Multilingual portals


Each Intrexx portal can be created in multiple languages.

The language and region are represented by ISO-639 and ISO-3166 codes (e.g. en-us for English (United States of America) or en-gb for English (United Kingdom). These codes are the basis for controlling languages in portals.

Multilingual does not just mean presenting texts in a language-dependent manner, but also presenting number and date values in the respective country. Even colors can be interpreted differently depending on the culture. Graphics with lettering also get a language-dependent aspect. Even the question whether the user reads from left to right or vice versa can play a role.

There are therefore various details that need to be considered and implemented when creating a multilingual portal - regardless of which technology is used. You will find what you need to know for this here.

Language switch in the browser

The additional control "Language switch" from the "Design" module is used for switching the language in the browser. The languages, which should be selectable here, must be activated in the Regional settings.

To switch to another format, used to format the date according to the region, for example, the additional control Locale switch from the "Design" module is used. The formats, which should be selectable here, must be activated in the Regional settings.

Portal properties - Regional settings

In the portal properties, accessible via the Portal menu, you will find the "Regional settings". The portal can be configured for international use here.


Different formats for displaying date and number values are used across the world. To provide portal users with the option to use formats that correspond with their region, so-called formats can be defined.

Available locations

This list shows all of the formats that can be selected.

Selected locations

This list shows all of the formats that have been activated for this portal.

Select / Deselect formats

Use the arrow buttons to move the selected formats to the other list.

Default setting

Select which language should be used for the default setting in the drop-down list beneath the languages.

Edit formats for the selected location

Opens a dialog where the date and number format for the currently selected location can be edited.

Date format

Normal / Brief / Long

There are three options for displaying the date in the browser: "Normal", "Brief" and "Long". For defining the format, the pattern from the Java SimpleDateFormats can be used.


A preview of the formatted date will be shown in each of the example fields.

Weeks starts with

Time zone

A time zone can be assigned to the portal here. Usually, this is the time zone of the server or the company headquarters. If portal users work in different time zones, these time zones can be assigned to a user in the user properties in the Users module. The time zone specified in the portal properties will be used if a custom time zone is not defined for a user.

In Intrexx, every date value is stored in UTC Universal Time Coordinated (GMT Greenwich Mean Time) in the database. When the time is shown in the browser, the difference of the current time zone will be added or taken away from the UTC. The database obtains the time zone setting from the operating system. The time zone of the Intrexx Portal Server and the database should be identical as a general rule. If the database time zone and Intrexx time zone are different, this could result in deviations in the calculation of the local time.

Date values, e.g. date of birth, that should not be changed, should be stored as text information when in doubt and if required, processed with Velocity when it should be displayed (formatting).


Any number of languages can be activated for your portal.

Country-specific languages

With this setting, localized languages such as "German (Switzerland)" can be used. When you click on "OK", the internal global language constants will be adjusted and supplemented. Intrexx checks whether the parent language of the localized language is already in the portal, i.e. "German". If this is not the case, a check is made to see if another, localized version of the language is available in the portal, such as "German (Austria)". If this cannot be found either, the default portal language is used to create the new global language constants.

Available languages

This list shows all of the languages that can be selected.

Selected languages

This list shows all of the languages that have been activated for this portal.

Move the currently selected language from one list to the other.

Modify the order of the languages, e.g. for the Language switch drop-down list.

Default language

The default language is used if, for example, language data for element titles is missing for the selected language. The default language is entered automatically as the default language for a newly created user to begin with.

Global texts

In the global texts area, the default texts that appear in the portal can be modified in each of the portal languages.

Meta tags

With meta tags, information for web servers, browsers, and automatic search programs on the internet can be provided. Meta tags are HTML tags that describe the contents of an HTML page. Search engines will, with the help of meta tags, create entries in their databases or calculate weightings in a list of hits.

INTREXX GmbH assumes no liability for errors made while editing meta tags.

Defined meta tags

All of the portal's meta tags are listed here.

Remove meta tag

Removes the meta tag currently selected.

Move up / Move down

Modify the order that the meta tags are written to the HTML in.


The title is written in the "<title>" tag of each portal page.


