By default, WooCommerce does not display “In stock” or the selected stock display format on the product page when the product’s Track stock quantity option is disabled.
Use the woocommerce_get_availability filter to display “In stock” when a product is in stock but WooCommerce is not tracking its quantity.
Add the snippet to your child theme’s functions.php file or use a code snippets plugin. Do not add custom code directly to a parent theme because a theme update will overwrite it.
Before using the snippet, replace your_prefix with a prefix unique to your child theme or custom plugin. Replace your-textdomain with its text domain.
if ( ! function_exists( 'your_prefix_show_in_stock_when_quantity_not_tracked' ) ) {
/**
* Displays "In stock" when a product is in stock but its quantity is not tracked.
*
* @param string[] $availability Product availability text and CSS class.
* @param WC_Product $product Product object.
* @return string[]

function your_prefix_show_in_stock_when_quantity_not_tracked( $availability, $product ) {
if ( ! $product->managing_stock() && $product->is_in_stock() ) {
$availability['availability'] = __( 'In stock', 'your-textdomain' );
}
return $availability;
}
}
add_filter( 'woocommerce_get_availability', 'your_prefix_show_in_stock_when_quantity_not_tracked', 10, 2 );This customization changes only the availability text. It does not enable stock management, change a product’s quantity, or mark an out-of-stock product as in stock.
