Change product name for generated variable products in WooCommerce

TL;DR version

How do I change the name that is automatically generated for variable products?

---

Detailed version

The product variations all get names based on the variable attributes they generate from.

Example

Let’s say that there’s the varible product: Vase. Vase has the attribute: Condition, with values:

• ‘New’
• ‘Refurbished’
• ‘Used’.

So if I do this (get and output all variation names):

$vase = wc_get_product( $vase_product_id );
$variation_ids = $vase->get_children();
if( !empty( $variation_ids ) ):
    foreach( $variation_ids as $v_id ):
        $variation = wc_get_product( $v_id );
        echo '<pre>';
        print_r($variation->get_name());
        echo '</pre>';
    endforeach; // foreach( $variations as $item ):
endif; // if ( !empty( $variations ) )

It will output:

Vase - New
Vase - Refurbished
Vase - Used

How do I change this, so it becomes:

Vase - New condition
Vase - Refurbished condition
Vase - Used condition

… So adding the attribute-name after the variation-value.

Answer

$vase        = wc_get_product( $vase_product_id );
$parent_name = $vase->get_name();

$variation_ids = $vase->get_children();
if ( !empty( $variation_ids ) ):
    foreach ( $variation_ids as $v_id ):
        $variation = wc_get_product( $v_id );
        echo '<pre>';
        print_r( $parent_name . ' - ' . $variation->get_attribute_summary() );
        echo '</pre>';
    endforeach; // foreach( $variations as $item ):
endif;
