Question

I’m trying to add some items to a custom created collection. Reading Alan Storm varien data collection and this SO question I got to a couple of different options.

Here is one option using Varien_Data_Collection:

    $myResultCollection = new Varien_Data_Collection();
    $mybanner = new Varien_Object();
    foreach($myBannersCollection as $banner){
        $mybanner = $banner;
        $search_text = explode(",", $banner->getsearch_text());
        foreach ($search_text as $txt){
            if (stripos($currentProdName,$txt) !== false) {
                $myResultCollection->addItem($mybanner);
            }
        }
    }

This code throws the following error:

Item (Dts_Banners_Model_Bannersadmin) with the same id "10" already exist

And here is another variation of the code, using my custom collection from a model I currently use:

    $myResultCollection = Mage::getModel('banners/bannersadmin');
    foreach($myBannersCollection as $banner){
        $search_text = explode(",", $banner->getsearch_text());
        foreach ($search_text as $txt){
            if (stripos($currentProdName,$txt) !== false) {
                $myResultCollection->addItem($banner);
            }
        }
    }

But this one shows the following error (not showing everything, is way to long):

Invalid method Dts_Banners_Model_Bannersadmin::addItem(Array
(
    [0] => Dts_Banners_Model_Bannersadmin Object
        (
            [_eventPrefix:protected] => core_abstract
            [_eventObject:protected] => object
            [_resourceName:protected] => banners/bannersadmin
            [_resource:protected] => 
            [_resourceCollectionName:protected] => banners/bannersadmin_collection
            [_cacheTag:protected] => 
            [_dataSaveAllowed:protected] => 1
            [_isObjectNew:protected] => 
            .......

What I’m doing wrong?

Answer 1

Problem #1: Items being added to a Varien_Data_Collection instance need to have distinct IDs in the context of the collection.

Problem #2: Dts_Banners_Model_Bannersadmin is not an instance of Varien_Data_Collection.
