Removed reference to deleted template w:en:Template:Familia

New page

{{H:h|editor toc}}

This is a quick '''overview of templates'''. Full details can be found in '''[[Help:Template]]''' and '''[[Help:Advanced templates]]'''.

Templates are pages in the template [[Help:Namespace|namespace]]. This means any page beginning with "Template:", such as <nowiki>[[Template:Templatename]]</nowiki> can be used as a template. The content of a template can be added to a page by typing <nowiki>{{templatename}}</nowiki>.

Templates are used to add recurring messages to pages in a consistent way, to add boilerplate messages, to create navigational boxes and to provide cross-language portability of texts.

==Creating, editing and using templates==
You start a new template in the same way you would [[Help:Starting a new page|start a normal page]]. The only difference is that its title must start with <tt>Template:</tt>.

Once you have made the template, you can add <nowiki>{{</nowiki>''templatename''<nowiki>}}</nowiki> to the pages you want to use it on. Every page using this template will get the same boilerplate text, each time a user visits it. When the template is updated, all pages containing the template tag will be automatically updated.

Alternatively, you can add <nowiki>{{</nowiki>subst:''templatename''<nowiki>}}</nowiki> to the pages you want to use the boilerplate text on. The system will fetch a one-time copy of the template text and '''substitute''' it into the page, in place of the template tag. If anyone edits the template afterwards, pages that used the <tt>subst:</tt> keyword will '''not be updated'''. Sometimes that's what you want.

If the template you want to edit looks like <nowiki>{{foo}}</nowiki>, you would go to [[Template:foo]] to edit it. To get there, type in the URL to your address bar, [[Help:Searching|search]] for it, or make a link in the [[{{ns:4}}:sandbox|sandbox]] and click on it.

Once you are there, just click "edit" or "edit this page" and edit it in the same way you would any other page. You can add anything you would add to a normal page, including text, images and other templates. Please be aware that your edit might affect many pages, so be cautious.

==FAQ==
;Can I use a template in more than one project? : No, if you want to use it on two different language Wikipedias, for example, you would need to create it twice.
; Are templates case sensitive? : Yes, except usually the first letter.
; Can I add parameters? : Yes, see [[Help:Template]] for instructions.
; How many templates can I use in a page? : As many as you like (in older versions you could not use the ''same one'' more than 5 times).
; I edited the template, so why didn't the page it is used on change? : There are some caching bugs – solutions include:
:;[[Help:Dummy edit#Null edit|Null edit]]: One way to force refresh is to do a '''null edit''' – '''edit''' on the page in which the template appears, and to then click on '''Save page''' without having changed anything – there is no need to fill in the ''Summary'' field since there will not be any ''history'' of this as a change generated.
:;[[w:Wikipedia:Bypass your cache|Reload]]: Alternatively, '''refreshing''' by pressing Ctrl and F5 often helps.
:;[[w:Wikipedia:Purge|Purge]]:Another way is '''purge,''' by adding "&action=purge" to the address, like you would for "&action=edit" (e.g, :index.php?title=foo&action=purge).
; Can I move a template to a new name? : Yes, this works in exactly the same way as normal [[Help:Renaming (moving) a page|page moves]]. When a page called for inclusion is a redirect page, the redirect target is included instead.
; Can I use a template within a template? : You can use a template tag within template content, but not within a template tag: in the latter case the parser will prematurely end the original template tag when it reaches the first pair of curly closing braces....
;How do I add a new template?: You start a new template in the same way you would start a normal page. The only difference is that its title must start with Template:.
; Where is the manual for the programming language used to write templates?: The language inside templates is the same language as regular wiki markup, but template writers tend to use the more complex available functions such as #if: statements. See [[m:help:ParserFunctions|ParserFunctions]] and see the other "advanced functioning" help pages listed below.

==Examples==

*[[w:en:Template:stub]]: an often used message
*[[w:en:Template:europe]]: a navigational template
*[[w:cy:Template:Dosbarthiad_biolegol]]: a template with parameters
*[[fr:Modèle:Familia]]: cross-language templates
*[[eo:Ŝablono:El]]: a small, often used image
*[[b:en:Template:GeneralChemTOC]]: a horizontal menu bar
