How to use numeric values on page reference field selector?

[Hubris]

Hi there!

I'm using some page reference fields to create lists of tags, categories, years, etc.. I'm able to find the pages like so:

$pages->find("template=project, {$filter}={$page->title}");

Which dynamically does something like: 

$pages->find("template=project, tags=Experimental");

Only if the value (the page name, like "Experimental") starts with letters. If it starts with numbers, find returns nothing.

Why is this and how can I fix it?

No problem here finding matches for a Page Reference field containing pages whose title starts with numbers. If the search value only contains numbers then the value will be interpreted as a page ID.

In any case it's good to be specific about what you are wanting to match against to avoid any confusion. So if you want to match against the title use tags.title as $filter in your example.

Correction for future reference: indeed, with only numbers.

I thought it was about being interpreted as page ID, but a type conversion thing. I have no ideia how I missed subfield selectors... -_-

Thank you!
