TYPO3 Configuration Basics

Just in case you are not familiar with how to configure TYPO3, we will give you a very brief introduction. In case you are , you can safely skip this part and continue reading Configuration Concepts.

We only cover configuration methods that are used to configure rte_ckeditor.

Page TSconfig

Relevant Settings for rte_ckeditor

Page TSconfig can be used to change:

  1. Default preset:

    RTE.default.preset = full
  2. Override for one field (RTE.config.[tableName].[fieldName].preset):

    RTE.config.tt_content.bodytext.preset = myCustomPreset
    RTE.config.tx_news_domain_model_news.bodytext.preset = minimal
  3. Override for one field defined in flexform (RTE.config.[tableName].[flexForm\.field\.name].preset):

    RTE.config.tt_content.settings\.notifications\.emailText.preset = myCustomPreset
  4. Override for one field, if type matches (RTE.config.[tableName].[fieldName].types.[type].preset):

    RTE.config.tt_content.bodytext.types.textmedia.preset = minimal

For more examples, see RTE in “TSconfig Reference”.

How to change values

As Page TSconfig always applies to a page and its subpages, you can modify it by editing a page.

  1. Go to the “WEB” > “Page” module.

  2. Select a page in the page tree (usually your root page).

  3. Click on the button to Edit page properties

  4. Select the “Resources” tab

  5. Enter the Page TSconfig in the field “Page TSconfig”

Additionally, you can add Page TSconfig in an extension: Configuration/TSconfig/Page, see Use a Sitepackage Extension.

How to view settings

Go to the module “WEB” > “Info” and select “Page TSconfig”.

Global Configuration

Global Configuration is system wide general configuration.

Relevant Settings for rte_ckeditor

The setting $GLOBALS['TYPO3_CONF_VARS']['RTE']['Presets'] is used to configure the available presets for rich text editing.

By default, the presets “minimal”, “default” and “full” are defined.

If you add a new preset, you must add it to this array.

How to change values

Usually, Global Configuration can be configured in the backend in “ADMIN TOOLS” > “Settings” > “Configure Installation-Wide Options”.

However, the settings relevant for rich text editing, $GLOBALS['TYPO3_CONF_VARS']['RTE']['Presets'] cannot be configured in the backend.

You must either configure this in:

  1. The file typo3conf/AdditionalConfiguration.php
  2. Or in an extension in the file EXT:<extkey>/ext_localconf.php
if (empty($GLOBALS['TYPO3_CONF_VARS']['RTE']['Presets']['myCustomPreset'])) {
    $GLOBALS['TYPO3_CONF_VARS']['RTE']['Presets']['myCustomPreset'] = 'EXT:<extkey>/Configuration/RTE/MyCustomPreset.yaml';

How to view settings

You can view the Global Configuration in “SYSTEM” > “Configuration” > “$GLOBAL[‘TYPO3_CONF_VARS’] (Global Configuration)” > “RTE”.


Global Configuration: RTE > Presets


Most of the configuration of rte_ckeditor will be done in a Yaml file.

Relevant Settings for rte_ckeditor

See Configuration Reference

How to change values

This is done directly in the file. The Yaml file should be included in a sitepackage extension, see Use a Sitepackage Extension.


The table configuration array is used to configure database fields and how they will behave in the backend when edited. It is for example used to define that tt_content.bodytext should be edited with a rich text editor.

Relevant Settings for rte_ckeditor

How to change values

This must be done in an extension in Configuration/TCA. Usually this is done within a custom sitepackage extension, see Use a Sitepackage Extension.

How to view settings

You can view TCA in the backend: “SYSTEM” > “Configuration” > “$GLOBAL[‘TCA’] (Table configuration array)”.

For example, look at tt_content > columns > bodytext.

However, you will find that neither enableRichtext, nor richtextConfiguration is set here. They are configured in tt_content > types for various content types, for example look at tt_content > types > text > columnOverrides.


TCA: tt_content > types > text > columnsOverride > bodytext
