Setting up new error at checkout

[abcisme]

I have a dropdown box enabled on my checkout page. When a customer hasn't selected something from the dropdown, I need to redirect them to the checkout payment page and show them an error message.

Here's what I have put for code in my checkout_confirmation header.php:

if (!isset($_SESSION['dropdown'])) {
  
$messageStack->add_session('dropdown', ERROR_DROP_DOWN, 'error'); 

zen_redirect(zen_href_link(FILENAME_CHECKOUT_PAYMENT, '', 'SSL'));
  
}

It kicks it back to the payment page, but doesn't show the error message. Can anyone help me correct where I've gone wrong?

When you do a messageStack you have to add it to an existing output on the page ...

The tpl_checkout_payment.php has a few:

<?php if ($messageStack->size('redemptions') > 0) echo $messageStack->output('redemptions'); ?>
<?php if ($messageStack->size('checkout') > 0) echo $messageStack->output('checkout'); ?>
<?php if ($messageStack->size('checkout_payment') > 0) echo $messageStack->output('checkout_payment'); ?>

If you change your messageStack from:

$messageStack->add_session('dropdown', ERROR_DROP_DOWN, 'error');

to something like:

$messageStack->add_session('checkout_payment', ERROR_DROP_DOWN, 'error');

it should work better ...

Figured it out. OOPS.

if (!isset($_SESSION['dropdown'])) {
  
$messageStack->add_session('checkout_payment', ERROR_DROP_DOWN, 'error'); 

zen_redirect(zen_href_link(FILENAME_CHECKOUT_PAYMENT, '', 'SSL'));
  
}

Yep. That was it. First time I had ever done it, so I wasn't sure about the coding. Learned something new today.