Opens a dialog where the title can be edited in the portal languages. The multilingual title cannot be connected to global language constants in meta tags.

"Language" column

The activated portal languages are shown here.

"Value" column

Enter the corresponding term in each of the languages.

Add meta tag / Edit meta tag

Opens a dialog where a new meta tag can be created and existing meta tags can be edited.


You can select the most common meta tags here. You can also define custom meta tags simply by entering the name of your meta tag without selecting an existing meta tag.

Value (single language)

Values for single language meta tags, such as "Robots=nofollow", can be entered here.

Value (multi-language)

With this option, values can be entered in each of the portal languages.


Opens a dialog where the title can be edited in the portal languages. The multilingual title cannot be connected to global language constants in meta tags. Click "OK" to save changes and close the dialog again.

Layout mapping

For all layouts

The meta tag will be generated in all portal layouts with this option.

For mobile devices only

The meta tag will only be generated in pages which have been transformed for mobile devices.

For selected layouts only

The meta tag can be released for individual layouts here.

Available layouts

All layouts that can be selected are listed here.

Selected layouts

All layouts are listed here where the meta tag is entered.

Move the currently selected layout from one list to the other.

Modify the order of the layouts in the list.

Meanings of meta tags

  • Description

    The description may not exceed 200 characters. In the "Description" tag you will enter information about the company, product, people, or page contents.

  • Keywords

    Keywords consist of individual words or expressions and should be separated with commas. With these keywords, the contents of the page will be summarized and output in variations. Select some appropriate formulations that a user would search for on the internet in order to find a page of your portal.

  • Robots (Instructions for search engines)

    Here you will define how the page will be handled by robots, which index pages for search engines.

  • noindex

    Forbids the page from being indexed

  • index

    Request for the page to be indexed

  • follow

    Index page and follow links to additional pages

  • nofollow

    Do not index page, do not follow links

There are a large number of additional meta types of information that can be entered. For more information on the topic, please search for literature on the topic of web design or the Internet.

Global language constants

Every text element used by default in Intrexx is defined in the global language constants. Furthermore, you will find specific language constants for Intrexx Share. This helps you to administrate texts that appear in the portal often and in many applications centrally.


Enter a search term here. Simply enter the desired term to do so.



You can filter the list by constants that are used in JavaScript or Velocity.

Own / Standard

With this filter, you can decide whether your own constants, Intrexx standard constants or both should be shown.

Name column

Displays the name of the language constant.

Type column

The use of the constant is shown here.

Language column

In the following columns, the texts will be shown in the respective portal languages.

Filter languages

Click here if you want to show/hide a language column, e.g. "English", in the list.

Create a copy of the language constant

Creates a copy of the constant currently selected.


Deletes the currently selected constant created by you. Intrexx standard constants cannot be deleted.

Add new language constant / Edit language constant

Opens a dialog where a new language constant can be defined or an existing language constant marked in the list can be edited.


Provide the language constant with a name here. This name will be used later to address the constant in each scope. The name has to be unique. Only use capital letters and avoid using special characters and spaces. The name must start with a letter, followed by letters, numbers or _. Specifying a namespace is recommended to isolate your own constants from the Intrexx standard constants. This can be namespace referring to projects or customers.


Here, you can specify the scope of a language constant:

Constant is only available in JavaScript

The constant cannot be used as a title in applications or in Velocity. Use as few of these language constants as possible because JavaScript always needs to be transferred. Only use language constants in JavaScript for messages in custom check routines (alert(), prompt(), confirm() or Intrexx-Notifier) or for a dynamic output in view text fields. The portal language currently defined is always used in JavaScript. If the first key is not found, the fallback parameter will be searched for next, provided the fallback parameter has been defined. If the fallback parameter also does not deliver a result, "undefined" will be returned.

// Read application constant
ix.text.i18n.getByApp(p_strAppGuid, p_strKey, p_strKeyFallback);
// Read portal constant
ix.text.i18n.get(p_strKey, p_strKeyFallback);

Constant is evaluated as a Velocity expression

The constant is available in Velocity and the Groovy context but not in JavaScript. Constants available for all uses can also be used in Groovy. Only use constants in Velocity for labeling pages. This is the most common application area and should therefore be preferred. This also applies when they are used in Groovy. The language key is entered as the ISO language code (de, en etc.). When accessing application constants, the application's GUID must be specified as a parameter.

