> if (isset($_REQUEST['clear']))

>

> {

> $shopping_cart->EmptyCart();

> echo render_notification('

Shopping Cart

> Emptied

');

> $check_if_empty = "";

>

> }else{

Looks like you are pretty close to having it work... you shouldn't need to place it in a function, just add something like this in the spot in your file where the button will appear:

 

If (empty($cart)){

// if cart is already empty, don't display the button (or take another action -- I'm not sure what you had min mind)

}else{

// cart isn't empty, display the "clear basket" button

}

Hi all got it working not the best way it can be done i think but it works, i figured the reason it wasnt working is that the cart isnt empty and it isnt the default string length is 45 so i just said count the string length if its more than 45 then show the button and sure enough its working, now to count the total products in cart hehe, code below:

 

function render_empty_cart_btn()//Checks if the cart is empty by counting the string length, if the string length is longer than the default length of 45 then it adds the empty cart button.
{
   $cart = ($_SESSION['cart']);
   if(strlen($cart) > 45)
   {
   echo"Empty Cart



";
   }else{

       echo"



";
   }
}

Just be aware that this statement is incorrect:

 

echo"

Empty Cart

 

elements need to go inside

's. This is correct:

 

echo"

Empty Cart
