Breaking: #67811 - Rte API

See Issue #67811


The RTE implementation was based on the main classes \TYPO3\CMS\Backend\Rte\AbstractRte , \TYPO3\CMS\Rtehtmlarea\RteHtmlAreaBase and \TYPO3\CMS\Rtehtmlarea\RteHtmlAreaApi . These three main API were removed or changed method signatures and internal method calls.

The functionality to render RTE standalone and out of a context of FormEngine was dropped.


Main API changes

  • Method TYPO3\CMS\Backend\Utility\BackendUtility::RTEgetObj() is deprecated and no longer used. FormEngine now creates a RichTextElement with NodeFactory and makeInstance() , the created object is not a singleton but a prototype.
  • With the deprecation of RTEgetObj method transformContent from AbstractRte has been inlined to DataHandler .
  • Method isAvailable from AbstractRte has been dropped. Every valid browser and browser version for TYPO3 CMS 7 can render the default richtext editor. Custom checks may be implement via NodeResolverInterface in FormEngine .
  • Property RTE_errors in TYPO3\CMS\Core\Authentication\BackendUserAuthentication has been dropped along with the RTEgetObj() deprecation.

RTE registration

  • Different richtext implementations can no longer register in $GLOBALS['TYPO3_CONF_VARS']['BE']['RTE_reg'] . Instead, registration must be done in FormEngine via NodeFactory API, the method drawRTE has been dropped.
  • Transformations are not available via AbstractRte anymore, hooks within RteHtmlParser can be used for custom transformations.

PHP classes

  • \TYPO3\CMS\Backend\Rte\AbstractRte has been dropped.
  • \TYPO3\CMS\Rtehtmlarea\RteHtmlAreaBase has been dropped and its functionality was moved to \TYPO3\CMS\Rtehtmlarea\Form\Element\RichtextElement . All methods and properties except the main entry method render() used by FormEngine are protected.
  • \TYPO3\CMS\Rtehtmlarea\RteHtmlAreaApi has been refactored. Method main() receives a configuration array instead of an instance of the parent object. Some methods were dropped and are no longer called.

RTE Plugin Configuration

  • Parameter $GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['anExtensionKey']['plugins']['aPluginName']['addIconsToSkin'] was dropped, plugin property relativePathToSkin is no longer evaluated.
  • A couple of helper methods were added to RteHtmlAreaApi
  • This API may get further changes in the future.
