Bla bla bla. Your message was so long it was truncated by my mobile email client. What I think the original poster means is the links displayed below the title, like Page | Subpage. Simple as that.

Earlier: if I have a page A, and I create a subpage, A/B/C, but A/B does not exist, then A/B/C will automatically link back to A, but not A/B, since it doesn't exist.
Yes.
The question is, what happens if I now create A/B after A/B/C is already created. Will the wiki recognize that A/B/C is a subpage of A/B?
Yes.
Peter Blaise asks:
Q1: you say that a subpage automatically *links* back to the page it's a sub of? What do you mean by *links*? I see no auto anything on my subpages or on the pages they are a subpage of (v1.10.0). Can you show an example of what "automatically *link* back" looks like?
Q2: And why would we do this? What tools in MediaWiki help us search, sort and select/display/print the data that is organized as subpages such as "a", "a/b", and "a/b/c"?
I just built these pages and a few more to experiment:
a a/b a/b/c a/a a/b/a a/b/b a/a/a/a a/a/a/b b b/a b/a/a b/a/b b/b b/b/a b/b/b b/b/c
... and so on, for way more pages than I probably need (I have a lot of cleaning up to do after this test!).
On each "a" page I put the word "ardvark". On each "b" page I put the word "bayonette". On each "c" page I put the word "carlisle".
... and so on. These are words I knew were NOT in my wiki otherwise (hey, misspellings can be useful during testing).
Results:
ALL these pages, including sub pages, show up in [[special:allpages]].
A [search] for ardvark, bayonette or carlisle finds ALL pages,
including sub pages, that contain the words searched for.
I cannot divine a MediaWiki-native way to show ONLY pages below "a" or ONLY pages below "a/b" or any other limit or control of focus over where the search/sort/select looks. (v1.10.0)
Q3: Does anyone know of tools within MediaWiki (or extensions) that provide such a result? I thought someone mentioned that subpages automatically get a listing in or to the article/page they are an subpage of, but that's not happening (v1.10.0)
As far as I can tell, a value for me of a subpage is to allow me to have otherwise identically named subpages under different articles with otherwise different contents, like this list of article/pages keeping track of, say, computer resources:
Computer1 Computer1/hardware-inventory Computer1/service-history Computer1/software-inventory Computer1/user-list Computer2 Computer2/hardware-inventory Computer2/service-history Computer2/software-inventory Computer2/user-list Computer3 Computer3/hardware-inventory Computer3/service-history Computer3/software-inventory Computer3/user-list
Q4: how would I list all pages ONLY under Computer1, for instance? (Read on, I found an answer.)
A4: I found this extension:
http://www.mediawiki.org/wiki/Extension:SubPageList2
... and found it's php file here:
http://stuff.schaelle.de/SubPageList2/SubPageList2.zip
... and put it's php file here:
..\extensions\subPage2.php
... and added the following lines using a text editor to ..\LocalSettings.php
# for SubPageList extension require_once("extensions/SubPageList2.php");
Then I confirmed by using [[Special:Version]] and saw:
Subpage List 2 Martin Schallnahs, Rob Church
Thanks, Martin and Rob! Then, after printing and reading the "documentation" and casting out much that failed to work as described, I found that THIS worked when typed in as the text contents of a page that has subpages:
<subpages deepness=1 />
And then I see THIS as it's contents when rendered (from my expanded a/b/c example above), for example, let's add those lines to page "a" - then it shows this:
A
ardvark
- A/a
- A/a/a/a
- A/a/a/a/z
- A/a/a/b
- A/b
- A/b/a
- A/b/b
- A/b/c
- A/z
... where all the "- " lines shown above are actually live blue links to the subpages. THIS I can use to show a clickable table of contents list of all subpages under, say, Computer1. GREAT!
Q5: How would I list all "*/hardware-inventory" pages only?
A5: I could create a category and categorize them, then the special page [[Category:Service-history]] will display a clickable table of contents, and the fact that they are all subpages is irrelevant:
Articles in category "Service-history"
There are 3 articles in this category.
C
Computer1/service-history Computer2/service-history Computer3/service-history
Good. Unless, I also have a <subpages/> command IN the "Computer1" article page, which I want to do. Then, the <subpages/> command bets interpreted first, ad MediaWiki thinks the "computer1" page also is in the [[category:service-history]]:
Articles in category "Service-history"
There are 6 articles in this category.
C Computer1 Computer1/service-history Computer2 Computer2/service-history Computer3 Computer3/service-history
Lesson? Plan my nesting carefully, and maybe learn to modify and enhance the extension to make it more disciplined.
Now, oddly enough, it seems that the "subpages" extension is smarter in a dumb way in that I just tried a sample article/page called "z" and added to it's text contents merely <subpages /> and got a list of ONLY other pages at the same level (immediately "under" the main namespace) which happen to also have "z" in their titles - anywhere within the title! But no subpages! Cool. This feature could make a strange indexer or sorts.
But when I type THIS into the text of *any* page:
<subpages parent=a />
I get this:
- A/a/a/a
- A/a/a/a/z
- A/a/a/b
- B/a/a
Not "all children of any 'a' page" as I expected, but sort of, "only all *terminus* pages whose *immediate* parent is an 'a' page". Weird. I was expecting "all sub pages of any 'a' parent", which SHOULD have yielded:
- A
- A/a
- A/a/a
- A/a/a/a
- A/a/a/a/z
- A/a/a/b
- B/a/a
THIS odd behavior is why I've been so often frustrated when trying to follow directions but have gotten different results than the original programmer got in their environment - change ONE thing and all logic falls away! =8^o
Q6: How to get the list above, "all subpages of any parent named 'a'", on demand?
I also tried simplifying using the "showpath=no" argument:
<subpages parent=a showpath=no />
But that just returns:
- a
- z
- b
- a
Which is which? So, "showpath=no" seems a tough option to find value for in my examples.
So, as hinted to above in the category exploration, the funny thing about the <subpages /> command is, if they are called or nested, the <subpages /> command seems to get interpreted/parsed as if it was on the calling page, not on the page where it sits. For example, on page "a/b" containing only the text <subpages />, when I open the page directly, it shows a list as expected with only itself and it's own subpages, like this:
A/b
ardvark bayonette
- A/b
- A/b/a
- A/b/b
- A/b/c
Yet, when this "a/b" page gets called, nested, found, referred to, and or included in another article/page's list, then it gets interpreted/parsed as if it were resting in/on the CALLING page, no longer as if it were on it's own original the "a/b" page. Argh! Example, if on page "a" I put something like:
<subpages deepness=1 />
I get a list of subpages under the current "a" page":
A
ardvark
- A/a
- A/a/a/a
- A/a/a/b
- A/b
- A/b/a
- A/b/b
- A/b/c
- A/z
BUT, if in page "a" I add the preview feature:
<subpages deepness=1 mode=preview />
It shows the contest of each subpage, but when it shows the contents of the subpage "a/b" in the list, "a/b" call for showing <subpages /> suddenly shows all subpages of the entire "main namespace" equal in level to the calling "a" page, not to the original source of just the subpages of "a/b"!
So, I must be careful not to nest the subpage extension command else it will behave differently than expected when it's not nested.
Thanks for exploring.
