Get the Product Variation related to default attri

问题:

I would like to display the default product attributes form value and it's regular price in my front end template file.

The var_dump below shows options in an array. I Need to get the [default_attributes] values.

<?php 
    global $product;
    echo var_dump( $product );
// Need to get the [default_attributes] values


?>

To get the default attributes for a variable product you can use WC_Product method get_default_attributes() this way:

<?php 
    global $product;

    if( $product->is_type('variable') ){
        $default_attributes = $product->get_default_attributes();

        // Testing raw output
        var_dump($default_attributes);
    }
?>

Now to find out which is the corresponding product variation for this "defaults" attributes, is a little more complicated:

<?php 
    global $product;

    if( $product->is_type('variable') ){
        $default_attributes = $product->get_default_attributes();
        foreach($product->get_available_variations() as $variation_values ){
            foreach($variation_values['attributes'] as $key => $attribute_value ){
                $attribute_name = str_replace( 'attribute_', '', $key );
                $default_value = $product->get_variation_default_attribute($attribute_name);
                if( $default_value == $attribute_value ){
                    $is_default_variation = true;
                } else {
                    $is_default_variation = false;
                    break; // Stop this loop to start next main lopp
                }
            }
            if( $is_default_variation ){
                $variation_id = $variation_values['variation_id'];
                break; // Stop the main loop
            }
        }

        // Now we get the default variation data
        if( $is_default_variation ){
            // Raw output of available "default" variation details data
            echo '<pre>'; print_r($variation_values); echo '</pre>';

            // Get the "default" WC_Product_Variation object to use available methods
            $default_variation = wc_get_product($variation_id);

            // Get The active price
            $price = $default_variation->get_price(); 
        }
    }
?>

This is tested and works.
