RTE¶

The RTE prefix key is used for configuration of the Rich Text Editor. Please refer to the RTE chapter in Core API document for more general information on RTE configuration and data processing.

The order in which configuration for the RTE is loaded is:

preset defined for a specific field via PageTS
richtextConfiguration defined for a specific field via TCA
general preset defined via PageTS
default

The full property path building is a bit more complex than for other property segments. The goal is that global options can be set that can also be overriden in more specific situations:

Configure all RTE for all tables, fields and types:: RTE.default
Configure RTE for a specific field in a table: RTE.config.[tableName].[fieldName]
Configure RTE for a specific field in a table for a specific record type: RTE.config.[tableName].[fieldName].types.[type]

Consider the following Page TSconfig examples:

EXT:site_package/Configuration/page.tsconfig¶

# Disable all RTEs
RTE.default.disabled = 1

EXT:site_package/Configuration/page.tsconfig¶

# Disable all RTEs
RTE.default.disabled = 1
# Enable RTE for the tt_content bodytext field only
RTE.config.tt_content.bodytext.disabled = 0

EXT:site_package/Configuration/page.tsconfig¶

# Disable all RTEs
RTE.default.disabled = 1
# Enable RTE for the tt_content bodytext field only
RTE.config.tt_content.bodytext.disabled = 0
# But disable RTE for tt_content bodytext again if the record type is "text"
RTE.config.tt_content.bodytext.types.text.disabled = 1

disabled ¶

Datatype: boolean
Description: If set, the editor is disabled. This option is evaluated in \TYPO3\CMS\Backend\Form\FormEngine where it determines whether the RTE is rendered or not. Note that a backend user can also ultimately disable RTE's in his user settings.

config ¶

contentsLanguageDirection ¶

Datatype: rtl or ltr

Description

The configuration contentsLangDirection of the ckeditor is used to define the direction of the content. It is filled by the direction defined in the site language of the current element.

As fallback the following page TsConfig configuration can be used:
EXT:my_sitepackage/Configuration/page.tsconfig¶
# always use right to left
RTE.config.contentsLanguageDirection = rtl

# except for the following language:
[siteLanguage("locale") == "en_US"]
    RTE.config.contentsLanguageDirection = ltr
[END]

The proc section allows customization of the server processing of the content, see the transformation section of the RTE chapter in the core API document for more general information on server processing.

The proc properties are in \TYPO3\CMS\Core\Html\RteHtmlParser and are universal for all RTEs. The main objective of these options is to allow for minor configuration of the transformations. For instance you may disable the mapping between - and - tags which is done by the ts_transform transformation.

Notice how many properties relate to specific transformations only! Also notice that the meta-transformations ts_css imply other transformations.

This means that options limited to ts_transform will also work for ts_css of course.

allowedClasses ¶

Datatype

string with comma separated values

Description

Applies for ts_transform and css_transform only.

Direction: From RTE to database, saving a record.

Allowed general class names when content is stored in database. Could be a list matching the number of defined classes you have. Class names are case insensitive.

This might be a really good idea to do, because when pasting in content from MS word for instance there are a lot of  and  tags which may have class names in. So by setting a list of allowed classes, such foreign class names are removed.

If a class name is not found in this list, the default is to remove the class.

allowTags ¶

Datatype

string with comma separated values

Description

Applies for ts_transform and css_transform only.

Tags to allow. Notice, this list is added to the default list, which you see here:

b,i,u,a,img,br,div,center,pre,font,hr,sub,sup,p,strong,em,li,ul,ol,blo ckquote,strike,span

allowTagsOutside ¶

Datatype

string with comma separated values

Description

Applies for ts_transform and css_transform only.

Enter tags which are allowed outside of  and <DIV> sections when converted back to database.

Default

address, article, aside, blockquote, footer, header, hr, nav, section, div

Example

EXT:site_package/Configuration/page.tsconfig¶

# Allow only hr tags outside of p and div
RTE.default.proc.allowTagsOutside = hr

blockElementList ¶

Datatype: string with comma separated values
Description: Comma-separated list of uppercase tags (e.g. P,HR) that overrides the list of HTML elements that will be treated as block elements by the RTE transformations.

denyTags ¶

Datatype

string with comma separated values

Description

Applies for ts_transform and css_transform only.

Tags from above list to disallow.

entryHTMLparser_db ¶

Datatype

boolean / HTMLparser

Description

Applies to all kinds of processing.

Allows to enable / disable the HTMLparser before the content is processed with the predefined processors (e.g. ts_images or ts_transform).

entryHTMLparser_rte ¶

Datatype

boolean / HTMLparser

Description

Applies to all kinds of processing.

Allows to enable / disable the HTMLparser before the content is processed with the predefined processors (e.g. ts_images or ts_transform).

exitHTMLparser_db ¶

Datatype

boolean / HTMLparser

Description

Applies to all kinds of processing.

Allows to enable / disable the HTMLparser after the content is processed with the predefined processors (e.g. ts_images or ts_transform).

exitHTMLparser_rte ¶

Datatype

boolean / HTMLparser

Description

Applies to all kinds of processing.

Allows to enable / disable the HTMLparser after the content is processed with the predefined processors (e.g. ts_images or ts_transform).

HTMLparser_db ¶

Datatype

HTMLparser

Description

Applies for ts_transform and css_transform only.

These are additional options to the HTML parser calls which strips of tags when the content is prepared from the RTE to the database, saving a record. It is possible to configure additional rules like which other tags to preserve, which attributes to preserve, which values are allowed as attributes of a certain tag etc.

For the detailed list of properties, see the section of the TypoScript reference.

Note

This configuration is similar in frontend TypoScript and Page TSconfig. This is why single properties can be looked up in the TypoScript reference.

Also note the HTMLparser options keepNonMatchedTags and htmlSpecialChars are not observed. They are preset internally.

Sanitization¶

New in version 9.5.29/10.4.19.

An HTML sanitizer is available to sanitize and remove XSS from markup. It strips tags, attributes and values that are not explicitly allowed.

Sanitization for persisting data is disabled by default and can be enabled globally by using the corresponding feature flag in the configuration files config/system/settings.php or config/system/additional.php:

$GLOBALS['TYPO3_CONF_VARS']['SYS']['features']['security.backend.htmlSanitizeRte'] = true;

It can then be disabled per use case with a custom processing instruction:

EXT:site_package/Configuration/Processing.yaml¶

processing:
  allowTags:
    # ...
  HTMLparser_db:
    # ...
    # disable individually per use case
    htmlSanitize: false

    # This is the default configuration,
    # the feature flag has to be enabled
    htmlSanitize:
      # use default builder as configured in
      # $GLOBALS['TYPO3_CONF_VARS']['SYS']['htmlSanitizer']
      build: default

HTMLparser_rte ¶

Datatype

HTMLparser

Description

Applies for ts_transform and css_transform only.

These are additional options to the HTML parser calls which strips of tags when the content is prepared from the database to the RTE rendering. It is possible to configure additional rules like which other tags to preserve, which attributes to preserve, which values are allowed as attributes of a certain tag etc.

For the detailed list of properties, see the section of the TypoScript reference.

Note

This configuration is similar in frontend TypoScript and Page TSconfig. This is why single properties can be looked up in the TypoScript reference.

Also note the HTMLparser options keepNonMatchedTags and htmlSpecialChars are not observed. They are preset internally.

overruleMode ¶

Datatype: Comma list of RTE transformations
Description: This can overrule the RTE transformation set from TCA. Notice, this is a comma list of transformation keys.
