Breaking: #80412 - New shared content element TypoScript library object for Fluid Styled Content

Description

To solve an inconsistency issue for API based content element registration between CSS Styled Content (CSC) and Fluid Styled Content (FSC) through Extbase or addPItoST43 we are now introducing a new shared content object for content elements and drop the active usage of lib.fluidContent.

The generated code relied on the existence of the removed lib.stdheader and also ignored layouts, frames, spacebefore, spaceafter in context of Fluid Styled Content.

For content element registration the TypoScript lib.contentElement is now used for CSC and FSC and replaces the usage of lib.fluidContent. The generated code was slightly adjusted to match the requirements of all content rendering definitions and can be adapted to the specific needs of a content element rendering definition anytime since a reference is used now instead of a hard definition.

Generated code before change

tt_content.myce = COA
tt_content.myce {
   10 =< lib.stdheader
   20 =< plugin.myContent
}

Generated code after change

tt_content.myce =< lib.contentElement
tt_content.myce {
   templateName = Generic
   20 =< plugin.myContent
}

CSS Styled Content

CSS Styled Content adds the missing lib.stdheader and everything works as before, no migration or adjustments to your code necessary. Because COA does not understand the option templateName it will simply be ignored.

lib.contentElement = COA
lib.contentElement {
   10 =< lib.stdheader
}

Fluid Styled Content

Fluid Styled Content adds the logic it needs through lib.contentElement. All content elements registered through the TYPO3 APIs will now share a multifunctional Generic template. That will provide the necessary layouts and overriding options known from FSC.

lib.contentElement = FLUIDTEMPLATE
lib.contentElement {
   templateRootPaths {
      0 = EXT:fluid_styled_content/Resources/Private/Templates/
      10 = {$styles.templates.templateRootPath}
   }
   partialRootPaths {
      0 = EXT:fluid_styled_content/Resources/Private/Partials/
      10 = {$styles.templates.partialRootPath}
   }
   layoutRootPaths {
      0 = EXT:fluid_styled_content/Resources/Private/Layouts/
      10 = {$styles.templates.layoutRootPath}
   }
   ...
}

<html xmlns:f="http://typo3.org/ns/TYPO3/CMS/Fluid/ViewHelpers" data-namespace-typo3-fluid="true">
<f:layout name="Default" />
<f:section name="Main">

   <f:comment>This templates is used to provide necessary functionality for external processed content and could be used across multiple sources, for example the frontend login content element.</f:comment>
   <f:if condition="{content}">
      <f:then>{content -> f:format.raw()}</f:then>
      <f:else><f:cObject typoscriptObjectPath="tt_content.{data.CType}.20" data="{data}" table="tt_content" /></f:else>
   </f:if>

</f:section>
</html>

The TypoScript object lib.fluidContent will be kept as copy of lib.contentElement for compatibility for the duration of TYPO3 v8 LTS and will be removed in TYPO3 v9.

Impact

Assignments and overrides made directly to lib.fluidContent are not recognized anymore for core content elements provided by Fluid Styled Content. They need to be migrated to lib.contentElement. Only not modified versions of lib.fluidContent will keep working as expected.

Affected Installations

Installations that directly modify lib.fluidContent.

Migration

Rename assignments and modifications to lib.contentElement.
