Magento加载具有所有属性的产品集合

Question

I need to iterate over some products and access custom attributes, my code is:

$collection = Mage::getModel('catalog/product')
    ->getCollection()
    ->addAttributeToSelect('*')
    ->addAttributeToFilter(array(array('attribute' => 'status', 'eq' => '1')))
    // more filters
    ->load();

then I have to:

foreach ($collection as $product) {
    // here I can't access custom attributes
    $product = Mage::getModel('catalog/product')->load($product->getId());
    // here I can access them
}

and my problem is when I have a lot of products my script spends a lot of time in foreach loop. Can I somehow speed this by loading collection with all attributes?

Answer 1

I suggest all your attributes should go in flat tables.

So do some attributes setting like searchable, available in front end listing.

Then do an indexing.

Now when you get product collection you will get needed attributes and then code from there.

Instead of a loop loading each product you need to load a collection of products.

Answer 2

If you are using flat-tables, you have to add your custom attributes to the flat index. You can add them in the config.xml of the according module. You can than skip the productload in the foreach which is probably causing the long processing time.

Answer 3

What you are doing is not a good practice and should be avoided. You may try this

foreach($collection->getItems() as $item){

     echo $item->getName(); //$item is product instance. you can use it
}

EDIT

In your question, you are doing a serious mistake and it should be avoided. That is what I am trying to point out through my answer.

See what you are doing here.

foreache($bigcollection as $singleone){
      $product = Mage::getModel('catalog/product')->load($id);
}

Basically you are loading a product inside a big for loop. It is a big mistake. Because if you do this, Magento need to do "extra fetching works" from database. Do not use that method . Through my solution, I showed you how to avoid loading a product inside a forloop. It is much reliable method.

If you dont want to use forloop, I think you need to edit your question and put that requirement there.

If you need to avoid for loop, you need to go for flat table concepts. That is the only one way that I know. Otherwise you cannot avoid a for each loop. :)
