'..' : $option['option_value'])             );         } 

any suggestions on causing this?

you cant use $this->cart->getproducts(); in foreach loop.

so need assign value variable

$products = $this->cart->getproducts();

this little line of code important in makes call function getproducts core procedure located in system/library/cart.php. variable $products has entire cart array + possible options , can “iterated” through. iterate means sift through array, gathering it’s contents or loop through. let’s take @ happening in function getproducts(); in system/library/cart.php find function towards top: use in foreach loop

foreach ($products $product)  {    //your code here } 

this code foreach() loop set go through array set in system/library/cart.php. responsible displaying of content seen in shopping cart page along product options. below foreach ($products $product) { repeat many times necessary until products have been dealt in array.

this work fine.

public function getproducts() {     if ( !$this->data )     {         foreach ( $this->session->data['cart'] $key => $quantity )         {             $product = explode(':', $key);             $product_id = $product[0];             $stock = true;// options             if ( isset($product[1]) )             {                 $options = unserialize(base64_decode($product[1]));             }             else             {                 $options = array();             }         }     } }
