Breaking: #67811 - Rte API

See forge#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.
