Hey guys.

I have a simple problem, but I have no idea on how to make this work.

I have the following PHP page...

Code:
<?php
class AjaxPage extends Api {
 
  // ...removed unrequired code ...
 
  public function get_calendar_eventsPage() {
    if (is_null($this->session->getSession(Api::SESSION_NAME_CALENDAR)))
      $this->session->setSession(Api::SESSION_NAME_CALENDAR, strftime('%F'));
   
    $events = new CalendarIterator(null, null);
   
    $this->smarty->assign('events', $events->getDataByDate($this->session->getSession(Api::SESSION_NAME_CALENDAR)));
    $this->smarty->display('ajax.calendar_events');
  }

  // ...removed unrequired code ...
 
}


The template code is....

Code:
{foreach from=$events item='event' name='evt'}
  <div id="event-{$event->id}" class="calendar-event" style="{calendar_position date=$event->created start_date=$event->start end_date=$event->finish this_hour=$event->this_hour} z-index: {$smarty.foreach.evt.iteration}; {$event->getCategoryObject()->style->div}">
    <span class="calendar-event-title" style=" {$event->getCategoryObject()->style->span}">{$event->subject|truncate:'38':'...':true}</span><br clear="all" />
    <p class="calendar-event-overview">{$event->description|nl2br}</p>
  </div>
{/foreach}


The Problem is...

Code:
{$event->getCategoryObject()->style->span}


The problem is when I get smarty to attempt to execute $event->getCategoryObject(), which is a method inside the
$event iterator object, this will create another iterator object instance returning another object. If you run this via the PHP, it works fine. just Smarty doesn't like the execution of chained objects :/

All I want is that Smarty allows the developer to implement iterator methods for object chaining.

Since 99% of my work is O.O.P object chaining is normally something that's used alot of the time.

Okay, so thanks for confirming object chaining does work. and Yes it does, however only when there is not fatal error inside the class im trying to return an instance of.

This is embarrassing for me so I wont elaborate on the small error causing this issue. But it works a charm.

Thanks again Smile
