What hooks can I use to sort products by stock status in WooCommerce

1. `woocommerce_get_catalog_ordering_args`

This filter allows you to modify the arguments used for sorting products on the shop page. You can set it to sort by the `_stock_status` meta key.

Example Code:

php
add_filter('woocommerce_get_catalog_ordering_args', 'custom_sort_by_stock_status', 9999);
function custom_sort_by_stock_status($args) {
    $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
    return $args;
}

2. `woocommerce_catalog_orderby`

This filter allows you to add a custom sorting option to the WooCommerce sorting dropdown.

Example Code:

php
add_filter('woocommerce_catalog_orderby', 'add_stock_sorting_option');
function add_stock_sorting_option($options) {
    $options['in-stock'] = __('Show In Stock Products First', 'your-text-domain');
    return $options;
}

add_filter('woocommerce_get_catalog_ordering_args', 'sort_products_by_stock_order');
function sort_products_by_stock_order($args) {
    if (isset($_GET['orderby']) && 'in-stock' === $_GET['orderby']) {
        $args['meta_key'] = '_stock_status'; // Use stock status as meta key
        $args['orderby'] = array('meta_value' => 'ASC'); // Show in-stock products first
    }
    return $args;
}

Implementation Steps

1. Access Your Theme's Functions File: - Go to your WordPress dashboard.
- Navigate to Appearance > Theme Editor.
- Select the `functions.php` file.

2. Insert the Code: - Copy and paste the above code snippets into your `functions.php` file.

3. Save Changes: - Save the file and check your shop page to see the sorting in effect.

Notes

- Ensure that your products have stock management enabled to utilize the `_stock_status` meta key effectively.
- You can modify the order from ascending (`ASC`) to descending (`DESC`) based on your preference.
- Always back up your `functions.php` file before making changes to avoid any potential issues.

By using these hooks, you can effectively sort WooCommerce products by their stock status, enhancing the shopping experience for your customers.
