Need product count in magento - magento

Question

I need to show product count behalf of brand/manufacturer
foreach($children as $subCat)
{
$brand_name = $subCat->getName();
$products = Mage::getModel('catalog/product')->getCollection();
$products = $products->addAttributeToFilter('manufacturer',$brand_name);
echo $products->count();
}

Answer 1

If brand is dropdowon or Multi Select attribute then you cannot filter by BrandName(That means option name).
You can filter by Brand Option id:
$products = Mage::getModel('catalog/product')->getCollection();
$products = $products->addAttributeToFilter('manufacturer',$brand_id);
if you are using Catalog Product flat then you need to Enable manufacturer attribute to Product Listing from Manage attribute >select manufacturer attribute enable attibute to product listing
According to you comment if you want to Product Collection by two catgories then try below
$_productCollection = Mage::getModel('catalog/product')
->getCollection()
->joinField('category_id', 'catalog/category_product', 'category_id', 'product_id = entity_id', null, 'left')
->addAttributeToSelect('*')
->addAttributeToFilter('category_id', array(
array('finset' => $catid),
array('finset' => $parent_Cat_id))
)
->addAttributeToSort('created_at', 'desc');

Or get all option list of Manufacture attribute then you can get it option id by below code
$attribute_code = "manufacture";
$attribute_details = Mage::getSingleton("eav/config")->getAttribute("catalog_product", $attribute_code);
$options = $attribute_details->getSource()->getAllOptions(false);
foreach($options as $option){
// print_r($option) and find all the elements e
cho $option["value"];
echo $option["label"];
}
