Jason, Thx. Even though I have what I need for the client (I finally got things to work as desired), I'll rework it and update the client version. I knew I was doing things poorly and it degenerated into simply "get the damn thing to work."

It appears that your overall problem is a misunderstanding of how arrays work in PHP and how easy it is to manipulate them. First: > if (session_is_registered('ses_basket_items')){ In general, for practical purposes (if PHP is installed using the recommended default setup, ie register_globals disabled), session_is_registered() is deprecated and should not be used. Use: if (isset($_SESSION['ses_basket_items'])) { ... }; Second: > if ($action == "empty") > { > while ($ses_basket_items > -1) > { > array_splice ($ses_basket_name, > $ses_basket_items, 1); > array_splice ($ses_basket_amount, > $ses_basket_items, 1); > array_splice ($ses_basket_price, > $ses_basket_items, 1); > array_splice ($ses_basket_id, > $ses_basket_items, 1); > $ses_basket_items--; > } > } You seem to be using multiple single dimension arrays to store your basket details. That is not the optimal way of doing things. You should have a *single* multi dimension array, there are many ways to do this, here's a couple: 1) $basket[1] = array('name' => 'name of product', 'id' => 'product id', 'price' => 'price of product', 'amount' => 'quantity required'); $basket[2] = array('name' => 'name of product', 'id' => 'product id', 'price' => 'price of product', 'amount' => 'quantity required'); 2) $basket['a_product_id'] = array('name' => 'name of product', 'price' => 'price of product', 'amount' => 'quantity required'); $basket['another_product_id'] = array('name' => 'name of product', 'price' => 'price of product', 'amount' => 'quantity required'); OK, so how do you operate on them? In the examples below 2 forms will be given corresponding to how you defined the arrays as per above. To remove an item: 1) unset($basket[n]); // where n is an integer 2) unset($basket['product_id']; // if product_id is an integer // then you don't need the single-quotes // note that also applies when first // define the array, ie: // $basket[product_id] = array(...); To change an attribute, eg the amount: 1) $basket[n]['amount'] = 5; 2) $basket['product_id'] = 10; To display an attribute, eg price: 1) echo $basket[n]['price']; 2) echo $basket['product_id']['price']; When playing around with arrays, print_r() is your friend, use it liberally. -- Jason Wong -> Gremlins Associates -> www.gremlins.biz Open Source Software Systems Integrators * Web Design & Hosting * Internet & Intranet Applications Development * ------------------------------------------ Search the list archives before you post http://marc.theaimsgroup.com/?l=php-general ------------------------------------------ New Year Resolution: Ignore top posted posts -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
