Need help outputting shopping cart form a foreach loop

[eldan88]

Hey Guys. I crearted a class that goes loops through the session cart and displays the items. The problem that I am facing is when a return the values from a method it only brings back the first item that was added to the cart. It doesn't out out all the values.

 

However when I echo the the values straight from inside the method it shows all the items it looped through. I have tried every possibly thing to have all the items be displayed but I couldn't find to seem a solution.

 

Please note that I skipped a lot of the code in the example below for breviety. Such as instantiation, and other things. There maybe some syntax errors as well. I just did a breif copy and paste

 

 

Any help would be really appreciated!!!

class coreCartFunctions {

protected function DisplayMenuItems($menu_item_id_session){
	  $qty_output =  "<span style=\"font-size:18px\">X{$this->item_qty}</span>";
      $this->menu_item_name = $this->getItems($this->menu_item_id,"menu_item_name");

           if($this->DisplayPrice()){


             $update_order_url ="item-detail.php?update_order=true&menu_item_id={$menu_item_id_session}
             &callback_url={$this->url}&store={$_SESSION['store_name']}";

             $output =  "<a class='{$this->menu_items_class_prop_a}' href='{$update_order_url}'>
             <div class='{$this->menu_items_class}'>{$qty_output} {$this->menu_item_name}</div>";
             $output .= "<div class='menu_item_price'>\${$this->menu_item_price}</div></a>";
             return $output;
             } else {
             $output = "<a class='{$this->menu_items_class_prop_a}' href='#'><div class='menu_item_name'>"
              .$qty_output." ".$this->menu_item_name ."</div></a>";
             return  $output;
          }



}


class displayCartItems extends coreCartFunctions {

public function GetMenuItems() {

foreach ($this->items as $menu_item_id_session) {
 //assign all the properties that belong to core class

 $output = $this->DisplayMenuItems($menu_item_id_session);
return $output
}


}

$display_items =  $display_menu_item->GetMenuItems();
echo $display_items

Because you are returning your function inside the loop.

 

Also, you aren't concatenating $output, you're just overwriting it every time.

Hey Zane! I kinda get what you are saying. How can return all  the values outside of the function??

[eldan88]

Hey Zane! Never mind i got it.  What I did is I initiated the $output  with a $output = "" variable outside the the foreach loop and returned it also outside the foreach loop. Thanks alot man!

P.S i replied back to your email.
