    Error with Count() and member functions Link to this post

    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;
    }
