Question

I am having a problem with addAttributeToFilter() where it is not working as I expect.

$product = Mage::getModel('catalog/product');
...snip...
$simple_associated_collection = $product->getCollection()
  ->addAttributeToFilter('type_id', 'simple')
  ->addAttributeToFilter('sku',array('like'=>$configurable_product_sku.'_%'))
  ->load();

Passing in 4_% I expect to get

4_1
4_2

But I also get

42_1
420_1

The goal is to get a collection of simple products so that I can associate them with their configurable parent after an import.

How should I be using LIKE to get the same results I would in MySQL?

Answer 1

Magento was not at fault here, _ is a wildcard character.

I used Nick’s comment to echo the sql which was what I expected.

Fixed:

->addAttributeToFilter('sku',array('like'=>$configurable_product_sku.'\_%'))
