Variables when adding to cart


Recommended Posts

Hi everyone,


I'm currently using a combination of Add quantity box to product info page and Shopping Cart as Tooltip.


The first allows for more than 1 of each product to be added to the shopping cart, whilst the second is a popup confirming entry of item going into the cart.


I've modified the second one to show more information of purely the item being added to the cart. I want Product Name, Quantity, Cost... but currently I've been only able to retrieve the name via the variable $product_info['products_name'].. but I can't find how to pass the other 2 variables into this script.


The modified code for the quantity contrib is as below:



     // customer adds a product from the products page
     case 'add_product' :    if (isset($_POST['products_id']) && is_numeric($_POST['products_id'])) {
			if (tep_has_product_attributes($_POST['products_id']) && PRODUCT_LIST_OPTIONS != 'true' && basename($PHP_SELF) != FILENAME_PRODUCT_INFO) tep_redirect(tep_href_link(FILENAME_PRODUCT_INFO, 'products_id=' . $_POST['products_id']));
			$add_quantity = (isset($_POST['cart_quantity']) ? (int)$_POST['cart_quantity'] : 1);
                               $cart->add_cart($_POST['products_id'], $cart->get_quantity(tep_get_uprid($_POST['products_id'], $_POST['id']))+$add_quantity, $_POST['id']);
                             tep_redirect(tep_href_link($goto, tep_get_all_get_params($parameters)));



                <td class="main" align="right"><?php 
			///  product quantity drop down
			$product_quantity = tep_get_products_stock($_GET['products_id']);
			if ($product_quantity > MAX_QTY_IN_CART) { $product_quantity = MAX_QTY_IN_CART ; } ;
			$products_quantity_array = array();
			for ($i=1; $i<=$product_quantity; $i++) {
			$products_quantity_array[]=array('id' => $i, 'text' => $i); };
echo tep_draw_hidden_field('products_id', $product_info['products_id']) . TEXT_PRODUCT_QUANTITY . tep_draw_pull_down_menu('cart_quantity',$products_quantity_array,1) . '  ' . tep_image_submit('button_in_cart.gif', IMAGE_BUTTON_IN_CART); ?></td>
<!-- product quantity drop down -->



If anyone has any ideas, this would be most greatly appreciated!!

I'm still struggling with this, so if anyone has any clues that would be most useful! Thanks :D

As far as I know there are only two ways to pass variables from page to page.


1. Thru the URL string, like:



Doing it that way you can retrive it's value thru code like this:


$your_variable = $HTTP_GET_VARS['products_id'];


2. Make it a session variable. Code similar to this:


  $your_variable = SOME_VALUE;
 if ( ! tep_session_is_registered('your_variable') ) {

Then on the "other page" you just reference it with $your_variable


Doing it thru the URL string can be "risky" with some things because people can manually type whatever they want into the browser address bar, or alter whatever is there. Keep that in mind.




If I suggest you edit any file(s) make a backup first - I'm not perfect and neither are you.
