Вам необходимо добавить новое поле в sys_file_reference
TCA:
Конфигурация / TCA / Заменяет / sys_file_reference.php
\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addTCAcolumns(
'sys_file_reference',
[
'tx_myext_description' => [
'label' => 'My field description',
'config' => [
'type' => 'text',
'cols' => '80',
'rows' => '15',
'enableRichtext' => true,
'richtextConfiguration' => 'default'
]
],
]
);
ext_tables.sql
CREATE TABLE sys_file_reference (
tx_myext_description mediumtext,
);
Не забудьте добавить новое поле в базу данных (используя инструмент сравнения баз данных в инструменте установки).
Затем используйте его в TCA вашего нового слайдера:
Конфигурация / TCA / Заменяет / tt_content.php
$GLOBALS['TCA']['tt_content']['types']['my_slider'] = [
'showitem' => '
--div--;LLL:EXT:core/Resources/Private/Language/Form/locallang_tabs.xlf:general,
--palette--;LLL:EXT:frontend/Resources/Private/Language/locallang_ttc.xlf:palette.general;general,
--palette--;LLL:EXT:frontend/Resources/Private/Language/locallang_ttc.xlf:palette.headers;headers,bodytext,assets;LLL:EXT:frontend/Resources/Private/Language/locallang_ttc.xlf:tabs.media,
',
'columnsOverrides' => [
'bodytext' => [
'config' => [
'enableRichtext' => true,
'richtextConfiguration' => 'default'
]
],
'assets' => [
'config' => [
'overrideChildTca' => [
'types' => [
0 => ['showitem' => $GLOBALS['TCA']['sys_file_reference']['types'][0]['showitem'].',tx_myext_description'],
\TYPO3\CMS\Core\Resource\File::FILETYPE_TEXT => [
'showitem' => $GLOBALS['TCA']['sys_file_reference']['types'][\TYPO3\CMS\Core\Resource\File::FILETYPE_TEXT]['showitem'].',tx_myext_description'
],
\TYPO3\CMS\Core\Resource\File::FILETYPE_IMAGE => [
'showitem' => $GLOBALS['TCA']['sys_file_reference']['types'][\TYPO3\CMS\Core\Resource\File::FILETYPE_IMAGE]['showitem'].',tx_myext_description'
],
\TYPO3\CMS\Core\Resource\File::FILETYPE_AUDIO => [
'showitem' => $GLOBALS['TCA']['sys_file_reference']['types'][\TYPO3\CMS\Core\Resource\File::FILETYPE_AUDIO]['showitem'].',tx_myext_description'
],
\TYPO3\CMS\Core\Resource\File::FILETYPE_VIDEO => [
'showitem' => $GLOBALS['TCA']['sys_file_reference']['types'][\TYPO3\CMS\Core\Resource\File::FILETYPE_VIDEO]['showitem'].',tx_myext_description'
],
\TYPO3\CMS\Core\Resource\File::FILETYPE_APPLICATION => [
'showitem' => $GLOBALS['TCA']['sys_file_reference']['types'][\TYPO3\CMS\Core\Resource\File::FILETYPE_APPLICATION]['showitem'].',tx_myext_description'
],
],
],
],
],
],
];
И тогда ваш шаблон Fluid может выглядеть так:
Slider.html
<html xmlns:f="http://typo3.org/ns/TYPO3/CMS/Fluid/ViewHelpers"
data-namespace-typo3-fluid="true">
<h1>{data.header}</h1>
<p>{data.bodytext}</p>
<f:for each="{images}" as="image">
<f:image image="{image}" alt="{file.properties.alt}" cropVariant="desktop"/>
{image.properties.tx_myext_description -> f:format.html()}
</f:for>
</html>
