Prepare Joomla 5

• check and set options if empty in Plugin Bethico or BethicoAdmin:

  use Joomla\CMS\Plugin\CMSPlugin;
  use Joomla\Event\Event;
  
  class PlgSystemMyPlugin extends CMSPlugin
  {
      public function onExtensionBeforeSave($context, $table)
      {
          // 1. Check if we are saving component options (com_config)
          if ($context !== 'com_config.component') {
              return;
          }
  
          // 2. Identify which component's options were saved
          $componentName = $table->element; // e.g., 'com_content'
          
          if ($componentName === 'com_mycomponent') {
              // 3. React to the save (e.g., clear cache, log activity)
              $params = $table->params; // The new parameters
              // Your custom logic here
              // check whether we can modify $table, or we need to call $table->params->set('start_year', date('Y'));
          }
      }
  }

public function getOtherModelData()
    {
        // ... some logic ...

        // Get an instance of 'MyModel2' from the same component (e.g., 'com_mycomponent')
        // Assumes MyModel2 is in the Site directory if the current model is in Site
        $otherModel = Factory::getApplication()
            ->bootComponent('com_mycomponent')
            ->getMVCFactory()
            ->createModel('MyModel2', 'Site'); // Replace 'Site' with 'Administrator', 'Cli', or 'Api' if needed

        // Now you can call methods on the other model
        $items = $otherModel->getItems(); // Example method call

        return $items;
    }
