TYPO3 Configuration Basics
==========================

Just in case you are not familiar with how to configure TYPO3, we will
give you a very brief introduction. Otherwise, you can safely
skip this part and continue reading
:ref:`config-concepts`.

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


.. _config-typo3-page-tsconfig:

Page TSconfig
=============

Relevant Settings for `rte_ckeditor`
------------------------------------

Page TSconfig can be used to change:

#.  Default preset::

      RTE.default.preset = full

#. Override for one field (:typoscript:`RTE.config.[tableName].[fieldName].preset`)::

      RTE.config.tt_content.bodytext.preset = myCustomPreset
      RTE.config.tx_news_domain_model_news.bodytext.preset = minimal

#. Override for one field defined in flexform (:typoscript:`RTE.config.[tableName].[flexForm.field.name].preset`)::

      RTE.config.tt_content.settings.notifications.emailText.preset = myCustomPreset

#. Override for one field, if type matches (:typoscript:`RTE.config.[tableName].[fieldName].types.[type].preset`)::

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

For more examples, see :ref:`t3tsconfig:pageTsRte` 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.

#. Go to the :guilabel:`Web > Page` module.
#. Select a page in the page tree (usually your root page).
#. Click on the button to :guilabel:`Edit page properties`

   .. figure:: images/edit_page_properties.png
      :class: with-shadow

#. Select the :guilabel:`Resources` tab
#. Enter the Page TSconfig in the field :guilabel:`"Page TSconfig"`


Additionally, you can add Page TSconfig in an extension: :file:`Configuration/TSconfig/Page`, see
:ref:`best-practice-sitepackage`.

How to view settings
--------------------

Go to the module :guilabel:`Web > Info` and select :guilabel:`Page TSconfig`.


.. _config-typo3-global-configuration:

Global Configuration
====================

Global Configuration is a system-wide general configuration.

Relevant Settings for `rte_ckeditor`
------------------------------------

The setting :php:`$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
:guilabel:`Admin Tools > Settings > Configure Installation-Wide Options`.

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

You must either configure this in:

#. The file :file:`typo3conf/AdditionalConfiguration.php`
#. Or in an extension in the file :file:`EXT:<extkey>/ext_localconf.php`

.. code-block:: 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
:guilabel:`System > Configuration > $GLOBAL['TYPO3_CONF_VARS'] (Global Configuration) > RTE`.

.. figure:: images/global-configuration-rte.png
   :class: with-shadow

   Global Configuration: RTE > Presets



.. _config-typo3-yaml:

YAML
====

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


Relevant Settings for `rte_ckeditor`
------------------------------------

See :ref:`config-ref`

How to change values
--------------------

This is done directly in the file. The YAML file should be included in a
sitepackage extension, see :ref:`best-practice-sitepackage`.


.. _config-typo3-tca:

TCA
===

The :abbr:`table configuration array (TCA)` 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`
------------------------------------

* :ref:`t3tca:columns-text-properties-enableRichtext`
* :ref:`t3tca:columns-text-properties-richtextConfiguration`

How to change values
--------------------

This must be done in an extension in :file:`Configuration/TCA`. Usually this is done within a custom sitepackage
extension, see :ref:`best-practice-sitepackage`.

How to view settings
--------------------

You can view TCA in the backend:
:guilabel:`System > Configuration > $GLOBAL['TCA'] (Table configuration array)`.

For example, look at :guilabel:`tt_content > columns > bodytext`.

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

.. figure:: images/column_overrides.png
   :class: with-shadow

   TCA: tt_content > types > text > columnsOverrides > bodytext
