Help:Templates/tl

Kung mayroon kang mga pamantayang tekstong nais mo maisama sa maraming mga pahina, narito ang tampo na MediaWika padron. Unlike extensions and media files, there is no central repository for templates. Templates can be newly written or to save duplicating work already done, exported from another wiki e.g. Wikipedia, and then imported into the target wiki.

Pagkakalikha
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 " ", assigning it to that namespace; besides this, you can create them like any other wiki page.

Ang pinakapayak na paggamit ng mga padron ay ang sumusunod. Kung lilikha ka ng isang pahinang tinatawag na ''Padron:Maligayang Pagdating" na may nilalaman:

Mabuhay! Maligayang pagdating sa wiki.

nailikha ang iyong kauna-unahang padron! Kung gayon, isingit ang kodigo:

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

You can then insert  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.

Pagkakagamit
Maaaring magamit ang mga padron o suloeras sa ibang pahina sa ganitong mga pamamaraan:


 * — as described above, this link will be dynamically replaced by the current content of Template:Name at the time the page with the template link is loaded. The link will remain unchanged in the page's source.
 * — when this template link is used, it will be replaced once and for all with the content of Template:Name as of the time the page with the link is saved: a copy of the contents of Template:Name will be substituted for the template link. The contents are then a part of the including page, and can be edited normally, separately from the original. Note: later changes to the source template page will not be propagated to the page with the template link.
 * — this was introduced to allow for substitution that doesn't break transclusion, see w:en:Help:Substitution.
 * includes the template in a form that displays it as raw wiki syntax (the way  does) when the page containing it is fetched.

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


 * includes
 * includes
 * includes
 * replaces itself with the contents of

If no such namespace exists, the full title is assumed to be a template:


 * includes

Mga Parametro
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:

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:

Bigyang-pansin ang paggamit ng  at. Ito ang paraan upang mabigyang-tukoy, sa loob ng mga padron o suleras, ang mga parametrong ihahanda kapag ginamit ang padron. Paalala lamang na, sa loob ng padron o suleras, napapaligiran ang bawat parametro ng tatlong tinatawag na braces:. Sadyang iba ito mula sa pangkaraniwang paggamit ng pangalang pang-padron.

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.

Mga di-kilalang parametro
To pass in anonymous parameters, list the values of those parameters sequentially:

In this case, the  template receives parameters   and , producing:

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

magbibigay ng resultang ito:

Note: Identifying parameters by order (with, etc) works only with anonymous parameters. Any parameters identified by name, as shown below, will not be accessible to the template using ordinal numbers.

Note: 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 16235). The workaround is to use named parameters instead, or even numbered parameters as explained in the following section.

Mga nilagyang-bilang na parametro
To pass in parameters by number, identify each parameter when passing it:

This time, template  receives parameters   and , though they have been supplied in inverse order, and produces:

Mga pinangalanang parametro
The third way of passing parameters is by name (Note: named parameters are case-sensitive), instead of numbers. In this case, the template contents would be changed to:

A little thank you... for. hugs,

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

In this case, template  receives parameters   and   and produces:

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

sa binigyang-bilang na mga parametro na naka-halimbawa sa bandang itaas ay makukuha mo ang sumusunod:

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:

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

Order of evaluation
Template parameters are fully evaluated before they are passed to the template. So if one of your parameters is a call to another template, what is actually passed is the expanded parameter.

becomes before it becomes:

In a few circumstances, this order of evaluation makes a difference from the alternative. (The alternative being to check the results of the template call to see if there are additional templates to be expanded.)

Una, ang pangalan ng padron o suleras ay maaaring palawigin pa nang sabay at katulad ng sa mga parametro.

Thus might expand to So that a template called  could display the thank you in the preferred language (however that was determined.)

Secondly, the template being called can't construct a template from pieces to be called later. A template that took the form would not work if was and was.

Thirdly, the parameter being passed is expanded only once, rather than every place the parameter is used in the template. This is more efficient on the mediawiki server.

Finally, the template being called can't stop the parameter from being expanded altogether. Even if a template only uses a parameter in some circumstances, it will always have been expanded before the call was made.

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 " ", it'll show as "Template:Aaaa".

Control template inclusion
By default, a template's content is displayed in its entirety, both when viewed directly and when included in another page. However, you can control which parts of a template will be seen and included by the use of the  and   tags.

Anything between  and   will be seen only when the template's page is being viewed directly, but not when it is included in another page. This is useful when you want to include text or code in a template that you do not want to propagate to any pages which include it, such as:


 * Category links when categorizing the template itself
 * interlanguage links to similar templates in other languages
 * Explanatory text about how to use the template

Likewise, anything between  and   will be processed and displayed only when the page is being included, but not when the template page is being viewed directly, and is useful in situations such as:


 * Categorizing pages which include the template. Note: when changing the categories applied by a template in this fashion, the categorization of the pages which include that template may not be updated until some time later: this is handled by the . To force the re-categorization of a particular page, open that page for editing and save it without changes.
 * 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  and   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  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.

Pagsasa-ayos ng mga padron o suleras
Upang maisa-epektibo ang mga padron o suleras, kailangang hanapin ang mga iyon ng mga tagagamit, at alamin kung paano gamitin ang mga iyon.

Upang hanapin ang mga iyon, ang mga tagagamit ay maaaring:
 * 1) I-klik ang ' > '
 * 2) Sa talaan ng ', piliin ang Padron at i-klik ang '.

To give usage information, include an example like this one on the template page:

Usage
Welcome users:

Then, an editor can simply copy and paste the example to use the template.

Pagsasa-kawing sa isang padron
To link to a template instead of including it, use the tl template. The name of the template the editor wants to link to goes after the vertical pipe. Halimbawa: links to the navbar template.

Pagkokopya mula sa isang wiki patungo sa iba
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:
 * 2) * 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.
 * 3) * Check the box "".
 * 4) * Uncheck the box "".
 * 5) * Click "".
 * 6) 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. 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.

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.

Extensions
An extension often used in templates is ParserFunctions. Visit page and check if any of the functions listed there are used in the templates you've copied. If so, you have to install the. 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  in template code is a good sign for it. In case it's used, you need to install the and system admin access is required too. See that page for more instructions about installing and using the extension.

CSS at kodigong JavaScript
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  ) 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.
 * 2) 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.
