woocommerce_add_to_cart_form_action

Filters the action URL for the add to cart form before it's submitted.

add_filter( 'woocommerce_add_to_cart_form_action', $callback, 10, 1 );

Description

Usage

add_filter( 'woocommerce_add_to_cart_form_action', 'your_function_name', 10, 1 );

Parameters

$product (mixed)
This parameter represents the WooCommerce product object being added to the cart.

Return Value

The filtered value.

Examples

/**
 * Filters the action URL for the add to cart form to a custom endpoint for specific products.
 *
 * @param string $url    The default add to cart form action URL.
 * @param WC_Product $product The product object.
 * @return string The modified add to cart form action URL.
 */
add_filter( 'woocommerce_add_to_cart_form_action', function( $url, $product ) {
    // Check if the product has a custom meta key indicating it's a special type.
    if ( $product->get_meta( '_is_special_order_product' ) === 'yes' ) {
        // If it's a special order product, redirect to a custom endpoint for processing.
        // This assumes you have a custom endpoint set up at '/special-order-processing/'.
        // You would need to handle the logic for this endpoint separately.
        return home_url( '/special-order-processing/' );
    }

    // For all other products, return the original URL.
    return $url;
}, 10, 2 ); // Priority 10, accepts 2 arguments.
