Magento – Display attribute set groups with product

After trying out again, messing up a lot and finally finding the correct answer, this works:

$entityTypeId = Mage::getModel('catalog/product')
                  ->getResource()
                  ->getEntityType()
                  ->getId(); //product entity type

$attributeSet = Mage::getModel('eav/entity_attribute_set')
                  ->setEntityTypeId($entityTypeId)
                  ->setAttributeSetName("test_set");

$attributeSet->validate();
$attributeSet->save();

$attributeSet->initFromSkeleton($entityTypeId)->save();

You need to save before you do initFromSekeleton(). Otherwise it just won't work.

Not much clear what you want to do really. Anyway this is the script to create a product attribute after you created the attribute set.

<?php

$th =  new Mage_Catalog_Model_Resource_Setup();  
$th->addAttribute(Mage_Catalog_Model_Product::ENTITY, 'your_custom_attribute_code', array(
            'group' => 'Prices', 
            'type' => 'text',
                        'attribute_set' =>  'Default', // Your custom Attribute set
            'backend' => '',
            'frontend' => '',
            'label' => 'My Custom Attribute',
            'input' => 'text',
            'global' => Mage_Catalog_Model_Resource_Eav_Attribute::SCOPE_GLOBAL,
            'visible' => true,
            'required' => false,
            'user_defined' => true,
            'default' => '1',
            'searchable' => false,
            'filterable' => true,
            'comparable' => false,
            'visible_on_front' => true,
            'visible_in_advanced_search' => true,
            'used_in_product_listing' => true,
            'unique' => false,
            'apply_to' => 'simple',  // Apply to simple product type
        ) );
