Change payment method title for specific products in WooCommerce checkout

Question

I'm trying that, when a specific product is in the checkout, the title of the payment method changes from; for example: "Payment by card" to "Payment in parts", is it possible?

I have tried with jquery:

jQuery(function($){
    if ( $('#payment-fractional-payment').length ){
        $("label[for='payment_method_redsys_gw']").text("Payment in installments");
    }
});

but it only changes it for a moment and returns to the default title, is there any way to do it in the functions.php with some hook?

Answer 1

You can use this simple hooked function, where you will have to set the correct targeted payment id and the targeted product id(s):

add_filter( 'woocommerce_gateway_title', 'change_payment_gateway_title', 100, 2 );
function change_payment_gateway_title( $title, $payment_id ){
    $targeted_payment_id  = 'redsys_gw'; // Set your payment method ID
    $targeted_product_ids = array(37, 53); // Set your product Ids

    // Only on checkout page for specific payment method Id
    if( is_checkout() && ! is_wc_endpoint_url() && $payment_id === $targeted_payment_id ) {
        // Loop through cart items
        foreach( WC()->cart->get_cart() as $item ) {
            // Check for specific products: Change payment method title
            if( in_array( $item['product_id'], $targeted_product_ids ) ) {
                return __("Payment in installments", "woocommerce");
            }
        }
    }
  return $title;
}

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