About this extension

This extension adds a hook for rendering content element previews for TYPO3's backend view in the page module, adding the ability to use Fluid Partials and Layouts to enable consistent preview markup.

Requirements

TYPO3 v10.4, v11.5, v12.4, v13.4 or v14
PHP 7.4 or higher

Installation

Use composer to add this content element to your project

composer require b13/backendpreviews

and install the extension using the Extension Manager in your TYPO3 backend.

Add configuration

Add this to your PageTsConfig to include the default Fluid Templates provided with this extension:

@import 'EXT:backendpreviews/Configuration/PageTs/PageTs.tsconfig'

On TYPO3 v13 and v14 you can alternatively include the shipped site set b13/backendpreviews as a dependency of your own site set (Configuration/Sets/<YourSet>/settings.yaml) instead of importing the PageTsConfig manually:

dependencies:
  - b13/backendpreviews

You can add your own paths to the setup using PageTsConfig in your own site-extension:

mod.web_layout.tt_content.preview.view {
  layoutRootPaths.10 = EXT:site_example/Resources/Private/Contenttypes/Backend/Layouts
  partialRootPaths.10 = EXT:site_example/Resources/Private/Contenttypes/Backend/Partials
  templateRootPaths.10 = EXT:site_example/Resources/Private/Contenttypes/Backend/Templates
}

By default, we will try to find a template to render a preview based on the CType of the element, meaning for CType mytype we will try to find a template named Mytype.html in one of the paths defined in the templateRootPaths-Array.

You can set a different templateName explicitly like this:

mod.web_layout.tt_content.preview.template.mytype = Myowntemplate

For plugins a template name for a specific plugin can be specified like this:

mod.web_layout.tt_content.preview.template.list.mylist_type = Listtypetemplate

All flexform data of the plugin are available in {pi_flexform_transformed} to create meaningful previews:

<b>Page:</b> {pi_flexform_transformed.settings.page}

Use custom backend previews for default CTypes

Default CTypes for fluid_styled_content define dedicated previewRenderer classes. If you want to use EXT:backendpreviews instead, remove the configuration for each of these CTypes in your extension's ext_localconf.php:

unset($GLOBALS['TCA']['tt_content']['types']['textpic']['previewRenderer']);

ViewHelpers

To make it easier to build your own preview templates, the extension ships a few ViewHelpers in the namespace B13\Backendpreviews\ViewHelpers. Register them in your template like this:

<html
	xmlns:f="http://typo3.org/ns/TYPO3/CMS/Fluid/ViewHelpers"
	xmlns:b13="http://typo3.org/ns/B13/Backendpreviews/ViewHelpers"
	data-namespace-typo3-fluid="true"
>

b13:renderBodytext – prepares a bodytext value for a preview: strips tags (keeping ol, ul, li by default), crops to a number of characters (crop, default 1500, 0 disables cropping) and converts newlines to <br>.
```
{text -> b13:renderBodytext(crop: 200) -> f:format.raw()}
```
b13:getDatabaseRecord – fetches database record(s) by uid (or a comma-separated uidList) from a table (table, default tt_content) so their fields can be used inside the preview.
b13:explodeList – splits a list value into an array you can iterate over with f:for, either by a character (splitChar, default ,) or by newlines (splitNL).
