Indexing custom content fields

If you added fields to the tt_content table in order to use them with your own content elements, you can index these fields with the default page indexer, too.

Two hooks are needed:

  • One adds the new field to the list of fields fetched from the tt_content table,
  • the other one adds the field to the content written to the index.
  1. Register the hooks

    You need to register the hooks in your ext_localconf.php as follows:

    // Register hooks for indexing additional fields.
    $GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['ke_search']['modifyPageContentFields'][] =
    $GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['ke_search']['modifyContentFromContentElement'][] =
  2. Hook class

    class AdditionalContentFields {
       public function modifyPageContentFields(&$fields, $pageIndexer)
          // Add the field "subheader" from the tt_content table, which is normally
          // not indexed, to the list of fields.
          $fields .= ",subheader";
       public function modifyContentFromContentElement(string &$bodytext, array $ttContentRow, $pageIndexer)
          // Add the content of the field "subheader" to $bodytext, which is, what
          // will be saved to the index.
          $bodytext .= strip_tags($ttContentRow['subheader']);


You can find an example in the extension “ke_search_hooks”:
