Which php variable calls for Total Items in Cart?

[samar777]

I am trying to do something like this on tpl_shopping_cart_default.php

if ( $cart_quantity == "1" ) {
	echo "Did you know a second box will ship for free!<br />";
}
?>

is that right? When there is only one item in shopping cart, I want to display the message above.

is the variable $cart_quantity right for the number of items in cart?

( My first attempt at php, be gentle )

Assuming that "only one" in the shopping cart means that there's only 1 item of any type/product, then what you want is:

if ($_SESSION['cart']->count_contents() == 1) {
  echo "Did you know a second box will ship for free!<br />";

}

... of course, it's always good practice to put language-specific stuff in a language file! You could add to /includes/languages/english/YOURTEMPLATE/shopping_cart.php:

define('CART_2ND_FOR_FREE', 'Did you know a second box will ship for free!<br />');

and then change your template code to

if ($_SESSION['cart']->count_contents() == 1) {
  echo CART_2ND_FOR_FREE;

}

You are awesome. I have been reading php resources all day to achieve this. Thank you.

It works perfectly.

Yup!

Now, with the same statement how can i put another part in there.

if total items in cart are 3 , display "did you know the 4th box ships free"

and

If total item are more between than 4 but less than 12, " did you know upto 12 boxes ship at no extra charge"


( of course i will use proper text and define files)

Sure, here you go (with 'hard-coded' language):

$itemsInCart = $_SESSION['cart']->count_contents();
if ($itemsInCart == 1) {
  echo "Did you know a second box will ship for free!<br />"; 
} else if ($itemsInCart == 3) {
  echo 'Did you know a fourth box will ship for free!<br />';
} else if ($itemsInCart > 4 && $itemsInCart < 12) {
  echo 'Did you know that up to 12 boxes ship at no extra charge?<br />';
}
