Magento - Query for Product Options

Question

I want to write a controller that finds the different options for a given product (eg. Large, Medium, Small, Red, Blue etc...).

Can anyone show me the code I would w

Answer 1

Instead of getOptions() please try getCustomOptions() or getProductOptionsCollection() or getProductOptionsCollection()->load().

Edit
I tried this on a product I knew had options.

load($productId);
foreach ($product->getProductOptions() as $option) {
    print_r($option->debug());
}

And got something like this:

Array
(
    [option_id] => 37
    [product_id] => 8
    [type] => multidate
    [is_require] => 1
    [sku] => 
    [image_size_x] => 0
    [image_size_y] => 0
    [sort_order] => 1
    [default_title] => Dates
    [title] => Dates
)

However, getOptions() also worked for me so I don't know what's going on.

Post-edit
The confusion was one of semantics. A simple product can have "custom options", they allow creation of a few form fields which are recorded as part of the order. A configurable product uses "associated products" to create a form with conditional fields.

For example you might be selling socks that are large-green, small-green or large-blue - but no small-blue ones. With a simple product you would have a field for large/small and a field for blue/green - which allows the customer to select small-blue and that is wrong.

So to find the component parts of a configurable you might do something like this:

if ($product->isConfigurable()) {
    $configurable = $product->getTypeInstance();
    $childProducts = $product->getUsedProducts($product);
    foreach ($childProducts as $child) {
        // You have a $child now
    }
}

To find the equivalent of getOptions() you need this:

if ($product->isConfigurable()) {
    $configurable = $product->getTypeInstance();
    $attributes = $configurable->getConfigurableAttributes($product);
    // $attributes is a Mage_Catalog_Model_Resource_Eav_Mysql4_Product_Type_Configurable_Attribute_Collection
    foreach ($attributes as $attribute) {
        // $attribute is a Mage_Catalog_Model_Product_Type_Configurable_Attribute
        print $attribute->getLabel();
    }
}

Mage_Catalog_Model_Product_Type_Configurable_Attribute doesn't have much to reveal about itself.
