Buy Now Button

Hello,

Please try to add the code below in the functions.php file in your child theme.

/* Create Buy Now Button dynamically after Add To Cart button */
function add_content_after_addtocart() {

    // get the current post/product ID
    $current_product_id = get_the_ID();

    // get the product based on the ID
    $product = wc_get_product( $current_product_id );

    // run only on simple products
    if( $product->is_type( 'simple' ) ){
        echo '<a href="https://example.com?add-to-cart='.$current_product_id.'" class="buy-now button">Purchase Now</a>';
    }
}
add_action( 'woocommerce_after_add_to_cart_button', 'add_content_after_addtocart' );

Replace https://example.com with the URL you want the button to link to and Purchase Now with the desired button text. This code will dynamically generate the “Buy Now” button with the specified link and text for simple products.

Best Regards.

Hello,

Please remove the previous code and try to add this code.

function sbw_wc_add_buy_now_button_single()
{
    global $product;
    $custom_button_text = 'Purchase Now'; // Custom button text
    printf(
        '<button id="sbw_wc-adding-button" type="submit" name="sbw-wc-buy-now" value="%d" class="single_add_to_cart_button buy_now_button button alt">%s</button>',
        $product->get_ID(),
        esc_html__( $custom_button_text, 'sbw-wc' )
    );
}

add_action( 'woocommerce_after_add_to_cart_button', 'sbw_wc_add_buy_now_button_single' );

/*** Handle for click on buy now ***/

function sbw_wc_handle_buy_now()
{
    if ( !isset( $_REQUEST['sbw-wc-buy-now'] ) )
    {
        return false;
    }

    WC()->cart->empty_cart();

    $product_id = absint( $_REQUEST['sbw-wc-buy-now'] );
    $quantity = absint( $_REQUEST['quantity'] );

    if ( isset( $_REQUEST['variation_id'] ) ) {
        $variation_id = absint( $_REQUEST['variation_id'] );
        WC()->cart->add_to_cart( $product_id, 1, $variation_id );
    } else {
        WC()->cart->add_to_cart( $product_id, $quantity );
    }

    // Redirect to custom URL
    $custom_url = 'https://example.com/custom-checkout'; // Custom URL
    wp_safe_redirect( $custom_url );
    exit;
}

add_action( 'wp_loaded', 'sbw_wc_handle_buy_now' );

Best Regards.

Hello,

You are adding the custom url. You can do it without custom code. Navigate to layouts > Edit Single Product layout with Elementor and add the button widget next to the add to cart and add the custom link.
