I’m building a site where WooCommerce Variable products (with Products Variations) are inserted programmatically. I have followed this tutorial successfully:
Insert WooCommerce Products & Variations Programmatically
I need just something that is missing:
How to set variations default attributes values for a variable product?
Is it possible?

Answer
1). You will need to insert in your json
data for each variable product this piece of array like:
"variations_default_attributes":
[
{
"size" : "Medium",
"color" : "Blue"
}
]
Or
"variations_default_attributes":
{
"size" : "Medium",
"color" : "Blue"
}
This array is made with the attribute short slug (without ‘pa_
‘) and the default term name values.
2). Then the dedicated function:
function insert_variations_default_attributes( $post_id, $products_data ){
foreach( $products_data as $attribute => $value )
$variations_default_attributes['pa_'.$attribute] = get_term_by( 'name', $value, 'pa_'.$attribute )->slug;
// Save the variation default attributes to variable product meta data
update_post_meta( $post_id, '_default_attributes', $variations_default_attributes );
}
3). You will need to trigger this function adding one line at the end:
function insert_product ($product_data)
{
$post = array( // Set up the basic post data to insert for our product
'post_author' => 1,
'post_content' => $product_data['description'],
'post_status' => 'publish',
'post_title' => $product_data['name'],
'post_parent' => '',
'post_type' => 'product'
);
$post_id = wp_insert_post($post); // Insert the post returning the new post id
if (!$post_id) // If there is no post id something has gone wrong so don't proceed
{
return false;
}
update_post_meta($post_id, '_sku', $product_data['sku']); // Set its SKU
update_post_meta( $post_id,'_visibility','visible'); // Set the product to visible, if not it won't show on the front end
wp_set_object_terms($post_id, $product_data['categories'], 'product_cat'); // Set up its categories
wp_set_object_terms($post_id, 'variable', 'product_type'); // Set it to a variable product type
insert_product_attributes($post_id, $product_data['available_attributes'], $product_data['variations']); // Add attributes passing the new post id, attributes & variations
insert_product_variations($post_id, $product_data['variations']); // Insert variations passing the new post id & variations
## Insert variations default attributes passing the new post id & variations_default_attributes
insert_variations_default_attributes( $post_id, $products_data['variations_default_attributes'] );
}
Code goes in function.php file of your active child theme (or theme) or also in any plugin file.
This code is tested and works.
