To automatically add WooCommerce attributes in Dokan, you can achieve this by programmatically associating attributes with products when they are created or updated by vendors. Here’s how you can do it:

Steps to Automatically Add WooCommerce Attributes in Dokan

1. Use the `woocommerce_new_product` or `woocommerce_update_product` Hook

These hooks are triggered whenever a product is created or updated.

2. Add Attributes Programmatically

Use WooCommerce functions to assign attributes to the product.

Add the following code to your theme’s functions.php file or a custom plugin:

function add_woocommerce_attributes_to_dokan_products( $product_id ) {
    // Get the product object
    $product = wc_get_product( $product_id );

    // Check if the product is being added or updated by a Dokan vendor
    if ( dokan_is_seller_product( $product_id ) ) {

        // Define the attributes
        $attributes = array(
            'pa_color' => array( 'red', 'blue', 'green' ), // Replace 'pa_color' with your attribute slug and values
            'pa_size'  => array( 'small', 'medium', 'large' ), // Replace 'pa_size' with your attribute slug and values
        );

        // Prepare the product attributes
        $product_attributes = array();

        foreach ( $attributes as $attribute_slug => $terms ) {
            // Get the attribute ID and check if it exists
            $attribute_id = wc_attribute_taxonomy_id_by_name( $attribute_slug );
            if ( ! $attribute_id ) {
                continue; // Skip if attribute does not exist
            }

            $product_attributes[ $attribute_slug ] = array(
                'name'         => 'pa_' . $attribute_slug,
                'value'        => implode( '|', $terms ),
                'position'     => 0,
                'is_visible'   => 1,
                'is_variation' => 1,
                'is_taxonomy'  => 1,
            );

            // Add terms to the attribute
            foreach ( $terms as $term ) {
                if ( ! term_exists( $term, 'pa_' . $attribute_slug ) ) {
                    wp_insert_term( $term, 'pa_' . $attribute_slug );
                }
            }
        }

        // Set the attributes for the product
        $product->set_attributes( $product_attributes );
        $product->save();
    }
}
add_action( 'woocommerce_new_product', 'add_woocommerce_attributes_to_dokan_products' );
add_action( 'woocommerce_update_product', 'add_woocommerce_attributes_to_dokan_products' );

Explanation of the Code

Hook into Product Creation/Update:
- woocommerce_new_product triggers when a new product is created.
- woocommerce_update_product triggers when an existing product is updated.
Check Vendor’s Product:
- dokan_is_seller_product() ensures the code runs only for products created or updated by Dokan vendors.
Define and Add Attributes:
- The $attributes array contains attribute slugs and terms.
- wc_attribute_taxonomy_id_by_name() checks if the attribute exists.
- wp_insert_term() adds terms to the attribute taxonomy.
Set Product Attributes:
- Attributes are added to the product using $product->set_attributes().
Save the Product:
- save() ensures the changes are saved.

Additional Notes

Replace pa_color and pa_size with your custom attribute slugs.
Ensure the attributes are already created in WooCommerce (from Products > Attributes).
Test the code in a staging environment before deploying to a live site.
