Help with if... else... loop

[turtleton09]

Hope someone can help with this.

I've basically inherited a site with a shopping cart, which has a couple of optional extras on products - paintwork and cushions.

I've been asked to add in a third optional extra, glasstops.

At the moment there is a little if... else... loop which determines wether or not the relevant pages for those extras are displayed.

So, at the moment it goes > products.php > paintwork.php (if the paintwork field is not empty) > accessories.php (if the accessories field is not empty).

That code looks like :

      foreach ($_SESSION["basket"]["items"] as $key => $value) {
        if ($value["product"] == $_POST["id"]) {
          //$sql = "SELECT `cushions` FROM `products` WHERE `id` = '" . $value["product"] . "'";
          //$result = mysql_query($sql) or die("Query failed : $sql at line " . __line__);
		  if (!@empty($row["paintwork"])) {
		    $redirect = "paintwork.php?id={$key}";
		  } elseif (!@empty($row["cushions"])) {
		    $redirect = "shopping_cart.php";
		  } else {
			$redirect = "accessories.php?id={$key}";
		  }
          header("location: {$redirect}");
	      exit;
		}

I've created a glasstop.php page, and changed that to :

      foreach ($_SESSION["basket"]["items"] as $key => $value) {
        if ($value["product"] == $_POST["id"]) {
          //$sql = "SELECT `cushions` FROM `products` WHERE `id` = '" . $value["product"] . "'";
          //$result = mysql_query($sql) or die("Query failed : $sql at line " . __line__);
		  if (!@empty($row["glasstop"])) {
		    $redirect = "glasstop.php?id={$key}";
		  } elseif (!@empty($row["cushions"])) {
		    $redirect = "shopping_cart.php";
		  } else {
			$redirect = "accessories.php?id={$key}";
		  }
          header("location: {$redirect}");
	      exit;
		}

which is fine, but haven't quite been able to get it to work with all three - the closest I've got without errors is :

foreach ($_SESSION["basket"]["items"] as $key => $value) {
        if ($value["product"] == $_POST["id"]) {
          //$sql = "SELECT `cushions` FROM `products` WHERE `id` = '" . $value["product"] . "'";
          //$result = mysql_query($sql) or die("Query failed : $sql at line " . __line__);
		  if (!@empty($row["paintwork"])) {
		    $redirect = "paintwork.php?id={$key}";
		  } elseif (!@empty($row["glasstop"])) {
		    $redirect = "glasstop.php?id={$key}";
		  }
		  elseif (!@empty($row["cushions"])) {
		    $redirect = "shopping_cart.php";
		  } else {
			$redirect = "accessories.php?id={$key}";
		  }
          header("location: {$redirect}");
	      exit;
		}

If anyone could help out with this that would be much appreciated.

Thanks.
