Simple Cart Compliance Checkbox

Hi Perch,

Add this to the bottom of your customCart.php:

addFilter('sc_order_final_validation', 'my_final_validation', null, 3);
function my_final_validation($errorsAndAlerts, $orderNum, $order) {
  if (!@$_REQUEST['agree']) {
    $errorsAndAlerts .= "You must agree to the terms!<br>\n";
  }
  return $errorsAndAlerts;
}

Hope this helps!

Hi, Chris -

Thanks for this. I added the code as suggested - and added a checkbox to the order page. Sadly however, it doesn't seem to have any effect on the process. The order proceeds to PayPal whether the box is ticked or not!

Hi Perch,

What are your $GLOBALS['SC_PAYMENT_PROCESSOR_FUNCTION'] and/or $GLOBALS['SC_ORDER_OVERRIDE_FUNCTION'] set to?

Hi, Chris -

$GLOBALS['SC_ORDER_OVERRIDE_FUNCTION']      = 'payPalStandard_simpleCartCheckout';

$GLOBALS['SC_PAYMENT_PROCESSOR_FUNCTION'] isn't set.

Thanks,

Perch

A ha! It looks like the payPalStandard plugin is missing the sc_order_final_validation plugin hook. Please edit payPalStandard.php, search for "_sc_validateOrderRequest", and add the code in red below after it:

  //Simple Cart validation task
  $errorsAndAlerts = _sc_validateOrderRequest($order);
  if ($errorsAndAlerts) { return $errorsAndAlerts; }

  // last-chance order validation before payment (e.g. for inventory remaining checks)
  $errorsAndAlerts = applyFilters('sc_order_final_validation', '', $order['num'], $order);
  if ($errorsAndAlerts) { return $errorsAndAlerts; }


  list($grandTotal, $subTotal, $extraLineItems, $cartItems) = sc_tallyCart($order['num']);

I've added this to our development branch of the plugin, so it will appear in the next version released.

Does that help?

Hi, Chris -

Perfect. It works now.

If I wanted to go the extra mile - and I always do - how could I print this particular error message at the bottom of the page (where the compliance checkbox is located)?

I supose I'm asking, how do you break apart the $errorsAndAlerts array into it's component parts?

Hi Perch,

$errorsAndAlerts is intended to be used as a string so that it can easily be injected into the top of a page. I think the approach I would take would be to extract the specific error message from $errorsAndAlerts and set a true/false flag for that one field, then check for the flag later down the page:

<?php

$messageToSearchFor = "You must agree to the terms!<br>\n";
$termsCheckboxError = contains($messageToSearchFor, $errorsAndAlerts); // look for the specific error message
if ($termsCheckboxError) {
  $errorsAndAlerts = str_replace($messageToSearchFor, '', $errorsAndAlerts); // remove the specific error message
}

?>

<?php if ($errorsAndAlerts): ?>
  Errors: <?php echo $errorsAndAlerts ?>
<?php endif ?>

...

<input type="checkbox">
<?php if ($termsCheckboxError): ?>
  Please check the box!
<?php endif ?>

Does that help?
