How to Create Variable Product Using the WC_Product_Variable() Class

Hello there,

I was trying to create a variable product using the API Method WC_Product_Variable Class in my store for that we are using set_attributes method for creating the attributes and set_variation_attribute for creating the variation in WooCommerce here is the code which we are using:

$products = new WC_Product_Variable();//$wcProductID
$products->set_name(‘Test Product Config For True color123’);
$products->set_sku(‘testconfig’);
$products->set_regular_price(200);
$products->set_sale_price(180);
$products->set_attributes($product_array);
$products->set_variation_attributes(array(
array(
‘sku’ => ‘codered’,
‘regular_price’ => ‘29.98’,
‘attributes’ => array(
array(
‘name’=>’color’,
‘options’=>’red’
)

)
),
array(
‘sku’ => ‘codeblack’,
‘regular_price’ => ‘29.98’,
‘attributes’ => array(
array(
‘name’=>’color’,
‘options’=>’black’
)
)
)
));
$result=$products->save();

By this a Variable Product gets created successfully, but without any attribute and variables. Please we need your help in creating the Variable Product in WooCommerce. Please response ASAP.
