টেমপ্লেট:When on basepage

টেমপ্লেট নথি[দেখুন] [সম্পাদনা] [ইতিহাস] [শোধন]

This is the {{When on basepage}} meta-template. It helps other templates detect if they are on a basepage (i.e. a page whose name matches the pattern "x:x") subpage ("x:x/x") or subsubpage ("x:x/x/x").

An alternative way to detect whether a page is a subpage is to combine the parser functions #ifeq: and #titleparts. See Alternatives for simpler text below.

{{When on basepage |result if on a basepage (|result if on a subpage) (|result if on a subsubpage) (|page=pagename)}}

For example, {{When on basepage|Basepage|Subpage}} on the page "User:Example" would return: Basepage
whilst on "User:Example/page" (or "User:Example/page/page", "User:Example/page/page/page", etc) it would return: Subpage

On a subsubpage such as "User:Example/page/page" (or "User:Example/page/page/page", etc), {{When on basepage|Basepage|Subpage|Subsubpage}} would return: Subsubpage

Use an empty parameter to specify no action for a particular type of page. {{When on basepage|Basepage||Subsubpage}} on "User:Example/page", for example, would return nothing, but would return "Subsubpage" if on "User:Example/page/page", "User:Example/page/page/page", etc (and "Basepage" if on "User:Example").

Use numbered parameters if their values include equals-signs ("="), i.e.

{{When on basepage |1=basepage result (|2=subpage result) (|3=subsubpage result)}}

The page parameter is included for testing/demonstration. For example:

{{When on basepage |(basepage result)|(subpage result)|page=User:Example/test}}

Regardless of where the above is placed, it will return: (subpage result)
(because "User:Example/test" is a subpage). The page doesn't have to exist.

If page is left empty (|page=) or undefined, the page where the template is transcluded (i.e. purge rev-ID : -   b: c: m: n: q: s: t: w: wikt: ? – version all messages

প্রযুক্তিগত নোট

This template detects subpages in all namespaces, including those without the MediaWiki subpage feature enabled.

সহজ টেক্সট জন্য বিকল্প

A subpage can be detected without using another template, by instead using the title-splitting parser function #titleparts with #ifeq:

{{#ifeq:{{#titleparts:{{PAGENAME}}|1|1}}|{{PAGENAME}}
 | [...code if on a basepage...]
 | [...code if on a subpage...]
}}

For example, many templates can check if the page is a /sandbox version, by the similar markup with #ifeq and #titleparts:

{{#ifeq: {{#titleparts:{{PAGENAME}}|1|1}} | {{PAGENAME}}

| {{documentation}}

| {{template sandbox notice}}

}}

That simple logic works because Template:Template_sandbox_notice also checks the page name for "/sandbox" before displaying the sandbox notice; otherwise, any other subpage would show no extra text. By avoiding a template, and using a single #ifeq, then the processing uses only +2 expansion depth levels, rather than +7 levels, and avoids "wp:exceeded template limits" inside a complex /doc page.
