Well, a survey is not complete if a quota is fulfilled. So a new event is needed.

This quota system need some rewrite, and move to a specific controllers and/or helpers.
I never know if it's best to use helper or controller ;).

Did a core system (not a plugin) can use plugin event ? Here : we can use beforeSurveyPage (i think) for test quota/set token to Q/ show the page to the user.

I found an error with quota: i added the same question with multiple answers

example: register for event 1) morning, 2) afternoon, 3) all day
I want to count all in the morning so i need to add 1 and 3
and for afternoon i count 2 and 3
This does not show correct in the quota screen. I also noticed that checking during survey is done in fontend_helper -> checkQuota and for admin display on common_helper -> getquotacompletedcount

These two should be merged into one, preferrably on one of the models (survey or quota, i don't really care)

(No time to investigate further, and no git at hand... this is my edited common_helper:

/**

• Returns the number of answers matching the quota
• @param int $iSurveyId - Survey identification number
• @param int $quotaid - quota id for which you want to compute the completed field

• @return mixed - Integer of matching entries in the result DB or 'N/A'
  */
  function getQuotaCompletedCount($iSurveyId, $quotaid)
  {
  $result = "N/A";
  if(!tableExists("survey{$iSurveyId}")) // Yii::app()->db->schema->getTable('{{survey' . $iSurveyId . '}}' are not updated even after Yii::app()->db->schema->refresh();
  return $result;
  $quota_info = getQuotaInformation($iSurveyId, Survey::model()->findByPk($iSurveyId)->language, $quotaid);
  $quota = $quotainfo[0];
  if (Yii::app()->db->schema->getTable('{{survey' . $iSurveyId . '}}') &&
  count($quota['members']) > 0)
  {
  // Keep a list of fields for easy reference
  $fields_list = array();

  // Construct an array of value for each $quota['members']['fieldnames']
  $fields_query = array();
  
  foreach ($quota['members'] as $member)
  {
      foreach ($member['fieldnames'] as $fieldname)
      {
          if (!in_array($fieldname, $fields_list))
              $fields_list[] = $fieldname;
  
          $fields_query[$fieldname][] = $member['value'];
      }
  
  }
  
  $criteria = new CDbCriteria;
  
  foreach ($fields_list as $fieldname) {
       $criteria->addInCondition(Yii::app()->db->quoteColumnName($fieldname), $fields_query[$fieldname]);
  }
  $criteria->mergeWith(array('condition'=>"submitdate IS NOT NULL"));
  $result = SurveyDynamic::model($iSurveyId)->count($criteria);

  }

  return $result;
  }

Seems beter here, and surely rigth ... not same function for same behaviour ... :)

Rewriting checkQuota, using getQuotaCompletedCount then we can update getQuotaCompletedCount with better count

@mdekker : You can report the second problem with quota on multi question type ?

@mdekker : with some inspiration from your fix : http://bugs.limesurvey.org/plugin.php?page=Source/view&id=14308

Some other thing to do in quota
