php - Disable add to cart button based on WooCommerce product custom stock status

Question

Currently in woocommerce, add to cart button disabled, if the stock status is out of stock. I add new stock status with the label Discontinued product by using woocommerce_product_stock_status_options, now I am looking for a way to treat this product like it is out of stock.

Since I believe it is better to separate between a product that is not produced anymore and a product that produced and available in another store but it's not in stock.

Answer 1

You can use the following to disable add to cart button based on a custom stock status (where you will replace custom_status_slug by your custom status slug):

add_filter('woocommerce_is_purchasable', 'filter_is_purchasable_callback', 10, 2 );
add_filter('woocommerce_variation_is_purchasable', 'filter_is_purchasable_callback', 10, 2 );
function filter_is_purchasable_callback( $purchasable, $product ) {
    if ( $product->get_stock_status() === 'custom_status_slug' ) {
        return false;
    }

    return $purchasable;
}

Code goes in functions.php file of the active child theme (or active theme). Tested and works.
