  1. Hi everybody! And thanks for Processwire! There's a kind of bug or incorrect behavior associated with hooks for Page Reference fields. The Page Reference field stores references for PW page(s), sorry for being so banal. This kind of field needs some rules to fetch PW pages which will be available as content of inputfield. There are some possibilities to fetch that pages: by choosing their parent by choosing their template by custom find procedure having a nice user interface by PW selector string by custom PHP code Let's now focus on the last 5th option. In this case we should add some PHP code to /site/ready.php . Just an example from PW docs: $wire->addHookAfter('InputfieldPage::getSelectablePages', function($event) { if($event->object->hasField == 'cloth') { $event->return = $event->pages->find('your selector here'); } }); Up to this point, the things are simple and easy. But what if we will try something more complex? ... $event->return = $event->arguments('page')->parents('template=product')->first()->findOne('name=clothes,include=all')->children('template=cloth'); ... It's an excerpt from my real hook. I tested it both outside of the hook and inside it, it works (fetches the pages i need). But when i try so edit and/or to save my Page Reference field which uses that hook, i get an error of this kind: Fatal Error: Uncaught Error: Call to a member function find() on bool One more time: the above-cited piece of php code is correct. It populates my inputfield with the desired page references, the pages having that pagefield can be saved, fetched and so on. The only problem is that fatal error during save/edit of pagefield itself. I can suppose that this error takes place because the above-cited custom php code deals with some parent page(s). It works when the inputfield is used by non-admin PW page having correct parent(s) expected by cutom php code, but fails when we're trying to work with the admin PW page representing this inputfield itself. If so, we can consider a kind of "sandbox" for custom php code of this kind. Ideally, it shouldn't give us a fatal error even if it's incorrect. It should better throw an exception and output a warning, still giving us possibility to edit/save the inputfield admin page. Any ideas are welcome. Thanks in advance!
  2. Custom PHP code is available for use in PageReference field type. Is it possible to use custom php to generate the values for a Select Options FieldType?? What I'm to trying to achieve is to generate values for a options field from values for repeater in a grand parent's page (parent of parent page).
