Take the 2-minute tour ×  In a Magento Shop, I would like to be
able to classify products by some Classification mechanism
(example: Tag, Category, Related products or somthing else?)
Then I could build a block that will show all classification

this classification.    We already use Categories, so using this
classification mechanism would generate a list with many

all related tags require_once('app/Mage.php'); //Path to Magento
// Category 4 is called "Category with tags" $_categoryId = "4";
$_productCollection =
Mage::getModel('catalog/category')->load($_categoryId)
->addAttributeToFilter('status', 1)
->addAttributeToFilter('visibil
