This solution was working til TYPO3 8.7
. But breaks in TYPO3 9
.
I've some submenu
showing images from page-resources
and using categories.descriptions
for css
.
I use custom viewhelpers
for that. But now the JOIN-sql
is broken... Don't know why, because it worked in 8.7
and previous.

$result = $query->execute();

$res[] = $row;
}

Can anybody check those queryBuilder-statements?
Thanx in advance

Here's the solution:
FalResourceViewhelper
Just use the TYPO3-core-method $fileRepository->findByRelation(); This returns the page-related resources. Use like this:
<e:falResource data="{page.data}" table="pages" field="media" as="sysFileArray">
<f:if condition="{sysFileArray.0.uid}!=0">
<f:image src="{sysFileArray.0.uid}" treatIdAsReference="1" class="img-responsive"/>
</f:if>
</e:falResouce>

namespace EnzephaloN\ThemePsoa\ViewHelper;
use TYPO3\CMS\Core\Resource\FileRepository;
use TYPO3\CMS\Core\Utility\GeneralUtility;

use TYPO3Fluid\Fluid\Core\ViewHelper\Traits\CompileWithRenderStatic;
/**

$this->registerArgument('field', 'string', 'field', false, 'image');
$this->registerArgument('as', 'string', 'Name of variable to create', false, 'items');
}
/**

public static function renderStatic(array $arguments, \Closure $renderChildrenClosure, RenderingContextInterface $renderingContext) {
$variableProvider = $renderingContext->getVariableProvider();
if (is_array($arguments['data']) && $arguments['data']['uid'] && $arguments['data'][$arguments['field']]) {
$fileRepository = GeneralUtility::makeInstance(FileRepository::class);
$items = $fileRepository->findByRelation(
$arguments['table'],
$arguments['field'],
$arguments['data']['uid']
);
$localizedId = null;
if (isset($arguments['data']['_LOCALIZED_UID'])) {
$localizedId = $arguments['data']['_LOCALIZED_UID'];
} elseif (isset($arguments['data']['_PAGES_OVERLAY_UID'])) {
$localizedId = $arguments['data']['_PAGES_OVERLAY_UID'];
}
$isTableLocalizable = (
!empty($GLOBALS['TCA'][$arguments['table']]['ctrl']['languageField'])

if ($isTableLocalizable && $localizedId !== null) {
$items = $fileRepository->findByRelation($arguments['table'], $arguments['field'], $localizedId);

} else {
$items = null;
}
$variableProvider->add($arguments['as'], $items);
$content = $renderChildrenClosure();
$variableProvider->remove($arguments['as']);
return $content;
}
}
It's easy.

SysCategoryViewHelper works like this:
<e:sysCategory data="{page.data}" as="sysCategoryDetailArray">
<f:if condition="{sysCategoryDetailArray.0}">
<i class="fa fa-4x {sysCategoryDetailArray.0.description}"></i>
</f:if>
</e:sysCategory>
