REMIND - Headless Extension

This extension provides:

• base content elements
• additional fields for pages and tt_content (e.g. items)
• extended flex form processor
• image processing middleware
• route enhancer for query params
• base configuration for form_framework
• a default backend layout

Installation

Use comoser to install the extension using composer install remind/headless. Import typoscript in your provider extension.

Add the following to your site config for backend layouts to work:

imports:
  - { resource: "EXT:rmnd_headless/Configuration/Site/settings.yaml" }

Dependencies

Required dependencies are headless and content-defender. The latter is used in the default backend layout.

Backend Layouts

Default

The default layout consists of 1 column with 3 rows. Besides the main content (colPos = 0) there is also one column for content above the breadcrumbs (colPos = 1) and the footer (colPos = 10).

The content defender extension is used to only allow exactly one footer_content content element in the footer column. The footer_content content element can not be used in the other columns.

TCA

tt_content

tx_headless_item

Field of type inline. Basically tx_headless_item acts like tt_content without a colPos. Used for accordion, header_slider and tabs. See one of these definition on how to use items and override the showitem definition.

header_layout

Values for text, H1-H6 and hidden.

tx_headless_background_color

A background color for all content elements. Choice between none, primary, secondary, accent, white and black.

tx_headless_background_full_width

Only visible if tx_headless_background_color is other than none. Used to extend the background color to full width instead of the content container only.

tx_headless_space_before_inside

Addition to space_before. Space before the content element, but inside the background color. Only available if tx_headless_background_color is other than none.

tx_headless_space_after_inside

Similar to space_before_inside.

pages

tx_headless_overview_label

An tx_headless_overview_label field is added to the page TCA. The field should be used to customize the label for the overview pages.

Content Elements

accordion

Uses tx_headless_item, items consist of text (header, subheader, bodytext) only.

footer_content

Basic definition without any actual content fields. Add a flexform in your provider extension to use footer_content:

\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addPiFlexFormValue(
    '*',
    'FILE:EXT:provider_extension/Configuration/FlexForms/FooterContent.xml',
    'footer_content'
);

header_slider

Header Slider content element that uses tx_headless_item. Consists of multiple slides with text and image. Autoplay can be enabled with duration between 500ms and 10000ms.

tabs

Uses tx_headless_item, items consist of text (header, subheader, bodytext) only.

QueryExtbase Route Enhancer

QueryExtbase Route Enhancer replaces extbase plugin query parameters with custom names and omits action and controller parameters.

limitToPages

Required for QueryExtbase route enhancer to work, because without limit all routes would match.

defaults

Behave the same as described here.

namespace, extension, plugin, _controller

Behave the same as described here.

_arguments

Replace the default query parameter name with a custom one. Key is the name, value the old. For Example tag: overwriteDemand/tags.

aspects

Aspects with the suffix Label should use LocaleModifier to replace the query parameter name with localized names. So if a query parameter with the argument page: currentPage and an Aspect with the key pageLabel exists, the localized names would be used.

types

Limit the route enhancer to certain page types, for example to enhance solr search result routes but not autocomplete routes. Defaults to [0].

example for News Extension

  News:
    limitToPages: [20]
    type: QueryExtbase
    extension: News
    plugin: Pi1
    _controller: 'News::list'
    defaults:
      page: '1'
    _arguments:
      page: currentPage
      category: overwriteDemand/categories
    aspects:
      page:
        type: StaticRangeMapper
        start: '1'
        end: '5'
	  pageLabel:
        type: LocaleModifier
        default: page
        localeMap:
          -
            locale: 'de_DE.*'
            value: seite
      category:
        type: PersistedAliasMapper
        tableName: sys_category
        routeFieldName: slug
	  categoryLabel:
        type: LocaleModifier
        default: category
        localeMap:
          -
            locale: 'de_DE.*'
            value: kategorie
