Ak máte štandardné texty, ktoré chcete vkladať do niekoľkých stránok, vstupuje do hry funkcia MediaWiki - šablóny. Na rozdiel od rozšírení (extensions) a multimediálnych súborov, šablóny nie sú uskladňované centrálne. Môžu byť vytvorené špeciálne pre konkrétnu wiki alebo z dôvodov šetrenia práce tiež exportované z inej wiki (napr. Wikipédie) a následne importované do cieľovej wiki.

Vytvorenie šablóny

Templates are standard wiki pages whose content is designed to be transcluded (embedded) inside other pages. Templates follow a convention that the name is prefixed with "Template:", assigning it to that namespace; besides this, you can create them like any other wiki page.

The simplest use of templates is as follows. If you create a page called "Template:Welcome" with contents:

Hello! Welcome to the wiki.

you have created your first template! If you then insert the code:


in any other page, when that page is viewed, the text "Hello! Welcome to the wiki." will appear instead of {{Welcome}}. The template content is "transcluded" into the other page, i.e., it is integrated in the page.

You can then insert {{Welcome}} at any point of any page where you wish to welcome someone. Suppose it is used in 100 pages. If you then change the template contents to:

Hi there! Welcome to this wonderful wiki.

and revisit any of the 100 pages where the template was used, you'll see the new text instead of the original one. In this way, you have changed the content of 100 pages without editing them, because the template is transcluded into these pages.

This is the basic mechanism. There are several additional features of transclusion that enrich this mechanism and make templates very useful.

Použitie šablóny

Šablóny sú stránky wiki, ktoré môžu byť použité v iných stránkach troma spôsobmi:

  • {{Názov}} 'vloží' (vloží kópiu) šablóny (uloženej na stránke [[Template:Názov]]) vždy, keď je stránka obsahujúca vloženie šablóny načítaná a zobrazená. Ak sa šablóna niekedy v budúcnosti zmení, zobrazenie stránky s vloženou šablónou sa automaticky zmení tiež.

Because the template call remains in the pages's source, any subsequent change to Template:Name will be seen on the page containing the template call. Also, the page will be listed among those that "link to" the template.

  • {{subst:Názov}} po uložení nahradí v zdrojovom texte stránky text obsahom šablóny. Kópia obsahu šablóny môže byť štandardne upravovaná a to oddelene od originálu na stránke šablóny. Poznámka: nepoužívajte tento spôsob, ak chcete kontinuálne distribuovať zmeny v obsahu šablóny na stránky, ktoré ju používajú.

That is, a copy of the contents of Template:Name will be substituted for the template call. No link is maintained between the page and the template, so each can be edited further without affecting the other. In effect, there is little difference between substituting the content in this way and simply typing it into the page's source "manually".

  • {{safesubst:Name}} — this was introduced to allow for recursive substitution in cases where templates contain calls to other templates or parser functions.

See Help:Substitution for more information.

  • {{msgnw:Názov}} vloží šablónu vo formáte, ktorý sa po načítaní zobrazí ako zdrojový kód (podobne, ako to robí <nowiki>).

In fact, an ordinary wiki page can also be used as a template, simply by specifying the namespace it resides in, so:

  • {{Template:Pagename}} transcludes the page titled Template:Pagename (equivalent to {{Pagename}})
  • {{Talk:Pagename}} transcludes the page titled Talk:Pagename
  • {{:Pagename}} transcludes the page titled Pagename (i.e., in the main namespace)
    • {{subst::Pagename}} substitutes the contents of the page titled Pagename

If the specfied namespace doesn't exist, the full title is assumed to be a template:

  • {{Foo:Bar}} transcludes Template:Foo:Bar

Použitie parametrov v šablónach

To enrich the mechanism of transclusion, MediaWiki allows parameters to be passed to a template when it is transcluded. Parameters allow the template to produce different contents or have different behaviors.

