Ok, This is driving me nuts. I'm sure its something simple but I can't seem to find the glitch.
I'm trying to make a simple shopping cart using Session varibles to store the item => quantity pairs, then I loop thru the cart and query the db to get the item details, etc.. Most of it works fine but whenever I add a new item to the cart I lose the $qty value for the other items. Here is the code in question: ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ <? session_start(); include 'inc/common.inc.php'; if (!session_is_registered("cart")) { $cart = array(); session_register("cart"); $items = 0; session_register("items"); } if($cart[$new]) { $cart[$new]++; }else{ $cart[$new] = 1; } foreach ($cart as $id => $qty) { if ($$id == "0") { unset ($cart[$id]); }else{ $cart[$id] = $$id; } $items = calculate_items($cart); foreach ($cart as $id => $qty){ $db = mysql_connect("localhost", "$databaseuser", "$databasepasswd") or die ("Unable to connect to database!"); mysql_select_db ("$databasename",$db) or die ("Unable to connect to database $db!"); $result = mysql_query ("SELECT * from products WHERE id = '$id'") or die ("Error in query. " . mysql_error()); if ($result){ extract(mysql_fetch_array($result)); echo "<b>Title:</b> $title<br />"; echo "<b>Description:</b> $p_desc<br />"; echo "<b>Price:</b> $price<br />"; echo "<b>Quantity:</b> $qty<br />"; echo "<hr />"; } } #print varibles to screen for debugging echo"<pre>"; print_r($HTTP_SESSION_VARS); echo"</pre>"; ?> +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ If one item is in the cart I get this from the $HTTP_SESSION_VARS: Array ( [cart] => Array ( [10] => 12 ) [items] => 12 [total_price] => 0.00 ) That would indicate to me that the cart pair has been saved. But as I add items I lose the earlier quantities: Array ( [cart] => Array ( [10] => [16] => [13] => 6 ) [items] => 6 [total_price] => 0.00 ) The $id is still there and I can query the db just fine, but no quantity. I don't know why this is eluding me but any help would be greatly appreciated. Thanks, Robert -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
