I'm still stuck realizing a BE-preview of my new defined CEs in 7.6.0
in ext_localconf.php I have:
$GLOBALS['TYPO3_CONF_VARS']
['SC_OPTIONS']
['cms/layout/class.tx_cms_layout.php']['tt_content_drawItem']
['my_textpic'] =
\ME\MyConfig\Hooks\PageLayoutView\MyTextPicPreviewRenderer::class;
in
EXT:my_config/Classes/Hooks/PageLayoutView/MyTextPicPreviewRenderer.php
I have:
----------------------
<?php
namespace ME\MyConfig\Hooks\PageLayoutView;
use \TYPO3\CMS\Backend\View\PageLayoutViewDrawItemHookInterface;
use \TYPO3\CMS\Backend\View\PageLayoutView;
class MyTextPicPreviewRenderer implements
\TYPO3\CMS\Backend\View\PageLayoutViewDrawItemHookInterface
{
/**
* Preprocesses the preview rendering of a content element of type
"my_textpic"
*
* @param \TYPO3\CMS\Backend\View\PageLayoutView $parentObject
Calling parent object
* @param bool $drawItem Whether to draw the item using the default
functionality
* @param string $headerContent Header content
* @param string $itemContent Item content
* @param array $row Record row of tt_content
*
* @return void
*/
public function preProcess(
\TYPO3\CMS\Backend\View\PageLayoutView &$parentObject,
&$drawItem,
&$headerContent,
&$itemContent,
array &$row
)
{
if ($row['CType'] === 'my_textpic') {
:
}
}
}
?>
------------------
but all I get in the BE is:
#1218547409: $hookObject must implement interface
TYPO3\CMS\Backend\View\PageLayoutViewDrawItemHookInterface
I found multiple examples how to build (and preview) own CEs but all
work in differnt kinds and with different syntax (which evolves from 4.3
to 7.6)
- - - - -
The other way for own previews I found was in page.TSconfig:
mod.web_layout.tt_content.preview {
my_textpic =
EXT:my_config/Resources/Private/Templates/Preview/TextPic.html
}
but that did not work either for my own CEs (just for CEs from FSC)
the default preview includes headline and text, but also I use the field
'assets' for images/videos (like in the text&media CEs from FSC) there
is no preview of the images, which is very inconvenient for editors.
previously I used the field 'image' (like in the old textpic CE from
CSC) and there was a preview of the images by default.
anyone who can help to analyze the errors or give me a hand for a
working full preview?
