How to add Buy Now button in cs-cart - php

Question

I'm creating a buy-now button cs-cart add-on. I've created an add-on and I've made the add-to-cart functionality work. But cant redirect it to checkout page. I have used "fn_redirect("checkout")" function for the redirection. And used this function below this:
"fn_add_product_to_cart($_REQUEST['product_data'], $cart, $auth);"
What should I do for redirection?
Edit:
My controller (buy_now.php)
if ($mode == 'add') {
if (empty($auth['user_id']) && Registry::get('settings.General.allow_anonymous_shopping') != 'allow_shopping')
{
return array(CONTROLLER_STATUS_REDIRECT, "auth.login_form?return_url=" . urlencode($_REQUEST['return_url']));
}
// Add to cart button was pressed for single product on advanced list
if (!empty($dispatch_extra)) {
if (empty($_REQUEST['product_data'][$dispatch_extra]['amount'])) {
$_REQUEST['product_data'][$dispatch_extra]['amount'] = 1;
}
foreach ($_REQUEST['product_data'] as $key => $data) {
if ($key != $dispatch_extra && $key != 'custom_files') {
unset($_REQUEST['product_data'][$key]);
}
}
}
$prev_cart_products = empty($cart['products']) ? array() : $cart['products'];
fn_add_product_to_cart($_REQUEST['product_data'], $cart, $auth);
fn_save_cart_content($cart, $auth['user_id']);
$previous_state = md5(serialize($cart['products']));
$cart['change_cart_products'] = true;
fn_calculate_cart_content($cart, $auth, 'S', true, 'F', true);
if (md5(serialize($cart['products'])) != $previous_state && empty($cart['skip_notification'])) {
$product_cnt = 0;
$added_products = array();
if (!empty($added_products)) {
Registry::get('view')->assign('added_products', $added_products);
if (Registry::get('config.tweaks.disable_dhtml') && Registry::get('config.tweaks.redirect_to_cart')) {
Registry::get('view')->assign('continue_url', (!empty($_REQUEST['redirect_url']) && empty($_REQUEST['appearance']['details_page'])) ? $_REQUEST['redirect_url'] : $_SESSION['continue_url']);
}
fn_redirect(Registry::get('config.https_location') . "/checkout");
// $msg = Registry::get('view')->fetch('views/checkout/components/product_notification.tpl');
//fn_set_notification('I', __($product_cnt > 1 ? 'products_added_to_cart' : 'product_added_to_cart'), $msg, 'I');
$cart['recalculate'] = true;
} else {
fn_set_notification('N', __('notice'), __('product_in_cart'));
}
}
unset($cart['skip_notification']);
$_suffix = '.checkout';
}
`
hook template : add_to_cart.post.tpl
{$id = "buy_now_{$product.product_id}"}
<button id="opener_{$id}" name="dispatch[buy_now.add..{$product.product_id}]" class=" vs-button buynow_btn_">Buy Now</button>

I'd consider putting your fn_redirect("checkout") code into an if/else statement to see what's happening with it.
If you have this code:
fn_add_product_to_cart($_REQUEST['product_data'], $cart, $auth);
Then surely you can put the redirection to the checkout page underneath it?
$redirect_url = "http://testcheckout.com?test=test"; //change this!
$errorMessage = "I should have redirected already....";
if (!empty($redirect_url)) {
//if it's not empty then it should redirect.
fn_redirect($redirect_url);
//Then put a die statement in here just to check it's not executing
//anything else and you can see if the redirect has a problem:
die(print_r($errorMessage, true ));
}
else {
//otherwise there is a problem with the supplied redirect url (empty)
die(print_r($redirect_url, true ));
}
I'd also take a look at this page which might help more:
