About this extension

This extension adds list items to tt_content. It adds a database field tx_listelements_list to tt_content that allows adding flexible list items as IRRE records to any content element.

Installation

Add the extension to your project by installing and adding the TypoScript setup to your site-Extension setup:

@import 'EXT:listelements/Configuration/TypoScript/setup.typoscript'

This adds the configuration for adding the list items as an array listitems to the variables available for your content element's Fluid template, like this:

<f:for each="{listitems}" as="item">
    ...    
</f:for>

Backend PageLayoutView preview

This extension adds a Hook and a Service class to allow customized display using Fluid templates for the backend Page Layout View. Use this to add customized preview data if you add additional assets/image fields to be resolved for backend preview:

EXT:site_extension/Classes/Hooks/DrawItem.php:

<?php

namespace B13\SiteExtension\Hooks;

use TYPO3\CMS\Backend\View\PageLayoutViewDrawItemHookInterface;
use TYPO3\CMS\Backend\View\PageLayoutView;

/**
 * Class/Function to manipulate the rendering of item preview content
 *
 */
class DrawItem implements PageLayoutViewDrawItemHookInterface
{

    /**
     * @param PageLayoutView $parentObject : The parent object that triggered this hook
     * @param boolean $drawItem : A switch to tell the parent object, if the item still must be drawn
     * @param string $headerContent : The content of the item header
     * @param string $itemContent : The content of the item itself
     * @param array $row : The current data row for this item
     *
     * @return void
     */
    public function preProcess(PageLayoutView &$parentObject, &$drawItem, &$headerContent, &$itemContent, array &$row)
    {

        // get all list items (database column 'test_list') including all assets
        if ($row['test_list']) {
            // array &$row, $field = '', $table = 'tt_content', $filereferences = 'assets, additional_assets'
            \B13\Listelements\Service\ListService::resolveListitems($row, 'test_list', 'tt_content');
        }

    }

}

Important info on configuration

Remember to add the hiddenpalette to all showitems-configuration for your own content elements to have invisible fields like the language uid saved for all list items.
