Php – typo3 7.6 , News 6.3.0 – processDatamap_afterDatabaseOperations not working

Use case: When saving a news istance in backend I want to manipulate values before saving to database.

  • I include my hook in the following way in ext_localconf.php:

$GLOBALS[‘TYPO3_CONF_VARS’][‘SC_OPTIONS’][‘t3lib/class.t3lib_tcemain.php’][‘processDatamapClass’][]= VendormythemeHooksNewsControllerSettings::class;

  • In my Hooks I have write this code to Check if the Hook is Firing but it haven’t .

    <?php

 namespace VendormythemeHooks;

  class NewsControllerSettings {

          public function processDatamap_afterDatabaseOperations($status, $table, $id, &$fieldArray,TYPO3CMSCoreDataHandlingDataHandler $pObj){
              echo 'Hello world ! '; 
              exit();
          }
 }

I can’t upgrade the version of typo3 or even the news, but I don’t know what else to try.
I hope someone can help me. Opinions are also welcome.
Thanks in advance

    I think you don’t have the right signature for your method, parameter &$fieldArray, try this :

    <?php

namespace VendormythemeHooks;

class NewsControllerSettings {

  /**
   * Generate a different preview link     *
   *
   * @param string $status status
   * @param string $table table name
   * @param int $recordUid id of the record
   * @param array $fields fieldArray
   * @param TYPO3CMSCoreDataHandlingDataHandler $parentObject parent Object
   */
  public function processDatamap_afterDatabaseOperations(
      $status,
      $table,
      $recordUid,
      array $fields,
      TYPO3CMSCoreDataHandlingDataHandler $parentObject
  ) {
      echo 'Hello world ! '; 
      exit();
  }
}

    First, register the hook in the ext_localconf.php like so:

    <?php
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['t3lib/class.t3lib_tcemain.php']['processDatamap_afterDatabaseOperations'][] = VendorMythemeHooksDataHandlerHook::class . '->processDatamapAfterDatabaseOperations';

    Second, rename your namespace, as it doesn’t follow naming convention:

    <?php

namespace VendorMythemeHooks;

    Third, make sure your filestructure is accurate:

    <pre>
typo3conf/ext/mytheme/
├── Classes/
    └── Hooks/
        └── DataHandlerHook.php
</pre>

    Fourth, fix your PHP class and give the file a descriptive name like DataHandlerHook.php:

    <?php

namespace VendorMythemeHooks;

class DataHandlerHook
{
    /**
     * Hook function that is called after database operations are performed
     *
     * @param string $status The operation status ('new' or 'update')
     * @param string $table The table name being processed
     * @param int|string $id The record's ID
     * @param array $fieldArray The data array being processed
     * @param TYPO3CMSCoreDataHandlingDataHandler $dataHandler The DataHandler object
     */
    public function processDatamapAfterDatabaseOperations($status, $table, $id, &$fieldArray, TYPO3CMSCoreDataHandlingDataHandler $dataHandler)
    {
      # do something
    }
}

    Fifth, make sure your namespace is reflected in the extensions composer.json file:

    {
  "name": "vendor/mytheme",
  "description": "Your TYPO3 extension description.",
  "type": "typo3-cms-extension",
  "autoload": {
    "psr-4": {
      "Vendor\Mytheme\": "Classes/"
    }
  }
}

    Lastly, empty your caches.