Suppose you wish to insert a little thank you note in the talk page of other users, such as:

Malé poďakovanie... za all your effort. Pozdravuje Me

The thank you note will have a reason (in this case, "all your effort") and a signature ("Me"). Your objective is that any user be able to thank any other user, for any reason whatsoever.

So that the note will look similar everywhere it is used, you can define a template called Template:Thankyou , for example. Although the note should look similar whenever a user thanks another user, its specific contents (i.e. the reason and the signature) will be different. For that reason, you should pass them as parameters. If we ignore the remaining elements to format the box and place the image, the core content of the template will be this:

'''A little thank you...'''
for {{{1}}}.
hugs, {{{2}}}

Notice the use of {{{1}}} and {{{2}}}. This is the way to identify, within templates, the parameters that will be passed in when the template is used. Note that, within the template, each parameter is surrounded by three braces: {{{ }}}. This is different from normal template name usage.

When using the template on a page, you fill in the parameter values, separated by a "pipe" character (|). MediaWiki allows parameters to be passed to the template in three ways: Anonymously, Numbered, and Named.

Anonymous parameters

To pass in anonymous parameters, list the values of those parameters sequentially:

{{Thankyou|all your effort|Me}}

In this case, the {{Thankyou}} template receives parameters {{{1}}}=all your effort and {{{2}}}=Me, producing:

Malé poďakovanie... za all your effort. Pozdravuje Me

The order in which anonymous parameters are passed in is crucial to its behavior. Reversing the order of the parameters, like so:

{{Thankyou|Me|all your effort}}

would produce this result:

Malé poďakovanie... za Me. Pozdravuje all your effort

Identifying parameters by order (with {{{1}}}, etc.) works only with anonymous parameters. Any parameters identified by name, as shown below, will not be accessible to the template using ordinal numbers.
If an equal sign appears inside the argument to an anonymous template parameter, that parameter may be misinterpreted as a named parameter (which is explained below in this document) treating the text before the equal sign as the parameter name and the text after it as the argument value. This is a common problem when you need to include an external link, or an HTML element with attributes (see task T16235). The workaround is to use named parameters instead, or even numbered parameters as explained in the following section.

Šablóny s číslovanými parametrami

To pass in parameters by number, identify each parameter when passing it:

{{Thankyou|2=Me|1=your friendship}}

This time, template {{Thankyou}} receives parameters {{{1}}}=your friendship and {{{2}}}=Me, though they have been supplied in inverse order, and produces:

Malé poďakovanie... za your friendship. Pozdravuje Me

This may also be useful when any of the numbered parameters contains an "=" sign.
<span lang="en" dir="ltr" class="mw-content-ltr">{{Thankyou|1=adding “=”|2=Me}}</span>


Malé poďakovanie... za adding “=”. Pozdravuje Me

Upozornenie Upozornenie: This also requires numbering each other parameter.

S pomenovanými parametrami

The third way of passing parameters is by name instead of numbers. In this case, the template contents would be changed to:

'''A little thank you...'''
for {{{reason}}}.
hugs, {{{signature}}}

Within the template, we use {{{reason}}} and {{{signature}}} to identify each parameter, instead of a number. To pass these parameters by name, identify each parameter when passing it:

{{Thankyou|signature=Me|reason=being who you are}}

In this case, template {{Thankyou}} receives parameters {{{reason}}}=being who you are and {{{signature}}}=Me and produces:

Malé poďakovanie... za being who you are. Pozdravuje Me

Named parameters are case-sensitive, so:

{{Thankyou|signature=Me|Reason=being who you are|reason=being case-sensitive}}


Malé poďakovanie... za being case-sensitive. Pozdravuje Me

The advantage of using named parameters in your template, besides also being flexible in the order parameters can be passed, is that it makes the template code much easier to understand if there are many parameters.

Default values

If you transclude a template that expects parameters, but do not provide their arguments, in this way:


in the numbered parameters example above you would get the following:

Malé poďakovanie... za {{{1}}}. Pozdravuje {{{2}}}

Since no arguments were passed in, the template presents the parameters themselves, instead of their respective values. In these cases, it may be useful to define default values for the parameters, i.e. values that will be used if no value is passed in. For example, if the template contents are changed to:

'''A little thank you...'''
for {{{reason|everything}}}.
hugs, {{{signature|Me}}}

then {{{reason|everything}}} defines that if no argument is provided for parameter {{{reason}}}, then the value everything will be used. Similarly, {{{signature|Me}}}, defaults parameter {{{signature}}} to value Me. Now, transcluding the template again without passing any argument results in the following:

Malé poďakovanie... za everything. Pozdravuje Me

The value of a parameter can be an empty string. For example, in {{foo|bar=}} or {{foo|bar=|baz=qux}}, the foo template considers the bar parameter to be "". This is different from omitting the parameter altogether, which leaves it undefined and triggers the default value mechanism described above.

Often default values are used to specify alternate names of parameters. For example, if you have {{{a|{{{b|}}} }}}, the template will first look for a parameter named "a". If it is not set, it will use the parameter named "b". If neither "a" nor "b" is set, it will output nothing.


This is an advanced topic which you can skip unless you need it.

Generally speaking, template parameters are substituted into the template after tokenization, but as is. They are not evaluated until they are used.

This has a few consequences. First of all, if you have a Template:Start containing {{mytemplate, and a Template:End containing |foo=bar}}, and put {{start}}{{end}} on a page, mytemplate isn't transcluded, because tokens like "|" cannot be added by a template and keep their special meaning in templates. You can still use templates to control the name of a parameter or template, but you cannot split a template call amongst multiple templates.

The second consequence of this is dead-code elimination. If you make a template call like {{foo|{{DISPLAYTITLE:Bar}} }}, and Template:Foo does not contain {{{1}}}, then the displaytitle is not used, since it is only evaluated when needed, and there is no parameter to substitute it into, so it is never evaluated. This usually comes into play when using Extension:ParserFunctions, and can be especially noticed when used in combination with the int: magic word that varies by user language.

Template calls starting with the magic word subst: or safesubst: are evaluated in a separate first pass that only happens at save time, along with ~~~~ and links using the pipe trick. If they cannot be evaluated during the first pass, subst: calls are ignored, and safesubst: are treated as if a normal template.

Many but not all parser functions, parser tags and trancluded special pages are not directly included like templates but instead are replaced by a "strip marker". This means you cannot manipulate the results with parser functions like padleft: or similar functions from extensions, as they see the strip marker instead of the result of the parser function.

Recursion in templates

Including a template in itself won't throw MediaWiki into infinite recursion. MediaWiki will stop the recursion with the template's name in bold. For example, if the content of Template:Aaaa is a {{Aaaa}} z, it'll display "a a Template loop detected: Template:Aaaa z z".

Forbidden idiom

This safeguard precludes a potentially useful template idiom where a template self-normalizes its own calling arguments. In this forbidden example template:d can either be called {{d|20200311}} or {{d|y=2020|m=3|d=11}}. If called in the first manner, it recurses into itself with the second argument structure (obtained using string parser functions), which then follows a unified processing path.

{{#if:{{{1|}}}|{{d|y={{#sub:{{{1}}}|0|4}}|m={{#sub:{{{1}}}|4|2}}|d={{#sub:{{{1}}}|6|2}}}}|<!-- processing path with arguments y,m,d regardless of original call pattern -->}}

If template:d is modified to recurse into template:d/2 and template:d/2 is an identical manual copy of template:d this idiom works fine as the self-recursion safeguard operates dynamically and not statically.

A feasible way for the MediaWiki software to loosen the self-recursion rule would be to require that each recursive call have a distinct argument count from all previous active calls, at most once recursing with the argument count non-decreasing. That would provide a strong guarantee against infinite self-recursion while enabling useful idioms such as the one described here in a flexible manner.

If the processing path is of low complexity, a simple solution using only one template is to handle each calling convention on a separate if/else branch, duplicating the logic of the processing path within each case. If the processing path is more complex, each call-structure case can delegate to an implementation template with a unified call structure which provides the final template behaviour.

