Product variations in WooCommerce are a great way to offer products that come in different sizes, colors, materials, etc. By offering variations, you can increase your sales and conversion rate, as customers are more likely to find the perfect product for them.
In order to add product variations programmatically in WooCommerce, you’ll need to first understand the structure of product variation data. Product variation data is stored as an array called the “variation data array.”
Each variation data array has the following format:
array(
'attributes' => array(
'attribute_pa_size' => 'small',
'attribute_pa_color' => 'red',
),
'regular_price' => '9.99',
'sale_price' => '',
'image' => array(
'src' => 'image_url',
'alt' => 'image_alt',
),
'weight' => '0.5',
'length' => '10',
'width' => '5',
'height' => '2',
'tax_class' => '',
'tax_status' => 'taxable',
'manage_stock' => 'yes',
'stock_quantity' => 10,
'backorders' => 'no',
'sku' => '',
'downloadable' => 'no',
'virtual' => 'yes',
'purchase_note' => '',
'shipping_class' => '',
'downloads' => array(),
'variation_description' => '',
'variation_id' => 0,
)You can use the WC_Product_Variable::update_variation_data() method to update or add new variations to a variable product. You can also use the WC_Product_Variable::get_available_variations() method to retrieve an array of all available variations for a variable product.
You can also use the WC_Product_Variable::add_variation() method to programmatically create new variations for a variable product.
$product = new WC_Product_Variable( $product_id );
$variation_id = $product->add_variation($variation_data);It’s also important to note that you need to have the attributes created in the admin area before you can add variations for them.
You will also need to properly set up and configure the attributes for your product in the WooCommerce settings before you can begin adding variations programmatically.