## Read portal constant 
##(Portal language is used as a criterion)

## Read portal constant with default language
$I18N.getByLang(p_strLang, p_strKey)

## Read application constant 
## (Application GUID and constant as parameter)
$I18N.getByApp(p_strAppGuid, p_strKey)

## Read application constant with default language
$I18N.getByAppByLang(p_strAppGuid, p_strLang, p_strKey)

## Example
$I18N.getByAppByLang('3E4..2AF', 'de', 'myKey')

Constant is available for all uses

Avoid this setting as much as possible. This type should only be selected if the language constant appears in both of the cases named above. Global constants can be used in Velocity as follows:


Application constants can be used as follows:

$I18N.getByApp(" APPGUID", " NAME")

In Groovy, multilingual text constants can be used to generate log entries or constructions, that, for example, are written back to data fields. The constants can also be implemented for the purpose of labeling when generating data exports via Groovy (e.g. XML files). The object "g_i18n" is available for this purpose, it is initialized with the context language. If the context is missing, the default portal language is used as the fallback.

// Read application constant
def app = g_i18n.application("APPLIKATIONS_GUID")

// Read application constant with default language
def appde = app.language("ISO_LANGUAGE_CODE")

// Read portal constant
def portalConst = g_i18n["PORTAL_LANGUAGE_CONSTANT"]

// Read portal constant with default language
def portalde = g_i18n.language("ISO_LANGUAGE_CODE")
def portalConst = portalde["PORTAL_LANGUAGE_CONSTANT"]

// Example: Read application constants explicitly in English
def app = g_i18n.application("3F2…E1A")
def appen = app.language("en")
def text1 = appen["CUSTOMER"]
// Example: Read application constant
def app = g_i18n.application("3F2…E1A")
def text2 = app["CUSTOMER"]
// Example: Reading portal constants explicitly in German
def portalde = g_i18n.language("de")
def text3 = portalde["CAL_WEEK"]

// Example: Read out portal constants
def text4 = g_i18n["CAL_WEEK"]


You can give the language constant a title for each of your different portal languages.

"Language" column

The portal languages are shown here.

"Title" column

The title corresponds to the value that the constant has - it will be displayed when the constant is used in the selected area. Enter the value of your choice here.

Naming rules for language constants

Name your language constants meaningfully so that their use is clear. Using different prefixes can make it easier to differentiate between the names.


Used for


General constants used in different place, e.g. for labelling elements on the page or for the page title


Label for buttons


Texts in tables such as for a notification if data records are available (TABLE_NODATA_) or a table title (TABLE_TITLE_)


Texts for labels and specifications in the system data group


Texts in messages via JavaScript


Texts in warning messages via JavaScript


Texts in error messages via JavaScript


Texts for describing notifications in confirm requests

The "MSG_ constants" are an exception because messages can contain a title and text (Notifier). These can be distinguished by using a suffix at the end of the constant name:


Used for


The message title


The message text

If language constants are used for list entries, all specifications for this element should be grouped together language constant list. Use a property after the prefix to group them together - such as the term "ACCESSTYPE". Each of the options "_ROLE, _GROUP" and "_USER" is then added afterwards accordingly.


There are no hard and fast rules for naming language constants because how the constant names are defined depends on the complexity of the application. The naming examples stated above should only serve as a possible approach.

Portal Manager language settings

You can access this dialog via the "Extras" menu / Options.

Language of the Portal Manager

The language of the Portal Manager can be defined here. The new setting will take effect when you restart the Portal Manager.

Display language of multilingual titles

The language multilingual titles are displayed here can be selected.

Language adjustment

When opening an application, process or layout, a check is performed as to whether every element has been provided with a title in each of the portal languages. If you have, for example, activated an additional portal language, titles will remain blank to begin with. Upon opening, a dialog will be displayed which allows you to transfer the titles from an existing portal language to the empty titles of the newly activated portal language.

