TYPO3 排版如果基于站点语言的条件

Question

My typo3 version is 11.5.10. I have two footer images, one for German and one for English. I want to render different image for different language. I tried this way for German language.

[siteLanguage("locale") == "de_DE"]
   50 = COA
      50 {
        wrap = <div class="footer__item col-sm-6 col-md-3 img-custom">|</div>  
        stdWrap {
          typolink {
            parameter = {$myconstant.footer-logo-link-4}
            parameter.noTrimWrap = || _blank|
          }
        }

        50 = IMAGE
        50 {
          file = user_uploads/german-footer.png

          layoutKey = srcset
          layout.srcset {
            element = <img WIDTH###" SOURCECOLLECTION###" ###PARAMS### ###ALTPARAMS### ###SELFCLOSINGTAGSLASH###>              }
        }
      }
[end]

And for English language.

[siteLanguage("locale") == "en_US"]
   50 = COA
      50 {
            wrap = <div class="footer__item col-sm-6 col-md-3 img-custom">|</div>  
            stdWrap {
              typolink {
                parameter = {$myconstant.footer-logo-link-5}
                parameter.noTrimWrap = || _blank|
              }
            }

            50 = IMAGE
            50 {
              file = user_uploads/english-footer.png

              layoutKey = srcset
              layout.srcset {
                element = <img WIDTH###" SOURCECOLLECTION###" ###PARAMS### ###ALTPARAMS### ###SELFCLOSINGTAGSLASH###>              }
            }
          }
    [end]

In both language FE i get English-footer. I also tried Different function of siteLanguage like

1. siteLanguage("navigationTitle")
2. siteLanguage("locale")
3. siteLanguage("hreflang") etc..

What i am doing wrong? Thanks in advance!

I get the following error in Typoscript Object Browser

Errors and warnings Warning: Line 5696: Object Name String, "[siteLanguage" contains invalid character "[". Must be alphanumeric or one of: "_:-/." Show details

Answer 1

In general, you should avoid conditions whenever possible. Conditions are evil!

Conditions are checked for each and every page request - before any cached content is touched. extensive use of conditions will be a performance killer.

For more details, search for "typo3 condition performance"

Using TypoScript if

A better way would be using the if -function, which is cachable, in combination with getText siteLanguage .

page.10 = TEXT
page.10.data = siteLanguage:languageId
page.10.stdWrap.wrap = <p>siteLanguage:languageId=|</p>

page.20 = IMAGE
page.20 {
  if.value = 1
  if.equals.data = siteLanguage:languageId
  file = EXT:example/Resources/Public/typo3_package_de.png
}

page.30 = IMAGE
page.30 {
  if.value = 0
  if.equals.data = siteLanguage:languageId
  file = EXT:example/Resources/Public/typo3_package_en.png
}
