How can I publish text of a wiki-page in different languages depending on user's choice?


You can use multilanguage.phpΔ.


  • Every wiki page can hold different translations in the form:
    (:if userlang en:)
    english text
    (:if userlang it:)
    italian text
    common text
  • User selected language is stored in a cookie, can be selected with a "?userlang=xx" in the URL, if no language is selected and no cookie present the current language is detected from the browser.
  • If the selected language is not available/defined in the current page then a default language is displayed (from a cascade of preferred languages, the first available).
  • Different page titles can be defined inside each (:if userlang xx:) branch and the correct title will be available as {$Title} page variable. Also titled links [[Page|+]] will work correctly.
  • A (:selectlang:) directive will automatically display links (with the "?userlang=xx") for the languages that are defined on the page.



Download the script from above and place it in your cookbook directory. Then add include_once('cookbook/multilanguage.php'); in your local configuration (local/config.php).


Depending on which languages you will use in your wiki pages you will want to use the UTF8 features of PmWiki by adding include_once('scripts/xlpage-utf-8.php'); to your config.php before including the multilanguage.php.
Before including the multilanguage.php you may give a value to the following variables:
$DefaultLanguages is an array of preferred languages, it is used to display a default language if the selected one is not available in the page. The default is $DefaultLanguages = array('en');
ex. $DefaultLanguages = array('en','it','de');
If the user selected 'es' and in the current page only 'it' and 'de' are defined, then 'it' will be displayed.
$LanguageSelectionFmt can be used to personalize the output of the (:selectlang:) directive. Default is $LanguageSelectionFmt = '[[{$FullName}?userlang=$1|$1]] '; which will display links in the form: "en it de".
ex. $LanguageSelectionFmt = '[[{$FullName}?userlang=$1|Attach:$1.gif]] '; will display links with flags (provided you upload the flags images).
If you use translation pages (see: Internationalizations) you probably want to switch the XLPage definition too. To do this, use an if statement in your local configuration (config.php):
if ($_COOKIE['userlang'] == 'XX') {
Use PmWikiXX.XLPageLocal for your own phrases


The page content with multilanguage support can be defined including each language in a (:if userlang xx:) section.
(:if userlang en:)
english text
(:if userlang it:)
italian text
common text
The page variable {$userlang} holds the currently selected language (eg. "en").
You can put (:selectlang:) anywere in a page to display links to the available languages for that page.
The following parameters can be used:
page=... to specify the page for which display the links.
default=... to specify a default page for languages present in the $DefaultLanguages but who are not defined in the page (useful to direct the user to a homepage).
A new langinpage conditional is available, to test whether in a particular page a particular language is defined or not. The conditional takes two parameters, the language and the pagename.
(:if langinpage en MyGroup.MyPage:)
tests if in the page MyGroup.MyPage is defined the language "en".
(:pagelist if="langinpage {$userlang} {=$FullName}":)
lists all the pages in which is defined the language currently selected by the user.


Available languages and multilanguage page titles are parsed on edit and saved as page attributes to speed-up parsing on page load.
