Multi-language content filter: diferència entre les revisions

Revisió de 21:26, 5 gen 2013

The Multi-language content filter enables resources to be created in multiple languages. When turned on, it looks for <span lang="xx" class="multilang"> tags which indicate that a text contains multiple languages. Then it selects and outputs the best language for the current user. The language of the resource will change when the user changes their selected Moodle language.

How to use in a course

To use this feature first create your contents in multiple languages (in the same resource). Then enclose each language block (aka multilang block) in the following tags:

      <span lang="XX" class="multilang">your_content_here</span>
      <span lang="YY" class="multilang">your_content_in_other_language_here</span>

It is essential to be in the code editing mode (press [<>] in the HTML editor), when you enter these tags for them to work. Only spaces, tabs and enters can be used between the individual languages in the multilang block.

How it works internally

Filter first looks for multilang blocks in the text
For each multilang block:
- If there are texts in the currently active language, print them
- Else, if there exists texts in the current parent language, print them
- Else, print the first language found in the text
Text outside of multilang blocks will be shown always

Common problems

The multilang filter is not enabled. It can be enabled by a site administrator in Settings > Site administration > Plugins > Filters > Manage filters.
Extra characters between language span tags - editor might add <br /> or other tags, please review the html in source view
If the course setting is "force" some language, you won't be able to change the displayed language.
Extra spaces in language span tag
Can not easily access language choice dropdown! Unfortunately you must go to the site homepage or your own profile to change the displayed language. It is possible to manually quickly change displayed lang by editing the URL in the browsers address bar. See Tips and tricks below!

Tips and tricks

Changing language displayed without going to front page

It is possible to change the displayed language by manually changing the link.

Here is the default language page at id=2306. This link is in English, the default language:

http://moodle.org/mod/resource/view.php?id=2306

The link to change the page display to Spanish is

http://moodle.org/mod/resource/view.php?id=2306&lang=es ,

When the default language is an other language, to change the page to an English version, the link would be:

http://moodle.org/mod/resource/view.php?id=2306&lang=en

Thus, with a bit of editing, you can manually change the displayed language by adding "&lang=xx" to the URL in the location bar of the browser. Where xx is the abbreviation for the language you want.

-From which this is copied (and ought to be shortened):
- <nowiki>
- ... how the multilang filter works:
-) First of all it looks for multilang Blocks.
+[[es:Contenido multilingüe]]
-One Multilang block of text is defined as one group of <span lang="XX">
+[[fr:Contenu multilingue]]
-tags together, without anything between them.
+[[ja:多言語シンタックス]]
-) After this detection of Blocks, for each of them, Moodle selects
-the best language for the user displaying the info, showing its info
-and discarding the rest of lang tags in the block.
- So, applying this behaviour to the example you wrote above, we have:
-) Moodle looks for Blocks and it finds TWO blocks:
-Block A: <span lang="de">von links</span>
-Block B:<span lang="en"><span="en"><font size="3"> </font></span>from the left</span>
-) For each block, Moodle display the better language. As Both blocks
-only contain ONE lang tag, it's returned, so results are:
-For Block A: von links
-For Block B: <span="en"><font size="3"> </font></span>from the left
-Then obviously, in one web page, those results are showed as:
-von links
-from the left
-The key concept here is the Block of lang. Once you get it, everything is easily to understand.
-Also note that the HTMLEditor seems to introduce an excess of "noisy" tags
- under some circumstances and, if it does so between lang tags, it will be,
-in fact, breaking your blocks of langs! It's always recommended to check the
-final HTML generated by the HTML Editor in order to verify that the lang tags
-(and their grouping together is conforming blocks of langs) are properly
- written.</nowiki>
-If I were to want to translate a word or phrase to a chosen language in an English text:
- <nowiki>If I want to include an explanation <span lang="en"> </span>
- <span lang="sv">(sv: förklaring)</span> in a running text can I do it?
-<br />
-<br /><span lang="en">If I want to include an explanation in a running text
- can I do it? </span>
-<span lang="sv">If I want to include an explanation (sv: förklaring) in a
-running text can I do it?</span></nowiki>
-would both work, but not:
- <nowiki>If I want to include an explanation <span lang="en"></span>
- <span lang="sv">(sv: förklaring)</span> in a running text can I do it?
-<br />If I want to include an explanation <span lang="sv">(sv: förklaring)</span>
- in a running text can I do it?<br /></nowiki>
-which would show the Swedish even if English was the chosen language. NOTE the "span lang=en" must contain something, at least a space.