The setting to activate a check for missing titles can be activated in the Extras menu / Options menu with the setting "Check for missing titles". This must be done for each module.

Find and translate element titles

In the "Applications", "Design" and "Processes" modules, you can search for items that do not yet have a title in one of the portal languages. Click here for more information.

Exporting and importing texts and language constants

In the modules Applications and Processes, the titles and names of all elements can be exported and imported via the main menu (e.g. Application menu / Export texts...). The function can be used to translate applications or processes into other languages.

Texts and constants can be exported in CSV, XLS or XML formats. When importing, the format XLSX is also allowed.

Export texts

Export - Storage location

Select an export file here. Allowed file formats are CSV, XLS and XML.

Exclude elements from export

If you activate this setting, you can click on "Elements excluded from export" in another dialog to specify the elements whose texts should not be exported.

In this list, elements will be managed that are considered to be irrelevant for the language export. These will not be included in the export file. To exclude an element from the export, enter its XML name here. By doing this, all of this element's texts will no be exported. However, you can also define which of the element's texts should not be exported (e.g. shapedtablebase:title - apart from titles, all of the textes from the object "shapedtablebase" will be exported). Multiple text types can be chained together with : (e.g. element:type:type[...]). The XML name of elements and the corresponding text types can be retrieved from an export file.

Add element

Adds an additional, empty row. Double-click on this row to enter the element's XML name into the list.

Remove element

Deletes the highlighted element from the list.

Reset to Intrexx default

Restores the list to its original state.

Click on "OK" to save the settings and close the dialog.

Export - CSV settings

Line breaks in texts are coded with <IXLB> in the CSV format.

Separator / Encoding

If you use a CSV file for the export, select the type of separator and the encoding here.


Only display languages used in the portal

This option will only display the languages that are used as portal languages in the "Available" list. Move the languages that should be handled in the translation to the "Selected" list by using the arrow button. The order can be adjusted using the vertical arrow buttons; this affects the order of the columns in the export file.

Reference language

If you're exporting to an XML or Excel file, a language can be selected here that will function as the basis for translation. This will be made obvious in the exported file.

Global language constants - Export

Global language constants can be imported and exported from Portal menu / Portal properties / Regional settings / Global texts / Global language constants.

When exporting language constants, you will find the same settings as for exporting texts, with two exceptions:

Export Intrexx standard constants

The Intrexx standard constants will be included in the export.

Write empty strings if no value is available

If texts are missing, e.g. a missing title in French, an empty string is written. This has the effect that the language attribute "French" is created for this title upon import, provided it is not already available for the title in the target. If the setting is not activated, the attribute will not be created in the XML.


Select the import file. The following formats are permitted for the import file: CSV, XLS, XLSX and XML. The remaining settings in this dialog correspond to the settings that were made when the export file was made.

Write empty strings if no value is available

If you import texts, you will also find the setting "Set empty strings for missing values" here. This controls whether missing texts are written to the XML as empty strings during import.

Example: In the import file, no text is defined in French for a label. If the setting is not activated during the import, then the label will also not get an attribute for French in the title element, provided that there was also no attribute before the import. If the setting is activated, the title element will get the attribute for French with an empty string as the value.

XML export format for language constants

The XML format for importing and exporting language constants collects every text constant together in the block <texts>. Every constant is defined via an <element>. The constant name is stated as the key, whereas the value of the "type" always needs to be "constant". Every constant is defined via an <element>. Each language variable is written as a <text>element under the <element>. As well as the ISO code, the availability ("ALL", "VELOCITY", "JAVASCRIPT") of the constant is also defined in the "language" parameter. Language texts defined directly in the controls, are identified in the <element> tag with the parameters "type" (object type) and "key" (control GUID).

Multilingual titles


Whenever you see the globe symbol for multilingual titles in the Portal Manager, you have the ability to define the title in multiple languages.

In applications, you will find a button to the right of the title field in the properties dialog of elements. Clicking on the small arrow to the right of this button opens a menu where you can select whether a static title or a title from a constant should be used for the element.

