多言語コンテンツフィルタでは、多言語のリソースを作成することができます。有効にした場合、テキストが多言語を含んでいることを意味する <span lang="xx" class="multilang"> タグが探されます。そして、現在のユーザに対する最適な言語が選択され、リソースが表示されます。The language of the resource will change when the user changes their selected Moodle language.

The multilang syntax was changed in 1.8. <lang> is not supported any more. It is required to add class="multilang" into each <span> tag in multilang block. The new syntax is backwards compatible with old plugins, which means it can be used in older Moodle version.

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. Please note that class="multilang" is not required prior to 1.8.

Following code

      <lang="XX">your_content_here</lang>
      <lang="YY">your_content_in_other_language_here</lang>

does NOT work.

The obsoleted HTML tagging

      <lang lang="XX">your_content_here</lang>
      <lang lang="YY">your_content_in_other_language_here</lang>

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

will not work in 1.8 and later. In 1.8 the lang attribute without class="multilang" can be used to mark the language of the text - see http://www.w3.org/TR/html4/struct/dirlang.html

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

Course summary and title tags

To be able to change text such as resource titles and summaries, an administrator must choose Filter all strings in the site administration.

 <span lang="en" class="multilang">Matematically</span> <span lang="sv" class="multilang">Matematiskt (svenska)</span>

functions as English or Swedish title.

It doesn't seem to work for course titles (neither long nor short version).

In the course summary:

<span lang="en" class="multilang">Growth is often a major concern in planning society.
 How can one avoid superficial conclusions? <br>
(Exists in Swedish too. Finns på svenska också)</span>
 <span lang="sv" class="multilang">Tillväxt är ofta använt i samhällsdebatten. 
Hur kan man undvika ytliga slutsatser? 
 (Finns på engelska också. Exists in English too.)
<br /></span>

Can show in the chosen language (and point out that the other language is there). Please note that class="multilang" is not required prior to Moodle 1.8.

Translations with tags

If you wish to translate a word or phrase in an English text to another language:

If I want to include an explanation <span lang="en"> </span>
 <span lang="sv" class="multilang">(sv: förklaring)</span> in a running text can I do it?
<br />
<br /><span lang="en" class="multilang>If I want to include an explanation in a running text
 can I do it? </span>
<span lang="sv" class="multilang>If I want to include an explanation (sv: förklaring) in a 
running text can I do it?</span>

would both work, but not:

If I want to include an explanation <span lang="en" class="multilang></span>
 <span lang="sv" class="multilang>(sv: förklaring)</span> in a running text can I do it?
<br />If I want to include an explanation <span lang="sv" class="multilang>(sv: förklaring)</span>
 in a running text can I do it?<br />

which would show the Swedish even if English was the chosen language. NOTE that before 1.8 the "span lang=en" must contain something, at least a space.

New multilang syntax

Moodle 1.8

<span lang="xx"> and <lang> should not be used anymore
Existing content can be upgraded using the admin/multilangupgrade.php script, there is a link in the admin notification page if a multilang upgrade is required.
The multilang filter can be configured to use old syntax only - see Multi-Language Content Settings; this setting may be removed in 1.9
New syntax is forced during a new 1.8 installation, for upgraded sites the new syntax is enabled after the multilang upgrade

Common problems

The multilang filter is not enabled - go to filter settings and enable it
Filter all strings not enabled on sites that need multilang in titles, navigation, headings, etc.
Extra characters between language span tags - editor might add <br /> or other tags, please review the html in source view
Extra spaces in language span tag
