LanguageMenuProcessor¶

This menu processor generates a list of language menu items which can be assigned to the FLUIDTEMPLATE as a variable.

Hint

The third-party extension b13/menus also provides a language menu processor: B13\Menus\DataProcessing\LanguageMenu.

Refer to the manual of the extension b13/menus for more information.

Options:¶

if¶

Required: false
Type: if condition

Only if the condition is met the data processor is executed.

languages¶

Required: true
Type: string, stdWrap
Default: "auto"
Example: "0,1,2"

A list of comma-separated language IDs (e.g. 0,1,2) to use for the menu creation or auto to load from the site configuration.

addQueryString.exclude¶

Required: true
Type: string, stdWrap
Default: ""
Example: "gclid,contrast"

A list of comma-separated parameter names to be excluded from the language menu URLs.

as¶

Required: false
Type: string
Default: defaults to the fieldName

The variable name to be used in the Fluid template.

Example: Menu of all language from site configuration¶

Please see also About the examples.

TypoScript¶

Using the LanguageMenuProcessor the following scenario is possible:

EXT:examples/Configuration/TypoScript/DataProcessors/Processors/LanguageMenuProcessor.typoscript¶

tt_content {
    examples_dataproclang =< lib.contentElement
    examples_dataproclang {
        templateName = DataProcLangMenu
        # Before TYPO3 v12.1 you have to specify the fully-qualified class name of the processor
        # dataProcessing.10 = TYPO3\CMS\Frontend\DataProcessing\LanguageMenuProcessor
        # Since TYPO3 v12.1 one can also use the available alias
        dataProcessing.10 = language-menu
        dataProcessing.10 {
            languages = auto
            as = languageNavigation
        }
    }
}

New in version 12.1: One can use the alias language-menu instead of the fully-qualified class name \TYPO3\CMS\Frontend\DataProcessing\LanguageMenuProcessor.

The Fluid template¶

This generated menu can be used in Fluid like this:

EXT:examples/Resources/Private/Templates/ContentElements/DataProcLangMenu.html¶

<html data-namespace-typo3-fluid="true" xmlns:f="http://typo3.org/ns/TYPO3/CMS/Fluid/ViewHelpers">
   <h2>Data in variable languageNavigation</h2>
   <f:debug inline="true">{languageNavigation}</f:debug>

   <h2>Output</h2>
   <f:if condition="{languageNavigation}">
      <ul id="language" class="language-menu">
         <f:for each="{languageNavigation}" as="item">
            <li class="{f:if(condition: item.active, then: 'active')}
                    {f:if(condition: item.available, else: ' text-muted')}">
               <f:if condition="{item.available}">
                  <f:then>
                     <a href="{item.link}" hreflang="{item.hreflang}"
                        title="{item.navigationTitle}">
                        <span>{item.navigationTitle}</span>
                     </a>
                  </f:then>
                  <f:else>
                     <span>{item.navigationTitle}</span>
                  </f:else>
               </f:if>
            </li>
         </f:for>
      </ul>
   </f:if>

</html>

Output¶

The array now contains information on all languages as defined in the site configuration. As the current page is not translated into German, the German language has the item.available set to false. It therefore does not get linked in the template.
