=======================================================================

Breaking: #108148 - CDATA sections in Fluid templates no longer removed
|
|
=======================================================================
|
|
|
|
See :issue:`108148`
|
|
|
|
Description
|
|
===========
|
|
|
|
Previous versions of Fluid and TYPO3 removed code wrapped in `<![CDATA[ ]]>`
|
|
from template files altogether. This meant that it was possible to use CDATA
|
|
to comment out template code. This is no longer possible, since CDATA
|
|
sections are now interpreted by Fluid in a different way; see
|
|
`Feature: #108148 - Alternative Fluid Syntax for CDATA Sections <https://docs.typo3.org/permalink/changelog:feature-108148-1763288461>`_.
|
|
|
|
Impact
|
|
======
|
|
|
|
`<![CDATA[ ]]>` can no longer be used to comment out code in Fluid template
|
|
files.
|
|
|
|
Affected installations
|
|
======================
|
|
|
|
Installations that contain Fluid templates using `<![CDATA[ ]]>` to comment
|
|
out code are affected. A deprecation has been written to the deprecation log
|
|
since TYPO3 13.4.21 if this construct is encountered in a Fluid template
|
|
during rendering.
|
|
|
|
Migration
|
|
=========
|
|
|
|
To comment out code in Fluid templates, the
|
|
`Comment ViewHelper <f:comment> <https://docs.typo3.org/permalink/t3viewhelper:typo3fluid-fluid-comment>`_
|
|
should be used. Since TYPO3 v13, potential Fluid syntax errors are ignored by
|
|
this ViewHelper, which allows commenting out invalid Fluid syntax safely.
