Return Value

The filtered value.

Examples

add_filter( 'woocommerce_product_add_to_cart_url', 'my_custom_add_to_cart_url', 10, 2 );

/**
 * Customizes the 'Add to Cart' URL for specific products.
 *
 * This function demonstrates how to modify the default 'Add to Cart' URL.
 * For example, it could be used to redirect users to a custom page or
 * to a direct purchase link if the product has special attributes.
 *
 * @param string $url The current 'Add to Cart' URL.
 * @param WC_Product $product The WC_Product object instance.
 * @return string The modified 'Add to Cart' URL.

	// redirect to a custom subscription management page instead of the default add-to-cart.
	if ( $product->is_type( 'subscription' ) && $product->get_meta( '_custom_subscription_link' ) ) {

	// Example: For a product that is out of stock, change the button to "View Details"
	// which links to the product's permalink.
	if ( ! $product->is_in_stock() ) {
		return get_permalink( $product->get_id() );
