b13 / backendpreviews Goto Github PK

When showing four database records in a backend preview of an element, the order of the records should reflect the sorting order of the uidList handed to the viewhelper.

The supported TYPO3 version isn't defined yet in composer.json, this makes it really hard in the future to have newer versions of b13/backendpreview to be limited to e.g. TYPO3 < v12.

When installing an activating the extension, following exception is thrown in the page module, in case the TSconfig was not yet included:

(1/1) TypeError Argument 1 passed to TYPO3\CMS\Fluid\View\AbstractTemplateView::setLayoutRootPaths() must be of the type array, null given, called in /var/www/html/typo3conf/ext/backendpreviews/Classes/Hooks/BackendPreviewRenderer.php on line 61

I have just tried your fabulous extension on an TYPO3 v12 installation. Great extension, as always! It just took me a little longer to find out why I can't overwrite the backend previews of the following ctypes: text, textmedia, textpic and images.

The reason is that in the TCA
vendor/typo3/cms-frontend/Configuration/TCA/tt_content.php explicit previewRenderers
are assigned to these ctypes:
'previewRenderer' => \TYPO3\CMS\Frontend\Preview\TextPreviewRenderer::class

I therefore had to explicitly overwrite the previewRenderer for these ctypes:
// override textmedia previewRenderer $GLOBALS['TCA']['tt_content']['types']['textmedia']['previewRenderer'] = \B13\Backendpreviews\Backend\Preview\StandardContentPreviewRenderer::class;

Is this the right way, or have I overlooked something?
