TYPO3 loading object based on current front end language - typo3

Question

I'm running a Typo3 v9.5.4 Onepager style Website. The content is loaded directly from the tt_content. The Website has two FE languages (German/English).
I have a CTA button which has an anchorlink. The button is create with typoscript. I created one button for the German version and one for the English verson bc they have another value and another ancorlink.
I'm not sure if I can access a tt_content field directly from a fluid viewhelper. This is my code i've tried
<f:if condition="{tt_content.sys_language_uid} == 1">
<f:then>
<f:format.raw>{buttonEn}</f:format.raw>
</f:then>
<f:else>
<f:format.raw>{buttonDe}</f:format.raw>
</f:else>
</f:if>
This is my Typoscript for the two button Objects
lib.buttonDe = TEXT
lib.buttonDe {
value = German Text
stdWrap.typolink.parameter = #anchorlinkDE
stdWrap.typolink.ATagParams = class="button"
}
lib.buttonEn = TEXT
lib.buttonEn {
value = English Text
stdWrap.typolink.parameter = #anchorlinkEN
stdWrap.typolink.ATagParams = class="button"
}
And this is the typoscript that loads the Content, the Languages Menu and the Fluidtemplate (the Onepager Content is loaded without a Fluidtemplate, it loads the content directly from tt_content):
//--------------------- One Pager Content
lib.sectionContent = HMENU
lib.sectionContent {
excludeUidList = 12,13,16,17,29
1 = TMENU
1 {
NO = 1
NO {
doNotLinkIt = 1
stdWrap >
stdWrap {
cObject = COA
cObject {
if.value = 4
if.equals.field = doktype
if.negate = 1
10 < temp.titleSectionId
10.wrap = <section id="|">
20 = CONTENT
20 {
table = tt_content
select {
pidInList.field = uid
orderBy = colPos,sorting
# Only selects Content where CE Layout is 0
where = (tt_content.layout = "0")
}
wrap = <div class="container">|</div>
renderObj < tt_content
}
30 = TEXT
30 {
wrap = </section>
}
}
}
}
}
}
//---------------------
// Language Selector
lib.langmenu = HMENU
lib.langmenu {
special = language
addQueryString = 1
special.value = {$config.language.uids}
1 = TMENU
1 {
wrap = <ul class="dg-langmenu row">|</ul>
NO = 1
NO {
stdWrap.current = 1
stdWrap.setCurrent = {$config.language.labels}
allWrap = <li class="col s6">|</li>
}
ACT < .NO
ACT.doNotLinkIt = 1
ACT.allWrap = <li class="act col s6">|</li>
}
}
page = PAGE
page{
10 = FLUIDTEMPLATE
10 {
templateName = TEXT
templateName.stdWrap{
cObject = TEXT
cObject{
data = levelfield:-2,backend_layout_next_level,slide
override.field = backend_layout
split {
token = pagets__
1.current = 1
1.wrap = |
}
}
ifEmpty = onePager
}
templateRootPaths {
10 = {$path.privat}Templates/
}
layoutRootPaths {
10 = {$path.privat}Layouts/
}
partialRootPaths {
10 = {$path.privat}Partials/
}
variables{
buttonDe < lib.buttonDe
buttonEnd< lib.buttonEn
}
}
So I'd like to load the buttonEn if the content has the sys_language_uid 1 (English) else I want it to load the buttonDe.
Do I need to create an Typoscript Object and then load this Object into the f:if viewhelper? If so how do I create this Typoscript Object.
Thanks for your help!

Answer 1

The easy way (pure typoscript)
lib.button = TEXT
lib.button {
value = English text
lang.de = Deutscher Text
stdWrap.typolink.parameter = #anchorlinkDE
stdWrap.typolink.ATagParams = class="button"
}
[siteLanguage("locale") == "en_EN.UTF-8"]
lib.buton.stdWrap.typolink.parameter = #anchorlinkEN
[global]
but the professional solution is configuring your labels in a language file (see answer from Thomas Löffler) and use:
lib.button = TEXT
lib.button {
lib.button.data = LLL:EXT:site_extension/Resources/Private/Language/locallang.xlf:button_label
stdWrap.typolink.parameter = #anchorlinkEN
stdWrap.typolink.ATagParams = class="button"
}
[siteLanguage("locale") == "de_DE.UTF-8"]
lib.buton.stdWrap.typolink.parameter = #anchorlinkDE
[global]
For language dependent constant data you might use typoscript conditions to redefine a value for your non default languages. (or define a fallback and conditions for each language.)

Answer 2

You should use a locallang file and refer to it in TypoScript.
Create a locallang file (copy an existing and remove all values) named locallang.xlf
Add your english label in there
Create a locallang file in the same folder with prepending de. in the filename (de.locallang.xlf) and add the german label
Refer to it in the TypoScript by using lib.button.data = LLL:EXT:your_ext/path/to/locallang/locallang.xlf:buttonLabel, see https://docs.typo3.org/typo3cms/TyposcriptReference/DataTypes/Index.html#lll
This TS getText function gets the label depending on the set language ID automatically and you only need one TS for the button.
