Magento: Add / Delete / View Custom Options of Product Programmatically

Custom options on Magento products are designed to make simple products function like a configurable product with different choosing options like color, size, etc. before purchasing the product.

In this tutorial, I present the code to create/add, view, and delete custom options of a product in Magento.

ADD CUSTOM OPTIONS

In the following example code, I am adding custom option with title ‘Color’ and I have added two values to it ‘Red’ and ‘Gold’.

Mage::app()->setCurrentStore(Mage_Core_Model_App::ADMIN_STORE_ID);

$productId = YOUR_PRODUCT_ID;
$product = Mage::getModel('catalog/product')->load($productId);

$options = array(
                'title' => 'Color',
                'type' => 'drop_down',
                'is_required' => 1,
                'sort_order' => 0,
                'values' => array(
                                array(
                                    'title' => 'Red',
                                    'price' => 10.50,
                                    'price_type' => 'fixed',
                                    'sku' => '',
                                    'sort_order' => 0,
                                ),
                                array(
                                    'title' => 'Gold',
                                    'price' => 0,
                                    'price_type' => 'percent',
                                    'sku' => 'test-product-sku',
                                    'sort_order' => 0,
                                )
                            )
            );

$product->setProductOptions(array($options));
$product->setCanSaveCustomOptions(true);
$product->save();

You can now see the following custom options when you edit your product in admin:

DISPLAY CUSTOM OPTIONS OF A PRODUCT

$productId = YOUR_PRODUCT_ID;
$product = Mage::getModel('catalog/product')->load($productId);

$customOptions = $product->getOptions();

foreach ($customOptions as $option) {
    //print_r($option->getData());
    
    echo "<div style='background-color: #eeeeee; border: 1px solid #666666; margin-bottom: 5px; padding: 5px'>";
    
    echo "<strong>Option</strong><br />";
    echo "ID: " . $option->getOptionId() . '<br />';
    echo "Title: " . $option->getTitle() . '<br />';
    echo "Type: " . $option->getType() . '<br />';
    echo "Is Required: " . $option->getIsRequired() . '<br />';
    echo "Sort Order: " . $option->getSortOrder() . '<br />';
    echo "<br />";
    
    echo "<strong>Values</strong><br />";
    $values = $option->getValues();
    foreach($values as $value) {
        //print_r($value->getData());
        
        echo "Value ID: " . $value->getOptionTypeId() . '<br />';
        echo "Option ID: " . $value->getOptionId() . '<br />';
        echo "Title: " . $value->getTitle() . '<br />';
        echo "Price: " . $value->getPrice() . '<br />';
        echo "Price Type: " . $value->getPriceType() . '<br />';
        echo "SKU: " . $option->getSku() . '<br />';
        echo "Sort Order: " . $option->getSortOrder() . '<br />';
        echo "<br />";
    }
    echo "</div>";
}

DELETE CUSTOM OPTIONS OF A PRODUCT

$productId = YOUR_PRODUCT_ID;
$product = Mage::getModel('catalog/product')->load($productId);

$customOptions = $product->getOptions();

foreach ($customOptions as $option) {
    $option->delete();
}

$product->setHasOptions(0);
$product->save();

Hope it helps. Thanks.
