Using Site Configuration in TypoScript

getText

Site configuration can be accessed via the site property in TypoScript.

Example:

page.10 = TEXT
page.10.data = site:base
page.10.wrap = This is your base URL: |

Where site is the keyword for accessing an aspect, and the following parts are the configuration key(s) to access.

data = site:customConfigKey.nested.value

To access the current siteLanguage use the siteLanguage prefix:

page.10 = TEXT
page.10.data = siteLanguage:navigationTitle
page.10.wrap = This is the title of the current site language: |

page.10 = TEXT
page.10.dataWrap = The current site language direction is {siteLanguage:direction}

ちなみに

Accessing site configuration is possible in TypoScript, which enables to store site specific configuration options in one central place (the site configuration) and allows usage of that configuration from different contexts. While this sounds similar to using TypoScript, with using site configuration this may also be used from backend or CLI context as long as the rootPageId of the site is known. To avoid duplicating configuration options, TypoScript can now access these properties, too.

Site configuration can also be used in TypoScript conditions.

FLUIDTEMPLATE

You can use the SiteProcessor in the The FLUIDTEMPLATE content object to fetch data from the site entity:

tt_content.mycontent.20 = FLUIDTEMPLATE
tt_content.mycontent.20 {
    file = EXT:myextension/Resources/Private/Templates/ContentObjects/MyContent.html

    dataProcessing.10 = TYPO3\CMS\Frontend\DataProcessing\SiteProcessor
    dataProcessing.10 {
        as = site
    }
}

In the Fluid template the properties of the site entity can be accessed with:

<p>{site.rootPageId}</p>
<p>{site.someCustomConfiguration}</p>
