TYPO3 Language Switch with FLUID

I've made a language menu (switch) for TYPO3 7.6 with Fluid only, no TypoScript. Just a Dropdown, see screenshot below. I also used the Ext:vhs, here's my code example:

{namespace v=FluidTYPO3\Vhs\ViewHelpers}
<ul id="languageMenu" class="dropdown menu" data-dropdown-menu>  
    <!-- german L:0 -->
    <f:if condition="{v:page.language()}==0">
        <li class="de">
            <f:link.page pageUid="{page.uid}" additionalParams="{L:0}">
                <f:image src="EXT:myext/Resources/Public/Icons/Flags/de.svg" width="18" height="14" alt="" />
                <f:translate key="LLL:EXT:myext/Resources/Private/Language/locallang.xlf:language.de" />
            </f:link.page>
            <ul class="menu languageSubMenu">
                <li class="en">
                    <f:link.page pageUid="{page.uid}" additionalParams="{L:1}">
                        <f:image src="EXT:myext/Resources/Public/Icons/Flags/gb.svg" width="18" height="14" alt="" />
                        <f:translate key="LLL:EXT:myext/Resources/Private/Language/locallang.xlf:language.en" />
                    </f:link.page>
                </li>
            </ul>
        </li>
    </f:if>


    <!-- english L:1 -->
    <f:if condition="{v:page.language()}==1">
        <li class="en">
            <f:link.page pageUid="{page.uid}" additionalParams="{L:1}">
                <f:image src="EXT:hellocode/Resources/Public/Icons/Flags/gb.svg" width="18" height="14"
                         alt="{f:translate(key: 'LLL:EXT:hellocode/Resources/Private/Language/locallang.xlf:language.en')}" />
                <f:translate key="LLL:EXT:myext/Resources/Private/Language/locallang.xlf:language.en" />
            </f:link.page>
            <ul class="menu languageSubMenu">
                <li class="de">
                    <f:link.page pageUid="{page.uid}" additionalParams="{L:0}">
                        <f:image src="EXT:myext/Resources/Public/Icons/Flags/de.svg" width="18" height="14" alt="" />
                        <f:translate key="LLL:EXT:myext/Resources/Private/Language/locallang.xlf:language.de" />
                    </f:link.page>
                </li>
            </ul>
        </li>
    </f:if>
</ul>

At the moment the language switch is always shown. If there's no page translation, I'll get an 404 Error. Of course, the missing page aren't exist. How can I hide my language switch, if there's no translation?

In past I used USERDEF1 with TypoScript, but I need a solution with Fluid. I also see there's a viewhelper v:condition.page.isLanguage but this isn't working for me or I don't know how?! Is it possible to do this with Fluid or vhs?

I would be grateful for any advice. Otherwise I have to write typoscript again ...

Solution

  • You don't need extension for that. The viewhelpers languageMenu is enough.

    Here the code I use, ok for accessibility, working with bootstrap 4 :

    <div class="navbar-nav mr-auto dropdown show">
            <v:page.languageMenu
              hideNotTranslated="1" 
              order="0,1,2,3" 
              layout="name" 
              defaultLanguageLabel="Français"
              defaultIsoFlag="fr"
              labelOverwrite="FR,EN,NL,ES"
              as="menu">
    
              <ul class="navbar-nav mr-auto">
                <f:for each="{menu}" as="langMenu">
                  <li class="nav-item>
                    <f:if condition="{langMenu.current}=1">
                        <f:link.page pageUid="{page.uid}"
                        id="dropdownMenuLink" 
                        class="dropdown-toggle nav-link lang px-3 flag-nav--{langMenu.flag}"
                        additionalAttributes="{data-toggle:'dropdown', aria-haspopup:'true', aria-expanded:'false'}"
                        lang="{f:if(condition: '{langMenu.current}=1', then: '{langMenu.flag}')}"
                        title="<f:switch expression='{langMenu.flag}'>
                                    <f:case value='fr'>français actif, changer de langue</f:case>
