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.
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>
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');
}
}
}
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.
