Trigger for editing an event before saving

[spauldingsmails]

I was wondering if there is some way of intercepting a posted event in order to make changes to it prior to the event being saved? For example, we have heavily modified the add/edit event form but we have to use extensive amounts of client-side javascript to massage the data so that it matches the way saveicalevent::save stores the posted form. Even though we have used mootools to improve browser compatibility, there is still a concern that data may not be correctly manipulated and consequently, incorrect information will be stored.

If there is no currently existing method for manipulating the post, is there a possibility it could be incorporated into the icalevent::save and icalrepeat::save methods or saveicalevent::save; say, for example, via a trigger?

E.g.

Code: Select all

class SaveIcalEvent {
   
   function save($array, &$queryModel, $rrule){
      
      $cfg = & JEVConfig::getInstance();
      $db   =& JFactory::getDBO();
      $user =& JFactory::getUser();

               $dispatcher     =& JDispatcher::getInstance();
               JPluginHelper::importPlugin("jevents");
               $res = $dispatcher->trigger( 'onBeforeSaveEvent' , $array, $rrule);
      ...
   }

No problem - I can add this to the next release.

Thanks, that would be great.

May I extend my thoughts to the following;

1. An event that triggers before the event save (AdminIcaleventController::save);

E.g.

Code: Select all

        function save(){
                if (!JEVHelper::isEventCreator()){
                        JError::raiseError( 403, JText::_("ALERTNOTAUTH") );
                }

                // clean out the cache
                $cache = &JFactory::getCache('com_jevents');
                $cache->clean(JEV_COM_COMPONENT);

                // JREQUEST_ALLOWHTML requires at least Joomla 1.5 svn9979 (past 1.5 stable)
                $array = JRequest::get('request', JREQUEST_ALLOWHTML);

                $dispatcher =& JDispatcher::getInstance();
                JPluginHelper::importPlugin("jevents");
                $res = $dispatcher->trigger("onBeforeSaveIcalEvent", array(&$array));

                $rrule = SaveIcalEvent::generateRRule($array);


2. An event that triggers before the repeat save (AdminIcalrepeatController::save);

E.g.

Code: Select all

        function save(){
                ...
                $data["X-COLOR"]        =  JRequest::getVar(  "color","");

                $dispatcher =& JDispatcher::getInstance();
                JPluginHelper::importPlugin("jevents");
                $res = $dispatcher->trigger("onBeforeSaveIcalRepeat", array(&$data));

                $detail = iCalEventDetail::iCalEventDetailFromData($data);

                // if we already havea unique event detail then edit this one!
                if ($eventdetailid != $rpt->eventdetail_id){
                        $detail->evdet_id = $rpt->eventdetail_id;
                }
               
                ...
      }


The benefit above being that one can take alternative actions based on what is being updated.
