How can I sort products by stock status in WooCommerce for different user roles

php
add_filter('woocommerce_get_catalog_ordering_args', 'custom_sort_by_stock_status', 9999);
function custom_sort_by_stock_status($args) {
    // Check if the current user is an administrator
    if (current_user_can('manage_woocommerce')) {
        $args['orderby'] = 'meta_value_num'; // Sort by numeric meta value
        $args['meta_key'] = '_stock'; // Use stock quantity as meta key
        $args['order'] = 'DESC'; // Set order to descending (highest stock first)
    } else {
        $args['orderby'] = 'meta_value'; // Sort by meta value
        $args['meta_key'] = '_stock_status'; // Use stock status as meta key
        $args['order'] = 'ASC'; // Set order to ascending (in stock first)
    }
    return $args;
}

Here's how it works:

1. The `woocommerce_get_catalog_ordering_args` filter is used to modify the sorting arguments.

2. Inside the `custom_sort_by_stock_status` function, we check the current user's capabilities using `current_user_can('manage_woocommerce')`.

3. If the current user is an administrator (has the `manage_woocommerce` capability), we set the following sorting arguments:
- `orderby` is set to `'meta_value_num'` to sort by numeric meta value.
- `meta_key` is set to `'_stock'` to use the actual stock quantity as the sorting criteria.
- `order` is set to `'DESC'` to display products with the highest stock quantity first.

4. If the current user is not an administrator, we set the following sorting arguments:
- `orderby` is set to `'meta_value'` to sort by meta value.
- `meta_key` is set to `'_stock_status'` to use the stock status as the sorting criteria.
- `order` is set to `'ASC'` to display in-stock products first, followed by out-of-stock products.

5. The modified `$args` array is returned to apply the custom sorting.

This code will sort products differently for administrators and non-administrators:

- Administrators will see products sorted by stock quantity in descending order (highest stock first).
- Non-administrators (e.g., shop managers, customers) will see products sorted by stock status in ascending order (in-stock first, out-of-stock last).

To implement this, add the code snippet to your theme's `functions.php` file or a custom plugin.

By using the `current_user_can` function, you can customize the sorting behavior based on the user's role, providing a more tailored experience for administrators and other user roles in your WooCommerce store.
