1, field1='.$page);

EDIT: removed code example
The code doesn't work since a page being edited is not saveable in a pagefield (circular reference).