If you select "Title" here, the button will then display the globe icon to the left of the small arrow.

If you select "Title from constant", you will find an "A" on the button afterwards.

Static titles

Click on the globe icon to open a dialog where a static title can be entered in the configured portal languages.

The browser will then use the text entered here depending on the language setting in the portal properties. This also applies when the user switches the language.

Title from constant

Constants can be used for element titles in applications instead of static text. In the browser, the text entered for the constants is then used depending on the language setting in the portal properties. This also applies when the user switches the language. Information on how to create constants, edit them and define the multilingual text is available here:

If you have selected "Title from constant" in the properties dialog of elements, the drop-down list for the title will then work like a search.

Simply enter the constant name you're looking for and select the correct constant from the drop-down list.

Clicking on the "A" in the button to the right of the title drop-down list opens the "Global language constants" dialog where you can also search for constants and edit them directly.

Language switch in modules

You can switch the language in which the element titles in each of the modules in the Portal Manager are displayed using the globe symbol in the tool bar.

Portal menu

For applications, which are integrated into the menu structure, you can define that the application title should be used as the menu item. If the title is already defined in multiple languages, the values for each of the portal languages will be used. If the Use title of application setting is disabled, you need to define the title for the menu item in each of the portal languages. Multilingual titles can also be defined for all other objects such as menu folders, links or separators.

Click here for more information about the menu structure.


Because each portal layout is an assembly of various containers that, especially for barrier-free concepts, should be understood by screen readers, the containers also need to be provided with multilingual titles. Custom language constants cannot be used in the layout. Each of the elements in the layout uses correspondingly defined global language constants.

User settings

In the Users module, region-specific settings can be defined in the user properties.

The settings defined here for time zone, language, format and layout overrule the settings made in the Regional settings of the portal.


Language constants in applications In the Applications module, using language constants is not only a good idea for multilingual applications but all applications can benefit from the use of the constants. Because the same text appears in multiple locations, these can be modified much more easily via a central constant. INTREXX GmbH therefore recommends developing applications from scratch, based on application constants.

Language constants in applications

Constants can also be defined directly in applications, which are then only valid within the application, unlike the global language constants. Constants for applications can be added, edited and deleted via the Application menu / Manage language constants. All information about the settings in the "Mange language constants" dialog is available here.

Options - Language constants

The optional settings for language constants and titles are accessed from the main menu "Tools / Options / Applications / Language constants and titles".

Constant type upon creation

Here, you can define the constant type that should initially be assigned to new constants.

Initial title assignment

You can define which type of title elements will be given when they are created in the Application Designer.

Preallocate title field with default title

The title will be taken from the language constant "DEFAULT_CTRL_<Control type>". In the browser, the title will be shown in the current portal language. The title is also applied to data fields and data groups with this setting.

Preallocate title field with prefix pattern

When creating elements, automatically sets the title from constant option and enters the pattern defined here. This preset can also be supplemented by the constant name.

Leave title field initially blank and when the user leaves the dialog,

  • leave the field blank

    The title field is left blank when the user closes the dialog.

  • display a warning

    A corresponding notification will be displayed, if the title field is left blank when the dialog is closed.

  • provide a default title

    The title will be taken from the language constant "DEFAULT_CTRL_<Control type>" if the title field is left blank when the dialog is closed.

Multilingual element titles

You can find out how to provide elements with multilingual titles here.

Multilingual list entries

For the elements

you can select User-defined values as the source for the list in the element.

Clicking on "Edit" opens the dialog for editing the list entries.

Constants can also be used here instead of static values. Click on the arrow to the right of the globe icon. Click here for information on how to select a constant. The displayed value from the constant and the saved value must be identical in this case.

Multilingual data records

You can discover how to enter data records in different languages and then display them correctly based on the respective portal language setting in the Tips & Tricks article "Multilingual data records".

Multilingual data with doubled primary key

In order to make data available in multiple languages, these can be saved in a data group using the principle of a doubled primary key. This is made up of a key and an ISO language code. For control tables, e.g. for statuses, the key should be a descriptive string. For all other data, it should be a GUID.

