here is my code.. when i am using getData() , it will give whole array..

 $model = Mage::getModel('warranty/warranty');

                    $war = $model->getCollection()
                                    ->addFieldToFilter('product_id',  array('eq' => $productId))

echo'<pre>';print_r($war->getData()); die;


    [0] => Array
            [id] => 9
            [product_id] => 554
            [warranty_period] => 2 month
            [price_in_warranty] => 500
            [price_out_warranty] => 24

    you can not call get id on collection object May 25, 2016 at 9:20

    if you have only one record in collection try as $war->getFirstItem()->getId() May 25, 2016 at 9:23

As you're dealing with a collection, you can't simply call:


If you want the id of the first item of your collection you can call:


If you want to get the ids of every items in your collection you can do:

foreach ($war as $item)
    echo $item->getId();

I think what you really wanted is this:


Because from your var dump, you can see that $war is a collection.

Of course, you can iterate through $war if you have multiple items in it.
