Jcart - Display variable outside of the cart

Hi,

I'm using the jcart shopping cart script and want to determine whether the cart is empty outside of the file structure of jcart. The jcart.php (attached) sits within a folder jcart and the file I'm trying to determine whether the cart is empty is up one level. Looking on the jcart support forum (http://conceptlogic.com/jcart/help/viewtopic.php?f=3&t=1163) it suggests adding the following to the jcart file:

public function get_total_quantity() {
  $qty = 0;
  foreach($this->items as $item) {
    $qty += $this->qtys[$item];
  }
  return $qty;
}

Open in new window


and then adding the following to the external file:

<p>There are <?php $jcart->get_total_quantity(); ?> items in your cart.</p>

Open in new window


This however, doesn't appear to work. I would like to assign the value this produces to a variable so the that:

if($cart>0){
do this }
else{
do that};

Open in new window


Any help would be greatly appreciated. Thank you

greetings  bootneck2222, , ,  Not sure about some of what you are asking about, , but in this line of code -
    There are <?php $jcart->get_total_quantity(); ?> items in your cart.

the PHP part is NOT setup to output anything, you need to have a PHP html output like  echo  in it, like this -
     There are <?php echo $jcart->get_total_quantity(); ?> items in your cart.

You say - "I would like to assign the value this produces to a variable so the that", But you don't give much about what it does?

Anyway , here's my suggestion, up above the output line in the PHP code you might try to have code -
<?php
 
$total = $jcart->get_total_quantity();
if ($total) {
   $cartTotal = 'There are '.$total.' items in your cart.';
   } else {
   $cartTotal = 'ERROR: You must first add Items to your cart';
   }

?>

Open in new window


and then down in the paragraph <p> part have -
      <p><?php echo $cartTotal ?></p>

Thanks Slick812. It was a long day on Friday. Missing the echo was a schoolboy error. #Doh!

The $cartTotal variable assignment was right on too.

Thank you