For the second primary key, a new data field titled "Language" is created before publishing the application.

On the "Expert" tab, the expert attribute "primarykey" is set to yes.

When data records are entered, both primary keys need to be populated with values so that errors do not occur when the data is processed. To do this, the language data field can be connected to an edit field in the hidden area. The input field is preallocated with the current portal language via its binding.

A common scenario for this is using multilingual master data, such as statuses, categories, in moving data records via a reference. If a reference to a data group with two primary keys is created, the session variable "Language" must be assigned for the primary key. The other primary key will be left with the setting "Will be created automatically".

Using the reference, Intrexx will now always provide the corresponding language text in the browser.

Multilingual emails

Email to one recipient

If a user sends an email, their language setting can be identified in a process. The process can use the identified language in an email sent with an Email action.

The subject can be defined by translating the language-dependent subject accordingly. In the properties dialog of the email action, the parameter "language" can be added on the Expert tab.

// Language of the current user
def l_strLanguage = Locale.forLanguageTag(g_language).getDisplayLanguage(new Locale(g_language))

// Language of any user 
// (via its GUID and the user object)
def l_objUser = g_om.getUser(l_strUserGuid)
def l_strLanguage = objUser.getDefaultLanguage()

// Putting language into the processing context
g_sharedState.maillanguage = strLanguage

In the properties dialog of the email action, the parameter "language" can be added on the "Expert" tab and the language determined from the processing context can be transferred as a value with "urn.sharedState.maillanguage".

The subject can also be defined using a language constant. With the corresponding Groovy method, the language constant's content is read based on the language identified in the previous step.

// Determine subject from language constant and place in processing context 

g_sharedState.subject = g_i18n.application("APP_GUID").language(l_strLanguage)["MYMAILSUBJECT"]

The value from the processing context is then entered in the static, language-independent subject of the email action with "urn.sharedState.subject".

If the email is sent via CC and BCC to one recipient with different languages in each case, this method cannot be used. This would require separate handling with an individual email action in each case in the process chain. The message text could also be identified in a preceding Groovy action and then written to the processing context. The processing context can then be read in Velocity and from that, the email body can be generated.

Email to distribution list

There are two approaches to sending emails to a distribution list if these should be sent multilingually:

  • An email action is created for each language where the recipients are selected based on their defined language.

  • The email is generated with Groovy script while taking the language of each user into account. However, the message body needs to be constructed manually in this case.

A possible construction is shown below. In this case, however, only user objects can be recipients via the distribution list.

import de.uplanet.lucy.util.TextUtil
import de.uplanet.lucy.server.mail.GroovyMailBuilder
import de.uplanet.lucy.server.mail.MailUtil
import de.uplanet.lucy.server.portalserver.PortalServerPath
import de.uplanet.lucy.server.composer.UrlBuilder

// Contents of a distribution list (GUIDs of recipients)
def l_strRecipients = g_record["640...DAC"].value
def l_aReceipients = TextUtil.stringToList(strRecipients)

aReceipients.each {
  def strEmail = g_dbQuery.executeAndGetScalarStringValue(conn, "SELECT
    setString(1, it)
  if(strEmail != null && strEmail != "")
    def mail = new GroovyMailBuilder().composeMail {
	  headers = [
		"X-IX-Share": "intrexx-share-notification",

	from        = MailUtil.getDefaultSenderAddress()
	to          = strEmail
	subject     = l_mailHelper.getMailTitle()
	contentType = "text/html; charset=UTF-8"

	body << """<html>  … </html>"""

Language switches

To a large extent, you can avoid using language switches in programming codes with language constants. However, the following constructs could be useful in special cases. To create a language switch in JavaScript, the selected portal language needs to be identified with the "oHtmlRoot" object.

var l_lang = oHtmlRoot.oUp.oFormatInfo.lang;

  case "de":
       // Code for german language
  case "en":
       // Code for english language

       // Fallback if language is missing (default language of the portal)

if(l_lang == "de")
  // Code for german language
else if(l_lang == "en")
  // Code for english language


  // Fallback if language is missing (default language of the portal)

The "oHtmlRoot" object can also be used to identify the defined default language.

var l_defaultLang = oHtmlRoot.oUp.oFormatInfo.defaultLang;

Um im Velocity-Kontext sprachabhängige Weichen zu konstruieren, kann die Intrexx-Systemvariable $lang verwendet werden, die die aktuell eingestellte Portalsprache enthält.

