Impressions

The progress bar widget included in an example data container array

Installation

1. Install via composer: composer require heimrichhannot/contao-progress-bar-widget-bundle.

Usage

1. Create the field in the desired data container array (DCA) as usual:

   'importProgress'                 => [
       'inputType' => 'huhProgressBar',
       'eval' => [
           // an introduction text for the widget (mandatory)
           'description' => $GLOBALS['TL_LANG']['tl_entity_import_config']['reference']['importProgressDescription'],
           // only show the progress bar but not the numbers below (optional, default false)
           'hideNumbers' => false,
           // hide skipped items from the numbers section (optional, default false)
           'hideSkippedItems' => false
       ]
   ],

2. The progress is passed via an event listener for the event LoadProgressEvent. Register an event listener (or subscriber) as usual in symfony:

   use HeimrichHannot\ProgressBarWidgetBundle\Event\LoadProgressEvent;
   use HeimrichHannot\ProgressBarWidgetBundle\Widget\ProgressBar;
   use Terminal42\ServiceAnnotationBundle\Annotation\ServiceTag;
   
   /**
    * @ServiceTag("kernel.event_listener", event="huh.progress_bar_widget.event.load_progress")
    */
   class LoadProgressListener
   {
       public function __invoke(LoadProgressEvent $event) {
           if (null === ($record = MyModel::findByPk($event->getId()))) {
               return;
           }
   
           // map the record's state field to the progress bar's expectations
           // of course you can decide yourself in which cases you'd like to pass which state
           switch ($record->state) {
               case 'success':
                   $state = ProgressBar::STATE_SUCCESS;
                   $class = 'tl_confirm';
                   break;
               case 'error':
                   $state = ProgressBar::STATE_FAILED;
                   $class = 'tl_error';
                   break;
               default:
                   $state = ProgressBar::STATE_IN_PROGRESS;
                   $class = '';
           }
   
           $data = [
               'state' => $state,
               'currentProgress' => $record->importProgressCurrent, // field name depends on your dca
               'totalCount' => $record->importProgressTotal, // field name depends on your dca
               'skippedCount' => $record->importProgressSkipped, // field name depends on your dca
           ];
   
           // add messages if some are available
           if ($record->importProgressResult) {
               $data['messages'] = [[
                   'class' => $class,
                   'text' => str_replace("\n", '<br>', $record->importProgressResult),
               ]];
           }
       }
   }
