TYPO3: How to configure plugin preview in Backend

问题

In the backend I want to display some configurations of the plugin the editor has selected. Like in powermail or news plugin. How can this be achieved?

You'd apply the same logic as for a custom preview of any custom element:

• You can use PageTS to register a custom Fluid template:

  // Register preview for a custom content element
  mod.web_layout.tt_content.preview.my_content_element = EXT:my_ext/Resources/Private/Templates/Preview/MyContentElement.html
  // Register preview for a plugin
  mod.web_layout.tt_content.preview.list.myext_myplugin = EXT:my_ext/Resources/Private/Templates/Preview/MyPlugin.html
  

• Alternatively you can implement the tt_content_drawItem hook:

  $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['cms/layout/class.tx_cms_layout.php']['tt_content_drawItem']['fluid_styled_slider'] = \Acme\Package\MyPreviewRenderer::class;
  

  And then implement this hook:

  namespace Acme\Package;
  
  use TYPO3\CMS\Backend\View\PageLayoutViewDrawItemHookInterface;
  
  class MyPreviewRenderer implements PageLayoutViewDrawItemHookInterface
  {
      /**
       * ...
       */
      public function preProcess(PageLayoutView &$parentObject, &$drawItem, &$headerContent, &$itemContent, array &$row)
      {
          // 1. Check $row['CType'] for your content element and $row['list_type'] for your plugin in case of "list"
          // 2. Fill $itemContent with your preview
          // 3. Set $drawItem = false; to prevent rendering of the default preview
      }
  }
