magento limiting number of returned items in product collection call

Question

Im trying to limit the number of returned results manually in a copy of the list.phtml template, but its turning out to be alot harder than I anticipated.

Ive tried man

Answer 1

unfortunately it doesn't work because in the _getProductCollection() method the Collection has been already initialized with a page size.

A more flexible solution could be that of observing the catalog_product_collection_load_before event which, as the name suggests, is dispatched before the collection is loaded.

Here follows an example (assuming to write a yourmodule extension under yourpackage):

STEP 1: Define your observer in config.xml

in the global section of your config.xml extension file insert something like:

  
    
      
        singleton
        yourpackage_yourmodule/catalog_observer
        limitPageSize
      
    
  
    

STEP 2: Define your Observer class under the Model\Catalog folder:

getEvent();
    $collection = $event->getCollection();
    $collection->setPageSize(3);
    return $this;
  }
}

Hope it helps. Sincerely, Alessandro Ronchi