Tables in parameters

Since the pipe character (|) and equality sign (=) have different meanings in template calls and wikitables, in order to use table markup in the value of a template parameter one generally needs to "escape" those characters (i.e., protect them from interpretation as template markup) using special sequences:

  • the built-in magic word {{!}} provides an "escaped" version of | since MediaWiki 1.24
  • the built-in magic word {{=}} provides an "escaped" version of = since MediaWiki 1.39

Before the introduction of these magic words, many wikis used templates to accomplish the same things. On such a wiki, the magic words take precendence over the same-named templates.

Example table

A1 B1 C1
A2 B2 C1

Table code:

{| class=wikitable

Escaped table code:

{{{!}} class{{=}}wikitable

Note that the first left-brace ({) is interpreted as a literal left-brace character because it is immediately followed by the {{!}} magic word. Similarly, the last right-brace (}) is interpreted as a literal right-brace character because it is immediately preceeded by the same magic word. However, in some cases these brace characters do cause problems, so some wikis provide templates for escaping these characters, as well:

  • the template call {{(}} might provide an "escaped" version of {
  • the template call {{(}} might provide an "escaped" version of {

Some wikis go even further and provide other convenience templates like {{(!}} and {{!!}}. On such a wiki, the code can be simplified a bit to this form:

{{(!}} class{{=}}wikitable

Ovplyvňovanie vkladania šablón

By default, a template's content is displayed in its entirety, both when viewed directly and when included in another page. However, Vkladanie šablón môžete ovplyvňovať pomocou značiek ‎<noinclude>, ‎<includeonly> a ‎<onlyinclude>.

Čokoľvek medzi ‎<noinclude> a ‎</noinclude> sa spracuje a zobrazí len v prípade, ak sa priamo zobrazuje stránka šablóny (nie stránka, do ktorej je šablóna vložená). Možné využitia sú:

Opakom je ‎<includeonly>. Text medzi ‎<includeonly> a ‎</includeonly> bude spracovaný a zobrazený len v prípade, ak je stránka vkladaná.

  • Jasným príkladom je pridanie všetkých stránok, ktoré obsahujú danú šablónu do kategórie bez toho, aby bola do kategórie pridaná samotná šablóna. Poznámka: keď zmeníte kategórie pridelené šablónou, kategorizácia stránok používajúcich šablónu sa môže vykonať až za nejaký čas: toto ovplyvňuje fronta úloh .
  • Ensuring that the template's code is not executed when viewing the template page itself. Typically this is because it expects parameters, and its execution without parameters has an undesired result.

Everything outside ‎<noinclude> and ‎<includeonly> is processed and displayed normally; that is, both when the template page is being viewed directly and when the template is included in another page. The focus is on what is inside these two tags.

Everything outside ‎<onlyinclude> tags is discarded in the transclusion. Even sections tagged includeonly are discarded in the transclusion unless they are also tagged as onlyinclude. The focus is on what is outside this tag.

Nesting of these tags is also possible.

The three partial transclusion tags enable all possible combinations of what is processed and rendered. Comments also fill a role.

Organizovanie šablón

Aby mohli byť šablóny využívané efektívne, musia ich byť schopní užívatelia ľahko nájsť a použiť. Jednoduchá technika je vloženie príkladu použitia šablóny priamo na stránku šablóny.

To find them, users can:

  1. Click Špeciálne stránky > Všetky stránky
  2. In the Menný priestor: list, choose Template and click Vykonať.


== Použitie ==
Umožní vytvoriť odkaz na subjekt:

Redaktor potom podobnú stránku vytvorí tak, že jednoducho príklad skopíruje.

While editing a page, a list of all templates used is available under the editing form, in a collapsible section titled "Templates used on this page:" (also named "Templates used in this preview:", or "Templates used in this section:" depending on the context). This list provides a convenient link to the template's page, as well as information about its protection status. Redirected templates are shown in italics, with the redirect target added as a separate list item.

