Is there a way to duplicate all the variations and their values of one product in WooCommerce to all the other products in a given category?

I have over 400 products in my WooComerce store, and they all were done as a simple product. The problem is that now I have to add variations to all the products (to satify a shipping plugin) and it will take me forever if I have to do this manually for each product.

I have setup one of my product with all the variations and values needed to be duplicated to the other products of the same category.

I tried piecing together a simple plugin to do this based on TSCAmerica.com answer.

Below is the complete plugin code for anyone to try out and see if it is working for them or where it needs to be fixed:

add_action('admin_menu', 'wcvc_create_menu');

function wcvc_create_menu() {

    //create new top-level menu
    add_menu_page('WC Copy Variations Settings', 'Copy Variations', 'administrator', __FILE__, 'wcvc_settings_page' , plugins_url('/images/icon.png', __FILE__) );

    //call register settings function
    add_action( 'admin_init', 'register_wcvc_settings' );
}


function register_wcvc_settings() {
    //register our settings

        register_setting( 'wcvc-settings-group', 'wcvc_status' );
    
}

function wcvc_settings_page() {

// Trigger wcv copy
$wcvc_status = get_option('wcvc_status');
    if(str_contains($wcvc_status, 'yes')) {

Enter the source ID and the target ID and hit save, then it will dispaly any variations in the source and target products. If you want to perform the copy, enter ‘yes’ in the last field and hit save again.

The issue I am having is that it is not saving the new variations to the target product. I VAR DUMPED every possible variable and the data is there in the right places. After the save command, the ID does increment for each new variation, however, either the save() is not working properly for some reason or WooComerce is deleting the saved variation immediately after the save.

What am I missing or doing wrong?

After Moshe Gross's answer, I added a cleanup routine to the perform_wvc_copy function, removing any existing product variations before the copy.

The fixed function:

function perform_wcv_copy() {
    global $options;
    $source_product_id = get_option('source_product_id');
    $target_product_id = get_option('target_product_id');

    $source_product = wc_get_product($source_product_id);
    $target_product = wc_get_product($target_product_id);

    // Check if source and target products have variations
    if ($source_product->is_type('variable') && $target_product->is_type('variable')) {

        // Get the variations of the target product
        $t_variations = $target_product->get_children();

        // Delete existing product variations
        foreach ($t_variations as $t_variation_id) {
            $t_variation = wc_get_product($t_variation_id);
            $t_variation->delete( true );
        }
    }        

    // Check if the source product has variations
    if ($source_product->is_type('variable')) {
        if (!$target_product->is_type('variable')) {
            /* Update target parent */
            $target_product = wc_get_product($target_product_id);
            $target_product->set_attributes($source_product->get_attributes());
            $target_product->save();
            wp_set_object_terms( $target_product_id, 'variable', 'product_type' );
        }
    
        // Get the variations of the source product
        $variations = $source_product->get_children();

        foreach ($variations as $variation_id) {
            $variation = wc_get_product($variation_id);

            // Create a new variation for the target product
            $new_variation = new WC_Product_Variation();
            $new_variation->set_parent_id($target_product_id);
            
            // Set attributes and other settings from the source variation
            $new_variation->set_attributes($variation->get_attributes());
            $new_variation->set_regular_price($variation->get_regular_price());
            $new_variation->set_sale_price($variation->get_sale_price());
            $new_variation->set_weight($variation->get_weight());
            $new_variation->set_length($variation->get_length());
            $new_variation->set_height($variation->get_height());
            $new_variation->set_width($variation->get_width());
            
            // Save the new variation
            $new_variation->save();
        }
    }
    update_option( 'wcvc_status', 'done' );
}

If there's anything else, please provide a comment or answer.

(Edit)

There’s two things missing from the code above

You’re not adding the attribute to the parent product, and the product is still set as a simple (not variable) product

you can add a few lines to fix this

function perform_wcv_copy() {
    global $options;
    $source_product_id = get_option('source_product_id');
    $target_product_id = get_option('target_product_id');

    $source_product = wc_get_product($source_product_id);

    // Check if the source product has variations
    if ($source_product->is_type('variable')) {
        /* Update target parent */
        $target_product = wc_get_product($target_product_id);
        $target_product->set_attributes($source_product->get_attributes());
        $target_product->save();
        wp_set_object_terms( $target_product_id, 'variable', 'product_type' );
        
        // Get the variations of the source product
        $variations = $source_product->get_children();

        foreach ($variations as $variation_id) {
            $variation = wc_get_product($variation_id);

            // Create a new variation for the target product
            $new_variation = new WC_Product_Variation();
            $new_variation->set_parent_id($target_product_id);
            
            // Set attributes and other settings from the source variation
            $new_variation->set_attributes($variation->get_attributes());
            $new_variation->set_regular_price($variation->get_regular_price());
            $new_variation->set_sale_price($variation->get_sale_price());
            $new_variation->set_weight($variation->get_weight());
            $new_variation->set_length($variation->get_length());
            $new_variation->set_height($variation->get_height());
            $new_variation->set_width($variation->get_width());
            
            // Save the new variation
            $new_variation->save();
        }
    }
    update_option( 'wcvc_status', 'done' );
}

P.s. if you run this for the same id multiple times (and you might have done already even if the variations didn’t show) you’ll have multiple of the same variations
