TYPO3 8在textmedia的后端预览中显示布局选择

Question

我尝试尽可能地使用和自定义fluid_styled_content的CType。 因此，选择字段“布局”非常有用，可以选择一些不同的样式（例如红色框，阴影或图像填充）。 但是，如果您有选择的余地，它不会显示在后端预览中，则每个元素看起来都一样。

有没有一种方法可以在textmedia的后端预览中在布局字段中显示所选值？

为此，请注册一个钩子（路径：yourextension / Classes / Hooks / PageLayoutView / TextMediaCustomPreviewRenderer.php），如下所示：

    <?php
namespace Vendor\Yourextension\Hooks\PageLayoutView;

use \TYPO3\CMS\Backend\View\PageLayoutViewDrawItemHookInterface;
use \TYPO3\CMS\Backend\View\PageLayoutView;

/**
 * Contains a preview rendering for the page module of CType="textmedia"
 */
class TextMediaCustomPreviewRenderer implements PageLayoutViewDrawItemHookInterface
{

   /**
    * Preprocesses the preview rendering of a content element of type "Text Media"
    *
    * @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 $row Record row of tt_content
    *
    * @return void
    */
   public function preProcess(
      PageLayoutView &$parentObject,
      &$drawItem,
      &$headerContent,
      &$itemContent,
      array &$row
   )
   {
      $pageTs = \TYPO3\CMS\Backend\Utility\BackendUtility::getPagesTSconfig($row['pid']);
      if ($row['CType'] === 'textmedia') {
         $itemContent .= '<p>Layoutversion: ' . $pageTs['TCEFORM.']['tt_content.']['layout.']['types.']['textmedia.']['addItems.'][$row['layout']] . '</p>';

         if ($row['bodytext']) {
             $itemContent .= $parentObject->linkEditContent(
                     $parentObject->renderText($row['bodytext']),
                     $row
                 ) . '<br />';
         }
         if ($row['assets']) {
             $itemContent .= $parentObject->thumbCode($row, 'tt_content', 'assets') . '<br />';
         }
         $drawItem = false;
      }
   }
}

然后在ext_localconf.php中输入：

    // Register for hook to show preview of tt_content element of CType="textmedia" in page module
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['cms/layout/class.tx_cms_layout.php']['tt_content_drawItem']['textmedia'] = \Vendor\Yourextension\Hooks\PageLayoutView\TextMediaCustomPreviewRenderer::class;

就我而言，我在pageTsconfig中提供了select的不同选项，如下所示：

    TCEFORM.tt_content.layout.types.textmedia.addItems {
    50 = Textbox grau, Bildergalerie oben
    60 = Textbox grau, Bildergalerie unten
    110 = Blau, rechtsbündig
    210 = Hellblau, linksbündig
    220 = Rot, linksbündig
    310 = Akkordeon
}

这是通过locallang.xlf使用正确的语言处理的更好方法。 如果那样做，也许您需要稍微更改一下代码示例...