Linking to a template

A template page can be linked to like any other wiki page. For example, the link Template:Navbar is generated using the wikicode [[Template:Navbar]].

On many wikis, Template:Tl can be used to provide a link to a template formatted in a way that shows the "double curly-braces" wikicode necessary to transclude the template without actually doing the tranclusion. For example, the code {{tl|Navbar}} may be used to create the link {{Navbar}}.

This construct is commonly used when referring to templates in template documentation, on help pages, and on talk pages. The same effect can be achieved by using {{[[Template:Navbar|Navbar]]}}, but the {{tl}} approach involves much less typing. On any given wiki the Tl template, if it exists, may or may not render the text in a "code" element or as monospace type. If not (as on this wiki), another similarly named template may do so. See, for example, the "See also" section of our Template:Tl documentation.

Copying from one wiki to another

Templates often require CSS or other templates, so users frequently have trouble copying templates from one wiki to another. The steps below should work for most templates.

MediaWiki code

If you have import rights (specifically importupload) on the new wiki:

  1. Go to Special:Export on the original wiki, and download an .xml file with the complete history of all necessary templates, as follows:
    • Enter the name of the template in the big text box, e.g. "Template:Welcome". Pay special attention to capitalization and special characters — if the template name isn't exactly correct, the export may still occur but the .xml file will not have the expected data.
    • Select the box "Vrátane šablón".
    • Select the box "Zahrň iba aktuálnu verziu, nie kompletnú históriu".
    • Click "Export".
  1. Go to Special:Import on the new wiki and upload the .xml file.

If you don't have import rights on the new wiki:

  1. Go to the template you want to copy from the original wiki. Go to the edit page, and copy all the wikitext
  2. On the new wiki, go to the page with the same name as the template you copied. Hit create/edit and paste the wikitext you copied. In the edit summary of each template, link to the original page for attribution.
  3. Back in the original wiki at the edit window, below the edit box, look at the list of "Templates used on this page". For each template listed follow these instructions. Also do that for any template used by any of these templates, and so on.

This will copy the entire code necessary, and will suffice for some templates. Note that only page elements parsed in rendering the page get exported, consequently documentation subpages are not exported as part of this process. If it doesn't work also check for red links listed under "Pages transcluded onto the current version of this page:", below the edit box. If there are any repeat the above steps for these as well and also copy the code in the modules.

After successfully importing the template and all its linked templates from the other wiki, edit it to change customisations to suit your wiki. For example to change a logo, remove redundant categories or red links.


An extension often used in templates is ParserFunctions. Visit page Extension:ParserFunctions and check if any of the functions listed there are used in the templates you've copied. If so, you have to install the ParserFunctions extension. To install it, you'll need system admin access to the server of your MediaWiki installation.

Another dependency that may be used in templates, especially those on Wikipedia, is Lua. Having {{#invoke: }} in template code is a good sign for it. In case it's used, you need to install the Scribunto extension and system admin access is required too. See that page for more instructions about installing and using the extension.

CSS and JavaScript code

Besides MediaWiki code, many templates make use of CSS and some rely on JavaScript to work fully. If the copied templates are not behaving as expected, this may be the cause. To copy the required CSS and JavaScript to your wiki you'll normally need to have admin privileges, because you'll be editing system messages in the "MediaWiki:" namespace.

  1. Look for the use of CSS classes (text like class="foobar") in the template text. If those classes appear in "MediaWiki:Common.css" or "MediaWiki:Monobook.css" on the original wiki, copy those classes to "MediaWiki:Common.css" on the new wiki and check if the template is now fine.
  1. If the copied template is still not working as expected, check if there is code in "MediaWiki:Common.js" or "MediaWiki:Monobook.js" on the original wiki. If so, you can try copying it to "MediaWiki:Common.js" on the new wiki. Normally, it is a good idea to only copy code from trusted sources, and first browsing the code to identify and select the parts that are relevant. You may find comments that can serve as clues to identify the functionality of each part.
