Page fieldtype output?

[alejandro]

Mmmm, again lost...

In the template "Product" there is a Page field "Teacher", which lists the teachers pages.

The page "Yoga" has assigned the template "Product" and selected a teacher.

Then how could I output the related page in the Yoga page?

$page->teacher;
 

This outputs nothing...

Can´t find a reference in the docs about this field type.

It's strange that it outputs nothing. It should output the page ID.

To output the title, for instance, you would do this:

$page->teacher->title;

[kongondo]

Yes, it should output at least the page id(s). No errors? Of course you have to echo it out  first

Btw, I thought there was something in the docs about page reference field types? I can't find it now. Or was it a video?

Other questions...

is that a single or multiple page select? If the latter, it returns a page array hence needs looping through. 

[alejandro]

Aaaaah, again a silly mistake...

The field is named "Teacher"...wrote "teacher" in code... code is case-sensitive... error!

I guess  is time to sleep.

Thanks and sorry for the dumb question.

PD There is a video about Page field types, pointing to cities related pages, but only in the admin side, no code shown.

Well, i found the reference to Page Field in the documents, is in the wiki. I was learning PW following the API and Videos docs, as there are no link to the wiki in the PW home.

I'm in the process of converting everything in the Wiki over to the main site. The Wiki is getting all kinds of strange traffic from the logs, and it's database is many gigabytes in size (when it should be more like a megabyte). Basically, I don't trust MediaWiki here, at least since I'm not an expert with it. I'd feel more comfortable having all this content on the main site, so it should be there soon.

Didn´t know about that issue with MediaWiki but I thought it was strange to split the docs into different sources. I'd be great to have it all in the main site. I believe that for newcomers/newbies/starters, a detailed, comprehensive and easy to find documentation is invaluable; even more if you are a graphic designer and need baby steps to advance.

I agree. Maybe we could manage to make the docs on the website semi-collaborative by creating a "docs collaboration" forum, from where some things would be added to the website after discussion and approval. People seem to be much more active here than in the comments on the website.