#if($lang == "de")
  // Language dependent code
#elseif($lang == "en")
  // Language dependent code
  // Fallback in case of missing language

Different options are available for generating multilingual data in a Groovy script or to control certain actions based on the language.

// Current portal language
// Default language of the portal
// Current portal language via request parameter rq_Lang 
// Default language Users from the current session

A language switch can be created for various purposes using a switch case construction.

  case "de":
    return german
  case "en":
    return english
    return english

Multilingual graphics

If graphics are managed via data groups, these can be defined for each language-dependent data record. It is much more difficult to display language-dependent graphics in the layout, as this is not provided for technically. One option for this is to provide the graphic with the ISO code in the filename and then to construct the URL with Velocity using the current portal language. The following ActionControl generated a DIV container with a link to the portal homepage as well as the language-dependent embedding of a graphic. It is important to name the graphic with "logo_<iso-languagecode>.png". The control assembles the filename dynamically by using the current portal language "$lang".

<div id="Container_Logo">
	<a title="Home" href="/$Portal.getPortalName()">
		<img width="199" height="49" src="images/${layout}/logo_${lang}.png" alt="Home">

Velocity variables in language constants

In every language constant with the type "Constant is evaluated as a Velocity expression", Velocity variables can be embedded when these are used on application pages. For this to work correctly, the variable needs to be available in the page context. In the following example, the variable "$Rooms" is written into the text to add a dynamic statement - the number of rooms - to the static text.

Constant text:

There are $Rooms Room/Rooms in this building!

Output:There are 10 room/rooms in this building!

Language switch with flags

A language switch with flags only makes sense for a few portal languages, and only in combination with the language name. For languages such as English, that are represented by multiple countries and therefore flags, a language switch with flags is not always ideal. Intrexx already delivers a set of graphics with flags that possess the ISO code as their name. To begin with, add a new file called "languageswitch_flag.vm" to the portal directory \internal\system\vm\html\actioncontrol and copy the Velocity code below into this file.

#set($l_aAllLang = $WebMenu.getMenuLanguages())
<span id="ID_Languageswitch">#foreach($l_strLang in $l_aAllLang)
	#set($l_strImagePath = "images/assets/flags_of_the_world/16x16/plain/${l_strLang}.png")
	#set($l_strDisplayLang = $TextUtil.getDisplayLanguage($l_strLang, $l_strLang))
 	<a style="width: 16px; height: 16px; display: inline-block; background-repeat: no-repeat; background-position: center; background-image: url($l_strImagePath); cursor: pointer;" onclick="var oLangAction=setLangAction('$velocityCount', '$!l_strLang');oLangAction.changeLang();return false;" lang="$!l_strLang" target="_top" href="$Request.get('DEFAULT_URL')?rq_Lang=$!l_strLang" id="ID_actionLangSwitch${velocityCount}" title="$I18N.get('LANGUAGESWITCH_DESCRIPTION')"></a>#end
<script type="text/javascript">
	function setLangAction(count, lang){oLangAction = new upTextActionControl();oLangAction = oLangAction.biDirectUpHtml(oLangAction, 'ID_actionLangSwitch' + count);oLangAction.linkType = '4';oLangAction.oTarget = new upTarget();oLangAction.oTarget.rq_Lang = lang;return oLangAction;}

In the file "controls.xml", add the following block to the XML structure:

<control id="Action_LanguageSwitchFlag" mobile="false" multipleUse="false" vm="languageswitch_flag.vm">
	<title lang="en" value="Language Switch with Flags"/>
	<title lang="de" value="Sprachumschalter mit Flaggen"/>
	<description lang="en" value="Language Switch"/>  
	<description lang="de" value="Sprachumschalter"/>

After restarting the Portal Manager, the additional control can be selected accordingly and added to the layout.
