Error with Count() and member functions
18 March 2009 at 8:52pm
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;
}
