I have the following function in a page controller:

   function newCount() {
      $outfits = DataObject::get('OutfitPage');
      $outfitCount = $outfits->Count() - 1;
      return $outfitCount ? $outfitCount : 0;
   }

and it's giving the following error:

Fatal error: Call to a member function Count() on a non-object in /home/robynmat/public_html/ss/mysite/code/OutfitHolder.php on line 41

Any idea of the possible reasons for this? As far as I can see it was working fine that code until a larger amount of objects (OutfitPage) were created (i.e. around 30 or so). Or maybe something else changed but I can't think of what.

Help/ideas would be much appreciated :)

Cheers

You should check for the existance of the object before calling Count() on it. It's also possible to optimise your code further as well.

Here's an example:

function newCount() {
   $outfits = DataObject::get('OutfitPage');
   return ($outfits) ? ($outfits->Count() - 1) : 0;
}
